well, that takes care of that!
it doesn't run on mac without the add-on windows supplement, which i never got because at the time it cost more than the EQ does now. so to have this tool, i would have to be prepared to spend at least $450, probably more, for the EQ + the windows supplement for the mac. i don't think it's really worth it for me.
thanks everyone for answering all my questions. who knows what the future will bring, right? i may add another computer someday, downstairs where my workroom is, and that would be windows.
