2014 15" MacBook Pro (GT750M) [4th,4C,H] + GTX 780 Ti @ 16Gbps-TB2>TB3 (Sonnet Breakaway 550) + macOS 10.14.6 & Win10
SCREEN SIZE: 15,4 inches
CPU: i7 4870HQ
IGPU: Intel Iris Pro
DGPU:Nvidia Geforce 750m
OS: macOs Mojave 10.14.6, Windows 10 build 1903
Graphics Card: Asus Nvidia GTX 780 Ti Direct CU II 3GB
MOJAVE : Step 1: Disable SiP
Step 2: after boot Install purge-wrangler.sh https://github.com/mayankk2308/purge-wrangler/wiki/Beginne r's-Guide
Step 3: reboot and 780ti fully supported and recognized. There is no need to use Purge Nvda. You can use laptop Screen (Use finder to find the application, right click, Prefer Egpu option in Mojave) , or external monitor for more perfomance.
WINDOWS 10: Step 1: Plug in your enclosure
Step 2: Boot
Step 3: Install latest Nvidia desktop drivers and you can normally use external monitor with the egpu. if you want, you can DDU 750m bootcamp drivers before installing the drivers for the 780ti egpu, but for me, it made no difference.
Benchmarks Mac Os Mojave 10.14.6 VALLEY internal monitor 58,3 fps (1440x900 extreme preset) external monitor 60,6 fps (1920x 1080, extreme preset)
I noticed a big performance difference between internal and external monitor. I was playing dead effect 2 on MacOS x and I had 93 FPS average on internal screen (1400x900 resolution). When I plugged my egpu directly to an external 1080p monitor, FPS went straight away to 140. If you want to have the best possible gaming experience with your 780 ti Egpu, you need to run games on Bootcamp. Driver optimisation is much better in windows 10.
After 2 weeks edit: In some rare cases, when benchmarking or heavy gaming sessions, egpu crashes under macOS. In windows, everything is absolutely stable.
Windows 10, Heaven full HD ultra extreme Preset: 72 fps. That is pretty close to the average desktop 780ti performance
