MacBook reboots during a long sleep if FileVault is turned on I've turned on FileVault on my MacBook Pro 2018 (High Sierra) and immediately after this the MacBook started to reboot randomly (mostly) when in sleep.

First I noticed that after putting my Mac into sleep I need to enter a password to unlock it (touch ID disabled) and that all my applications are closed. Looks like a reboot...

Then once when waking up my computer from sleep I got this message "Terminal interrupted logout. To continue logout, quit Terminal". This convinced me that the MacBook is trying to reboot itself during sleep.

It never happened before - but happens during all long sleep cycles (no matter if during the day or night) since FileVault is turned on.

Any ideas how can I troubleshoot this?
I have this problem and found this Preferences -> Privacy &amp; Security -> "Firewall" -> Advanced -> Log out after 60 minutes of inactivity" setting being turned on too!. 

I believe you forgot the  -> "Firewall" -> route in your description!

Thanks this was the solution for me!
