Does the 2012 model have the same GPU issues as the 2011?
It was working fine then the display got glitchy.
So I booted into single mode and typed the nvram gpu-power-prefs code and it worked. Now I'm wondering if the GPU died…
But then again I remember seeing a Louis’ video about bad soldering on 2012 models but I think it was the Retina one. Does the non-Retinas have bad soldering too and if so does the symptom look like it does in this picture…?
