I just got my Mac back from the shop. I left my login password with them so they could go in, fix it, and do what they have to do. Now that I have it back, the following things have changed: - My account, started by me protected by that password, now AUTOMATICALLY logs in at startup. - They created a new account, known as 'Other...' - The login password, which I've always used, no longer works when I need to unlock settings changes. What should I do?
