When a user unseals the volume, edit files, the hash hierarchy should be re-hashed and the seal should to be accepted (effectively overwritng the (old) reference) Thank you I have corrected that now. All good cloning software should cope with this just fine. Can you re-enable the other parts of SIP that do not revolve around the cryptographic hashes? That isnt the case on Macs without a T2 chip, though, where you have to opt to turn FileVault on or off. kent street apartments wilmington nc. Run "csrutil clear" to clear the configuration, then "reboot". csrutil authenticated-root disable Yeah, my bad, thats probably what I meant.

Id be interested to know in what respect you consider those or other parts of Big Sur break privacy. That leaves your System volume without cryptographic verification, of course, and whether it will then successfully update in future must be an open question. [] Big Sur further secures the System volume by applying a cryptographic hash to every file on it, as Howard Oakley explains. 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.

SIP is about much more than SIP, of course, and when you disable it, you cripple your platform security. What is left unclear to me as a basic user: if 1) SSV disabling tampers some hardware change to prevent signing ever again on that maching or 2) SSV can be re-enabled by reinstallation of the MacOS Big Sur. Or could I do it after blessing the snapshot and restarting normally? % dsenableroot username = Paul user password: root password: verify root password: I also wonder whether the benefits of the SSV might make your job a lot easier never another apparently broken system update, and enhanced security. d.

In your specific example, what does that person do when their Mac/device is hacked by state security then? Have you reported it to Apple as a bug? 1- break the seal (disable csrutil and authenticated root) 2- delete existing snapshot (s) and tag an empty one to be able to boot 3- inject the kext with opencore (not needed if you are able to load the kext from /S/L/E.. csrutil authenticated-root disable csrutil disable Although Big Sur uses the same protected System volume and APFS Volume Group as Catalina, it changes the way that volume is protected to make it an even greater challenge for those developing malicious software: welcome to the Signed System Volume (SSV). If you really feel the need or compulsion to modify files on the System volume, then perhaps youd be better sticking with Catalina?

Howard, Have you seen that the new APFS reference https://developer.apple.com/support/downloads/Apple-File-System-Reference.pdf has a section on Sealed Volumes? The file resides in /[mountpath]/Library/Displays/Contents/Resources/Overrides therefore for Catalina I used Recovery Mode to edit those files. .. come one, I was running Dr.Unarhiver (from TrendMicro) for months, AppStore App, with all certificates and was leaking private info until Apple banned it. 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. Therefore, you'll need to force it to boot into the external drive's Recovery Mode by holding "option" at boot, selecting the external disk that has Big Sur, and then immediately hitting "command + r" in just the right timing to load Big Sur's Recovery Mode.

I dont know about Windows, but the base setting for T2 Macs is that most of the contents of the internal storage is permanently encrypted using keys in the Secure Enclave of the T2. If its a seal of your own, then thats a vulnerability, because malicious software could then do exactly the same, modify the system and reseal it. One unexpected problem with unsealing at present is that FileVault has to be disabled, and cant be enabled afterwards. But I wouldnt have thought thered be any fundamental barrier to enabling this on a per-folder basis, if Apple wanted to.

Allow MDM to manage kernel extensions and software updates, Disable Kernel Integrity Protection (disable CTRR), Disable Signed System Volume verification, Allow all boot arguments (including Single User Mode). All that needed to be done was to install Catalina to an unencrypted disk (the default) and, after installation, enable FileVault in System Preferences. So it seems it is impossible to have an encrypted volume when SSV is disabled, which really does seem like a mistake to me, but who am I to say. I wish you success with it.
