Can i swap photoshop from windows to mac if i pre paid the annual plan and upgrade from a windows pc to a mac?
Yes, Creative Cloud is flexible that way. No "swap" is necessary. You can activate on two computers and they can be OS X, Windows, or both. So you will certainly be able to install and activate on a Mac on your current plan, even if you are still activated on your PC.
Awesome, Thanks for the quick answer!!
