Vertical lines and small squares fix?
Hi guys,
my iMac recently froze and when I tried restarting, some vertical lines showed up but the Apple logo still loaded. Once it finished, some squares popped up all over the screen.
PLEASE SEE VIDEO
I would really appreciate some help.
Update (07/24/2019)
When the little squares show up, the external screen then turns on and is completely white.
So I guess internal display then?
Is dit een goede vraag?
