I believe CS6 will run on your system, but it's really a dead end. Can you finish your project in 30 days? If you can you can download a trial version instead of spending a lot of money for outdated software to run on an outdated system.
Thank you for your quick response. I am updating my Macbook Air to Yosemite now. Will I be able to use the 30 day free trial with Version 10.9.9?
Yo should be able to run the new versions on 10.9.
