I have a Mac Mini (Late 2014 model bought in 2016) which has a problem that the display stops working regularly.
So the Mac Mini is largely a Media Server which means it mainly needs to transcode media. Sometimes when I try to wake the display, it doesn’t seem to respond, either to a wired keyboard, or Apple Trackpad.
But if I then access the Mac Mini via VNC the Mac Mini responds and works properly, just the screen doesn’t come on. So I have to reboot to get the screen to respond.
I’ve tried different monitors and connections to the monitor, and this makes no difference.
It’s not down to a timing issue( e.g. it regularly happens after 8 days) it’s not the hardware (i’ve Had the logic board replaced twice by Apple) it’s not a particular activity i’m taking as far as I can see.
I’ve tried to use a different login profile and it doesn’t happen, but then i’m not doing anything too strenuous on a different clean profile.
I’ve backed up, set to factory and restored from backup…
Has anyone got any ideas or tips please before I bite the bullet and have to spend a weekend reinstalling this thing from scratch?
