macOS Browser Tests on Apple Silicon
Sauce Labs now supports macOS 26 Tahoe 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 26 as well as Chrome, Firefox, and Edge.
macOS 14, 15, and 26 are only available to Enterprise customers with the appropriate Premium plan. Contact your account manager to discuss upgrading.

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);
}
See the Platform Configurator for full example configurations
