BigSur Help

[dadgivesitago]

Hi
My kids off school with covid and he wanted to do an IT project, as he wanted a Mac.

So i used an old i7 3770 with 16gb of ram and an Rx580 8gb gpu with a bunch of SSD drives and make a pretty decent attempt to have VM's running Windows 10/11 Ubuntu / and Mac

however i cannot passthrough the gpu for the Mac OS due to the following screen it disables the VNC like it does with all the other OS



i have to select the disk each time to load up BigSur however this then means if i passthrough a gpu i cannot connect with nomachine as its before BigSur loads up. Is there a way to make it auto load this disk selection screen so i can passthrough the gpu and connect with no machine.

Its only Mac OS we have this issue with all the others work fine,

many thanks

just incase anyone has this issue and cant find help

Download the opencore on the vm
https://github.com/thenickdude/KVM-Opencore/releases
Unzip the files

then in terminal open

git clone https://github.com/corpnewt/MountEFI
cd MountEFI
chmod +x MountEFI.command
./MountEFI.command

copy over the mounted files to the Empty EFI folder

Grab a copy of propertree
https://github.com/corpnewt/ProperTree

open with ctrl + click on ProperTree.command

use file in the top bar and go to the opencore zip you extracted then in the config.plist in the OC folder
find the second boot option
find the List ShowPicker and set to false save and reboot

or change the timeout from 0 to 5 __ edit

The OS now just autoloads without having to select the drive.


Just need to get the gpu to show up now. Mac is very very very different than linux or Windows.

I hope this helps someone if i get the gpu to actually passthrough i will include that bit as well
