Can not install guardian browser

The Studio Display isn’t the Mac itself, so the part that matters is which Mac you have and which macOS version it’s running.

If you mean the ProctorU Guardian Browser, there are separate Mac downloads for Apple silicon and Intel Macs. Choosing the wrong one can cause a compatibility message.

On the Mac, choose Apple menu > About This Mac and check whether it shows an Apple chip or an Intel processor. Then download the matching Mac version of Guardian.

If you post your Mac model and macOS version, that would help narrow it down.

What Mac model do you have exactly?

What macOS version is it running?

What download are you choosing from the Guardian website?

Please provide some details and context and we may be able to advise.
