Hey all -
So I have several devices that are forcing logouts after 30 minutes. The checkbox in question is in System Preferences > Security & Privacy > Advanced ... > Log out after XX minutes of inactivity.
The strange part is that this only affects some devices. My personal device, an early 2015 13" MacBook Pro running 10.11.6, is not affected, while several of my development team running mid 2015 15" MacBook Pros on the same OS version are affected. Profiles to each of these machines are identical.
I created a configuration profile to address this specifically via LogIn Window > Options > uncheck Log users out after XX minutes of inactivity. I pushed this to the all devices (affected and not) and verified installation, and this checkbox STILL re-enables itself on the problem machines.
I'm pulling my hair out at this point, any ideas are greatly appreciated.
