Screen Resolution on macOS

There are situations where you may want to increase (or decrease) the screen resolution within the macOS VM's for testing purposes.

This can be done directly in the job with a run step, like the following:

-run: /Library/Application\ Support/VMware\ Tools/vmware-resolutionSet 1920 1080

The above would set the resolution to 1920x1080 -- which is the current maximum screen resolution. Similarly, if you require a different resolution you can adjust the values in the above command.

Additional Notes:

• This is currently only supported on the Intel macOS resource classes and is not supported on the M1 execution environments - Please place a vote on this feature request if you wish to see this feature when using Apple Silicon executors as the only available resolution on M1 VMs is 1280x720
