Select "Custom (advanced)" and press "Next" to go on next page. Does running unsealed prevent you from having FileVault enabled? after all SSV is just a TOOL for me, to be sure about the volume integrity. Howard. Thanks in advance. Every file on Big Surs System volume now has a SHA-256 cryptographic hash which is stored in the file system metadata.. For now. Have you reported it to Apple? That leaves your System volume without cryptographic verification, of course, and whether it will then successfully update in future must be an open question. I seem to recall that back in the olden days of Unix, there was an IDS (Intrusion Detection System) called Tripwire which stored a checksum for every system file and watched over them like a hawk. And afterwards, you can always make the partition read-only again, right? As mentioned by HW-Tech, Apple has added additional security restrictions for disabling System Integrity Protection (SIP) on Macs with Apple silicon. Once youve done it once, its not so bad at all. Full disk encryption is about both security and privacy of your boot disk. I suspect that youd need to use the full installer for the new version, then unseal that again. Howard.

I finally figured out the solutions as follows: Use the Security Policy in the Startup Security Utility under the Utilities menu instead of Terminal, to downgrade the SIP level. One unexpected problem with unsealing at present is that FileVault has to be disabled, and cant be enabled afterwards. There is a real problem with sealing the System volume though, as the seal is checked against that for the system install. No need to disable SIP. And putting it out of reach of anyone able to obtain root is a major improvement. If that cant be done, then you may be better off remaining in Catalina for the time being. For a better experience, please enable JavaScript in your browser before proceeding. Incidentally, I just checked prices on an external 1 TB SSD and they can be had for under $150 US. Howard.

If you need to install a kernel extension (not one of the newer System Extensions, DriverKit extension, etc. As a warranty of system integrity that alone is a valuable advance. Loading of kexts in Big Sur does not require a trip into recovery. It is technically possible to get into what Apple calls "1 True Recovery (1TR)" via a reboot, but you have to hold down the power button (Touch ID) as soon as the display backlight turns off. This command disables volume encryption, "mounts" the system volume and makes the change. There are a lot of things (privacy related) that requires you to modify the system partition It shouldnt make any difference. Further details on kernel extensions are here. You can also only seal a System volume in an APFS Volume Group, so I dont think Apple wants us using its hashes to check integrity.

All you need do on a T2 Mac is turn FileVault on for the boot disk. Ensure that the system was booted into Recovery OS via the standard user action. OS upgrades are also a bit of a pain, but I have automated most of the hassle so its just a bit longer in the trundling phase with a couple of extra steps. All that needed to be done was to install Catalina to an unencrypted disk (the default) and, after installation, enable FileVault in System Preferences.

Thanks for the reply! Howard. Why do you need to modify the root volume? Every time you need to re-disable SSV, you need to temporarily turn off FileVault each time. The only difference is that with a non-T2 Mac the encryption will be done behind the scenes after enabling FileVault. So from a security standpoint, its just as safe as before?
