Yesterday I created a new APFS partition with macOS Big Sur. I usually edit some files in /System/Library files to tweak my home setup to my liking, including some display settings. However the steps I usually take to be able to edit these files no longer work.
These steps were:
Boot the Mac in recovery mode and go to the terminal,

Reboot back in to Recovery Mode, open the terminal again
Remount the disk with write permissions using mount -uw /
Make the edits
Code Block mount_apfs: volume could not be mounted: Permission denied mount: / failed with 66
Is there another way to mount the file system with write permissions?
