It’s happened several times…and did it again at 3am this morning. I heard the computer shut down and restart. When i check it out, it reboots like a simple restart…but why?
I was fearing that it’s being hacked somehow and somebody may be obtaining personal information. What should i do to check into it?
I had a problem with mine where the comp would restart itself. Then it started to happen more often. After trying a bunch of things it turned out that the motherboard was bad.
my work computer always is telling me that it’s loaded in some automatic updated and was restarted at night. So that’d be my vote… Luckily my mac always asks me before doing stuff like that.
You should have a little update bubble on the lower right hand corner when you log in that says “your comptuer has had automatic updates installed that required it to be automatically restarted”
as you can see, there are lots of reasons for this to happen - i think you need to stay up one night, and watch it until it happens. once we know all of the events leading up to the restart, we will probably be better able to help you fix it.
