[EFI Loader] Error 12 Fix in Boot Camp for Apple T2 Security Chip Macs (apple_set_os loader v0.5)
If you disconnect the eGPU with modified bootx64 in EFI partition - Can it boot normally and use just iGPU without replacing the original file?
@susurs, The modified bootx64.efi would always load up first. If there's no eGPU detected the EFI loader would start Windows with only iGPU. You can also hit the SKIP shortcut key [z] from what I recall.
And of course if you only use the eGPU occasionally and don't want to be bothered waiting for the EFI loader or hitting Z when booting all the time, you could just install apple_set_os on a flash drive. Then just plug the drive in and hold option when you plan to boot with it, otherwise leave it unplugged and boot normally.
Thank you a hundred times, now Mac and Windows boot the same way, with the same noise from the GPU’s fans.
The first time you have to reboot in order to use the eGPU, but you get the notification so it’s all perfect.
Notice: I don’t have bootcamp drivers installed but eGPU just works. Also I’m booting Windows from and external flash drive.
Apologises if this is posted elsewhere.
I have a 2020 MBP with a Radeon Pro 5500M. I use the laptop for 99% windows, I need MacOS for a tiny portion of my job, but I prefer windows.
I was hoping to use the resources provided here to boot my laptop into windows on the iGPU, and maybe get some battery battery life.
I tired a guide and made a bootable USB, which loaded didnt follow through as it could not detect an eGPU.
Any advice would be greatly appreciated.
thank you so much!! With this I was able to get my configuration going to signature. As of today, in 2021, is there no other way to get an EGPU going? at the moment i'm on windows fast ring channel and i have to change port to the card at every boot, i don't know if it's a very stable solution
