mac os x 10.7.5 crashes photoshop cs4

I just want to point out how very nice it is to type in an issue "photoshop cs4 crashes on startup 10.7" and get the perfect solution in about 3 seconds. I have been maintaining my office makes for about 22 years. I remember spending days trying to get to the bottom of issues... calling software companies then Apple and each blaming the other or me for the issue. Trust me...These are the good old days! Thanks!!!

Thank you, Dennis. Though I'm still using Suitcase 12.1.7 (haven't got around to updating; it's way too expensive) I did download the trial of Fusion 4 so the plug-in is still in the Photoshop folder. I appreciate your help. Now I can upgrade Lion. I'm puzzled as to why the plug-in is still there,, though. I would have expectred AppTrap to get rid of it when I threw out the expired trial. Next time something crashes on me I'll look at the crash report. Trouble is, my eyes tend to glaze the moment I start reading what looks like gobbledygook. :-)

Sorry, Dennis. I wasn't very clear. I meant upgrading to Lion 10.7.5 not upgrading to Mountain Lion. I am definitely not ready for Mountain Lion yet. I upgraded to Lion only because I needed some software that didn't work in Snow Leopard.

I originally bought Suitcase because it enabled me to use a particular Postscript Font that was incomplete. I don't know how it lost its mate; I was sure I'd backed up all the typefaces. Suitcase was cheaper at the time than rebuying. It isn't any more; I could get the typeface in open face version if I wanted to for a lot less than the price of Suitcase Fusion 4.

I'm surprised Suitcase 12 still works for me, to be honest. It doesn't have a plugin for Photoshop CS4. But having thrown out the plugin you said was the problem, I then activated this font and opened Photoshop to see if I could use it Yes I could. I then quit Suitcase and tried again, but the font wasn't available. So Suitcase 12 must still work in Photoshop CS4 despite the lack of a plugin. I'm puzzled! Must be missing something somewhere.

Hi I am having the same problem, trying to open Photoshop CS4 on iMac running OS X Lion 10.7.5 - but I don't use Extensis. Any ideas how I can combat this crash before opening issue? Many thanks

Hi Dennis,

Maybe you know this one. Now that I have Photoshop CS4 working fine, an old problem popped up which I had fixed in 10.7.4, through these forums, but I cannot find the instructions. When I go to move layers it crashes Photoshop. I just lost an hour's work.There was an easy fix, either a key command or a preference but apparently undid itself when I went from 10.7.4 to 7.5. Do you know what that is? Adobe has nothing useful on this matter, just a bunch of griping. I know itr is archived here somewhere.

Thanks, DEE

Never mind... I found it in this discussion

The fix is to unclick 'automatic graphics switching" in System prefs Energy Saver. WOW!
