Some people report that if it doesn't work initially (both external + internal display black or internal display showing artifacts), you should try:

  1. Logging in without the eGPU attached
  2. Plugging in the eGPU (check in system profiler that it is detected)
  3. Logging out and logging in again

 

Is there a solution to this work-around?

I have an AKiTIO TB2 Box connected to my 2013 Mac Pro.

I was running fine in 10.12 with the automate-eGPU solution. When I upgraded to High Sierra I had the Black screen issue.

But there are many times I remote in and restart my computer. This workaround obviously will only work if I'm local.

I'm willing to do a fresh install of the OS to wipe out any old info if that's what it takes.

EDIT: Question: It turns out that my internal display is now powered by my eGPU. Can I somehow force the internal display to use either Integrated graphics or, best, dGPU (750M)?

@natemac00 I have similar setup, but with Macbook Pro 2013. It works the same way it worked on 10.12 Sometimes I can restart just fine, sometimes I need to plug the eGPU when the Apple sign appears. I guess if you intend to do it remotely you may have to reboot several times in a row. Idk if rebooting in a row allows to skip the "plug at Apple" step.

First time posting here but really happy this forum exists because it seems like we are all battling with Apple with this issue.

I also have the black screen on boot issue that is fixed by booting without my Mantiz and 1080 attached, logging out, plugging it in and logging back in. Though there are a couple weird issues.

First, the 1080 doesn't produce a picture and if I unplug the cable and plug it back in, it crashes the Macbook Pro

Secondly, none of the other parts of the hub work on the Mantiz. This is unfortunate because I was using it as my USB hub and Ethernet connect to my router. 

Not sure anybody has a solution for this, but thought I'd cast my problems into the problem bag with the hopes we can all resolve them.

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

Got my setup kinda working today.

2016 15" MBP with Touch Bar (factory with Intel HD 530 and Radeon Pro 460) + Akitio Node Thunderbolt 3 + Gigabyte GTX1080 G1 Gaming

Only way i can get it to work is to startup my mac with eGPU unplugged, once i get to the login screen plug it in, then login. Then the GTX1080 shows up in System Profile. The external monitor hooked directly to the GPU works but the laptop keeps using the Radeon Pro 460. 

 

My only concern is that the actual GPU fans only kick in for a few seconds when you first plug in the Node then they turn off. Im guessing the card must not be hitting a heat threshold to turn them on ever? Anyone have any insight? Something i should worry about?

Lol, I had the same impression that there was something wrong with the fans not kicking off. But then I learned that the fans don't work unless under load, so its all good 😛

Well, I can get the eGPU to work on the external display connected to the HDMI, but I cant figure out how to make it work on the laptop display. Can anyone enlighten me on what I need to do?

There are different guides on this site depending on the model of your laptop/OS.

Hey folks! I recently changed my hardware setup too and I'm in a similar boat. I can get macOS 10.13 to recognize my eGPU, and I can get apps to defer work to the eGPU, but I'm hoping to be able to get it to work on the internal LCD of my MacBook.

Hardware: 

Steps:

  1. Followed the original steps for installing NVIDIAEGPUSupport.
  2. Installed Thunderbolt 3 enabler for the Razer Core.
  3. Boot into macOS with Razer Core plugged in. Won't be visible to the system.
  4. Unplug, then replug the Razer Core after booting, will be recognised as 'nVidia Chip'.
  5. Log out, then log back in. System Report will now show the GPU properly loaded (screenshot attached).
  6. (Optionally, unplug the Core again at this point to cause a kernel panic. XD)

For the life of me, I can't get macOS to boot with the Razer Core already enabled to enable the internal LCD. I absolutely must do that unplug-and-then-replug after booting in for the Mac to recognise the Core as being attached, but I'm guessing at that point, it's too late to switch which GPU is powering the LCD.

I'm wondering if it's possible to maybe use some of the old-school GPU utilities built to allow explicit switching between the integrated and discrete GPUs on 15" MacBook Pros. But none of the ones I tried would work on a 13" MacBook Pro, and I'm sure the problem is more complex than that.

Has anyone managed to reliably get their eGPU to power their internal LCD monitor?

I think what some people are doing here is to use a headless hdmi plug into the GPU, and mirror to the internal LCD.

Something like this: 

And also in system preferences -> display, you can mirror and make the system adjust the resolution to the internal LCD.

As far as I can tell from hours of searching, this appears to be the way to do it. I ordered a headless DisplayPort adapter, hopefully that will work. That way I can use the hdmi as well. I’ll report back on Friday if it works or not.
