Online macOS Browser Testing

Browserling offers free online cross-browser testing on macOS for web development and testing purposes. We run macOS 26 (Tahoe), macOS 15 (Sequoia), macOS 14 (Sonoma), macOS 13 (Ventura), macOS 12 (Monterey) on our Mac Mini servers, allowing developers to test websites and web applications in real macOS desktop browsers. Browserling can also be used as part of automated testing and CI/CD workflows to validate website behavior on macOS browsers during development.

The browsers on macOS include native Safari, Chrome, Firefox, Opera, Edge, Tor, Brave, and Vivaldi. All browsers are available in multiple versions to support testing across browser updates. For example, Safari has the five latest versions – 26, 18, 17, 16, 15. Chrome and Edge have all latest versions starting from 120. Firefox has all versions from 113.

Online macOS Browser Use Cases

Browserling is designed to support common web development and testing workflows that require access to real macOS browsers. Below are typical use cases where developers rely on macOS browser testing.

  • Cross-browser compatibility testing. Developers use Browserling to check that websites and web applications work the same across different macOS browser versions. This includes checking layout, fonts, scrolling behavior, JavaScript execution, and browser-specific features. This is especially important for Safari, which can behave differently from other browsers.
  • Safari-specific testing. Safari on macOS uses the WebKit engine and often shows bugs that do not appear in other browsers. Browserling lets developers test sites in the native Safari versions that come with each macOS release so Safari-only issues can be found and fixed early.
  • CI/CD and automated testing workflows. Browserling can be integrated into automated testing and CI/CD workflows via Live API or Headless API (coming soon). CI/CD allows validating website behavior on macOS browsers during development and developers commonly use it for automated unit tests, smoke tests, regression tests, and other browser checks as part of build and release pipelines.
  • Responsive and layout testing. Developers use Browserling to see how their site looks at different screen sizes on macOS browsers. You can resize the browser window or choose common screen resolutions to make sure layouts work well on laptops, desktops, and large monitors.
  • Security-related browser testing. Browserling is often used to test security-sensitive behavior in browsers, such as login flows, cookies, storage, headers, and browser privacy features. This helps confirm that a site behaves correctly under real browser security rules.
  • Debugging macOS-specific issues. When a bug only shows up on macOS or in Safari, Browserling helps developers reproduce and debug the problem using remote macOS browsers. Built-in developer tools make it easy to inspect and troubleshoot issues.

Online macOS Testing FAQ

What is cross-browser testing on macOS?

Cross-browser testing on macOS means checking how a website or web application behaves across different browser versions running on macOS. This includes verifying layout, fonts, JavaScript behavior, media playback, scrolling, and browser-specific features, especially in Safari, which can behave differently from other browsers.

Why should I test on macOS?

macOS handles fonts, scrolling, and graphics differently from Windows and Linux. Safari also uses a different browser engine than most other browsers. Testing on macOS helps make sure your site works correctly for Mac users.

Can I test Safari on macOS?

Yes. Browserling lets you test websites in the native Safari versions that come with each macOS release. This is useful because Safari often shows bugs that do not appear in other browsers.

Which Safari versions do you have?

We provide the native Safari versions that ship with each supported macOS release. This includes Safari 18 on macOS 15 (Sequoia), Safari 17 on macOS 14 (Sonoma), Safari 16 on macOS 13 (Ventura), and Safari 15 on macOS 12 (Monterey). Each Safari version matches the macOS version it runs on, which is important because Safari is closely tied to the operating system.

Which Mac systems do you run?

We run the most recent macOS versions on real Mac Mini servers. This includes macOS 26 (Tahoe), macOS 15 (Sequoia), macOS 14 (Sonoma), macOS 13 (Ventura), and macOS 12 (Monterey). Each macOS version is provided as a real system for browser testing, not an emulator or simulator.

Why is there a jump between macOS 15 and macOS 26?

Apple changed how macOS versions are numbered. The jump from macOS 15 to macOS 26 is a naming change, not a gap in releases. macOS continues to follow the normal yearly update cycle, with regular updates and improvements.

Can Browserling be used in macOS CI/CD workflows?

Yes. Browserling can be used in automated testing and CI/CD workflows via Live API or Headless API (coming soon). Developers often use it to run browser checks as part of builds and releases, such as unit tests and regression tests on macOS browsers.

Does Browserling support automated macOS tests?

Yes, currently you can run browser tests using the Live API. This makes it easier to include macOS browser testing in automated workflows.

Can I run unit tests in macOS browsers?

Yes. For browser-based unit tests, you can run JavaScript unit tests and front-end test suites directly in real macOS browsers. Browserling is not meant for testing native macOS applications.

Can I test responsive layouts on macOS?

Yes. You can resize the browser window or choose common screen resolutions via "Display settings" menu to see how your site adapts. This helps check layouts on laptops, desktops, and large screens.

Can I test mobile layouts on macOS browsers?

Yes. Browser developer tools can be used to simulate mobile and tablet screen sizes. This is useful for responsive testing.

Can I use Browserling for security testing?

Yes. Browserling can be used to test security-related browser behavior, such as login flows, cookies, local storage, headers, and browser privacy features. It is meant for testing your own websites during development.

Do you support JavaScript debugging on macOS browsers?

Yes. All macOS browsers include built-in developer tools. You can open the console by pressing F12, inspect elements, debug JavaScript, and view network requests just like on a local machine.

Can I test cookies, local storage, and session storage?

Yes. Browserling allows full access to browser storage features. You can test cookies, local storage, session storage, and other client-side data behavior on macOS browsers.

Can I test HTTPS, certificates, and mixed content?

Yes. You can load HTTPS sites, test certificates, and check how browsers handle mixed content warnings. This is useful for debugging security and deployment issues.

Does Browserling support WebSockets and real-time feature testing?

Yes. macOS browsers on Browserling support WebSockets and other real-time web features. You can test live updates, streaming data, and interactive applications.

Can I reproduce older browser bugs on macOS?

Yes. Browserling provides access to multiple browser versions. This makes it possible to reproduce older bugs, confirm fixes, and test how behavior changes between browser updates.

Does Browserling support penetration testing?

No. Browserling is not designed for hacking, exploitation, or offensive security testing. It is meant for functional, compatibility, and security-related testing during web development.

Can I test different browser versions on macOS?

Yes. Browserling provides access to multiple browser versions. This helps with regression testing and reproducing bugs. Safari is provided in the native version that ships with each macOS release.

Is Browserling a general macOS desktop?

No. Browserling is focused on browser testing only. It is not meant for general macOS use or running native applications.
