Thanks for your reply. It would seem silly to me to make all of SIP hinge on SSV. User profile for user: Thank you. SSV seems to be an evolution of that, similar in concept (if not of execution), sort of Tripwire on steroids. (I imagine you have your hands full this week and next investigating all the big changes, so if you cant delve into this now thats certainly understandable.) I dont think youd want to do it on a whole read-write volume, like the Data volume: you can get away with this on the System volume because theres so little writing involved, so the hashes remain static almost all the time. Am I right in thinking that once you disable authenticated-root, you cannot enable it if youve made changes to the system volume? NOTE: Authenticated Root is enabled by default on macOS systems. Tampering with the SSV is a serious undertaking and not only breaks the seal which can never then be resealed but it appears to conflict with FileVault encryption too. Thank you. Howard. You'll need to keep SSV disabled (via "csrutil authenticated-root disable") forever if your root volume has been modified. Howard. BTW, I'd appreciate if someone can help to remove some files under /usr because "mount -uw" doesn't work on the "/" root directory. Thank you yes, thats absolutely correct.

Its not the encrypted APFS that you would use on external storage, but implemented in the T2 as disk controller. modify the icons That seems like a bug, or at least an engineering mistake. Im sorry I dont know. So when the system is sealed by default it has original binary image that is bit-to-bit equal to the reference seal kept somewhere in the system. https://apple.stackexchange.com/questions/410430/modify-root-filesystem-from-recovery.

(I know I can change it for an individual user; in the past using ever-more-ridiculous methods Ive been able to change it for all users (including network users) OMG I just realized weve had to turn off SIP to enable JAMF to allow network users. and they illuminate the many otherwise obscure and hidden corners of macOS. Encrypted APFS volumes are intended for general storage purposes, not for boot volumes. I have a 2020 MacBook Pro, and with Catalina, I formatted the internal SSD to APFS-encrypted, then I installed macOS, and then I also enabled FileVault. [] APFS in macOS 11 changes volume roles substantially. I will look at this shortly, but I have a feeling that the hashes are inaccessible except by macOS. Thank you. 2. bless Howard.

So use buggy Catalina or BigBrother privacy broken Big Sur great options.. By the way, I saw about macs with T2 always encrypted stuff, just never tested like if there is no password set (via FileVault enabled by user), then it works like a bitlocker Windows disk on a laptop with TPM ? Howard. The MacBook has never done that on Crapolina. I dont think you can enable FileVault on a snapshot: its a whole volume encryption surely. Howard. Howard. You like where iOS is? We tinkerers get to tinker with them (without doing harm we hope always helps to read the READ MEs!) Now I can mount the root partition in read and write mode (from the recovery): All that needed to be done was to install Catalina to an unencrypted disk (the default) and, after installation, enable FileVault in System Preferences. Always. Ive seen many posts and comments with people struggling to bypass both Catalinas and Big Surs security to install an EDID override in order to force the OS recognise their screens as RGB. What you can do though is boot from another copy of Big Sur, say on an external disk, and have different security policies when running that.

If you can do anything with the system, then so can an attacker. Very few people have experience of doing this with Big Sur. In macOS Mojave 10.14, macOS boots from a single APFS volume, in which sensitive system folders and files are mixed with those which users can write to. Because of this, the symlink in the usr folder must reside on the Data volume, and thus be located at: /System/Volumes/Data/usr. Apparently you can now use an APFS-formatted drive with Time Machine in Big Sur: https://appleinsider.com/articles/20/06/27/apfs-changes-affect-time-machine-in-macos-big-sur-encrypted-drives-in-ios-14, Under Big Sur, users will be able to back up directly to an APFS-formatted drive, eliminating the need to reformat any disks..

Sounds like youd also be stuck on the same version of Big Sur if the delta updates arent able to verify the cryptographic information. Running multiple VMs is a cinch on this beast. Apple doesnt keep any of the files which need to be mutable in the sealed System volume anyway and put significant engineering effort into ensuring that using firmlinks. In Recovery mode, open Terminal application from Utilities in the top menu. Run csrutil authenticated-root disableto disable the authenticated root from the System Integrity Protection (SIP). Im not fan of any OS (I use them all because I have to) but Privacy should always come first, no mater the price!. Im trying to implement the snapshot but you cant run the sudo bless folder /Volumes/Macintosh\ HD/System/Library/CoreServices bootefi create-snapshot in Recovery mode because sudo command is not available in recovery mode. csrutil authenticated-root disable to turn cryptographic verification off, then mount the System volume and perform its modifications.
