I am running InDesign CC 9.2.1 and am having this same problem - Save, Save As, Check In, Revert and Save a Copy are all not available. I tried to update to the CC that came out last week, but got the message that my OS is not recognized - I am running 10.6.8 and the system requirement is 10.7. Do you have any recommendations? My Apple Software Updates says there are no updates available. I am on a MacBook Pro 6,2, bought in 2011.
Thanks for your help.
