automate-eGPU EFI - Mac bootscreen on eGPU

@goalque Too bad, was really keen to help. Do you have a rough timeline (i understand you're not in a hurry) to release something for the community? -
automate-eGPU EFI - Mac bootscreen on eGPU
anarki replied to euqlaog's topic in Apple eGPU discussion
Hi @goalque I'd also be interested into helping out with beta testing, but even possibly documentation (Markdown format or something) on steps to take and exceptions. I just "discovered" the world of eGPU and possibilities for my macbook that was overheating when playing :-) I just bought a few parts and I want to help out (testing & docs?) as I think it's a very nice idea. I'm a developer myself but with no experience in EFI stuff. My current setup (not yet assembled): MacBook Pro (Retina, 15-inch 2013) with NVIDIA GeForce GT 650M with 2GB of GDDR5 memory and automatic graphics switching AKiTiO Thunder2 PCIe Expansion Box Asus GTX750TI-PH-2GD5, GTX750 TI, 2GB GDDR5, 128bit MacOSX El Capitan (10.11.6) Edit: I avoided buying GTX 1060 because of the missing drivers for MacOS, but I plan to upgrade once 1060 is usable in MacOS Edit 2: System installed, but I got into problem now with HDMI output bug from Asus. I saw recommendations to switch vbios to Palit version to fix it, but I don't have a windows installation to do it. Was hoping to be able to test stuff by using your EFI program to somehow load Palit at boot time Edit 3: I was able to bet Palit bios and some other GM107 bios on the card. The GM107 finally activated my output, however I get instantly I see all icons GPUPanic.cpp:127. I also tried on another MacBook 13" with El Capitan with the new bios and same behaviour. Edit 4: So I finally tried a lot of VBIOS for my card, and a few NVIDIA Web Drivers and various configurations and reboots, testing both automate-egpu script and the demo provided. So far: - I only tested stuff in Mac OSX El Capitan - https://www.techpowerup.com/vgabios/183014/183014 has been the most stable VBIOS, but only outputs to VGA - All from https://www.techpowerup.com/vgabios/?manufacturer=Asus&model=GTX+750+Ti are pretty stable, but none show signal on anything else ouside VGA - I tried both from https://www.techpowerup.com/vgabios/153914/palit-gtx750ti-2048-140127 and https://www.techpowerup.com/vgabios/153797/nvidia-gtx750ti-1536-140203 and all give signal on HDMI and DVI, however all crash my OS (EL Capitan) with the NVIDIA driver - I tried some VBIOS from forums GM107.rom and GM107BACKUP.rom both showing same behaviour as Palit - VGA is really annoying, as the connector is close to the bottom of case, and you need to open it up and leave card 75% only plugged in to get a monitor connection (I don't recommend this) - I got HDMI to work with the EFI demo (after reading the forum on how it's done on page 2 and 3) for switching monitor (I will test all various VBIOSes that I've tried, but GM107 worked) - I also got a procedure on how to flash your card on Macbook without using windows - I'm using a bootable linux and two USB sticks - I hope to release an ISO that will make it easy for everyone to just boot and flash - When flashing I needed sometimes to restart 2-3 times the macbook until boot prompted output on HDMI port and nvflash recognised both cards - Best results were with HDMI I forsee no bright future for my Asus at this rate .... Thanks
