I have a mid 2011 I Mac 27....started having some trouble with it shutting down and some graphic issues (green horizontal strips) After a hour on the phone with apple being on hold and getting transferred from one person to another with no results or reasonable result or solution for a repair I took the unit to Best Buy /Geek Squad They have backed up the hard drive and done diagnostic. They have informed me that the graphic board is bad and the graphic board is part of the logic board. They also informed me that they could not make this repair.
Please give your best advice on how this could be handled.
