macOS 11 Big Sur
BaseSystem Verification: enabled
Here's the proof Also it says right there - unknown (Unsupported configuration).
This is what SIP disabled looks like:System Integrity Protection status: disabled.
how do I disable that? When I do "csrutil disable", it just responds "system integrity protection disabled", like everything is OK. Also, like I mentioned previously, it refuses to do "csrutil authenticated-root disable" 🙁
I might have figured out the problem. It appears that the recovery partition is still High Sierra for some reason. At least this is what it suggests to install. So, I guess, the way to do it is to create a USB Big Sur installer, boot from it into the recovery mode and then tell Terminal what to do... Big Sur is surreal indeed.
This is insane... I tried to create a bootable USB drive using a well-known commant "sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/UNTITLED --nointeraction" but Terminal said "command createinstallmedia not found"...
I figured it out. Once Big Sur is installed, creating a bootable USB drive involves one extra step. If the installer is in the Applications folder, it ain't gonna work period, as the system protects applications from a prying eye. It needs to be copied into Downloads, or elsewhere, and only then createinstallmedia will be available for use.
"sudo /Downloads/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/UNTITLED --nointeraction"
After that, boot from the USB drive, launch Terminal, disable SIP and ART. Reboot, launch purge-wrangler (if its prompt does not pop up automatically) and proceed as described.
