Totally Rad on Mac

I am possibly buying a mac, but currently have a pc. I have totally rad actions on my pc, and is it possible to load them on a mac w/out having to buy them again? It is an .atn file, and from what I could gather, it can be used for both PC and MAC. Just wondering if anyone bought the actions and have used them for both different systems?
Thanks!

Can't see why it wouldn't run on a Mac. It's a relatively simple Javascript routine and some folders.

I don't see why not according to their website the license allows you to run them on 4 systems in a business or studio and the system requirements make no mention to a particular platform only that it needs to be running CS2 or newer. So I say go for it and welcome to the wonderful world of Mac and OSX

another question....as stated before, I have a pc and I have both vista and window's 7 on that one pc. my photoshop cs4 and lightroom program is running on vista, but I want it to run on window's 7 as well. when I try to load it up through that drive that its installed on while I am in window's 7, it won't work. So do I need to reinstall it while in window's 7?

But here is the important question at hand, I know that you can install photoshop on 2 different computers.....and we want to install it on a 2nd computer that we have as well. But if I reinstall photoshop on window's 7, does that take up that "2nd computer" install, which in turn, won't allow me to install it on our 2nd computer?

I hope that made sense......lol....i'm living on no sleep and that is the best way that I could explain it at the moment.
