Akitio Node + Apple TB2->3 dongle + GTX 1080 + external LG 4K monitor on a rMBP 15" 2015, used only w/ Bootcamp.

Works pretty well, and my latest addition is a DisplayPort switch to use the iGPU directly with the monitor (when I'm in macOS) or the external GPU (when I'm in Bootcamp). Performance is great, around ~95% of desktop GPU I'd say.

The only issue is that it needs a particular boot sequence to enable it, when switching from macOS to Windows with the GPU enabled: reboot from macOS, turn on the GPU, the default partition is Windows so Windows will boot with the GPU enabled.

To reboot from Windows to macOS, disabling the GPU: reboot from Windows, hold Option at boot to show the boot menu, then turn off the GPU and boot into macOS.

Not that bad once you get used to it, and having a desktop GPU on my laptop makes it all worth it.

Great info, thank you! Glad to see there's a sub for this too. I'm about to try the same setup.

If it performs well enough, I might just do away with owning a gaming desktop entirely.

Have you tried GSync with your setup?


My monitor only supports FreeSync, so I only have enabled Fast Sync in the NVIDIA control panel, which is monitor-independent.


excellent info, thank you. So the Akitio node works ok with GTX 1080/ti? You mention you only use with bootcamp - but do you know if the MacOS drivers Nvidia provides work ok?


My understanding is that since High Sierra, Mac OS supports eGPUs natively, but only with AMD GPUs and only using thunderbolt 3:

There are some hacks to get other configurations working:

What DisplayPort switch are you using?
