I have a problem on my iMac (late 2013) ever since I installed High Sierra (10.13 - 17A405). When my iMac goes into sleep mode because I'm away for too long, or when I manually activate sleep mode (with holding the power button for a few seconds), it always restarts because of an encountered problem.
This gets really frustrating since this is my iMac at my work place and it happens multiple times a day. For my work I have a few programs and browser tabs open and it gets really annoying having to "ready" my computer before I can get work done multiple times a day.
For a temporary "solution" I keep my iMac inactive period (before it goes to sleep) really high (on 2 hours or so), so that whenever I leave my work space for appointments it is still on when I come back. But that is no solution and I still get this problem a few times a day
How can I prevent these reboot? I already tried resetting the PRAM, but don't know what to do other than that.
