I am currently running Adobe CS 1.x on my Apple G5 with OSX 10.2.8. I would like to upgrade my OSX version. I am not sure if I have CS 1.0 or 1.3. Could you please answer this question for both possibilities? Q: What is the highest OSX version that I could upgrade to without rendering my version of the Adobe software incompatible? Please include any incremental versions such as 10.3.xx in your answer if applicable. Thank you very much for your help.
