In addition, you can boot a custom kernel (the Asahi Linux team is using this to allow booting Linux in the future). This command disables volume encryption, "mounts" the system volume and makes the change. Why choose to buy computers and operating systems from a vendor you dont feel you can trust? Howard. molar enthalpy of combustion of methanol. Yeah, my bad, thats probably what I meant. any proposed solutions on the community forums. This will be stored in nvram. Hi, Apple cant provide thousands of different seal values to cater for every possible combination of change system installations. Could you elaborate on the internal SSD being encrypted anyway? But Im remembering it might have been a file in /Library and not /System/Library. Im guessing theres no TM2 on APFS, at least this year. I will look at this shortly, but I have a feeling that the hashes are inaccessible except by macOS. i made a post on apple.stackexchange.com here: A simple command line tool appropriately called 'dsenableroot' will quickly enable the root user account in Mac OS X. Again, no urgency, given all the other material youre probably inundated with. Ive installed Big Sur on a test volume and Ive booted into recovery to run csrutil authenticated-root disable but it seems that FileVault needs to be disabled on original Macintosh HD as well, which I find strange.

Each to their own Although I havent tried it myself yet, my understanding is that disabling the seal doesnt prevent sealing any fresh installation of macOS at a later date. Enabling FileVault doesnt actually change the encryption, but restricts access to those keys. Those familiar with my file integrity tools will recognise that this is essentially the same technique employed by them. Of course, when an update is released, this all falls apart. If verification fails, startup is halted and the user prompted to re-install macOS before proceeding. In Mojave, all malware has to do is exploit a vulnerability in SIP, gain elevated privileges, and it can do pretty well what it likes with system files.
