To run Safari on macOS, some manual setup is required:

• Allow Safari to be controlled by SafariDriver: safaridriver --enable

• Allow pop-up windows: defaults write com.apple.Safari WebKitJavaScriptCanOpenWindowsAutomatically 1

• Trust the certificate: security add-trusted-cert -k "$(security default-keychain | cut -d\" -f2)" tools/certs/cacert.pem

• Set OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES in your environment. This is a workaround for a known macOS High Sierra issue.

Now, run the tests using the safari product:

./wpt run safari [test_list]

This will use the safaridriver found on the path, which will be stable Safari. To run Safari Technology Preview instead, use the --webdriver-binary argument:

./wpt run --webdriver-binary "/Applications/Safari Technology Preview.app/Contents/MacOS/safaridriver" safari [test_list]
