Ok, so at first, I would get a "graphics scramble". I had heard it was a "glitch" in safari, but after Apple looked at it (repair depot), they replaced the logicboard (2nd time). Fast forward 2 months, and now i am getting this "scramble" in Aperture, PS4, iTunes, etc. It is random, but happening more frequently. I google imaged (because I can never anticipate to get a screen shot, as it is random and I am caught off-guard) this. Mine is a little different that this, but you get an idea.. I am assuming this is the logic-board going out yet again? I made an appointment for Saturday morning. I will bring all my repair receipts (like 5 of them)..maybe I can finally get a new one?
