So I would not do "csrutil authenticated-root disable" myself, but I have part of the purchased software installed in the system partition, if on previous versions of Mac OS I could do it with minimal losses for system security, now I have been fighting for a week to make the partition writable, I I need to install what I need, on what basis does Apple not give me access to my own data that is stored on my computer? Encode the files as you want, but I must have access to any section on my disk

Disable FileVault Reboot into recovery mode and run: csrutil authenticated-root disable Reboot back into MacOS Find your root mount's device - run mount and chop off the last s, e.g. if your root is /dev/disk1s2s3, you'll mount /dev/disk1s2 Create a new directory, for example ~/mount Run sudo mount -o nobrowse -t apfs DISK_PATH MOUNT_PATH, using the values from above Modify the files under the mounted directory Run sudo bless --folder MOUNT_PATH/System/Library/CoreServices --bootefi --create-snapshot Reboot your system, and the changes will take place Troubles: sudo mount -o nobrowse -t afps /dev/disk1s5 ~/mount  Password: mount: exec /Library/Filesystems/afps.fs/Contents/Resources/mount_afps for /Users/user/mount: No such file or directory mount: /Users/user/mount failed with 72
