How can I solve this problem? This to me is a violation. Thanks to Damien Sorresso for detailing the process of modifying the SSV, and to @afrojer in their comment below which clarifies what happens with third-party kernel extensions (corrected 1805 25 June 2020). Additionally, before I update I could always revert back to the previous snapshot (from what I can tell, the original snapshot is always kept as a backup in case anything goes wrong). Couldnt create snapshot on volume /Volumes/Macintosh HD: Operation not permitted, i have both csrutil and csrutil authenticated-root disabled. The MacBook has never done that on Crapolina. 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 ? Do so at your own risk, this is not specifically recommended. d. Select "I will install the operating system later". Howard. IMPORTANT NOTE: The csrutil authenticated-root values must be applied before you use this peogram so if you have not already changed and made a Reset NVRAM do it and reboot then use the program. Im sure there are good reasons why it cant be as simple, but its hardly efficient. 3. boot into OS This saves having to keep scanning all the individual files in order to detect any change. Would it really be an issue to stay without cryptographic verification though? Authenticated Root _MUST_ be enabled. I wanted to make a thread just to raise general awareness about the dangers and caveats of modifying system files in Big Sur, since I feel this doesn't really get highlighted enough. If not, you should definitely file abugabout that. I will look at this shortly, but I have a feeling that the hashes are inaccessible except by macOS. On Macs with Apple silicon SoCs, the SIP configuration is stored inside the LocalPolicy file - SIP is a subset of the security policy. That said, would you describe installing macOS the way I did with Catalina as redundant if my Mac has a T2 chip? I dont think you can enable FileVault on a snapshot: its a whole volume encryption surely. Thank you. 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. Show results from. Thank you hopefully that will solve the problems. A forum where Apple customers help each other with their products. 6. undo everything and enable authenticated root again.

Each to their own Every file on Big Surs System volume now has a SHA-256 cryptographic hash which is stored in the file system metadata. Sorry about that. For Macs without OpenCore Legacy Patcher, simply run csrutil disable and csrutil authenticated-root disable in RecoveryOS For hackintoshes, set csr-active-config to 030A0000 (0xA03) and ensure this is correctly applied You may use RecoveryOS instead however remember that NVRAM reset will wipe this var and require you to re-disable it It is already a read-only volume (in Catalina), only accessible from recovery! to turn cryptographic verification off, then mount the System volume and perform its modifications. It requires a modified kext for the fans to spin up properly. 1-800-MY-APPLE, or, https://support.apple.com/guide/mac-help/macos-recovery-a-mac-apple-silicon-mchl82829c17/mac, Sales and Howard.

SIP is locked as fully enabled. 1. - mkidr -p /Users//mnt mount the System volume for writing Youre now watching this thread and will receive emails when theres activity. This will be stored in nvram. Time Machine obviously works fine. Yeah, my bad, thats probably what I meant. To make that bootable again, you have to bless a new snapshot of the volume using a command such as But then again we have faster and slower antiviruses.. An how many in 100 users go in recovery, use terminal commands just to edit some config files ? Individual files have hashes, then those hashes have hashes, and so on up in a pyramid to reach the single master Seal at the top. Theres a world of difference between /Library and /System/Library!

The seal is verified each time your Mac starts up, by the boot loader before the kernel is loaded, and during installation and update of macOS system files. She has no patience for tech or fiddling. ( SSD/NVRAM ) Im rather surprised that your risk assessment concluded that it was worth disabling Big Surs primary system protection in order to address that, but each to their own. Im sorry, I dont know. If you dont trust Apple, then you really shouldnt be running macOS. Press Return or Enter on your keyboard. Howard. Follow these step by step instructions: reboot. A simple command line tool appropriately called 'dsenableroot' will quickly enable the root user account in Mac OS X. Encryption should be in a Volume Group. Apple has been tightening security within macOS for years now. Unfortunately I cant get past step 1; it tells me that authenticated root is an invalid command in recovery. Thank you. In T2 Macs, their internal SSD is encrypted. Its a good thing that Ive invested in two M1 Macs, and that the T2 was only a temporary measure along the way. Open Utilities Terminal and type csrutil disable Restart in Recovery Mode again and continue with Main Procedure Main Procedure Open Utilities Terminal and type mount A list of things will show up once you enter in (mount) in Terminal Write down the disk associated with /Volumes/Macintosh HD (mine was /dev/disk2s5) Or could I do it after blessing the snapshot and restarting normally? If the host machine natively has Catalina or older installed to its internal disk, its native Recovery Mode will not support the "csrutil authenticated-root" flag in Terminal. Thank you, and congratulations. I mean the hierarchy of hashes is being compared to some reference kept somewhere on the same state, right? (This did required an extra password at boot, but I didnt mind that). any proposed solutions on the community forums. One unexpected problem with unsealing at present is that FileVault has to be disabled, and cant be enabled afterwards. 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. It just requires a reboot to get the kext loaded. It is that simple. 5. change icons if your root is /dev/disk1s2s3, you'll mount /dev/disk1s2 Create a new directory, for example ~/ mount Run sudo mount -o nobrowse -t apfs DISK_PATH MOUNT_PATH, using the values from above Ever.

Once you've done that, you can then mount the volume in write mode to modify it and install GA, and then go on (crossing fingers) to bless it Code: Select all Expand view Well, privacy goes hand in hand with security, but should always be above, like any form of freedom. Well, would gladly use Catalina but there are so many bugs and the 16 MacBook Pro cant do Mojave (which would be perfect) since it is not supported . Search articles by subject, keyword or author. Customizing or disabling SIP will automatically downgrade the security policy to Permissive Security. 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. You may also boot to recovery and use Terminal to type the following commands: csrutil disable csrutil authenticated-root disable -> new in Big Sur.

To remove the symlink, try disabling SIP temporarily (which is most likely protecting the symlink on the Data volume). But I fathom that the M1 MacBook Pro arriving later this week might give it all a run for the money. Thank you. And when your system is compromised, what value was there in trying to stop Apple getting private data in the first place? If verification fails, startup is halted and the user prompted to re-install macOS before proceeding. Each runs the same test, and gets the same results, and it always puzzles me why several identical checks cant be combined into one, with each of those processes accessing the same result. [] those beta issues, changes in Big Surs security scheme for the System volume may cause headaches for some usersif nothing else, reverting to Catalina will require []. 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.
