MacOS 10.13.4 Cannot turn off lock screen in system preferences
I guess since up 'upgraded' to 10.13.4 I get a login screen if I leave my MacBook air alone for the briefest time. This is a real pain in the neck.
In system preferences the this statement is checked:
"Require password [immediately] after sleep or screen saver begins."
I can't uncheck this box, and I can't change the [immediately] to anything else. If I could change it to 8 hrs I wouldn't be so unhappy, but as it is it is intolerable. Makes me want to go back to Linux.
I live alone and I have never taken my MacBook to any place public. I guess Apple in their wisdom thinks that if I go to the kitchen to freshen my coffee someone will bust down the door and steel all my secrets.
I would be glad to downgrade my OS if I could figure out how, and if that would actually make a difference.
I hope someone has a solution for this, I'm at wits end.
Solution 1:
I was stumped with some issues for days now, reading everything I could on the subject, and I finally found the solution: it is a keychain problem with as simple solution.
The solution is to delete one or more folders located in ~/Library/Keychains/, that is to say folders in the Keychains folder in our user Library.
The folders to be deleted have long names like: A8F5E7B8-CEC1-4479-A7DF-F23CB076C8B8.
You may have one or more folders with these long names and they can be safely deleted: one such folder will be recreated after rebooting.
Do not remove anything else contained in you Keychain folder, and reboot.
Once rebooted, reinstall all extensions in Safari, and/or enable other features you we having issues with.
Trashing those folders solves many issues such as:
Security login screen system prefs not recognizing your changes & your password (locks the screen immediately on sleep or screen saver);
Safari disabling all your extensions and not recognizing your password if you try a solution in the developer's menu;
iCloud system prefs not wanting to enable your iCloud Keychain and complaining it can't communicate with the iCloud server;
Safari not recognizing your password when you try to access the passwords tab in Safari preferences;
Login screen disregards Automatic Login settings and insists on asking for a user password.

I found this solution at TechRaptor (thanks!), although at first it seems a bit unrelated (many screen captures in article): The Iron Mac: How to Get Rid of Annoying Local Items Keychain Box.
