FYI, I found most enlightening. Certainly not Apple. Unfortunately I cant get past step 1; it tells me that authenticated root is an invalid command in recovery. Enabling FileVault doesnt actually change the encryption, but restricts access to those keys. Maybe I am wrong ? Theres a world of difference between /Library and /System/Library! Howard. I booted using the volume containing the snapshot (Big Sur Test for me) and tried enabling FIleVault which failed. Thank you. Couldnt create snapshot on volume /Volumes/Macintosh HD: Operation not permitted, i have both csrutil and csrutil authenticated-root disabled. But Apple puts that seal there to warrant that its intact in accordance with Apples criteria. I have more to come over changes in file security and protection on Apple Silicon, but theres nothing I can see about more general use of or access to file hashes, Im afraid. The seal is verified against the value provided by Apple at every boot. Our Story; Our Chefs 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. So I think the time is right for APFS-based Time Machine, based on the availability of reasonably-priced hardware for most users to support it. If not, you should definitely file abugabout that. This ensures those hashes cover the entire volume, its data and directory structure. molar enthalpy of combustion of methanol. To remove the symlink, try disabling SIP temporarily (which is most likely protecting the symlink on the Data volume). Thank you. csrutil enable prevents booting. Also, you might want to read these documents if you're interested. On Macs with Apple silicon SoCs, the SIP configuration is stored inside the LocalPolicy file - SIP is a subset of the security policy. In your specific example, what does that person do when their Mac/device is hacked by state security then? You probably wont be able to install a delta update and expect that to reseal the system either. Im not sure what your argument with OCSP is, Im afraid. Howard. My MacBook Air is also freezing every day or 2. Heres hoping I dont have to deal with that mess. Since Im the only one making changes to the filesystem (and, of course, I am not installing any malware manually), wouldnt I be able to fully trust the changes that I made? Howard. Howard. The OS environment does not allow changing security configuration options. Why do you need to modify the root volume? In addition, you can boot a custom kernel (the Asahi Linux team is using this to allow booting Linux in the future). When you boot a Mac that has SSV enabled, there's really no explicit error seen during a signature failure. Any suggestion? Thank you. Thanks for your reply. Press Return or Enter on your keyboard. From a security standpoint, youre removing part of the primary protection which macOS 11 provides to its system files, when you turn this off thats why Apple has implemented it, to improve on the protection in 10.15. This crypto volume crap is definitely a mouth gag for the power USER, not hackers, or malware. only. Howard. Am I right in thinking that once you disable authenticated-root, you cannot enable it if youve made changes to the system volume? If you cant trust it to do that, then Linux (or similar) is the only rational choice. For without ensuring rock-solid security as the basis for protecting privacy, it becomes all too easy to bypass everything. Thank you I have corrected that now. For a better experience, please enable JavaScript in your browser before proceeding. Apple doesnt keep any of the files which need to be mutable in the sealed System volume anyway and put significant engineering effort into ensuring that using firmlinks. csrutil authenticated-root disable csrutil disable macOS mount <DISK_PATH> 1 2 $ mount /dev/disk1s5s1 on / (apfs, sealed, local, read-only, journaled) / /dev/disk1s5s1 /dev/disk1s5s1 "Snapshot 1"APFS <MOUNT_PATH> ~/mount 1 mkdir -p -m777 ~/mount 1 Configuring System Integrity Protection System Integrity Protection Guide Table of Contents Introduction File System Protections Runtime Protections Kernel Extensions Configuring System Integrity Protection Revision History Very helpful Somewhat helpful Not helpful Yes. You drink and drive, well, you go to prison. Do so at your own risk, this is not specifically recommended. Mojave boot volume layout Increased protection for the system is an essential step in securing macOS. Howard. Thank you. Thank you. One unexpected problem with unsealing at present is that FileVault has to be disabled, and cant be enabled afterwards. if your root is/dev/disk1s2s3, you'll mount/dev/disk1s2, Create a new directory, for example~/mount, Runsudo mount -o nobrowse -t apfs DISK_PATH MOUNT_PATH, using the values from above, Modify the files under the mounted directory, Runsudo bless --folder MOUNT_PATH/System/Library/CoreServices --bootefi --create-snapshot, Reboot your system, and the changes will take place, sudo mount -o nobrowse -t afps /dev/disk1s5 ~/mount, mount: exec /Library/Filesystems/afps.fs/Contents/Resources/mount_afps for /Users/user/mount: No such file or directory. I think this needs more testing, ideally on an internal disk. Mount root partition as writable Restart your Mac and go to your normal macOS. When I try to change the Security Policy from Restore Mode, I always get this error: During the prerequisites, you created a new user and added that user . All good cloning software should cope with this just fine. But then again we have faster and slower antiviruses.. https://github.com/barrykn/big-sur-micropatcher. 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). csrutil disable csrutil authenticated-root disable # Big Sur+ Reboot, and SIP will have been adjusted accordingly. csrutil authenticated-root disable csrutil disable This will be stored in nvram. Howard. Im guessing theres no TM2 on APFS, at least this year. So yes, I have to stick with it for a long time now, knowing it is not secure (and never will be), to make it more secure I have to sacrifice privacy, and it will look like my phone lol. In the end, you either trust Apple or you dont. In Recovery mode, open Terminal application from Utilities in the top menu. you will be in the Recovery mode. You can checkout the man page for kmutil or kernelmanagerd to learn more . The best explanation I've got is that it was never really intended as an end user tool, and so that, as it's currently written, to get a non-Apple internal setting . It sounds like Apple may be going even further with Monterey. Normally, you should be able to install a recent kext in the Finder. It just requires a reboot to get the kext loaded. Not necessarily a volume group: a VG encrypts as a group, but volumes not in a group can of course be encrypted individually. Howard. Select "Custom (advanced)" and press "Next" to go on next page. VM Configuration. But no apple did horrible job and didnt make this tool available for the end user. That seems like a bug, or at least an engineering mistake. Here are the steps. It effectively bumps you back to Catalina security levels. Thats the command given with early betas it may have changed now. Im not saying only Apple does it. If you were to make and bless your own snapshot to boot from, essentially disabling SSV from my understanding, is all of SIP then disabled on that snapshot or just SSV? My machine is a 2019 MacBook Pro 15. Also, any details on how/where the hashes are stored? Looks like there is now no way to change that? 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? Thank you. Press Esc to cancel. Every security measure has its penalties. I solved this problem by completely shutting down, then powering on, and finally restarting the computer to Recovery OS. . To do this, once again you need to boot the system from the recovering partition and type this command: csrutil authenticated-root disable . That leaves your System volume without cryptographic verification, of course, and whether it will then successfully update in future must be an open question. That said, you won't be able to change SIP settings in Startup Security Utility, because the Permissive Security option isn't available in Startup Security Utility. mount the System volume for writing ). im trying to modify root partition from recovery. I think youll find that if you turn off or disable all macOS platform security, starting an app will get even faster, and malware will also load much more quickly too. Updates are also made more reliable through this mechanism: if they cant be completed, the previous system is restored using its snapshot. 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. To disable System Integrity Protection, run the following command: csrutil disable If you decide you want to enable SIP later, return to the recovery environment and run the following command: csrutil enable Restart your Mac and your new System Integrity Protection setting will take effect. Apples Develop article. To start the conversation again, simply Ah, thats old news, thank you, and not even Patricks original article. my problem is that i cannot seem to be able to bless the partition, apparently: -bash-3.2# bless mount /Volumes/Macintosh\ HD bootefi create-snapshot Apple disclaims any and all liability for the acts, omissions and conduct of any third parties in connection with or related to your use of the site. Whatever you use to do that needs to preserve all the hashes and seal, or the volume wont be bootable. Click the Apple symbol in the Menu bar. i drink every night to fall asleep. This command disables volume encryption, "mounts" the system volume and makes the change. Running multiple VMs is a cinch on this beast. Story. Mac added Signed System Volume (SSV) after Big Sur, you can disable it in recovery mode using follow command csrutil authenticated-root disable if SSV enabled, it will check file signature when boot system, and will refuse boot if you do any modify, also will cause create snapshot failed this article describe it in detail Would you want most of that removed simply because you dont use it? Yes, I remember Tripwire, and think that at one time I used it. Howard. I keep a macbook for 8years, and I just got a 16 MBP with a T2 it was 3750 EUR in a country where the average salary is 488eur. Although I havent tried it myself yet, my understanding is that disabling the seal doesnt prevent sealing any fresh installation of macOS at a later date. Hey Im trying to create the new snapshot because my Mac Pro (Mid 2014) has the issue where it randomly shutdown because of an issue with the AppleThunderboltNHI.kext found in /Volumes/Macintosh\ HD/System/Library/Extensions. 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 ? Reinstallation is then supposed to restore a sealed system again. SSV seems to be an evolution of that, similar in concept (if not of execution), sort of Tripwire on steroids. You'll need to keep SSV disabled (via "csrutil authenticated-root disable") forever if your root volume has been modified. lagos lockdown news today; csrutil authenticated root disable invalid command twitter wsdot. In Release 0.6 and Big Sur beta x ( i dont remember) i can installed Big Sur but keyboard not working (A). This will create a Snapshot disk then install /System/Library/Extensions/ GeForce.kext 1. disable authenticated root Of course there were and are apps in the App Store which exfiltrate (not just leak, which implies its accidental) sensitive information, but thats totally different. Its up to the user to strike the balance. Nov 24, 2021 4:27 PM in response to agou-ops. Thank you hopefully that will solve the problems. All postings and use of the content on this site are subject to the. It is well-known that you wont be able to use anything which relies on FairPlay DRM. It is dead quiet and has been just there for eight years. Without in-depth and robust security, efforts to achieve privacy are doomed. SIP is locked as fully enabled. Re-enabling FileVault on a different partition has no effect, Trying to enable FileVault on the snapshot fails with an internal error, Enabling csrutil also enables csrutil authenticated-root, The snapshot fails to boot with either csrutil or csrutil authenticated-root enabled. This workflow is very logical. And your password is then added security for that encryption. gpc program process steps . Howard. Big Sur really isnt intended to be used unsealed, which in any case breaks one of its major improvements in security. 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 Thank you, and congratulations. Howard. Thankfully, with recent Macs I dont have to engaged in all that fragile tinkering. You need to disable it to view the directory. 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)
