[APP] NVIDIA eGPU support for High Sierra (NVIDIAEGPUSupport)  

Okay those of you still experiencing black screen issues. Can you see if you have any bootargs enabled: sudo nvram boot-args

If so, disable them with: sudo nvram boot-args=""

Also, as a last ditch effort, try to create a new partition and installing 10.13 fresh and following these steps.

As I reported before, when I followed the steps from yifanlu's post the setup didn't work on macOS, and when I booted in win 10 it gave me error 12 and the egpu is not working, then and immediately after deleting the .kext file I tested the setup in win 10 again and it worked as usual without any issue.

I'm wondering if the blank screen issue is happening to users with an ultrawide monitors only (same as my case), it could be a bug in the driver itself or in macOS and on 15" MacBook Pro only.

 Is your problem repeatable on every boot?

1) Add the kext -> restart into Windows -> error code 12.

2) Delete the kext -> restart into Windows -> everything works.

I've tried yifanlu workaround two separate times, and after each failure in macOS I tested win bootcamp, I can't say it's on every boot, but I had the same result for two times.

I don't want to generalize, you @goalque know much better than me.

Tried the boot args cmd in terminal but got an error...

No boot-args here. I'm not going to create a new partition right now.

(Same result as for eightarmedpet)

Running out of things to try. Perhaps the next web driver version will fix it.

Edit:

Trying the boot arguments didn't work with sip enabled or in recovery mode. Says data not found either way.

Seems like you need either SIP disabled or to be in recovery to do it.

Thats really odd... I dont recap re enabling SIP but checked and it is... does your App re enable it?

Thanks for the info, may try but I may park it as it isn't going to work on my internal or LG and I rarely plug into my TV (never).

I see from your post history that you're using the Thunder 3. It's not macOS compatible enclosure.

I'm using a Mantiz Venus with the new firmware, is there an enclosure called Thunder 3?

 Sorry, it was devild's post that you quoted:

On the other hand @goalque, have you seen my post regarding my implementation experience when I got my full egpu setup working for the first time?

the post is here:  https://egpu.io/forums/mac-setup/macos-high-sierra-supplemental-update/#post-21402

Again, I don't want to generalize, but I had a very strange behavior in win 10 (bootcamp) after updating the macOS with the subject update, and I highlighted in the post that this behavior should be confirmed by advanced members like you, cause I'm an engineer and I'm not qualified enough in IT or Software Development.

The only reason I'm posting these cases is to grab the attention of advanced users to the scenarios I've went through that might help you figure something to help other users.
