 ## The Story
 When **Apple** announced native external graphics support for macOS on **Thunderbolt 3** macs, I was ecstatic. Other eGPU users confirmed that it worked on older **Thunderbolt** macs. Being on the Mid-14 MBP w/ 750M, my enthusiasm quickly faded, however, as soon as I plugged in my eGPU and logged out (on High Sierra, of course) - all I could see on the external display was colored lines and glitches. Suspecting that **NVIDIA** drivers were to blame for this, I tried moving kexts associated with the same away from its default location to prevent loading, powered down the Mac, plugged in the eGPU, and booted. It worked (Beta 4)!
 
-I was up and running on my external display - at the cost of no output on the internal display and losing the ability to boot without external graphics connected. So I decided to create a tiny script to help move about the kexts, making it easy to restore the system to its default configuration. Then **@theitsage** on [egpu.io](https://egpu.io) suggested I look into a [macrumors forum](https://forums.macrumors.com/threads/force-2011-macbook-pro-8-2-with-failed-amd-gpu-to-always-use-intel-integrated-gpu-efi-variable-fix.2037591/page-28#post-24886189) where mac users with failing AMD chips were using the same process to prevent the use of the chip - with one major difference - they were forcing boot on the iGPU. This was what I needed to get the internal display to work and ensure external graphics compatibility. This configuration worked on Beta 4, but does not on Beta 5.

-After investigating, thanks to **@goalque** and **@tbl777** on [egpu.io](https://egpu.io), we discovered that only the **GeForce** kexts are to blame. Removing only those are sufficient for persistent iGPU-only boots. **1.2.1** is the first release to support **High Sierra**.

-Finally, on **macOS 10.13.4**, many bugs have been eliminated and **1.2.0** now allows for external AMD graphics to run on macs with discrete NVIDIA GPUs.
