I finally moved over to Big Sur yesterday. I was a bit surprised when the old path of replacing the system logo didn't work. Took me a bit to figure out how to get it to work, but here we are.
Process I took.
First you'll have to disable secure boot.
Boot into Recovery.
csrutil disable csrutil authenticated-root disable
Ensure SIP is fully disabled.
Figure out which is your Big Sur drive.
Mount the drive and open the relevant folders.
sudo mount -o nobrowse -t apfs /dev/disk5s5 ~/Desktop/Logo/back sudo mount -uw ~/Desktop/Logo/back open ~/Desktop/Logo open ~/Desktop/Logo/back/System/Library/PrivateFrameworks/SystemDesktopAppearance.framework/Versions/A/Resources/
Backup your current Assets.
cp -p ~/Desktop/Logo/back/System/Library/PrivateFrameworks/SystemDesktopAppearance.framework/Versions/A/Resources/Assets.car ~/Desktop/Logo/Backup
Terminal copy. If it gives you an error, then manually copy in finder.
cp -p -f ~/Desktop/Logo/Assets.car ~/Desktop/Logo/back/System/Library/PrivateFrameworks/SystemDesktopAppearance.framework/Versions/A/Resources/
Manually copy Assets.car to ~/Desktop/Logo/back/System/Library/PrivateFrameworks/SystemDesktopAppearance.framework/Versions/A/Resources/
Finally use bless to create a snapshot. If you don't do this, you may have to reinstall the OS on the next reboot (ask me how I know )
sudo bless --folder ~/Desktop/Logo/back/System/Library/CoreServices --bootefi --create-snapshot
With the backup of your Assets (or the one I have zipped). You can use ThemeEngine to modify the car file.
The one that works with Big Sur and Catalina is over at github
