Thanks for looking this up.
Would you mind adjusting the test_darwin_installer() test to match, the error was:

>           raise AssertionError(_error_message()) from cause
E           AssertionError: expected call not found.
E           Expected: check_output(['brew', 'install', '[email protected]'])
E           Actual: check_output(['brew', 'install', 'openssl@3'])

Also do you know why some integration tests are failing?
