I'm running a MBPr late 2k13 15". EVGA GTX 970 + Akitio. When I first got it, I didn't have a riser, and the GPU would boot me in, no problems etc. But it crashed every single time I tried a game. I used two PSU's (550W psu for gpu, and one for the akitio) After I got a riser, the problem stopped, and now I'm only using the 550W psu. So in my case, the riser is 100% essential.

Haven't checked in on a while. Is it still not possible to use GTX 970+ rMBP 15" Late 13,iris pro with external monitor on OSX Yosemite?

Thanks alot, goalque. But is there any reason for me to use egpu on OSX at all if I cant use ext.monitor?

Where do I do this? I see nowhere it says 14B25. EDIT: I managed to do it! It gets recognized now, although its a bummer it wont connect to external with hdmi.

Yes, and I have installed 343.01.02f03.. This is very weird. No kext loaded it says..

Yes, it is enabled. And when I open the web driver via settings, it says that it`s not compatible etc etc.

ignore, double post...

Hello. I'm trying to setup GTX970 on yosemite. I've changed the 3 kext files, but I still get no kext loaded when I boot.. What am I doing wrong? NVDASUPPORT.KEXT IONDRV Can't take picture of applehdacontroller, because its too long, but I did the same on it.

Yea, thx, I tried with external screen + a little OC, and my score is tons better. NVIDIA GeForce GTX 970 video card benchmark result - Intel® Core i7-4750HQ CPU @ 2.00GHz,Apple Inc. Mac-3CBD00234E554E41

NVIDIA GeForce GTX 970 video card benchmark result - Intel® Core i7-4750HQ CPU @ 2.00GHz,Apple Inc. Mac-3CBD00234E554E41 Its just the graphics score that is low.. Ive tried changing PSU + TB cable now, but its still like that.. The GPU doesnt reach 80celsius even, so I dont really know what the problem is.. Will changing to UEFI help??

Hello. I just finished my setup, but I'm seeing low gpu scores on 3dmark firestrike etc. I get 7300, while most of you are getting 8,5k + with the same setup. Does anyone know the problem? Here's my full setup (Im using internal retina screen) GTX 970 EVGA SC 16x to 16x Powered Riser rMBP 15" Late 2013 with iGPU (5200) Akitio Thunder2 PciE solution 600W PSU 1. Does UEFI windows affect performance? I have bootcamp windows. Will changing to UEFI improve my performance at all? 2. Im using the TB cable from Akitio. Will changing it to apple official 2meter affect my performance?

Alright, sounds good! I tried method 2 today, but the gpu always crash when I enter games etc. Is this because the akitio cant supply enough power? i get driver crash + bsod.

Hmm, you're not using a riser with the gtx 780? Do you think I could do the same with a gtx 970?

Do you think I can power the GPU up without a riser? My riser will arrive in 1 week, but my other parts will arrive on saturday. With DC jack, do you mean akitios?
