Permissions suddenly a problem

I'd operate under the assumption that something weird happened to your user permissions (with the caveat that there are other things that can mimic that problem, especially if an application gives bogus error messages).

In which case:

Simpler option: Open your /Users/ folder, get info on your user folder, and check that the permissions there have sense (owned by you, read-write for you, and read-only or no access for your group and Everyone). Then unlock with the little icon and select Apply To Enclosed Items... from the gear menu, which should completely reset your home folder, although it might screw up the Dropbox and Shared folders a bit. There are also terminal commands for doing this and removing errant ACLs, but that's a start.


More thorough option: Use the Password Reset utility to reset the permissions on your home folder. Used to be on the OS install disc, now accessed through the Recovery partition; the second post here explains the problem:

...that should completely fix any weird permissions/ACLs in your home folder, and has worked for me when in the past when doing weird manual migrations that didn't set permissions right.


I'd do the latter, personally, to start with, and see if that works.
