Photoshop CS6 and Mountain Lion

Question

I have 2011 Macbook pro with Mtn Lion. Put on PS CS6 and have pixelation and freezing, and I have to force quit.  Also cannot see all my 3rd Party plugins. I contacted Adobe (not easy) and they said problems are all due to plugins and thats all they say.  No trouble shooting...no nothing. (Plugin manufacturer won't help me either). Apple can't help.  I have $3000 computer that is useless.
1.  Do I sell computer or wait hoping Apple or Adobe will get this together?
2. Other choice is install WIndows 7 on boot camp and run Paint Shop Pro.  However I doubt any of the old plugins will work on the 64 bit.  What if I install 32 bit WIndows 7? Will old plugins work?
I need help, this is frustrating to no end.

Answer 1

It seems to me that many of the 3rd party plugins are older and I suppose they are 32 bit.
Easiest way to tell is to check your filters list. If you know the filters are installed correctly (in Photoshop's Plug-ins folder) and they don't show up in the list while running PS, they're 32 bit, or possibly even 16 bit depending on how old they are.
So I cannot use either PS program successfully. Is there no fix even for  PS4?
I presume you mean PS CS4 and not literally version 4? Adobe officially supports CS6 and CS5.5 in Mountain Lion. CS4 is Intel native as a Universal app, but I haven't tried it in ML, so don't know how well it works.
Regarding reinstalling Mtn Lion, I could try that but the problem only occurs in Photoshop so do you think that could be the cause?
Hard to say. As an example, I tried installing the CS5, CS5.5 and CS6 Master Collections in Snow Leopard and Mountain Lion. I did this in all combinations, erasing the test drive each time so there were no leftovers from other installs. Each install had all updates installed. In each case, desktop icons were broken such that not all files saved from PS would produce an icon. Two other much larger problems is that saving files would at times either give the error that I didn't have permission to save a file, or it would say .afpdeleted could not be save. In either case, the file being saved would be deleted! You had to do a Save As again immediately before closing the image in PS to save it.
The point of this is that reinstalling the OS after installing the Adobe software fixed all of these issues every single time. So while it may seem illogical, reinstalling the OS might fix the problem.
