I'm not working with mac so i was wondering is there a way for mac users to read a PSD files that was made in Windows OS?Beacuse i'm finishing my PSD design and i don't know how will my clients open it in Mac ? :s
As far as I know, everything you create within any Adobe product supports Mac natively. In fact, Adobe first released all their products for the Mac OS.
In short, you shouldn't worry about any of that. Your .PSD files will be cross-compatible.
