so didn't get to do the only thing I haven't tried (If using Mac OS X 10.10 (Yosemite), it is recommended that you enable the Reduce Transparency preference in the Display section of the Accessibility panel in Mac OS X's System Preferences) but this saturday the app kept crashing, I was thinking about bringing my OS back to something older. I was running smooth on Yosemite but I need to have something more current for Adobe CC reasons. What OS would you recommend?
