In system preferences, under Security and Privacy, the "Require Password" box is not checked. Interestingly, even when I have entered my password and the lock icon is open, I cannot check this box - I click on it, and the checkmark briefly appears and then goes away.

Despite the box not being checked, my computer almost always makes me type in a password when I open it or after it goes into the screen saver.

Occasionally, it does unlock automatically, but when it does so, I cannot click or interact with any windows, and I have to shut and open my screen again and type the password in order to actually use my computer.

I am using a MacBook Air running macOS High Sierra.

  • Lets be clear do you mean it always LOCKS or does it indeed log you out? EG quit out of all open applications and any background apps you have run automatically, and then prompt to log in? Your question seems to conflate the two. – Steve Chambers May 12 '18 at 23:44
  • Does your MBA go to sleep during the period of inactivity (when the lid is closed)? – Allan May 12 '18 at 23:54
  • @SteveChambers It locks. I have clarified the question. – Johnny Dollard May 13 '18 at 1:26
  • @Allan I'm not sure how to tell if it's sleeping or not, but I think so? Essentially, it is behaving as if I have "Require Password [immediately] after sleep or screen saver begins" checked, even though it is not checked. – Johnny Dollard May 13 '18 at 1:28
  • See this Apple support document. When you close your lid, you put it to sleep. The password setting is for the screen saver. – Allan May 13 '18 at 4:48

If you close your laptop then immediately reopen it does it lock itself? also in the settings it specifies that it will not lock after "sleep or screen saver begins." Which means what may be happening is that your MacBook is passed a sleep state and has entered standby mode and locked itself.

Side Note: Why would you want your mac not to lock itself. Closing the lid does not protect against potential attackers if you have this setting disabled. It also makes it harder to lock you computer when you want to.

  • Yes, it locks immediately. As I stated, I am unable to select the option to require a password (although it requires one anyway). Besides, I use my computer mostly at home and only my family has access to it, I am not particularly concerned about security. – Johnny Dollard May 13 '18 at 2:16
  • @TrumpetDude i have a new idea it could be related to keychain and having to unlock that – nicco swanson May 13 '18 at 2:29
  • I have also had issues with the keychain, with my computer repeatedly asking me to enter the keychain password sometimes when I wake it up. However, this only happens when I actually log in, not when I type in the password to wake it up. – Johnny Dollard May 13 '18 at 14:03
