Comment CS is multi-platform software. (Score 1) 128
Yes, certain elements are kind of a pain in the ass on the Mac. But the Mac hasn't been the best platform to run CS apps on in years. Windows is. Hell, Photoshop runs better in Windows than it does in OS X *on identical hardware.*
Since the 90s, to maintain an Apple product, Adobe has had to: Port from 68k to PPC, then from Classic MacOS to OS X (Photoshop 7 SUCKED on the Mac, but it ran in both operating systems), then they had to adapt from OS X PPC to OS X Intel. Apple jerks their developers around constantly, while Windows just isn't the same kind of moving target.
While I'm sure you'd love it if Adobe conformed completely to Apple guidelines and played nicely with comparatively recent (I know 10.7 is "old" but the move to Intel is older than that) features that have no Windows equivalent, keep in mind that the more hassle the Apple market is to develop for, the less likely they are to develop for it. Remember when they stopped releasing Premiere for the Mac for awhile because it couldn't compete with Final Cut Pro?
I still use Photoshop on a Mac but only occasionally - I've moved my entire toolchain to Windows, and while it sucks in some ways the Mac experience doesn't I've gotten used to it. I'm looking at expanding my line art production software, as there's a few options in that space, but for graphical heavy lift Adobe has effectively cornered the market.
Importantly, I've been using it since 1997 - any alternative has to be featureful and intuitive, and it's competing with 20+ years of muscle memory and needs to be able to correctly read ~15 years of files.
