I have just purchased a Macbook Pro 15" Mid 2012 2.7gb. Now I did not think these machines had any defects such as the early 2011 had.
However, I first noticed that when shutting down the Macbook is would display a grey screen as attached.
Now when just starting up the Macbook and just leaving it sitting about 5 minutes later is will do the same, it also does this when running a youtube video especially a 8k vid.
Any ideas what this could be, maybe a GPU issue as the early 2011 had?
Anyone come across this and managed to resolve this?
I am hoping it is an easy fix otherwise the Macbook will need to be sent back.
