Macbook Air - Late 2010 OSX 10.7.3 I've been having a login issue for over a year now. I've been searching forums & sites trying to find someone who has had a similar issue or an article that might have a way to fix this problem. The Problem: When I turn on my Mac from a being in completely shutdown state, I get a list of users that can use my computer. It lists my girlfriends account(admin) & the guest account. My account(admin) is not listed. When I log into my girlfriends account & log back out, I get the login screen that has you type in your username & password. This is the only way for me to login to my account on this computer. My account was the first account on this computer & I later added my girlfriends account. In the login settings, on both my girlfriends account & my account, the setup is that the login screen is suppose to ask for both the username & password, NOT show a list users, which it does when you first turn on the computer. Also, the guest account has been disabled in the login settings, from both accounts! It should not be showing up in the list of users when the computer is first turned on! I've run Diskwarrior, Onyx, & Disk Utility but nothing seems to get fixed. This problem has been with me since 10.7.1, I now use 10.7.3. Not amount of upgrading seems to fix the issue.
