First of all, I want to give a big shout out to this forum and to everyone who has contributed with their builds and effort as you guys were the main inspiration for me in considering this in the first place.
Second, I have attempted to set this up with an older Windows 10 Pro (Bootcamp, can't remember the build) but to no avail. I might have missed some steps or did something wrong but I tried most of the Code 12 solutions without any success. As a last resort, I decided to simply reinstall Windows and give it another go as that's how the ball sometimes bounces with Microsoft.
To my surprise and with a bit of luck (explained below), it worked without any other fix being required.
- I simply downloaded the latest .iso from Microsoft's official website
- (Re)installed the entire Bootcamp setup
- Rebooted in Windows and started the eGPU while selecting the OS
- Left Windows to install the drivers, followed by another reboot
No more Code 12 and I was able to see both the internal M370X and GTX 1070 available and green under the Display adapters in Device Manager.
The trick (lucky strike) for my setup was to have the eGPU connected to the first/upper TB2 port, the one next to the MagSafe connector. Even now, if I connect the eGPU to the TB2 port below, the one close to the USB Type A, I immediately get the Code 12 error. Once I put it back all is well. It might have been already discussed on the forum in another post or I'm sure there's some explanation for this but I do not have it at the moment. Still, I was happy to see this was OK without any other fiddling around.

I am a casual gamer and I love the portable setup that this laptop provides for other projects, so I wanted a compromise in trying to get a best of both worlds.
Whenever I want to play something, I boot in Windows, open up the game, move it to the 3rd screen (GPU HDMI output is extended to a 3rd screen), switch my monitor from DP (Macbook) to HDMI (GPU) and that's it! I am also noticing the
slight FPS increase if I the game is running directly on the GPU output versus having it running on the TB output, as discussed on other threads.
The thrills I get for being able to run the occasional game at decent FPS and knowing that this is basically a platform for the future, as the eGPU's TB3 setup makes it compatible with newer hardware (+ charging capabilities),... priceless.
Saw this build when i was doing some brief research on a possible egpu setup with my 13in early 2015 retina macbook pro and was wondering what your fps and settings are for various games you play. I only have an i5 and less thermal room in this mac but i imagine (more like hope lol) that my benchmarks won't be much different if i used something similar.
TY if you get back to me,
OK, so I just did a few tests and focused on getting the numbers. Here's what I have:
CS GO (Casual with bots on Dust II)
Settings (automatically configured by the game on a fresh install)
- Display Mode: Fullscreen Windowed
- Resolution: 2560x1440
- Details: Auto: High, 8X MSAA, FXAA disabled, motion blur disabled
Run 1 - TB2 (Macbook) output: 40-70 FPS
Run 2 - HDMI (GPU) output: 70-140 FPS
During the second run I also had my second monitor (HDMI output of the Macbook) also turned on to keep an eye on the Task Manager and I was seeing the CPU usage at around 25-30% and the Nvidia GPU usage between 50-70%. GPU temperature was around 45-50 degrees Celsius, although I did not play for a long time.
FIFA 19 (matches against the AI)
- Display Mode: Full Screen
- Resolution: 2560x1440
- Details: Rendering Quality - Auto, DirectX 11.0, Frame Rate set to No Limit on fps just for this test as I usually set it to 'Lock at 60fps'
Run 1 - TB2 (Macbook) output: 30-60 FPS
Run 2 - HDMI (GPU) output: 60-100 FPS
The CPU usage was around 40% and GPU at around 50% with spikes of 90% and the max GPU temp I saw was 55 degrees Celsius.
I also manually configured the rendering quality to high and MSAA to 4x and my FPS counter was showing between 60-80 on the GPU output.
- FPS were recorded during gameplay and not in the menus
- I kept the native resolution of the monitor and I'm sure the FPS would increase if I would lower it in the game settings.
- CPU at idle is around 4-5% as I have Chrome open as well
- GPU at idle is around 2-5%
- This is not a 'scientific' evaluation, but rather a real life human monitored one haha
- I haven't tested triple A titles or anything really demanding, but I would see them running with decent FPS at low settings and lower resolution.
Hope this helps!
Thank you for posting this MacBook Pro (mid 2015) guide since the previous one in the thread was like almost an year ago. Your build is very clean and detailed in instructions.
I'm very happy and excited to see that the latest version of Win10 bootcamp could be fully compatible without code-12 issue. I'll definitely follow your guide to upgrade my 2015 MacBook Pro as well.
