I'm not a frequent indesign user, but it is very annoying... I am not able to indesign at the moment.
As soon as i start indesign, and everything is loaded it just freezes. Tried a reinstall a few time. But no luck.
I'm using the newest CC 2015 (august) on OSX El Captian.
Also i tried installing Indesign CC2014 and CS6, but creative cloud just hangs at "waiting" when I click on install.
Another thing is that Clean My Mac say's "CEPHtmlEngine Helper" is freezing. Not certain if that is related....
Hoping for a VERY quick response....
Untick "Automatically hide and show menu bar" in El Capitan System Preferences under the General Tab
But that option was already unticked... It is still not working
Try upgrading to CC2015.2
