How to enable the develop menu in safari on mac, how to view page source in safari on mac.

When you right-click on any web page in Safari on Mac, it doesn't reveal the Show Page Source and Inspect Element buttons. To see these, you need to enable the Develop menu---we'll show you how to do that.

Once you've enabled the Develop menu, right-clicking a blank space on any website will reveal the Inspect Element and Show Page Source buttons. These allow you to take a look at the source code of any website, which is useful for things like downloading images from websites and debugging code or finding out what it looks like behind any site (for website designers).

You can easily turn on the Develop menu in Safari by following a couple of steps. Open Safari on your Mac and click the "Safari" button in the menu bar.

Next, select "Preferences." Alternatively, you can use the keyboard shortcut Command+, (comma). This will also open up Safari preferences.

Go to the "Advanced" tab.

Check the box for "Show Develop Menu in Menu Bar."

Now the Develop menu will appear between Bookmarks and Window at the top.

Apart from being able to view the page source, this will allow you to access developer-focused features, such as disabling JavaScript on any website.

Once you've enabled the Develop menu, there are a couple of ways to view the page source in Safari.

Open any website in Safari and right-click the blank space on the page. Now, select "Show Page Source." You can also get to this menu by using the keyboard shortcut Option+Command+u.

If you're looking for images or other media elements from any web page, Safari makes it easy to find these. In the left-hand pane, you will see various folders such as Images, Fonts, etc. Click the "Images" folder to quickly find the photos that you need.

After selecting an image, you can view its details easily by opening up the details sidebar. The button to open this is located at the top-right of the console, just below the gear icon. You can also open this with the shortcut Option+Command+0.

Click "Resource" at the top of the details sidebar to view details, such as the size of the image and its full URL.

You can change the position of the page source console easily, too. There are two buttons at the top-left of this console, right next to the X button. Click the rectangle icon to move the console to a different side within the browser window.

If you'd like to open the page source console in a separate window, you can click the two-rectangles icon. This will detach the console and open it in a separate window.

To check out the code for any specific element on the page, you can right-click that element and select "Inspect Element." This will take you directly to the code for the element that you selected.

Whenever you're done looking at the code, click the X button to close the page source console and return to browsing on Safari. You can also check out how to view a website's page source in Google Chrome  here.

How To Open Developer Tools On Mac

Are you a Mac user who needs to access developer tools? Developer tools are essential for web developers, as they allow you to monitor and debug your code. Whether you are a novice or an experienced programmer, it is important to understand how to open and use developer tools on your Mac.

The first step in accessing developer tools on your Mac is enabling the Develop menu. To do this, open Safari > Preferences > Advanced > Show Develop menu in the menu bar. Once this option is enabled, the Develop menu will appear between Bookmarks and Windows in the Safari menu.

The most useful options within the Develop menu are Open Page With, User Agent, and Empty Caches. Open Page With allows you to view webpages with different web browsers such as Firefox or Chrome. This is especially useful for testing websites across different browsers. The User-Agent option lets you change the user-agent string of your browser to simulate other devices or browsers. This can be beneficial for debugging cross-browser compatibility issues. Finally, Empty Caches clears all cached images and data from any web pages that have been visited recently in Safari.

Another way of opening developer tools on a Mac is via keyboard shortcuts. Most browsers support F12 as a shortcut to open dev tools; however, Internet Explorer and Edge require Ctrl + Shift + I instead. Additionally, for Firefox users, pressing and holding/right-clicking any item on a webpage (Ctrl-click on the Mac) will bring up a context menu from which you can select Inspect Element to open dev tools.

Whether you are developing a website or troubleshooting existing code, it is important to know how to access developer tools on your Mac quickly and easily so that you can get the job done efficiently!

Bringing Up Developer Tools on Mac

To bring up Developer Tools on Mac, open the Safari browser and go to the menu bar. You should see a “Develop” menu. If not, select Safari > Settings, click Advanced, and make sure to check the box for “Show Develop menu in the menu bar.” Once the Develop menu is visible, click on it and select “Show Web Inspector” or “Show Error Console.” This will open up a window with a range of tools you can use to debug and test your website for compatibility with web browsers.

Accessing F12 Developer Tools on a Mac

In order to get F12 Developer Tools on your Mac, you will need to open up System Preferences > Keyboard. Once there, check the box marked “Use all F1, F2, etc. keys as standard function keys”. Then head to the Shortcuts tab, and select App Shortcuts from the side menu. From here, you can add a shortcut for Chrome Developer Tools by clicking the “+” button and entering “Chrome” into the Application field. Select Chrome from the drop-down list that appears and then types in “F12” in the Keyboard Shortcut field. After this is done, you should be able to open Chrome Dev Tools with just F12 on your Mac.

Opening Developer Tools

To open Developer Tools, you can use your keyboard, menu bar, or context menu. On most browsers, you can press the keyboard shortcut Ctrl + Shift + I to open Developer Tools. If you’re usng Firefox, you can go to the Menu bar and select “Tools” and then “Web Developer.” If you’d prefer to use the context menu, press-and-hold/right-click an item on a webpage (Ctrl-click on Macs), and select “Inspect Element” from the context menu that appears. If you’re using Internet Explorer or Edge, the keyboard shortcut is F12.

Opening the Developer Tab in Safari

To open the Develop tab in Safari, you first need to enable it. To do this, go to the Safari menu and select ‘Preferences’. In the Preferences window, select ‘Advanced’ and then check the box next to the ‘Show Develop’ menu in the menu bar’. Once you have enabled the Develop tab, it will appear between Bookmarks and Windows in the Safari menu.

Once you click on Develop, you will be able to access some of its most useful options such as ‘Open Page With’, ‘User Agent’, and ‘Empty Caches’. With Open Page With, you can test what a web page looks like when opened with a different browser or device. User Agent allows you to view a web page as if it was being viewed by another type of device (e.g. iPhone or Android). Finally, Empty Caches allows you to delete any stored website data from your computer.

Opening Developer Tools in Chrome on Mac

To open the Developer Tools in Chrome on Mac, open the Chrome Menu in the upper-right-hand corner of the browser window and select More Tools > Developer Tools. Alternatively, you can use the keyboard shortcut Option + ? + J to open the Developer Tools. Once opened, you will have access to multiple panels that allow you to inspect HTML and CSS elements on a web page, view console messages, view logged network requests, and profile JavaScript performance.

Inspecting on Mac

If you’re using a Mac, you can inspect elements on a webpage by right-clicking the page and selecting ‘Inspect Element’. Alternatively, you can press Command+Option+i on your keyboard to open the same inspection window. This will open up a new window that displays all the HTML and CSS associated with the page. From here, you can view and edit elements of the page, as well as view any errors in your code. You can also use this window to find out more about how the page is structured and how it works.

Developer tools are essential for web developers, as they provide the necessary tools and information to ensure their websites are working correctly and meeting all standards-based web browser requirements. With the Safari Develop menu, developers can open Chrome Dev Tools with just F12 on a Mac, access Firefox’s menu bar, use the context menu for inspecting elements, and more. Additionally, important developer options such as Open Page With, User Agent, and Empty Caches can be found in the Safari Develop Menu. With these tools at their disposal, developers can easily debug their websites and create optimized user experiences.

WebKit Features in Safari 18.0

Sep 16, 2024

by Jen Simmons

New in Safari 18

Web apps for mac, spatial web, managed media source, web inspector, safari extensions, deprecations, bug fixes and more, updating to safari 18.0.

Safari 18.0 is here. Along with iOS 18, iPadOS 18, macOS Sequoia and visionOS 2, today is the day another 53 web platform features, as well as 25 deprecations and 209 resolved issues land in WebKit, the rendering engine driving Safari.

Distraction Control

Distraction Control lets you hide distracting items as you browse the web, such as sign-in banners, cookie preference popups, newsletter signup overlays, and more, in Safari for iOS 18, iPadOS 18 and macOS Sequoia.

We always recommend using semantic HTML when creating a website, including <video> , <main> , <article> and other elements that describe content. Doing so helps ensure both Safari Reader and Safari Viewer work best for the users of your website.

iPhone Mirroring and remote inspection

With iPhone Mirroring on macOS Sequoia, you can use your iPhone from your Mac. Combine it with remote inspection from Safari, and now it’s easier than ever to test and debug websites on iOS using Web Inspector .

Get set up for remote inspection by first ensuring you have Safari’s developer tools enabled on your Mac (if you can see the Develop menu in Safari, you’ve already done this step). Next, enable Web Inspector on your iPhone at Settings > Apps > Safari > Advanced > Web Inspector. Then, you’ll need to connect the device to your Mac using a cable to grant permission. Once plugged in, your device will appear in the Develop menu in Safari. Finally, to enable wireless debugging, go to Safari on macOS > Develop > [your device] > Connect via Network.

Now you can use Web Inspector to wirelessly debug websites running on iPhone anytime. And with iPhone Mirroring, you don’t even have to pull out your phone. Everything is on your Mac’s screen.

Learn more about remote inspection by reading Inspecting iOS and iPadOS , or by watching Rediscover Safari developer features from WWDC. Learn more about iPhone Mirroring 1 on apple.com .

Last year , we added support for web apps in macOS Sonoma. You can add any website to your dock — whether or not it was built with a Manifest file, Service Worker, or other technology to customize the web app experience. Go to the site in Safari, then File > Add to Dock… where you can customize the icon, change the name, and even adjust the URL. Then, just click on the web app icon in your Dock, and the website will open as a stand-alone app.

This year brings two improvements to web apps on Mac.

Opening links

macOS Sequoia adds support for opening links directly in web apps. Now, when a user clicks a link, if it matches the scope of a web app, that link will open in the web app instead of their default web browser. For example, imagine you have added MDN Web Docs to your Dock. Then a colleague sends you a link to an MDN page in Messages, Mail, Slack, Discord, IRC, or any non-browser application on your Mac. Now when you click on that link, it will open in the MDN Web Docs web app instead of your default browser.

Clicking a link within a browser will maintain the current behavior. This feature only affects links opened elsewhere. (When a user is in Safari, clicking on a link that matches the scope of a web app that is added to Dock, they will see an “Open in web app” banner, unless they have previously dismissed the banner.)

By default, this behavior applies when the link matches the host of the web page used to create the web app. As a developer, you can refine this experience by defining the range of URLs that should open in the web app with the scope member in the web app manifest .

Extension support

Now users can personalize web apps on Mac with Safari Web Extensions and Content Blockers. Navigate to the web app’s Settings menu to access all the installed Content Blockers and Web Extensions. Any enabled in Safari will be on by default in the web app. Each web app is uniquely customizable, just like Safari profiles.

View Transitions

WebKit added support for the View Transitions API in Safari 18. It provides an optimized browser API to animate elements from one state to another. Safari supports the CSS View Transitions Module Level 1 specification that adds new CSS properties and pseudo-elements for defining transition animations, along with a new browser API to start transition animations and react to different transition states. It works by capturing the current (old) state of the page and applying an animated transition to the new state. By default, the browser applies a cross-fade between the states.

Call the document.startViewTransition() method to initiate the capture. You can pass a callback function as the first argument to make DOM state changes between the old and new captures. The method returns a ViewTransition object which contains promises that can be used to track when the view transition starts or ends.

Once the states are captured, a pseudo-element tree is built which can be targeted with CSS, allowing you to modify the CSS animations used for the transitions. The animations out of the old page state and into the new page state can be modified via the ::view-transition-new(*) and ::view-transition-old(*) selectors. You can also ask the browser to independently track state changes for a specific element by naming it with the CSS view-transition-name property. You can then use the pseudo-elements to customize animations for it.

The :active-view-transition pseudo-class becomes active on the root element when a view transition is running.

The example below demonstrates state management with tabbed navigation. Each tab view has a custom transition animation out and a subtly different animation in, while the tabs themselves rely on the default page transition.

Style Queries

WebKit for Safari 18.0 adds support for Style Queries when testing CSS Custom Properties. Similar to how developers can use Sass mixins, Style Queries can be used to define a set of reusable styles that get applied as a group.

Here, if the --background custom property is set to black, then certain styles will be applied — in this case to make the headline and paragraph text color white.

Don’t forget to pay attention the HTML structure. By default, Style Queries reference the styles on the direct parent element. You can create a different reference through the use of Container Query names.

currentcolor and system color keywords in Relative Color Syntax

Support for Relative Color Syntax shipped in Safari 16.4 . It lets you define colors in a more dynamic fashion, creating a new color from an existing color. The value lch(from var(--color) calc(L / 2) C H) for instance uses the lch color space to take the variable --color and calculate a new color that’s half its lightness, calc(L / 2) .

Now in Safari 18.0, the first browser to ship support, you can reference the currentcolor or a system color keyword as you define the new color. For example, this code will set the background color to be the same color as the text color, only 4 times lighter, as calculated in the oklch color space.

Being able to reference system color keywords opens up another world of options. System colors are like variables that represent the default colors established by the OS, browser, or user — defaults that change depending on whether the system is set to light mode, dark mode, high contrast mode, etc. For example, canvas represents the current default background color of the HTML page, while fieldtext matches the color of text inside form fields. Find the full list of system colors in CSS Color level 4 .

Relative Color Syntax lets you define dynamic connections between colors in your CSS, lessening the need to control color through variables in a tightly-regimented design system. Learn more about Relative Color Syntax by watching this portion of What’s new in CSS from WWDC23.

Translucent accent colors

Partially transparent colors in accent-color are now blended on top of the Canvas system color to match the latest updates to the web standard. This means that any of the many ways to define colors using an alpha channel will now work as expected when used to define an accent color for a form control.

Animating display

WebKit for Safari 18.0 adds support for transition animation of the display property.

Many developers are excited to use @starting-style along with transition-behavior and display: none interpolation. WebKit for Safari 17.4 added general support for transition-behavior , including transition-behavior: allow-discrete . WebKit for Safari 17.5 added support for @starting-style , letting you define starting values for transitioning an element as it’s created (or re-created). Now in WebKit for Safari 18.0, you can use these features together to transition the display property.

Backdrop Filter

Originally shipped in Safari 9.0, backdrop filter provides a way to apply graphics effects to the content behind a particular element. You can apply backdrop-filter to a headline, for example, and everything behind the headline will be blurred, or have decreased saturation, or increased contrast. Any of the filter functions from SVG can be used — blur() , brightness() , contrast() , drop-shadow() , grayscale() , hue-rotate() , invert() , opacity() , saturate() , and sepia() .

For many years, backdrop filter only worked in Safari. It was available when you prefixed the property with -webkit-backdrop-filter . Now, starting in Safari 18.0, you don’t need the prefix. We also improved our implementation, fixing bugs and boosting interoperability.

This demo shows eight different filters and what you might do with each one alone. You can, of course, combine filters to create even more interesting results. With backdrop filter supported in Safari since 2015, Edge since 2018, Chrome since 2019, Samsung Internet since 2020, and Firefox since 2022, this is a great time to consider the kind of graphic design possibilities it enables.

Content visibility

WebKit for Safari 18.0 adds support for content-visibility . This property controls whether or not an element renders its contents in a fashion that’s useful for making performance optimizations. It lets you communicate to the browser that certain portions of the page will likely be initially offscreen, and suggest they be omitted from layout and rendering. This can make the page load faster.

WebKit for Safari 18.0 adds parsing support for the custom value for the prefers-contrast media query. (It does not return “true” on Apple platforms, since there is no forced-colors mode in iOS, iPadOS, macOS or visionOS.)

Safari 18.0 for visionOS 2 adds support for immersive-vr sessions with WebXR . Now you can create fully immersive experiences for people using Apple Vision Pro and deliver them through the web. WebXR scenes are displayed using hardware-accelerated graphics driven by WebGL .

Safari for visionOS 2 supports the new WebXR transient-pointer input mode. It lets you make the most of natural input on visionOS, and allow your users to interact with a look and a pinch.

If you want to animate a 3D model of the user’s hands, Safari for visionOS 2 also includes support for WebXR hand tracking . To ensure privacy, permission to allow hand tracking will be requested from users at the start of their WebXR session.

Learn all about WebXR on visionOS 2 by watching Build immersive web experiences with WebXR from WWDC. Learn more about transient-pointer input mode by reading Introducing natural input for WebXR in Apple Vision Pro . And learn all about how to use Safari’s developer tools on Mac to inspect and debug in Apple Vision Pro by reading Try out your website in the spatial web .

Spatial photos and panoramas

One of the amazing experiences you can have on Apple Vision Pro is looking at spatial photos and panoramas. The web is a great place to share these photos with others.

When you open the Photos app in visionOS, you see your library of photos. When you tap an image, it appears alone in a floating frame in front of you. Spatial photos appear at just the right height and viewing angle to make it feel like you’ve gone back to a moment in time. A second tap of the UI breaks a spatial photo out of its frame, becoming even more immersive. Similarly, a panorama floats in a frame on first tap. Then on second tap of the UI, it expands to wrap all around you, creating a fully immersive experience.

Now in Safari 18.0 for visionOS 2, you can use the JavaScript Fullscreen API to create a similar experience on the web. You can embed the photo in a web page, and provide the ability to tap. The photo will pop into a floating frame as the Safari window disappears. Then when the user taps on the spatial photo or panorama UI that visionOS provides, the photo will further expand to create a more immersive experience. When they exit the image, the Safari window will return.

Let’s walk through how to support experiencing a spatial photo or panorama on the web using Fullscreen API. First, include the image on your web page using any of the techniques used for years. Here, we can embed a flattened panoramic photo into the web page using simple HTML.

Then using JavaScript, we’ll trigger .requestFullscreen() on tap. Perhaps like this.

You could, of course, create your own UI for the user to tap, rather than making the entire photo the tap target.

Spatial images work just the same, although it’s likely we want to provide fallbacks for browsers that do not support HEIC files . We can do so with the picture element.

Spatial images are stereoscopic, with both a left and right channel. In Safari, when the image is embedded in the web page, the browser will show the left channel. And there’s no need to worry about providing a fallback of any sort for Safari on macOS, iOS, or iPadOS — the stereoscopic HEIC file works great.

This technique will also cause images to go fullscreen in any browser that supports Fullscreen API. Learn more about adding panorama and spatial photos to your websites by watching Optimize for the spatial web from WWDC.

Shaping interaction regions on visionOS

As a web developer, you’re very familiar with how link styling works on the web. For decades you’ve been able to use CSS to style text-decoration , color and more for :link , :hover , :active , and :visited states. You’ve also been able to adjust the size of the invisible tap target through use of padding.

Apple Vision Pro adds a new dimension to how links work — tap targets are visible on visionOS. Anytime a user looks at an interactive element, it’s highlighted to let them know that it can be tapped. And you as a designer or developer can intentionally design how an interaction region looks. You may want to add padding, for instance, or even a rounded corner to the otherwise invisible box.

Now in Safari in visionOS 2 , when you use CSS clip-path to change the shape of tappable area of a link, the visible interaction region will change shape as well. Interactive UI elements built with SVG and cursor: pointer will also be highlighted with the proper shape. Learn more by watching Optimize for the spatial web from WWDC.

Video on visionOS

Safari for visionOS 2 adds support for docking fullscreen videos into the current Environment . Anytime a user is watching a video fullscreen, they can tap the mountain symbol to enter an immersive experience. Turning the Digital Crown adjusts the immersion.

Writing Suggestions

At last year’s WWDC, Apple unveiled inline predictive text on iOS, iPadOS, macOS and more. It helps users input text faster by predicting what they might be typing and finishing the word, phrase or even a whole sentence when the user taps the space bar. Now, WebKit for Safari 18.0 on iOS, iPadOS, visionOS, macOS Sequoia and macOS Sonoma brings inline predictive text to the web.

While inline predictive text makes for a fantastic, personalized user experience, there might be specific situations on the web where it’s better to not have predictions. WebKit for Safari 18.0 on iOS, iPadOS, visionOS, macOS Sequoia and macOS Sonoma gives web developers the opportunity to disable inline predictions through the writingsuggestions attribute. By default, writing suggestions is set to true. You can turn off the capability by including the writingsuggestions="false" attribute on any type of text input field.

WebKit for Safari on iOS 18 adds haptic feedback for <input type=checkbox switch> . This means, now when a user taps a switch control on iPhone, a single tap is felt — just like how toggling a switch feels in Settings app on iOS. Try this demo to see what it’s like.

Date and time inputs

WebKit for Safari 18.0 on macOS improves accessibility support for date and time input field types. Now <input type="date"> , <input type="datetime-local"> , and <input type="time"> elements work properly with VoiceOver.

Usually elements have the labels they need, but sometimes there is no text label for a particular button or UI. In this situation, ARIA can be used to provide an accessible label. The aria-label attribute provides names of labels while aria-roledescription provides the description for the role of an element.

On very rare occasions, you may need to override aria-label or aria-roledescription to provide different names or descriptions specifically for braille. The aria-braillelabel and aria-brailleroledescription attributes provide such an ability. They exist to solve very specific needs, including educational contexts where the site needs to render the specific braille table dot pattern. If you do use braille-related ARIA attributes, be sure to test them using a braille reader. If in doubt, relying on the accessible name from content or aria-label / aria-roledescription is almost always the better user experience . WebKit has supported these ARIA attributes for years.

Now, WebKit for Safari 18.0 adds support for the ariaBrailleLabel and ariaBrailleRoleDescription element reflection properties. These make it possible to get and set the aria-braillelabel and aria-brailleroledescription ARIA attributes on DOM elements directly via JavaScript APIs, rather than by using setAttribute and getAttribute .

WebKit for Safari 18.0 adds support for Unicode 15.1.0 characters in RegExp. Unicode 15.1 added 627 characters, bringing the total of characters to 149,813. Now, these new characters can be used in regular expressions.

WebKit for Safari 18.0 also adds support for the v flag with RegExp.prototype[Symbol.matchAll] . providing more powerful ways to match Unicode characters, as specified in the ECMAScript 2024 standard.

For example, you can now specify to only match on Latin characters, while avoiding matching on Cyrillic script characters.

Or split a string matching on Emojis.

WebKit for Safari 18.0 adds support for URL.parse() , a way to parse URLs which returns null rather than an exception when parsing fails.

WebKit for Safari 18.0 expands Declarative Shadow tree support by adding the shadowRootDelegatesFocus and shadowRootClonable IDL attributes to the <template> element. It also adds the shadowRootSerializable attribute and shadowRootSerializable IDL attribute to the <template> element, enabling those using Declarative Shadow roots to opt into making them serializable. Serializing can be done through the new getHTML() method that has been added at the same time.

WebKit for Safari 18.0 adds support for PopStateEvent ’s hasUAVisualTransition , indicating whether the user agent has a visual transition in place for the fragment navigation.

WebKit for Safari 18.0 adds support for subresource integrity in imported module scripts, which gives cryptographic assurances about the integrity of contents of externally-hosted module scripts.

WebKit for Safari 18.0 adds support for the bytes() method to the Request, Response , Blob , and PushMessageData objects. This replaces the need for web developers to call arrayBuffer() , which can be difficult to use, and wraps the result in a Uint8Array . Calling bytes() is now the recommended way going forward when you need to access the underlying bytes of the data these objects represent.

WebKit for Safari 18.0 adds support for feature detecting text fragments by exposing document.fragmentDirective . Note that the returned object (a FragmentDirective ) doesn’t provide any functionality, but it’s helpful if you need to know if Fragment Directives are supported by the browser.

WebKit for Safari 18.0 adds support for the willReadFrequently context attribute for the getContext() method. It indicates whether or not a lot of read-back operations are planned. It forces the use of a software accelerated 2D or offscreen canvas, instead of hardware accelerated. This can improve performance when calling getImageData() frequently.

WebKit for Safari 18.0 extends 2D canvas support for currentcolor . It can now be used inside color-mix() or Relative Color Syntax. Here currentcolor will default to the computed color property value on the canvas element.

WebKit for Safari 18.0 adds Workers support for both Managed Media Source (MMS) and Media Source Extensions ( MSE ). This can be especially helpful on complex websites that want to ensure continuous and smooth video playback even when other site activity (such as live commenting) causes a very busy main thread. You can see the performance difference in this demo .

WebKit for Safari 18.0 adds support for the WebRTC HEVC RFC 7789 RTP Payload Format. Previously, the WebRTC HEVC used generic packetization instead of RFC 7789 packetization. This payload format provides a new option for improving videoconferencing, video streaming, and delivering high-bitrate movies and TV shows.

WebKit for Safari 18.0 adds support for MediaStreamTrack processing in a dedicated worker. And it adds support for missing WebRTC stats.

WebKit for Safari 18.0 adds support for secure HTTPS for all images, video, and audio by upgrading passive subresource requests in mixed content settings. This means that if some files for a website are served using HTTPS and some are served using HTTP (known as “mixed content”), all images and media will now be auto-upgraded to HTTPS, in adherence with Mixed Content Level 2 .

WebKit for Safari 18.0 adds support for six new WebGL extensions:

• EXT_texture_mirror_clamp_to_edge
• WEBGL_render_shared_exponent
• WEBGL_stencil_texturing
• EXT_render_snorm
• OES_sample_variables
• OES_shader_multisample_interpolation

WebKit for Safari 18.0 adds support for fuzzy search code completion in the Web Inspector’s CSS source editor.

Two years ago at WWDC22, we announced support for passkeys — a groundbreaking industry-standard way to login to websites and app services. Passkeys provide people with an extremely easy user experience, while delivering a profound increase in security. To learn more, watch Meet Passkeys or read Supporting passkeys .

WebKit for Safari 18.0 adds support for three new features as we continue to improve passkeys. First, Safari 18.0 adds support for using mediation=conditional for web authentication credential creation. This allows websites to automatically upgrade existing password-based accounts to use passkeys. Learn more by watching Streamline sign-in with passkey upgrades and credential managers from WWDC.

Second, WebKit for Safari 18.0 adds support for using passkeys across related origins. This lets websites use the same passkey across a limited number of domains which share a credential backend.

And third, WebKit for Safari 18.0 adds support for the WebAuthn prf extension. It allows for retrieving a symmetric key from a passkey to use for the encryption of user data.

Safari 18.0 also adds support for Mobile Device Management of extension enabled state, private browsing state, and website access on managed devices. This means schools and businesses that manage iOS, iPadOS, or macOS devices can now include the configuration of Safari App Extensions, Content Blockers, and Web Extensions in their management.

WebKit for Safari 18.0 adds support for funds transfer via Apple Pay.

While it’s rare to deprecate older technology from the web, there are occasions when it makes sense. We’ve been busy removing -webkit prefixed properties that were never standardized, aging media formats that were never supported in other browsers, and more. This helps align browser engines, improve interoperability, and prevent compatibility problems by reducing the possibility that a website depends on something that’s not a web standard.

WebKit for Safari 18.0 removes support for OffscreenCanvasRenderingContext2D ’s commit() method.

WebKit for Safari 18.0 deprecates support for a number of rarely used -webkit prefixed CSS pseudo-classes and properties — and even one -khtml prefixed property.

• -webkit-alt and alt properties
• :-webkit-animating-full-screen-transition pseudo-class
• :-webkit-full-screen-ancestor pseudo-class
• :-webkit-full-screen-controls-hidden pseudo-class
• :-webkit-full-page-media pseudo-class
• :-webkit-full-screen-document pseudo-class
• :-khtml-drag pseudo-class

WebKit for Safari 18.0 also deprecates support for the resize: auto rule. Support for the resize property remains, just as it’s been since Safari 4. The values Safari continues to support include : none , both , horizontal , vertical , block , inline , plus the global values. Early versions of CSS Basic User Interface Module Level 3 defined auto , but it was later written out of the web standard.

WebKit for Safari 18.0 also deprecates support for non-standardize WEBKIT_KEYFRAMES_RULE and WEBKIT_KEYFRAME_RULE API in CSSRule .

WebKit for Safari 18.0 removes support for the JPEG2000 image format. Safari was the only browser to ever provide support.

If you’ve been serving JPEG2000 files using best practices, then your site is using the picture element to offer multiple file format options to every browser. Safari 18.0 will simply no longer choose JPEG2000, and instead use a file compressed in JPEG XL, AVIF, WebP, HEIC, JPG/JPEG, PNG, or Gif — choosing the file that’s best for each user. Only one image will be downloaded when you use <picture> , and the browser does all the heavy lifting.

We have noticed that some Content Deliver Networks (CDN) use User Agent sniffing to provide one file to each UA, offering only JPEG2000 images to Safari — especially on iPhone and iPad. If you expect this might be happening with your site, we recommend testing in Safari 18.0 on both macOS Sequoia and iOS or iPadOS 18. If you see problems, contact your SaaS provider or change your image delivery settings to ensure your website provides fallback images using industry best practices.

If you notice a broken site, please file an issue at webcompat.com .

WebKit for Safari 18.0 removes [[VarNames]] from the global object to reflect changes in the web standard, a change that now allows this code to work:

WebKit for Safari 18.0 removes support for non-standard VTTRegion.prototype.track .

WebKit for Safari 18.0 removes the last bits of support for AppCache.

When AppCache first appeared in 2009, in Safari 4, it held a lot of promise as a tool for caching web pages for use offline. It was imagined as “HTML5 Application Cache” back when HTML itself was being further expanded to handle more use cases for web applications. A developer could create a simple cache manifest file with a list of files to be cached. Its simplicity looked elegant, but there was no mechanism for cache busting, and that made both developing a site and evolving the site over time quite frustrating. AppCache also had security challenges. So new web standards were created to replace it. Today, developers use Service Workers and Cache Storage instead.

WebKit deprecated AppCache with a warning to the Console in Safari 11.0. Then in 2021, we removed support for AppCache from Safari 15.0, with a few exceptions for third-party users of WKWebView . Now we are removing those exceptions. This change to WebKit will only affect the rare web content loaded in older third-party apps that have JavaScript code which relies on the existence of AppCache related interfaces.

WebKit for Safari 18.0 removes the SVGAnimateColorElement interface, as well as the non-standard getTransformToElement from SVGGraphicsElement .

WebKit for Safari 18.0 removes support for four non-standard Web APIs:

• KeyboardEvent.altGraphKey
• AES-CFB support from WebCrypto
• KeyboardEvent.prototype.keyLocation
• HashChangeEvent ’s non-standard initHashChangeEvent() method

Deprecated some legacy WebKit notification names including:

• WebViewDidBeginEditingNotification
• WebViewDidChangeNotification
• WebViewDidEndEditingNotification
• WebViewDidChangeTypingStyleNotification
• WebViewDidChangeSelectionNotification

In addition to all the new features, WebKit for Safari 18.0 includes work to polish existing features.

Using Developer options

Because they are advanced settings that most customers don’t normally need or use, the Developer options are hidden by default. To access all the hidden settings, you have to turn it on. Remember, you should only use Developer mode if you are familiar with Android app development.

• First, navigate to and open Settings . Tap About phone , and then tap Software information .

• A popup message will appear when you are close to enabling the mode. If you have a lock screen set, you’ll be asked to enter your security credentials.
• The Developer options will be activated; you can now access it at the very bottom of the main Settings menu.

You can disable the Developer options and hide the menu by opening Settings , and then tapping Developer options . Tap the switch at the top of the screen to turn off Developer options.

You can also report an error through the Samsung Members app if you're having issues with your phone. Just tap Support and select Error reports under Send feedback. Follow the on-screen instructions to describe your issue and send a report.

If you're interested in developing apps for Galaxy devices, visit Android Developers and Samsung Developers for more information.
