I went ahead and upgrade to OS X Yosemite and I wish I hadn't. A number of things are acting weird--especially with Photoshop. Mainly two things.
First one is Command-Z doesn't redo half of the time. I've never had this issue in 15 years and it just started happening with Yosemite early last week.
The other thing is when I'm sliding the bar to strengthen/weaken the brush or erase tool, it often won't acknowledge that I've clicked off of the slider and it will keep sliding as my brush moves around. If I tap the pen again it will click out--but often that tap will create a paint mark on my art.
Irksome as hell. Anyone else experience these problems? At first I thought it had something to do with my Wacom pen being too sensitive or not sensitive enough. I assumed installing Yosemite just threw my settings all whack, but I checked and everything looked fine.
Any suggestions or input would be much appreciated. Thanks very, very much for taking the time to read this.
I'd be acting wonky myself if I had been hit by Yosemite!
Happily running CS6 13.0.6 under Lion 10.7.5.

LesToil: You need to re-install Photoshop. There have been a ton of people complaining that Yosemite corrupts the previous installation of Photoshop.
