Hi there guys. I've been searching this forum for 2 hours now and I can't find the solution to my problem so I'm just gonna do a post. 
I have a Macbook Pro 15'' TB2 Nvidia GeForce GT750M and an Aorus Gaming Box 1070. My OSx is High Sierra 10.13.4. I managed to install my eGPU using this setup
https://egpu.io/forums/mac-setup/script-fr34ks-macos-egpu-sh-one-script-all-solutions-fully-automated/paged/1/

The only thing I had to do different was to connect the eGPU only after I see the Apple Logo. Otherwise I had a black screen and cannot see anything. Anyway. So I connected the egpu and when I open the system preferences I can see my eGPU. Also I did some render tests which I clearly set to do on eGPU and was working flawless... However all the apps are still running on my GT 750M. I don't know how to change from that GPU to use only the eGPU. I tried to disable my laptop monitor using SwitchResX, but the apps are still running on the discret GPU. Here is the benchmark which looks quite bad for me and you can see clearly that it's doing the benchmark on both GPUs which lead me to think that somehow I need to disable it : 

I really have no idea what should I do. I really think it may be the fact that I hotplug the eGPU after I turn on the machine, but I'm not sure how else should I do. Also I tried to disconnect the monitor from the Aorus Box and only connect it a bit time later, but still the same.

Thank you

I would suggest uninstalling and installing the script again, maybe something went wrong during the installation. I have tb1 mid 2012, working flawlessly for me. And this question should be posted in the script forum, it would be answered faster.

@ovi_stoia use the --uninstall parameter?

a little off topic, but did you managed to get this setup working for windows?

No... I didn't even tried. I kinda need the GPU on OSx. But do you think I should try doing it on Windows?

you can try, but i highly doubt it'll work.. i have the same setup as yours, just aorus 1080. osx doesn't seem to be able to support open GL stuff, probably thats why your benchmark is not optimising the egpu. i've tried windows but it just won't detect the egpu sadly..

from my readings in that thread, i believe there are some issues when combining nvidia egpu with nvidia dgpu. there is some mentions of other issues with combinations of nvidia e/dGPU in the "read me" of the script.

So in your case you didn't manage to make it work at all? You get the same performance as me?

I can make a guide if you're interested

@simplekitten I managed to make it work on OSx... I got like 90fps in heaven and also tried with a few games that I had, like CS:GO and it's insane. Here is a link where it explained very well what I had to do. Maybe you can try it too.
