The Safari 10.1 browser version is only available in Sauce Labs on Mac OS 10.12 for automated and manual tests. Use our Platform Configurator to obtain the correct desired capabilities for your automated tests.
Note: If you only specify "10" as your browser version instead of "10.1", Sauce Labs will automatically default to providing Safari version "10.1" with Mac OS 10.12. For example, sending in the these desired capabilities will default them to Safari 10.1:
DesiredCapabilities caps = DesiredCapabilities.safari();
