So, my girlfriend is a graphic designer, and uses Adobe's CS4 suite daily. She upgraded to Snow Leopard, and now it takes about a minute-a-megabyte to save an image to disk. It's painful to watch, and she's going a bit insane with this. The computer is a year-old iMac.
Adobe is "looking into it", and seems to want Apple to patch this. Apple seems to want Adobe to patch this.
Is there any way to go to Leopard from Snow Leopard if Time Machine wasn't enabled when the original update was applied? Is there anyway to install the OS from scratch without losing everything else on the computer?
So, the problem seems to be documented by Adobe here, in that A bug can cause Photoshop & other applications to crash, particularly during Open and Save operations.
