A Question: Are there any problems of incompatibility between CS5.5 and OSX 10.9.5?
As soon as I open Photoshop, the screen goes black and the PowerBook Pro 15 "crashes.
Hi GianniTO,
As of now the legacy versions have not been tested on Mac Yosemite. You might face compatibility issues.
Only CC has been tested and we found no major issues. Please refer: https://helpx.adobe.com/x-productkb/global/mac-os-yosemite-compatability.html
