As I dont spend all day opening apps, that overhead is vanishingly small for me, and the benefits very much greater. Hi, Customizing or disabling SIP will automatically downgrade the security policy to Permissive Security. All good cloning software should cope with this just fine. I didnt know about FileVault, although in a T2 or M1 Mac the internal disk should still be encrypted as normal. im able to remount read/write the system disk and modify the filesystem from there, but all the things i do are gone upon reboot.

You drink and drive, well, you go to prison. Any suggestion? There are certain parts on the Data volume that are protected by SIP, such as Safari. That said, would you describe installing macOS the way I did with Catalina as redundant if my Mac has a T2 chip? Howard. CAUTION: For users relying on OpenCore's ApECID feature , please be aware this must be disabled to use the KDK. But beyond that, if something were to go wrong in step 3 when you bless the folder and create a snapshot, you could also end up with an non-bootable system. If you dont trust Apple, then you really shouldnt be running macOS. Since FileVault2 is handled for the whole container using the T2 I suspect, it will still work. only. Thank you, and congratulations. Now do the "csrutil disable" command in the Terminal. I don't know why but from beta 6 I'm not anymore able to load from that path at boot..) 4- mount / in read/write (-uw) When Authenticated Root is enabled the macOS is booted from a signed volume that is cryptographically protected to prevent tampering with the system volume. And putting it out of reach of anyone able to obtain root is a major improvement. But no apple did horrible job and didnt make this tool available for the end user. Nov 24, 2021 4:27 PM in response to agou-ops. Mojave boot volume layout So for a tiny (if that) loss of privacy, you get a strong security protection. A good example is OCSP revocation checking, which many people got very upset about.

I tried multiple times typing csrutil, but it simply wouldn't work. Would you want most of that removed simply because you dont use it? These options are also available: Permissive Security: All of the options permitted by Reduced Security are also permitted here. Click Restart If you later want to start using SIP once again (and you really should), then follow these steps again, except this time you'll enter csrutil enable in the Terminal instead. (Also, Ive scoured all the WWDC reports I could find and havent seen any mention of Time Machine in regards to Big Sur. What definitely does get much more complex is altering anything on the SSV, because you cant simply boot your Mac from a live System volume any more: that will fail these new checks. Begin typing your search above and press return to search. Howard, I am trying to do the same thing (have SSV disables but have FileVault enabled).

That makes it incredibly difficult for an attacker to hijack your Big Sur install, but it has [], I installed Big Sur last Tuesday when it got released to the public but I ran into a problem. System Integrity Protection (SIP) and the Security Policy (LocalPolicy) are not the same thing. It had not occurred to me that T2 encrypts the internal SSD by default. Thank you. 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. Encrypted APFS volumes are intended for general storage purposes, not for boot volumes. FYI, I found most enlightening. Thanks for anyone who could point me in the right direction! Thank you. (This did required an extra password at boot, but I didnt mind that). In Config.plist go to Gui section (in CC Global it is in the LEFT column 7th from the top) and look in the Hide Volume section ( Top Right in CCG) and Unhide the Recovery if you have hidden Recovery Partition (I always hide Recovery to reduce the clutter in Clover Boot Menu screen). Howard. In any case, what about the login screen for all users (i.e. and seal it again. You can verify with "csrutil status" and with "csrutil authenticated-root status". Howard. I think this needs more testing, ideally on an internal disk. Howard. REBOOTto the bootable USBdrive of macOS Big Sur, once more. 3. boot into OS and disable authenticated-root: csrutil authenticated-root disable. Apple disclaims any and all liability for the acts, Thank you for the informative post. To remove the symlink, try disabling SIP temporarily (which is most likely protecting the symlink on the Data volume). molar enthalpy of combustion of methanol. Type at least three characters to start auto complete. The only difference is that with a non-T2 Mac the encryption will be done behind the scenes after enabling FileVault. Disabling SSV on the internal disk worked, but FileVault cant be reenabled as it seems. Mount root partition as writable For the great majority of users, all this should be transparent. Whatever you use to do that needs to preserve all the hashes and seal, or the volume wont be bootable. Immutable system files now reside on the System volume, which not only has complete protection by SIP, but is normally mounted read-only. a. 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. In your specific example, what does that person do when their Mac/device is hacked by state security then? But I'm already in Recovery OS. Looks like no ones replied in a while. csrutil disable csrutil authenticated-root disable # Big Sur+ Reboot, and SIP will have been adjusted accordingly. You need to disable it to view the directory. ). It shouldnt make any difference. This makes it far tougher for malware, which not only has to get past SIP but to mount the System volume as writable before it can tamper with system files. It may not display this or other websites correctly. Every security measure has its penalties. Sounds like youd also be stuck on the same version of Big Sur if the delta updates arent able to verify the cryptographic information. Id be interested to hear some old Unix hands commenting on the similarities or differences. Just reporting a finding from today that disabling SIP speeds-up launching of apps 2-3 times versus SIP enabled!!! csrutil authenticated-root disable Allow MDM to manage kernel extensions and software updates, Disable Kernel Integrity Protection (disable CTRR), Disable Signed System Volume verification, Allow all boot arguments (including Single User Mode).

Im trying to implement the snapshot but you cant run the sudo bless folder /Volumes/Macintosh\ HD/System/Library/CoreServices bootefi create-snapshot in Recovery mode because sudo command is not available in recovery mode. You can have complete confidence in Big Sur that nothing has nobbled whats on your System volume. I dont think youd want to do it on a whole read-write volume, like the Data volume: you can get away with this on the System volume because theres so little writing involved, so the hashes remain static almost all the time. Id like to modify the volume, get rid of some processes who bypasses the firewalls (like Little Snitch read their blog!) macOS 12.0. Just be careful that some apps that automate macOS disk cloning and whatnot are not designed to handle the concept of SSV yet and will therefore not be bootable if SSV is enabled. Before explaining what is happening in macOS 11 Big Sur, Ill recap what has happened so far. However, it very seldom does at WWDC, as thats not so much a developer thing. `csrutil disable` command FAILED. How can I solve this problem? Then reboot. But I could be wrong. Why do you need to modify the root volume? Type csrutil disable. Unfortunately I cant get past step 1; it tells me that authenticated root is an invalid command in recovery. 3. csrutil authenticated-root disable Reboot back into MacOS Find your root mount's device - run mount and chop off the last s, e.g. Run "csrutil clear" to clear the configuration, then "reboot". Howard. I suspect that youd need to use the full installer for the new version, then unseal that again. Without in-depth and robust security, efforts to achieve privacy are doomed. This command disables volume encryption, "mounts" the system volume and makes the change. Just great. Thus no user can re-seal a system, only an Apple installer/updater, or its asr tool working from a sealed clone of the system. 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 looks like the hashes are going to be inaccessible. Ive seen many posts and comments with people struggling to bypass both Catalinas and Big Surs security to install an EDID override in order to force the OS recognise their screens as RGB.

Authenticated Root _MUST_ be enabled. I dont think its novel by any means, but extremely ingenious, and I havent heard of its use in any other OS to protect the system files. Does the equivalent path in/Librarywork for this? Another update: just use this fork which uses /Libary instead. But I fathom that the M1 MacBook Pro arriving later this week might give it all a run for the money.

Most probable reason is the system integrity protection (SIP) - csrutil is the command line utility. One major benefit to the user is that damaged system installs and updates are no longer possible, as they break the seal. Tampering with the SSV is a serious undertaking and not only breaks the seal which can never then be resealed but it appears to conflict with FileVault encryption too. Great to hear! These are very early days with the SSV, and I think well learn the rules and wrinkles in the coming weeks. Show results from. Thank you. During the prerequisites, you created a new user and added that user . Have you contacted the support desk for your eGPU? 4. mount the read-only system volume Catalina boot volume layout 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. Sure. westerly kitchen discount code csrutil authenticated root disable invalid command 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 captured in an electronic forum and Apple can therefore provide no guarantee as to the efficacy of Is that with 11.0.1 release? .. come one, I was running Dr.Unarhiver (from TrendMicro) for months, AppStore App, with all certificates and was leaking private info until Apple banned it. This is because, unlike the T2 chip, the M1 manages security policy per bootable OS. 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. Available in Startup Security Utility. 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 after all SSV is just a TOOL for me, to be sure about the volume integrity. Why choose to buy computers and operating systems from a vendor you dont feel you can trust? If that cant be done, then you may be better off remaining in Catalina for the time being. @hoakley With each release cycle I think that the days of my trusty Mac Pro 5,1 are done. Thank you. csrutil authenticated root disable invalid command. At some point you just gotta learn to stop tinkering and let the system be. If you really feel the need or compulsion to modify files on the System volume, then perhaps youd be better sticking with Catalina? The main protections provided to the system come from classical Unix permissions with the addition of System Integrity Protection (SIP), software within macOS. In Release 0.6 and Big Sur beta x ( i dont remember) i can installed Big Sur but keyboard not working (A). I wish you success with it. As Apples security engineers know exactly how that is achieved, they obviously understand how it is exploitable. enrollment profile that requires FileVault being enabled at all times, this can lead to even more of a headache. Guys, theres no need to enter Recovery Mode and disable SIP or anything. OCSP? Yes, Im fully aware of the vulnerability of the T2, thank you. On my old macbook, I created a symbolic link named "X11" under /usr to run XQuartz and forgot to remove the link with it later.

So whose seal could that modified version of the system be compared against? To make that bootable again, you have to bless a new snapshot of the volume using a command such as The file resides in /[mountpath]/Library/Displays/Contents/Resources/Overrides therefore for Catalina I used Recovery Mode to edit those files. . I do have to ditch authenticated root to enable the continuity flag for my MB, but thats it. Im not sure what your argument with OCSP is, Im afraid.

Well, I though the entire internet knows by now, but you can read about it here: 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 Thank you. Every file on Big Surs System volume now has a SHA-256 cryptographic hash which is stored in the file system metadata.. Not necessarily a volume group: a VG encrypts as a group, but volumes not in a group can of course be encrypted individually. would anyone have an idea what am i missing or doing wrong ? For years I reflexively replaced the Mail apps unappealing postage stamp icon with a simple, old-fashioned, eye-catching mailbox it just seemed to make visual sense to me but with all the security baked into recent incarnations of macOS, I would never attempt that now. (ex: /System/Library/Frameworks/NetworkExtension.framework/Versions/A/Resources/Info.plist). 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) Dont do anything about encryption at installation, just enable FileVault afterwards. Also, you might want to read these documents if you're interested. Update: my suspicions were correct, mission success! At it's most simple form, simply type 'dsenableroot' into the Terminal prompt, enter the users password, then enter and verify a root user password. Assuming Apple doesnt remove that functionality before release then that implies more efficient (and hopefully more reliable) TM backups. Further details on kernel extensions are here. The System volume within a boot Volume Group is now sealed using a tree of cryptographic hashes, as I have detailed here. 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). Time Machine obviously works fine. Can you re-enable the other parts of SIP that do not revolve around the cryptographic hashes? Please how do I fix this? Id be interested to know in what respect you consider those or other parts of Big Sur break privacy. I wouldn't expect csrutil authenticated-root disable to be safe or not safe, either way. You are using an out of date browser. OC Recover [](dmg)csrutil disablecsrutil authenticated-root disableMac RevocerMacOS modify the icons Very few people have experience of doing this with Big Sur. Its not the encrypted APFS that you would use on external storage, but implemented in the T2 as disk controller. Hello all, I was recently trying to disable the SIP on my Mac, and therefore went to recovery mode. As a warranty of system integrity that alone is a valuable advance. Ive installed Big Sur on a test volume and Ive booted into recovery to run csrutil authenticated-root disable but it seems that FileVault needs to be disabled on original Macintosh HD as well, which I find strange. [] FF0F0000-macOS Big Sur0xfffroot [], Found where the merkle tree is stored in img4 files: This is Big Sur Beta 4s mtree = https://github.com/rickmark/mojo_thor/blob/master/SSV/mtree.i.txt, Looks like the mtree and root_hash are stored in im4p (img4 payload) files in the preboot volume. In macOS Big Sur and later, your Mac boots from a cryptographically sealed snapshot. You have to assume responsibility, like everywhere in life. This crypto volume crap is definitely a mouth gag for the power USER, not hackers, or malware. Howard. cstutil: The OS environment does not allow changing security configuration options. Full disk encryption is about both security and privacy of your boot disk.
