macOS Browser Tests on Apple Silicon
Sauce Labs now supports macOS 27 Golden Gate on Apple Silicon-powered Macs. These environments offer improved performance, modern architecture alignment, and compatibility with ARM versions of the major browsers. This enables you to test web apps on Safari 27 as well as Chrome, Firefox, and Edge.
macOS 14, 15, 26, and 27 are available to customers with the required subscription. If you don't have access, contact your account manager to discuss upgrading.

Known Limitations
The following limitations apply to macOS 27 Golden Gate:
- Beta and Dev channel browser builds are not yet available. Use the stable browser versions listed above.
- The Playwright, Cypress, and TestCafe runners do not yet support macOS 27. Use macOS 14, 15, or 26 for those frameworks.
Test Capabilities
Tests on macOS 14 and newer can include the armRequired parameter passed with "true" in the Sauce Options to ensure they are routed to the correct architecture. Prior to March 15, 2026, armRequired was required for tests to run on ARM machines; it is now optional when targeting specific versions and can be excluded for future test runs. If you're using Platform variables like current_major, continue to include armRequired to receive macOS 14 and above.
{
sauceOptions.put("armRequired", true);
browserOptions.setCapability("sauce:options", sauceOptions);
}
