#Automate-eGPU EFI#
I’ve been working on a completely new application - eGPU boot manager for Mac computers. Installation script is not required as with rEFInd which invokes bless for the changing of the default boot partition. Settings can be done within the app. For more information, see
https://www.techinferno.com/index.php?/forums/topic/10057-automate-egpu-efi-mac-bootscreen-on-egpu/
You can download the demo version here:

#Automate-eGPU.sh#
This script automates Nvidia and AMD eGPU setup on OS X.

WARNING! I’ve observed references to my script where one unnamed and verbally talented buddy has posted untruths, claiming that I have copied a piece of one coder’s work within 24 hours. In fact, I sent my own, detailed ioreg output of Mavericks builds and board-id list mentions within about half an hour when a T|I member told me about the purchase of coder’s app. Before that, I wasn’t aware of this purchase. Never got ioreg contents from coder's customer, never used such an app and never requested information about it. My original discovery (Mavericks kexts comparison) happened months earlier. There is a thread about this, reviewed by T|I admin, including my private messages - no evidence found of any IP theft accusations. |
The script can be executed by two OS X Terminal commands:
chmod +x automate-eGPU.sh
sudo ./automate-eGPU.sh
##Options##
| -a | Switch on automatic mode |
| -m | Switch off automatic mode (default) |
| -url | Install Nvidia driver pkg from any valid web address |
| -clpeak | OpenCL performance test (http://github.com/krrishnarraj/clpeak) |
| -skipdriver | Skip Nvidia Web driver installation (for Kepler cards) |
| -uninstall | Restore original kexts, unload services and delete application support files |
The manual [-m] mode does only the minimum initialization in order to use the eGPU.
The advanced [-a] mode aims to configure everything automatically in the background, so that user can continue working after OS X updates immediately. Resolves the boot screen freezing issue with multi-slot enclosures & dGPU equipped Macs, and is beneficial with the nMP, allowing to use any TB port for booting without issues. It’s likely that you can now run more than one Nvidia Kepler eGPUs externally out of the box with any TB2 Mac, without manual delay. You can switch the mode at any time. Confirmed to work with subsequent OS X 10.11 El Capitan Developer builds (you have to disable System Integrity Protection). The script detects if you have turned it on/off.
OS X 10.11 brings Metal to Mac. I wrote a piece of code to determine if your eGPU supports Metal API. Just follow these steps:
curl -o ~/Desktop/metaltest.swift https://raw.githubusercontent.com/goalque/automate-eGPU/master/metaltest.swift
cd ~/Desktop
xcrun swiftc -o metaltest metaltest.swift
./metaltest
Thanks to jrprice’s NBody-Metal app, a GTX 980 runs 65536 bodies nearly 30 FPS on retina display. Approximately 7 times faster than Iris Pro. A simulation of 32768 bodies achieves 60 FPS. https://github.com/jrprice/NBody-Metal
##What’s new in 0.9.9##
Version 0.9.9 is released with new licensing: https://github.com/goalque/automate-eGPU/blob/master/SCRIPT-LICENSE.txt
-
Native support (experimental) for R9 Nano and RX 480 with a Baffin personality (just remember to turn on -a mode).
-
Nvidia web driver support (experimental) for macOS Sierra beta builds
##What's new in 0.9.8##
- Support for OS X Mavericks 10.9.5 and Kepler cards
- Added board-ids for iMac15,1 and iMac17,1
- Fixed issue #8 goalque#8
- Fixed issue #9 goalque#9 (thanks keymone)
- Fixed issue #13 goalque#13
##What’s new in 0.9.7##
- SetIOPCIMatch() function which sets and appends device IDs (both the AMD and Nvidia)
- Automatic NVIDIA Driver Manager uninstalling
- Minor bug fixes
##What’s new in 0.9.6##
- Support for 2015 Macs (-a mode is required for successful booting with a multi-slot enclosure)
- Prepared for Fiji architecture
- Detects dGPUs for determining the correct [-a] mode behaviour
- Fixed issue #3 goalque#3
- Fixed issue #4 goalque#4
- Checks for the existence of application support path and if the script is ran as root
- Support for OS X El Capitan 10.11 GM
When the [-a] mode is turned on, Nvidia eGPU connected to nMP Bus 0 (port 5 or 6) works, but Thunderbolt Bus 1 or 2 (ports 1-4) require one additional restart and shut down without eGPU.

Thanks to Netstor for testing NA211TB, especially with the Late 2013 Mac Pro.
Thanks to Tech|Inferno forum and Nando’s up-to-date eGPU Implementation Hub, where you can choose the right hardware for you needs:
AKiTiO Thunder2 is recommended with Maxwell Nvidia cards or older AMDs. NA211TB is stable with AMD R9 series.
