Installation steps
MacOSX:
-Use @goalque's EFI-Bootloader to enable nVidia chips. @mac_editor's purge-wrangler does the same job.
-nVidia WebDrivers are not necessary, as the Kepler Chips in side the GPU are natively supported.
-Only for the nVidia card something has to be done, Radeon RX 570 is plug and play from start.
(Note: The screenshot is taken by another mac, but the result is the same. Mojave is well supported with nVidia Kepler GPUs)
Windows:
I could not get it to run in Windows. Two times "GeForce GTX 690" appears in Device Manager, but one is always yellow banged with Error 12. Disabling devices doesn't help. If someone has a tip (or better some experience) about getting it to run, I would be very thankful.

Comments
- This is great setup with a lot of GPU power and possibilities. I typically attach the monitor to the RX570 and the Dual-GPU serves as double processing unit
- MacOSX handles very well Dual-GPUs.
- This and all Kepler chips work very well in Mojave, they are natively supported.
- Unfortunately it won't work with Windows (so far).

This is the most powerful Nvidia eGPU in macOS Mojave! Unless you have another GTX 690 to add. 😀

When I get my hands on a Titan Z or even a Tesla K80, we will see

@itsage I have just got an nVidia GeForce GTX Titan Black and it's impressing. It's a real alternative for Mojave, if someone needs/wants an nVidia cards on MacOSX.

Hey, thx for sharing this guide, u used both and Asus XG Station Pro and Sonnet Breakaway Puck 570 or one?
And can u also recommended how do same with previous model - MBP 15 2013, gt750m?
