Removing “Other User” from startup screen How do I get rid of "other user". I had used a Mac Tech prior and he worked on my Mac. It only showed my icon on the start up screen. Now I have another icon for another user which when I open it, it opens up a dark gray screen for what I believe is for screen sharing. 

I would like to remove it and bring it back to just one user for the start up. Thanks
I assume you're using a recent version of MacOS X.

In System Preferences, you need the Users &amp; Groups panel.  Click the padlock to allow making changes.  You can then select the unwanted user account(s) and delete them from the list.

There's also a Guest User account.  To disable this, select it in the list of users, then untick "Allow guests to log in to this computer".
