How to fix contacts being read-only? My Contacts (accessible via Mail or the Contacts applications) are read-only on my Mac Book Pro running Mac OS X 10.8.2. Contacts reports itself as Version 7.1 (1167).

I have 5 total contacts currently, including Apple and "Me". Not sure what I did to add the other 3, but they cannot be modified or deleted, nor can I add any new ones.

If I add or edit a contact it behaves normally, until I close Contacts. When I reopen it then all the changes are gone.

I thought maybe the contacts folder was read-only in my Library, and thought I double checked that, but maybe I missed something.

The interesting thing is both the "On My Mac" and "iCloud" contacts are read-only.
It looks like there is, as you mention, a file permission problem, or maybe the Contacts database is corrupt.

In either case, try rebuilding the database:


Open Contacts and export your contacts with File&gt;Export...&gt;Contacts Archive....
Quit Contacts.
Open ~/Library/Application Support/ in the Finder (you will need to switch to the Finder, press Shift⌘G, type ~/Library/Application Support and press Enter).
Rename ~/Library/Application Support/AddressBook to ~/Library/Application Support/AddressBook.bak.
Start Contacts. You will notice that there are only two contacts: Apple and you. Delete them.
Import the previously exported contacts with File&gt;Import....
