[Solved] Mac mini 2018 working 50% of the time..
I know I have less to complain about than a lot of people here who can't get their systems working, but if anyone has some insight it would be appreciated.
I followed the entire guide, and boot from EFI.
I have to be very precise with timing to make my devices connect.
I turn on my system holding option. And within a total of 5 seconds I turn on the Egpu, hit enter on EFI (EGPU is powering on but is recognized) before I select Boot Windows as fast as a possible. If I succeed I get the spinning dots and Windows boots and my EGPU is recognized and functional.. yay!
If I'm too slow, or if the EGPU was on and connected before I turn my computer on, windows will not Boot up (windows logo boot loop). It's annoying when it takes me 3 or 4 attempts just to boot windows.
If I hotplug while in windows I get an error 12.
I'm wondering if anyone knows what I need to change to have bootup be less finicky and just work. Or to be able to hotplug by disabling *somethings* so that my computer has enough available resources.
I thought the windows boot loop was caused by not recognizing the EGPU (only the iGpu) and then crashing.
Does anyone have any insight or experienced anything similar?
@danny_fong, Which EFI loader are you using? My guess from reading your symptoms is that you're using automate-eGPU EFI. On Apple T2 Macs such as the 2018 Mac mini, I'd recommend using the modified apple_set_os.efi v0.5 loader instead.
