You can verify with "csrutil status" and with "csrutil authenticated-root status". Im hoping I dont have to do this at all, but it might become an issue for some of our machines should users upgrade despite our warning(s). One major benefit to the user is that damaged system installs and updates are no longer possible, as they break the seal. Sounds like youd also be stuck on the same version of Big Sur if the delta updates arent able to verify the cryptographic information. Howard. This in turn means that: If you modified system files on a portable installation of macOS (ie: on an external drive) via this method, any host computer you plug it into will fail to boot the drive if SSV is enabled on the host. Howard. Boot into (Big Sur) Recovery OS using the . To remove the symlink, try disabling SIP temporarily (which is most likely protecting the symlink on the Data volume). So much to learn. Thank you. . But no apple did horrible job and didnt make this tool available for the end user. You can run csrutil status in terminal to verify it worked.

Hello all, I was recently trying to disable the SIP on my Mac, and therefore went to recovery mode. Assuming you have entered the Recovery mode already, by holding down the Power button when powering-up/rebooting. Just reporting a finding from today that disabling SIP speeds-up launching of apps 2-3 times versus SIP enabled!!! Im not fan of any OS (I use them all because I have to) but Privacy should always come first, no mater the price!. As I dont spend all day opening apps, that overhead is vanishingly small for me, and the benefits very much greater. In Big Sur, it becomes a last resort. Well, privacy goes hand in hand with security, but should always be above, like any form of freedom. Very few people have experience of doing this with Big Sur. https://developer.apple.com/support/downloads/Apple-File-System-Reference.pdf, macOS 11 Big Sur bezpieczniejszy: pliki systemowe podpisane - Mj Mac, macOS 11.0 Big Sur | wp, https://github.com/rickmark/mojo_thor/blob/master/SSV/mtree.i.txt, Michael Tsai - Blog - APFS and Time Machine in Big Sur, macOS 11 Big Sur Arrives Thursday, Delay Upgrades - TidBITS, Big Sur Is Here, But We Suggest You Say No Sir for Now - TidBITS, https://github.com/barrykn/big-sur-micropatcher, https://arstechnica.com/gadgets/2020/11/apple-lets-some-big-sur-network-traffic-bypass-firewalls/, https://apple.stackexchange.com/questions/410430/modify-root-filesystem-from-recovery, Updates: Sierra, High Sierra, Mojave, Catalina, Big Sur, SilentKnight, silnite, LockRattler, SystHist & Scrub, xattred, Metamer, Sandstrip & xattr tools, T2M2, Ulbow, Consolation and log utilities, Taccy, Signet, Precize, Alifix, UTIutility, Sparsity, alisma, Text Utilities: Nalaprop, Dystextia and others, Spundle, Cormorant, Stibium, Dintch, Fintch and cintch.

System Integrity Protection (SIP) and the Security Policy (LocalPolicy) are not the same thing. Without it, its all too easy for you to run software which is signed with a certificate which Apple has revoked, but your Mac has no means to check that.
