Mac OS X v10.9 is not one of the supported operating systems for After Effects CS5:
It's too bad because all of my other CS5 programs work fine on maverick. Follow-up question . I just downloaded the CC After FX trial and now I get an error message :
After Effects warning: Could not rename the file '/Users/jazjoylee/Library/Preferences/Adobe/After Effects/12.2/Workspaces.1535.1407351444160161.xml' to 'Workspaces.xml
I can't win. Must I deinstall After FX CS5 in order to run the CC trial?
Thank you for your help
