I'm still on Snow Leopard, as are many video and audio folks I know. "If it ain't broke..."
However I came across this
"Today, while working on an edit and getting fed up with it crashing (something I’m really not used to on a Mac) out of frustration I decided to upgrade the OS to Mountain Lion.
Wow, I wish I had done this earlier. What a difference."
Does that tally with other folks' experience here?
Mountain lion has been nearly 100% error free for me. I use the entire CS6 MC.
Not many problems for me. The biggest being that mountain lion does not recognize when I disconnect my 2nd monitor. But that isn't a cs6 issue. I use dual monitors because I do a lot of tutorials...so that should tell you that I'm no expert and my word doesn't go too far. Maybe some AE vets will chime in. But as a laymen to AE, I have no complaints.
