Remove the User Name from the Menu Bar in OS X Lion
On some fresh OS X Lion installations, you’ll find the user name or login appears in the upper right corner of the menu bar, even if there is only one user account on the Mac. This is actually a feature called Fast User Switching, and the name likely appears in the menu bar due to the Guest Login ability (which can be disabled separately), but if are only looking to remove the name from the menu bar here is how:
- Open “System Preferences” from the Apple menu
- Click on “Users & Groups”
- Click on the Lock icon in the lower corner and enter the admin password
- Click on “Login Options”
- Uncheck the box next to “Show fast user switching menu as:”
- Close out of System Preferences
Alternatively, pulling down the contextual menu next to “Show fast user switching menu” gives you the option to reduce the name to either just the short name or to a simple icon.
Unchecking the box makes the name disappear from the menu bar immediately. This does not impact the ability to login with other users on the account though.
As to why this doesn’t show up on all Mac OS X Lion machines, it’s likely to be enabled on fresh Lion installations or re-installations, and not upgrades from Snow Leopard.
Update: Apparently you can also remove the user name from the menu bar by holding down the command key and dragging it out of the menu, much like any other menu item. Thanks to @martin for that tip.
