I have an early 2013 rMBP.. 15inch 2.7 i7. 16gigs of ram. But for one, the battery needs to be serviced. But also, the MacBook is having display issue as you can see below. Which was my fault (It fell out of the bed).. The black bar down the left side as well as the flickering at the bottom. I went to the Apple Store today, its going to cost about $700 to fix the display as well as put in a new battery. Also, during the diagnostics test at the apple store it was saying their was a graphic cards issue but everytime they ran the test, it froze, so they never was able to complete that test. I was with most of the people on the forum who was waiting on the new 2016 models to come out. I was content on waiting on maybe the next revision that will hopefully come out in early 2017.. I just don't want to put $700 into a 4 year old computer. But just really not sure which avenue I should take.
