CUDA/OSX Only Setup
tmpkn, in Apple eGPU discussion
I built my eGPU setup with an Akitio thunder 2 and a Zotac gtx 970 a few weeks ago. It worked pretty well, but the fans of the eGPU doesn't change speed, neither under high usage... I heard about zotac firestorm and other drivers that can control the fan´s speed, but I want to keep OS X and don't want to change to windows... So I opened the case checked with a multimeter how high or low the voltage of the fans are, but somehow I touched with both poles of the fans and the whole setup shut down. I rebooted it and the eGPU worked fine, but the fans doesn't move ant all... I disconnected them and powered them separately and they spin! That means that it could only be a software problem.
I hope you can help me
As anyone using nVidia cards with OSX will know, we're limited to the 900 series cards, whether they be in eGPU's, Mac Pro or Hackintosh. Of course there is the AMD option for cards, but they simply don't meet up to any expectation I have of a card comparable to nVidia's hardware.
All of my diggings has shown people saying to wait for nVidia to release webdrivers for OSX and that's going back nearly 8 months now.
Honestly, I severely dislike Windows as an operating platform, and have miles of trouble getting my eGPU to work with it on my MacBook Pro. But, in lieu of Pascal support for the newer 1000 series cards, I WILL eventually switch over. I know lobbying to Apple is a dead cause, because, well, it's Apple, but I've started a petition to try and gather support for convincing nVidia to write webdrivers for 1000 series cards for OSX.
So, sign and share this around, I know it's a long shot but hey, a digital signature costs you nothing.
After many failures here is my little contribution to this forum. This guide will be updated if I find anything new. Any question, just ask.

OSX 10.11.2 Windows 10 pro (Bootcamp BIOS) WebDriver: latest Cuda Drivers: latest
There is a script that automates the whole thing that can be found here , it worked wonderfully on my vanilla 10.11, easy as cake !! Thanks a milion @goalque
For manual installation follow the video below to the letter:
OS X Stable Windows stable
Restarting is quick (apple logo straight away) but starting the computer after a power OFF takes a good 30 sec more to get to the apple logo. Issue with safari not wanting to play netflix somehow; issue with HDCP handshake somehow, works fine with chrome.
Installing Windows 10 (BIOS) (I hate windows :s )
I installed windows 10 via bootcamp, purchased EGPU setup and used the 1.2 version.
I don't remember exactly how the EGPU appeared in the system infos but I think it was recognised as Nvidia gtx 970 straight away.
so after you have installed the latest Nvidia drivers for your eGpu it is time to get the eGpu software running:
Unzip EGPUsetup 1.2 to c:\eGpu run setup-disk-image Restart and load eGpu Setup 1.2, select option 2 Do PCI compaction all exept sata and make sure you have PCI WRITE and ALL ALLOC showing yes Optional: If freeze at the bootloader: edit PCI.BAT replacing a:x.x and b:x.x with 0a:x.x and 0b:x.x (I only found A occurences in mine) (in the editor alt/option+F to access the file menu) Optional: If the settings are not kept after reboot: edit Startup.bat by adding REM in front of all "call vidinit" like so: REM call vidinit... (in the editor alt/option+F to access the file menu) Run test startup.bat Run bootloader Select eGpu setup 1.2 again and now select option 1
If everything goes well you just have to do the last step every time you want to boot into windows with the eGpu
Maybe there is a way to automate the last step but yet to find out. Easy enough for now
Big thanks to @Tech Inferno Fan
This setup is similar to those of bsohn and errin
Hi all I'm selling my lovely eGPU and one potential costumers with an iMac late 2015 asked me if he can use it as simple accellerator for his professional software like After Effects and Premiere. Can you provide more information? Do I still need to install automated eGPU script? Anyone tried this, can you see
the boost using it as an external accellerator and keeping using iMac 5k display as always?
thanks all for the help!
After i run the script for egpu install automation my system sees the card, but Octane demo don't see any CUDA cores. Anyone could help me with this? What could be the matter?
