In fact, the way the Mx Mac boots is that the entire OS is walled off in a read-only, encrypted secure enclave that is on a Volume that is unvisible to the user, then a copy is made to the drive the User can see, but then a snapshot is taken of that copy and the system boots from that snapshot. As part of that process, hashes are calculated of the secure enclave, the copy of it, and the snapshot. If the hashes don't match the hash that Apple has created for that particular version, the entire system is reinstalled as part of the boot process. If the snapshot is bad, but the other two are good, a new snapshot is created. If the snapshot matches the copy, but the copy is bad, a new copy is made and a new snapshot is taken at boot time. So even if it were possible to erase/delete/modify the system font files or folders, they would be immediately restored at the next boot. And yes, Root has no modifcation authority in the SSV where the originals are kept. Apple responded to the bad guys who found ways to embed malware in fonts, images, kexts, etc. And the result was a much more controlled /System folder and no user access to the system files. If you want to yell about it, yell at the bad guys who made it necessary, not at Apple.</blockquote>
