Sharing & Permissions changed, and now lock screen includes a guest account and computer restarts on log-out

[laskarid]

Hi all,

Long time Windows user here and completely lost with an matter that came up in Mojave 10.14.6. I had some issues with a couple of programmes not recognizing the camera and microphone, and I followed what now seems to be bad advice, namely the post halfway down this page by loadbox. It didn't fix my issue, which I solved through another way, but it did create a new one. Now when I leave my MacBook for a time, it reverts to the lock screen (as it always did) but a guest account has now appeared and the computer frequently restarts on log-out. Is there any way I can revert back to the way it always was, with the single account and no restarting at the log in screen? Would a simple re-installation of the operating system fix things?

Thank you for your time.

To disable the Guest User account, open System Preferences->Users & Groups. Click on the padlock at the lower right corner, enter the admin password. Select the Guest User, unselect Allow guests to log into this computer.

Try repairing the permissions on your home folder:

Boot to the Recovery Partition

• Press and hold Command+R until you see the Apple logo
  • If your Mac doesn’t boot, hold down the Option Key while booting to display the built-in Startup Manager and choose Recovery Partition
  • Or manually start up from macOS Recovery over the Internet, hold down Option-Command-R or Shift-Option-Command-R at startup
• Open Terminal and type repairhomepermissions
  • For macOS, try diskutil resetUserPermissions / `id -u`

Something odd you can’t fix? Sierra re-introduces repairing permissions

We stopped repairing permissions, because of SIP. Now Apple recommends it for a wide range of problems – only this repairs them on your Home folder.
