Installation steps

Before I ran purge-wrangler.sh I disabled SIP as per instructions on the purge-wrangler page. Then I ran the patch enabling the relevant option for my setup.

The I ran purge-nvda.sh selecting option one for AMD (or so I thought). I got a non boot first time and had to startup command-s.

I forget how much logging in and out, plugging in and out and crashing I actually did before I realised I hadn’t properly utilised the purge-nvda script the first time.

You may also need to use purge-nvda again and select Set Mux to iGPU...

Eventually I enabled all the correct options for my system and after the nth reboot, the external monitor came to life.

In Mojave you have to cmd-i the various apps and select the tick box that says favour eGPU.


Aside from opening Activity Monitor and selecting Window/GPU History, to see when/how much the egpu was being used, I didn’t do any benchmarking.


Minorly annoying amount of rebooting required when you are/not plugged into the egpu, but no big deal.

Noticeable improvement on the Adobe suite after selecting a few extra prefs inside the apps here and there. Adobe and Apple seem to be working together properly for a change.

Hard to totally fathom if certain other apps are using the egpu or not, but on the whole i think it was worth doing.

Also by buying a decent TB3 enclosure you will be able to use it with your new computer if and when you decide that this doesn’t offer you a sufficient performance upgrade.

It is possible to use GPU compute without external monitor? I need using GPU with built-in retina display for Final Cut Pro X.
Thank You!

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