@lbmdderek The issue occurs due to disabling the 750m. On my end, I cannot do anything and I do not have that Mac for testing anymore. Consider it a limitation of purge-nvda. Clamshell is not supported with eGPU on TB1/2 Macs IIRC.

Hello !
I as able to make my (MacBook Pro mid-2015 15' with Intel Iris Pro)  R9 270X connecting using an Akitio Node Thunderbolt 3 (using an original TB3 t TB2 adaptor from apple) work, but with macOS Mojave (10.14.2) I was not able to make it work again....

Do you know why ?

In that time I modified my AMD7000Controller.kext....
Any suggestions ?

Thanks !

@daniel_chaves Updating macOS undoes any kext modifications. Re-use the script’s AMD option and choose to enable legacy support, or do the same modifications you made earlier when you had a working setup.

here are a couple of screenshots in case anyone could help.
After 5 days of various and multiple attempts ,I still can't get to have my Nvidia card shown.Akitio node pro-1070ti (also tried 960)-apple TB3->2,apple TB2 cable,macbook pro mid2014 750m-hdmi from egpu
 to lg ultra wide monitor
Nvidia drivers and cuda, installed with SIP enabled and prior to running any scripts.

After so many unsuccessful attempts, it seems that the problem was with Akitio Node Pro.
As soon as I used the Razer Core X instead, everything is working fine!!!
So happy!
Thank you @Mac_editor!

Is there any way I can disable the internal display and only use external display with egpu?

Also,what about audio via HDMI?Is it possible?

@georgios_lachanas Great to hear! You should be able to disable the internal display using DisableMonitor or SwitchResX.

I’ll try with switchresx 
Is it normal that dgpu (750m) is not present in activity monitor (GPUs usage) nor in DaVinci resolve settings?It’s actually disabled using pure wrangler and pure nvda?

@georgios_lachanas normal because it was disabled using purge-nvda.

@quangquach interesting. Worst case the NVRAM method should have worked. Are you sure the mux was correctly set when you applied the commands (automatic graphics switching does not work and only igpu is used)? Sometimes the nvram power-prefs command does not apply changes.

@mac_editor Thank you very much for your help, I feel quite frustrated honestly. I have no idea about nvram and works behind. I've also tried the goalque's USB solution  https://egpu.io/forums/mac-setup/automate-egpu-efi-egpu-boot-manager-for-macos-and-windows/ but the issue is exactly like what I have with purge-wrangler

There must be something wrong with my macbook, I may try to look more into it sometimes later. On the bright side, at least my bootcamp can use the eGPU.  Roll

Just noted down if anyone happens to stuck with the issue like mine, I've finally managed it to work with automate-egpu-efi with Nvidia drivers installed from https://github.com/Benjamin-Dobell/nvidia-update. Previously, I tried both purge-wrangler and automate-egpu-efi but with the Nvidia drivers installed from the purge-wrangler script. It's hard to tell the reason but I suspect that was the Nvidia version issue.

Thanks again, @mac_editor and @goalque (and Benjamin Dobell) for amazing scripts.
