Been messing with this for a week or so and have found a reliable way to boot using an Nvidia card on a 13" MacBook Pro Retina from early 2015, which is known for having a lot of issues.

Here goes:

  • Shut down MacBook & eGPU
  • Boot into Windows 10 & do not connect/power on eGPU
  • Shortly after boot completes, click Start, then Restart
  • Right after clicking restart, power on eGPU quickly but do not connect the Thunderbolt cable yet
  • Make sure to hold Option again whilst your MacBook reboots
  • On the boot menu, wait until the WiFi loading spinner stops, then boot into Windows
  • Connect Thunderbolt cable as soon as blue Windows logo appears, but before the loading spinner starts

These steps work 100% for me now.

TL;DR, shut down fully, boot into Windows, click Restart, power on eGPU, then connect Thunderbolt right at the Windows logo after reboot.

Hope this helps!

I have made my MacBook pro works (under WIN10) and want to make some more details on implementation and results from it. I have been year long CSGO player and currently been on PUBG a lot so high [email protected] for 144hz external monitor is a must.

For implementation: First install windows 10 via bootcamp, install bootcamp when @win10.

Then to have proper connection: Disconnect sonnet(power on or off) fresh boot into win10->restart shortly after and hold control to be in boot menu->wait till wifi spin complete->connect sonnet right after selecting (pressing enter) win10 to boot.

The win10 device manager in display should show Basic display adapter.

Then go to Nvidia website auto search for your driver and it should recognize and download the driver. After installing when prompt to restart the computer, you should shutdown instead and do the proper connection steps described above (by @nelz)

The Asus Strix Gtx1080 tweak II recognize the GPU everytime I establish proper GPU connect by above steps. And I could utilize to OC or change fans speed of the GPU. Also I am returning Akitio node and keeping my Sonnet. The Sonnet 350 is much quieter and better feels in quality.


PUBG all low setting and ultra AA gives me ~70 fps @1080p

I will be testing my MSI gs63vr w/1060dgpu+6700HQ later this week to see if better performance result (vs dgpu).

Hello! Thank you for this guide! I was wondering what thunderbolt 3 to thunderbolt 2 adapter you're using.


To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@dalekcaan, the use of TB3 enclosures on a TB2 system has only proven possible using the uniquely bidirectional Apple TB3 to TB2 adapter. This is mentioned in the Buyer Guide.
