It is running ridiculously slow. Every time i click or press a key on the keyboard it freezes for about 5 seconds. I am on a Mac Pro running OSX 10.11.6 (El Capitan). I tried the "fix" that was suggested for someone else, but changing the preferences under advanced type did not work for me. below is a screen shot of my preferences. I use this program daily. Is there a way to roll it back to CC 2015? [EDIT]: I deleted my preferences. That did not help either.
Have you run Disk Utility to repair permissions lately?
