Im sorry, although Ive upgraded two T2 Macs, both were on the internal SSD which is encrypted anyway, and not APFS encrypted. 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. If your Mac has a corporate/school/etc. So when the system is sealed by default it has original binary image that is bit-to-bit equal to the reference seal kept somewhere in the system. 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. . Please post your bug number, just for the record. Now do the "csrutil disable" command in the Terminal. It sounds like Apple may be going even further with Monterey. I also expect that you will be able to install a delta update to an unsealed system, leaving it updated but unsealed. 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. Hopefully someone else will be able to answer that. 5. change icons @hoakley With each release cycle I think that the days of my trusty Mac Pro 5,1 are done. I have rebooted directly into Recovery OS several times before instead of shutting down completely., Nov 24, 2021 6:23 PM in response to Encryptor5000, Dec 2, 2021 8:43 AM in response to agou-ops. Solved it by, at startup, hold down the option key, , until you can choose what to boot from and then click on the recovery one, should be Recovery-"version". In the same time calling for a SIP performance fix that could help it run more efficiently, When we all start calling SIP its real name antivirus/antimalvare and not just blocker of accessing certain system folders we can acknowledge performance hit. Its very visible esp after the boot. Did you mount the volume for write access? But I fathom that the M1 MacBook Pro arriving later this week might give it all a run for the money. Im sure that well see bug fixes, but whether it will support backups on APFS volumes I rather doubt. Thank you. In your case, that probably doesnt help you run highly privileged utilities, but theyre not really consistent with Mac security over the last few years. SIP I understand is hugely important, and I would not dream of leaving it disabled, but SSV seems overkill for my use. 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. 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 strickland funeral home pooler, ga; richest instagram influencers non celebrity; mtg bees deck; business for sale st maarten Also, type "Y" and press enter if Terminal prompts for any acknowledgements.

Does the equivalent path in/Librarywork for this? macOS 12.0. restart in normal mode, if youre lucky and everything worked. Refunds. The root volume is now a cryptographically sealed apfs snapshot. []. Am I reading too much into that to think there *might* be hope for Apple supporting general user file integrity at some point in the future? Press Esc to cancel. https://apple.stackexchange.com/questions/410430/modify-root-filesystem-from-recovery. However, even an unsealed Big Sur system is more secure than that in Catalina, as its actually a mounted snapshot, and not even the System volume itself. Im sure there are good reasons why it cant be as simple, but its hardly efficient. The last two major releases of macOS have brought rapid evolution in the protection of their system files. Thank you. You'll need to keep SSV disabled (via "csrutil authenticated-root disable") forever if your root volume has been modified. 4. mount the read-only system volume Would this have anything to do with the fact that I cant seem to install Big Sur to an APFS-encrypted volume like I did with Catalina? [] Big Sur further secures the System volume by applying a cryptographic hash to every file on it, as Howard Oakley explains. But I could be wrong. Tell a Syrian gay dude what is more important for him, some malware wiping his disk full of pictures and some docs or the websites visited and Messages sent to gay people he will be arrested and even executed. The file resides in /[mountpath]/Library/Displays/Contents/Resources/Overrides therefore for Catalina I used Recovery Mode to edit those files. You may be fortunate to live in Y country that has X laws at the moment not all are in the same boat. Theres a world of difference between /Library and /System/Library! Howard. I think Id stick with the default icons! The main protections provided to the system come from classical Unix permissions with the addition of System Integrity Protection (SIP), software within macOS. My OS version is macos Monterey12.0.1, and my device is MacBook Pro 14'' 2021. Authenticated Root _MUST_ be enabled. By the way, T2 is now officially broken without the possibility of an Apple patch Couldnt create snapshot on volume /Volumes/Macintosh HD: Operation not permitted, i have both csrutil and csrutil authenticated-root disabled. Heres hoping I dont have to deal with that mess. It requires a modified kext for the fans to spin up properly. Thank you. In macOS Big Sur and later, your Mac boots from a cryptographically sealed snapshot. I dont think you can enable FileVault on a snapshot: its a whole volume encryption surely. What you are proposing making modifications to the system cannot result in the seal matching that specified by Apple. However, you can always install the new version of Big Sur and leave it sealed. Increased protection for the system is an essential step in securing macOS. 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. It is dead quiet and has been just there for eight years. Because of this, the symlink in the usr folder must reside on the Data volume, and thus be located at: /System/Volumes/Data/usr. Howard. 1-800-MY-APPLE, or, https://support.apple.com/guide/mac-help/macos-recovery-a-mac-apple-silicon-mchl82829c17/mac, Sales and 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 Incidentally, I am in total sympathy with the person who wants to change the icons of native apps. disabled SIP ( csrutil disable) rebooted mounted the root volume ( sudo mount -o nobrowse -t apfs /dev/disk1s1 /Users/user/Mount) replaced files in /Users/user/Mount created a snapshot ( sudo bless --folder /Users/user/Mount/System/Library/CoreServices --bootefi --create-snapshot) rebooted (with SIP still disabled) To view your status you need to: csrutil status To disable it (which is usually a bad idea): csrutil disable (then you will probably need to reboot). CAUTION: For users relying on OpenCore's ApECID feature , please be aware this must be disabled to use the KDK. Can you re-enable the other parts of SIP that do not revolve around the cryptographic hashes? 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.

Each to their own Anyway, people need to learn, tot to become dumber thinking someone else has their back and they can stay dumb. 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. 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. after all SSV is just a TOOL for me, to be sure about the volume integrity. Thanks for the reply! The error is: cstutil: The OS environment does not allow changing security configuration options. The thing is, encrypting or making the /System read-only does not prevent malware, rogue apps or privacy invading programs. If anyone finds a way to enable FileVault while having SSV disables please let me know. If you choose to modify the system, you cant reseal that, but you can run Big Sur perfectly well without a seal. 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 Apple: csrutil disable "command not found"Helpful? 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. Just great. This to me is a violation. Therefore, you'll need to force it to boot into the external drive's Recovery Mode by holding "option" at boot, selecting the external disk that has Big Sur, and then immediately hitting "command + r" in just the right timing to load Big Sur's Recovery Mode. I input the root password, well, I should be able to do whatever I want, wipe the disk or whatever. That isnt the case on Macs without a T2 chip, though, where you have to opt to turn FileVault on or off. At some point you just gotta learn to stop tinkering and let the system be. The only choice you have is whether to add your own password to strengthen its encryption. In Recovery mode, open Terminal application from Utilities in the top menu. Search. There are certain parts on the Data volume that are protected by SIP, such as Safari. Same issue as you on my MacOS Monterey 12.0.1, Mackbook Pro 2021 with M1 Pro. Howard. Howard. This allows the boot disk to be unlocked at login with your password and, in emergency, to be unlocked with a 24 character recovery code. How can I solve this problem? 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 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. This is because the SIP configuration is stored directly in the Security Policy (aka the LocalPolicy). 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 When a user unseals the volume, edit files, the hash hierarchy should be re-hashed and the seal should to be accepted (effectively overwritng the (old) reference) Paste the following command into the terminal then hit return: csrutil disable; reboot You'll see a message saying that System Integrity Protection has been disabled, and the Mac needs to restart for changes to take effect. Most probable reason is the system integrity protection (SIP) - csrutil is the command line utility. 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. 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. I like things to run fast, really fast, so using VMs is not an option (I use them for testing). As mentioned by HW-Tech, Apple has added additional security restrictions for disabling System Integrity Protection (SIP) on Macs with Apple silicon. I booted using the volume containing the snapshot (Big Sur Test for me) and tried enabling FIleVault which failed. If I didnt trust Apple, then I wouldnt do business with them, nor develop software for macOS. i thank you for that ..allow me a small poke at humor: just be sure to read the question fully , Im a mac lab manager and would like to change the login screen, which is a file on the now-even-more-protected system volume (/System/Library/Desktop Pictures/Big Sur Graphic.heic). i made a post on apple.stackexchange.com here: You probably wont be able to install a delta update and expect that to reseal the system either.

I essentially want to know how many levels of protection you can retain after making a change to the System folder if that helps clear it up. That is the big problem. But then again we have faster and slower antiviruses.. It may appear impregnable in Catalina, but mounting it writeable is not only possible but something every Apple updater does without going into Recovery mode. https://arstechnica.com/gadgets/2020/11/apple-lets-some-big-sur-network-traffic-bypass-firewalls/. Howard. 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. only.

Intriguingly, I didnt actually changed the Permissive Security Policy myself at all it seems that executing `csrutil disable` has the side effect of reduce the policy level to Permissive, and tuning the policy level up to Reduced or Full also force re-enabling SIP. One of the fundamental requirements for the effective protection of private information is a high level of security. The MacBook has never done that on Crapolina. To make that bootable again, you have to bless a new snapshot of the volume using a command such as sudo bless --folder / [mountpath]/System/Library/CoreServices --bootefi --create-snapshot 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. Those familiar with my file integrity tools will recognise that this is essentially the same technique employed by them. I suspect that quite a few are already doing that, and I know of no reports of problems. These options are also available: To modify or disable SIP, use the csrutil command-line tool. Thank you, and congratulations. Howard. network users)? @JP, You say: Howard. Mount root partition as writable Could you elaborate on the internal SSD being encrypted anyway?

SSV seems to be an evolution of that, similar in concept (if not of execution), sort of Tripwire on steroids. csrutil enable prevents booting. Hello, you say that you can work fine with an unsealed volume, but I also see that for example, breaking the seal prevents you from turning FileVault ON. 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. and how about updates ? In T2 Macs, their internal SSD is encrypted. Im sorry I dont know. Assuming you have entered the Recovery mode already, by holding down the Power button when powering-up/rebooting. Always. Howard.

The detail in the document is a bit beyond me! Intriguing. Dont do anything about encryption at installation, just enable FileVault afterwards. In Big Sur, it becomes a last resort. A forum where Apple customers help each other with their products. In Mojave, all malware has to do is exploit a vulnerability in SIP, gain elevated privileges, and it can do pretty well what it likes with system files. I mean the hierarchy of hashes is being compared to some reference kept somewhere on the same state, right? A good example is OCSP revocation checking, which many people got very upset about. Well, I though the entire internet knows by now, but you can read about it here: A simple command line tool appropriately called 'dsenableroot' will quickly enable the root user account in Mac OS X.
