Can't save files in my own directory due to insane permission error I was working on my mac and saved a file. Continued to work on the file. One hour later, when I tried to save that file, I saw the message "The document could not be saved. You don't have permission". What??? Now I see I cannot save any of my files. I can open them, but I cannot save. Any file. But this is selective. TextEdit can save the files, Mail.app can open emails and save attachments. Xcode can create and save new projects, but I cannot modify them, or I will see the error if I try to save.

This is what I have tried to do:


chown, chmod -R 755, etc. on the directory containing my projects doesn't help.
Disk Utility > Repair Permissions doesn't help.
Reinstalling the app, clearing their .plists, etc. doesn't help.
I can create a new project or document with these apps (Xcode and Photoshop for example, just to name a few) and it saves the file on my documents directory, but if I change the document and try to save, I see the error.
I have rebooted the computer and also turned it off and on.
I did a safe mode boot and scanned the disk using /sbin/fsck -fy and no issues were found.
I have deleted all caches and application support files.
I did a chmod -R -N ~ on my documents directory, suspecting that some ACLs could be the guilty. No change.
I did a recursive chown to take ownership of my own files. The ownership was correct before, but I just did it again to clean anything that could be wrong.
I reinstalled both apps and nothing.


What more I can? Cry?

Thoughts? Thanks
I had the same problem.  I tried what Matt Love has suggested and still had the problems.  I then downloaded Cocktail and ran permission repair, rebooted and all worked again.
