How To: eGPU-Accelerated Internal Display in macOS  

Hi,
maybe this question have posted yet, but I don't find a real solution for me.

I wondering if can play 3D games  (like world of warcraft) directly on my macbook pro screen with macos OR is it mandatory to buy an external screen. 

I see so many topics saying ok or no ok > so 'im lost.

My rig : macbook pro late 2013 and I want to buy AKiTiO Node + RX 580.

Thanks all

Success with this method for MBP w/TB 2016 10.13.6 and using geekbench to verify acceleration. But a few issues. I lose my finder/apps side bar from either screen and have to open apps through search function in upper right corner. Also it becomes difficult to determine which screen is regular and which is accelerated as the "switching" option feels broken after I switch a few times... maybe it takes some getting used to. Also not sure about this "1440x900 60Hz" setting that I'm matching for internal and ghost external... MBP has retina display and I'm confused why this seems to be the go-to setting to get everything working right.

@esatamacmodular For High Sierra, you can alternatively use set-eGPU.sh to accelerate apps.

I have a 15" MBP 2014 with a Nvidia 1070 Aorus Gaming Box, and by using  THIS method I'm able to use both internal display and/or an external monitor. Notice that running games on internal display would be slower because data have to travel both from the mac to the Box and vice versa.

@mac_editor, @ricc thanks! I see that purge wrangler links to set-eGPU.sh when it talks about internal screen acceleration. Since I had the ghost plug I just used that, but it sounds like this is a better solution.

I don't understand
when I drag the white bar to the eGPU display, my iMac monitor changed to eGPU display.
How can you turn the eGPU display to primary while the iMac internal monitor still displaying dGPU?

Used this code on a 2015 iMac and a sonnet encloser with rx  580 works flawlessly
