Hi! Before I start, I want to let you know I already tried repairing permissions, chmod -R 1777, setting permissions manually in Get Info, and resetting Home permissions via OnyX and User Accounts. I had a recent data mishap, and the backups I had made turned out to be weird so I had to manually copy /Users/ back into the root directory after a fresh install of ML. Ever since, I've been having permission issues. As of now, all but one remains fixed. I can't seem to do some things related to iTunes accounts, including but not limited to: linking my user account to iTunes; downloading purchased content from the Store; registering the new install; and some other things. It doesn't give a clear error message, but instead with the included screenshot. or some variant thereof. I've repaired permissions multiple times and double checked iTunes has read/write capabilities to the iTunes folder, yet the issue persists. Does anyone have a clue as to what the problem might be?
