We use Macs and PCs. If you try to open one of my mac adobe files on the pc, it says it can't open this version. Aren't both CC programs the same version, just different operating systems? What's the point in having it for both platforms if the files aren't interchangeable? I know I can export the mac files to idml but it's a pain in the behind to have to do that every time just to be able to work on the file on both systems.
