Apple's unreasonable hardening has been the latest deterent to my ever wanting to use macOS as a personal driver. I've got a Mac as my daily driver for work, it can happily stay with work until I can decide how the filesystem is laid out and what folders I, as the root user, can and can't interact with from user land. I own my machine, not Apple.

Current mac OS is pretty well hardened from this, with their current enclaves and needing to boot home to Apple to get keys if things are not 100% right. Not saying you or I can not, but basically means the same cracking tricks you need to use for iPhones. It's not as easy as you describe.

In fact, one of the things they do if mac OS boot detects that root has been modified (it has a crypto index stored away when it was made read-only), the boot rolls back to the last root snapshot -- since they are all read-only that works. In fact, it is a PITA to update/fix things like traditional scripts (for instance the scripts in the /etc/periodic area). Basically, they make it really unnatural to change the root files system, make a new snapshot and index (I have yet to see it documented although, with much pain, I previously created a procedure that is close -- i.e. it once worked on my pre-Ventura Mac - but currently -- fails, so I need to some more investigation when I can bring this back to the top of the importance/curiosity stack (I have a less than satisfying end around for now so I'm ignoring doing it properly).
