Windows won't boot on Mac mini 2018 with only egpu attached after upgrading Catalina 10.15.2
After upgrading to Catalina 10.15.2, Windows shows error 12 with my RX5700.
The strange thing is if I attach both usb-c to dp port and egpu to the Mac Mini, use the source from the dp port and boot into Windows, then switch to the source to the egpu, it worked just fine.
My Windows 10 version is 18362.295
Any one have the same problem?
There's something wonky with headless Macs + eGPU in 10.15.2. My 2013 Mac Pro doesn't boot up as consistently with the eGPU compared to previous versions.
Hello, how did you even get the eGPU working under Windows?
I tried to install Win 1909 under BootCamp and bootet into Windows, after that i turned eGPU on, it will be recognized but after AMD driver installation and restart, Win does not recognize the eGPU (ON during boot). I have not installed one of those EFI or KEXT "hacks" since I have read that some people stated there is no need for this complicated procedure?
So what is the right procedure to make the eGPU work under Windows 10 on a Mac mini 2018?
Thanks in advance!
Same here. I'm unable to boot into MacOS 10.15.2 with only eGPU connected to my mac mini 2018. I see black screen of death. Tried resetting PRAM but it didn't help.
Make sure your display connect directly to Mac mini (source 1) and the egpu (source 2) at the same time. Then power on Mac mini using source 1, the windows will boot but the screen is black, but you can heard the notification sound, then switch to source 2, the egpu will work just fine.
thanks, I will do a fresh install of windows 1909 via Bootcamp!
Is it important to have the eGPU switched on during BootCamp Setup to?
May you can provide details step by step instructions on how you installed Windows and made your eGPU work? Did you have to do something with those KEXT or UEFI hakcs in order to make it work?
eGPU connects on the Thunderbolt Connector right next to the HDMI connector on my mac mini. I read some peaple say its better to use the one next to the LAN port, others say next to the HDMI does also work? So I'am confused!
Or is it OK if I install Windows via BootCamp, boot into Windows, install driver, restart and follow the steps you provided above?
It it crutial that you install the Windows 10 Version 18362.295 if you're using AMD cards.
No other hacks needed, at least in Catalina 10.15.1
