Just updated an early 2009 24" iMac 2.66 core 2 duo with 4 GB ram to mavericks 10.9. Have CS5 Design Standard. Photoshop and Illustrator will run but not InDesign. Uninstalled CS5, reinstalled from disk, updated JAVA to 7. Still no luck with InDesign. Sent error report to Apple.
Updated CS5 install on new MackBook Air and all apps work. Any insight would be helpful.
