I am running Mojave on my NUC8i7beh and I am experiencing this weird issue with sleep: when I try to put the machine to sleep for the first time, the monitor sleeps OK, but 1-2 seconds after the NUC itself goes to sleep, it wakes up again by itself (monitor still stays off). If I press a key/click the mouse, the screen wakes up and I can log back in. All sleep attempts after that work fine (monitor sleeps and a few seconds later the NUC goes to sleep). Wake from sleep is also working OK.
Any ideas what might be causing this?
Also, has anyone actually managed to get *hibernation* working? It is a feature I would love to have, since I take my NUC to my office every day. If someone is interested in debugging this I'd be happy to share my findings so far (after a lot of experimentation).
