I work with an Apple laptop retina display with OS 10.9.4
I have an InDesign CC 2014 document and I can't save changes. I tried exporting as .idml opening that and saving as .indd. Doesn't work: nothing gets saved. I've replaced the preferences, that didn't do any good either. I have reinstalled InDesign CC 2014: nothing. I restarted my computer: no luck. When I open the same document on another computer it does O.K. Other InDesign documents are O.K. as well. What is going on?
It sounds like you might be having some permissions issue on your computer, or there might be permission restrictions associated with the file you are working on.
Always make sure that you have made a proper back-up before running system checks and fixes.
Fingers crossed this will resolve the issue.
I'd already made a new User Account and for the time being that solved my problem. After receiving your suggestion I tried the Disk Utility.app (and repeated it several times) and it fixed the InDesign document (or rather the User Account on my Apple). Anyway: thank you for your help!
