I recently had this issue occur with Illustrator, too, which leads me to believe this is a common problem. Unfortunately I can't remember the solve that the support chat provided!
Anyway — when I try to open InDesign on my Mac, it times out and I have to force quit. I don't even get the dialogue window that it typically shows as it loads...the icon just bounces and doesn't stop until I force quit. It's driving me crazy! I have some work I need to do and Adobe support isn't available right now.
I've got the most up-to-date version installed, logged in and out of CC, and restarted my computer. No dice. Please help!
