It's been almost impossible for me to take proctored test lately since I have a Mac

You could possibly use BootCamp to create a small Windows install to just to use for test taking.

Edit: Nevermind, I see that they don't support "Windows OS on MAC". Can't really think of any reason why not, though.

I think that specifically refers to using virtual machines. They don't allow any virtual machines at all. If you're using BootCamp to actually boot into Windows rather than running it in a process, then I'd expect it would be fine. There is no difference between that and running any other hardware under Windows at that point.
