Thanks so much for chiming in. I checked all the fonts using Fontbook and they all check out alright. I don't know how to check video cards and drivers. I also don't know what you mean by "something I brought over from my other system". I'm using a new install of CS5 on a new MAC.
Also, can you tell me where to find the crash reports on a MAC? I'd love to find it and provide it if so. Thanks so much!
Font checkers may not detect a problem. They can tell if there is an error in the font, but can not tell if there is a conflict with photoshop.
The savest bet is to disable the directory with all the 3rd party fonts, and it you get no crash then add back in 1/2 and test, then add in another protion etc.
Not a Mac guy but you should have info in your help file to tell you how to access it. It is a very long report, and techinical.
Look for something that keeps repreating, like a program or font. If no luck post and someone here will should be able to interpret where the error is.
With a Mac the drivers should be up to date if you have the latest versoin of the OS.
The TWAIN driver can somethimes be a problem and should also be disabled. THere is no TWAIN drive for 64 bit programs.
