I have read that the early 2011 MacBook Pro might be the last model supported. I hope so because I still have one, and I must say that this model has done me well. Its still really fast, which it has 16 gb of ram, ssd, and the hi res anti glare screen, and I will not give my machine up!!! I keep new thermal paste in this machine, and I have never had one issue out of it; no graphic glitches. I just can't seem to give in, and buy a new machine. I am crossing my fingers that its supported. My wife has the good ol MD101, but I still love mine better. USB 3 would be great, but thunderbolt to USB 3 works just fine. I use my machine out in the sun all day long, and love having the anti glare. Don't get me wrong those "stain gate" screens sure are nice, but I have a Big Bad Hackintosh with 2 4k screens, 1 2k screen, 8 tb of drive space, 4790k, 16gb ram, GTX 980 ti, Apple Magic Mouse, Apple Keyboard, Apple Magic Trackpad, plus a custom machined case I made on a plasma cutter, but somehow I always pickup my MacBook Pro.
Long story short, Im going for the Early 2011 MacBook Pro with thunderbolt for compatibility. If they don't support it I won't be upset, but I really would not understand why???? I know the AMD 6750m 1gb card does not support metal, but my machine blows away my wife`s that has the integrated hd 4000 that supports metal. I am curious if that is going to be the decision maker because Apple is so crazy about metal nowadays. I know that metal is better than OpenGL, but the AMD 6750m can hang pretty good still! Just keep her cool, or she might exploded!!!!! I am pretty sure thats why everyone had their 2011 MacBook Pro GPU issues because I have never had that issue. I keep Arctic Silver on supply tho....
Don't let my GPU go over 75 Degrees. I think Apple is trying to get rid of OpenGL tho... If that is the case, then I understand my old MacBook Pro might get the boot.
