PS 2014 SLOW on Mac Yosemite 10.10

Question

I have  a real problem with many CC applications.  They are VERY slow on my Mac. I realize it is near EOL  but Dreamweaver runs acceptably. Pshop is terribly slow.  Most other CC programs are like molasses IF they run at all  (Illustrator only crashes on open).  I have 64 bit capability.   At this point, I'm going to have to go back to CS6 Suite for most things, unless there is a viable solution.

Hi
could you try to start the mac in the safe mode and then try to launch the application and check whether, they are running slow there or not.
Start up in Safe Mode (Only essential OS X items are started; some features and apps might not work correctly.) Immediately after you hear the startup tone, hold down the Shift key. Release the Shift key when you see the progress indicator (looks like a spinning gear).
