Sometimes at night I will lay on my couch which is in the same room my iMac is located in. Even though it’s asleep it will randomly turn the screen on and then it will go right back off. The whole incident lasts maybe all of 10 seconds. I’ve been laying here tonight and it’s probably happened about half a dozen times in the 2 hours I’ve been in the room without ever going near it.
I’ve tried doing some searching and this appears to have been a problem that has cropped up but I have trouble locating anything about it happening to a machine from this decade. I couldn’t really find a definitive answer on what it could be and a fix.
Does anyone know why this happens and how I can stop it?
