How can I turn off the logging in procedure?
A few days ago an Apple associate at the Apple store in Oak Brook, IL, added a new user to try to fix a problem I was having. Since then, even though I removed that second user, I have to log in. I am the only user so this is entirely unnecessary and I would like to go back to an automatic log in. However, I tried to change this in Apple Preferences but under Login Options the Automatic Login drop down is set for Off and cannot be changed. How do I get back to the automatic log in I had?
iMac, OS X Yosemite (10.10)
