An how many in 100 users go in recovery, use terminal commands just to edit some config files ? Howard, I am trying to do the same thing (have SSV disables but have FileVault enabled). Howard. % dsenableroot username = Paul user password: root password: verify root password: Hoping that option 2 is what we are looking at. If you wanted to run Mojave on your MBP, you only have to install Catalina and run it in a VM, which would surely give you even better protection. 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. Ill report back when Ive had a bit more of a look around it, hopefully later today. Thanks. Heres hoping I dont have to deal with that mess. Yes, completely. 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. Thank you. Do you know if theres any possibility to both have SIP (at least partially) disabled and keep the Security Policy on the Reduced level, so that I can run certain high-privileged utilities (such as yabai, a tiling window manager) while keeping the ability to run iOS apps? [] Big Surs Signed System Volume: added security protection eclecticlight.co/2020/06/25/big-surs-signed-system-volume-added-security-protection/ []. Mount root partition as writable comment enlever un mur de gypse hotels near lakewood, nj hotels near lakewood, nj not give them a chastity belt. You cant then reseal it. Those familiar with my file integrity tools will recognise that this is essentially the same technique employed by them. Time Machine obviously works fine. Thank you. that was also explicitly stated on the second sentence of my original post. What is left unclear to me as a basic user: if 1) SSV disabling tampers some hardware change to prevent signing ever again on that maching or 2) SSV can be re-enabled by reinstallation of the MacOS Big Sur.

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. Unfortunately I cant get past step 1; it tells me that authenticated root is an invalid command in recovery. https://developer.apple.com/documentation/kernel/installing_a_custom_kernel_extension, Custom kexts are linked into a file here: /Library/KernelCollections/AuxiliaryKernelExtensions.kc (which is not on the sealed system volume) Personal Computers move to the horrible iPhone model gradually where I cannot modify my private owned hardware on my own. Major thank you! Catalina 10.15 changes that by splitting the boot volume into two: the System and Data volumes, making up an APFS Volume Group. Thats quite a large tree! You'll need to keep SSV disabled (via "csrutil authenticated-root disable") forever if your root volume has been modified. cstutil: The OS environment does not allow changing security configuration options. Howard. My fully equipped MacBook Pro 2018 never quite measured up.IN fact, I still use an old 11 MacBook Air mid 2011 with upgraded disk and BLE for portable productivity not satisfied with an iPad. But Apple puts that seal there to warrant that its intact in accordance with Apples criteria. https://arstechnica.com/gadgets/2020/11/apple-lets-some-big-sur-network-traffic-bypass-firewalls/. e. Of course you can modify the system as much as you like. So the choices are no protection or all the protection with no in between that I can find. Id be inclined to perform a full restore using Configurator 2, which seems daunting but is actually very quick, less than 10 minutes. Certainly not Apple. Intriguing. When I try to change the Security Policy from Restore Mode, I always get this error: 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. It would seem silly to me to make all of SIP hinge on SSV. You can verify with "csrutil status" and with "csrutil authenticated-root status". 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. Yes, Im fully aware of the vulnerability of the T2, thank you. and how about updates ? sudo bless --folder /[mountpath]/System/Library/CoreServices --bootefi --create-snapshot to create the new snapshot and bless it If not, you should definitely file abugabout that. I suspect that quite a few are already doing that, and I know of no reports of problems. 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. 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. only. and they illuminate the many otherwise obscure and hidden corners of macOS. sudo bless --folder /[mountpath]/System/Library/CoreServices --bootefi --create-snapshot. I figured as much that Apple would end that possibility eventually and now they have. I also read somewhere that you could only disable SSV with FireVault off, but that definitely needs to stay on. csrutil authenticated root disable invalid commandverde independent obituaries. @JP, You say: So from a security standpoint, its just as safe as before? Why I am not able to reseal the volume? The main protections provided to the system come from classical Unix permissions with the addition of System Integrity Protection (SIP), software within macOS. But he knows the vagaries of Apple. csrutil authenticated-root disable as well. A forum where Apple customers help each other with their products. 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. Type at least three characters to start auto complete. As explained above, in order to do this you have to break the seal on the System volume. You can have complete confidence in Big Sur that nothing has nobbled whats on your System volume. Id be interested to hear some old Unix hands commenting on the similarities or differences. I think you should be directing these questions as JAMF and other sysadmins. Do so at your own risk, this is not specifically recommended. So for a tiny (if that) loss of privacy, you get a strong security protection. Ive been running a Vega FE as eGPU with my macbook pro. Thank you. Step 16: mounting the volume After reboot, open a new Terminal and: Mount your Big Sur system partition, not the data one: diskutil mount /Volumes/<Volume\ Name. But I could be wrong. How can I solve this problem? Thank you. Thank you. Disable System Integrity Protection with command: csrutil disable csrutil authenticated-root disable. So whose seal could that modified version of the system be compared against? Restart or shut down your Mac and while starting, press Command + R key combination. Im not sure what your argument with OCSP is, Im afraid. Don't forgot to enable the SIP after you have finished the job, either through the Startup Security Utility or the command "csrutil enable" in the Terminal. 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). Hello all, I was recently trying to disable the SIP on my Mac, and therefore went to recovery mode. The thing is, encrypting or making the /System read-only does not prevent malware, rogue apps or privacy invading programs. In any case, what about the login screen for all users (i.e. The OS environment does not allow changing security configuration options. On Macs with Apple silicon SoCs, the SIP configuration is stored inside the LocalPolicy file - SIP is a subset of the security policy. 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 Yeah, my bad, thats probably what I meant. This ensures those hashes cover the entire volume, its data and directory structure. I didnt know about FileVault, although in a T2 or M1 Mac the internal disk should still be encrypted as normal. Have you reported it to Apple as a bug? That is the big problem. Howard. [] APFS in macOS 11 changes volume roles substantially. Thanks for the reply! Ensure that the system was booted into Recovery OS via the standard user action. Thank you. 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". Not necessarily a volume group: a VG encrypts as a group, but volumes not in a group can of course be encrypted individually. As thats on the writable Data volume, there are no implications for the protection of the SSV. Click the Apple symbol in the Menu bar. ), that is no longer built into the prelinked kernel which is used to boot your system, instead being built into /Library/KernelCollections/AuxiliaryKernelExtensions.kc. Would it really be an issue to stay without cryptographic verification though? Howard. Incidentally, I just checked prices on an external 1 TB SSD and they can be had for under $150 US. Reboot the Mac and hold down Command + R keys simultaneously after you hear the startup chime, this will boot Mac OS X into Recovery Mode Thanks for your reply. Guys, theres no need to enter Recovery Mode and disable SIP or anything. I wish you the very best of luck youll need it! The bputil man page (in macOS, open Terminal, and search for bputil under the Help menu). In macOS Big Sur and later, your Mac boots from a cryptographically sealed snapshot. Id be interested to know in what respect you consider those or other parts of Big Sur break privacy. Great to hear! Its authenticated. SSV seems to be an evolution of that, similar in concept (if not of execution), sort of Tripwire on steroids. from the upper MENU select Terminal. Im sure there are good reasons why it cant be as simple, but its hardly efficient. -l Hopefully someone else will be able to answer that. would anyone have an idea what am i missing or doing wrong ? You may be fortunate to live in Y country that has X laws at the moment not all are in the same boat. a. `csrutil disable` command FAILED. Short answer: you really dont want to do that in Big Sur. If you dont trust Apple, then you really shouldnt be running macOS. 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. Maybe I can convince everyone to switch to Linux (more likely- Windows, since people wont give up their Adobe and MicroSoft products). Run csrutil authenticated-root disableto disable the authenticated root from the System Integrity Protection (SIP). Then I opened Terminal, and typed "csrutil disable", but the result was "csrutil: command not found". 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. 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. It is well-known that you wont be able to use anything which relies on FairPlay DRM. In the end, you either trust Apple or you dont. This will get you to Recovery mode. Therefore, I usually use my custom display profile to enable HiDPI support at 2560x1080, which requires access to /System/Library/Displays/Contents/Resources/Overrides/. Howard. Customizing or disabling SIP will automatically downgrade the security policy to Permissive Security. My OS version is macos Monterey12.0.1, and my device is MacBook Pro 14'' 2021. Looks like no ones replied in a while. call As mentioned by HW-Tech, Apple has added additional security restrictions for disabling System Integrity Protection (SIP) on Macs with Apple silicon. How you can do it ? 3. boot into OS Update: my suspicions were correct, mission success! Also, type "Y" and press enter if Terminal prompts for any acknowledgements. Well, I though the entire internet knows by now, but you can read about it here: Yes. [] (Via The Eclectic Light Company .) c. Keep default option and press next. See the security levels below for more info: Full Security: The default option, with no security downgrades permitted. Then reboot. Im not saying only Apple does it. While I dont agree with a lot of what Apple does, its the only large vendor that Ive never had any privacy problem with. Run the command "sudo. SuccessCommand not found2015 Late 2013 If you really feel the need or compulsion to modify files on the System volume, then perhaps youd be better sticking with Catalina? csrutil authenticated-root disable csrutil disable 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 . It looks like the hashes are going to be inaccessible. [] 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. But I wouldnt have thought thered be any fundamental barrier to enabling this on a per-folder basis, if Apple wanted to. I think this needs more testing, ideally on an internal disk. mount -uw /Volumes/Macintosh\ HD. Thank you. Encrypted APFS volumes are intended for general storage purposes, not for boot volumes. Its free, and the encryption-decryption handled automatically by the T2. You like where iOS is? 1. @hoakley With each release cycle I think that the days of my trusty Mac Pro 5,1 are done. 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). Running multiple VMs is a cinch on this beast. Now do the "csrutil disable" command in the Terminal. Howard. I have a 2020 MacBook Pro, and with Catalina, I formatted the internal SSD to APFS-encrypted, then I installed macOS, and then I also enabled FileVault.. In your specific example, what does that person do when their Mac/device is hacked by state security then? User profile for user: 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. It sleeps and does everything I need. Since FileVault2 is handled for the whole container using the T2 I suspect, it will still work. Its a neat system. Our Story; Our Chefs If your Mac has a corporate/school/etc. I hope so I ended up paying an arm and a leg for 4 x 2 TB SSDs for my backups, plus the case. Couldnt create snapshot on volume /Volumes/Macintosh HD: Operation not permitted, i have both csrutil and csrutil authenticated-root disabled. One unexpected problem with unsealing at present is that FileVault has to be disabled, and cant be enabled afterwards. 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. All you need do on a T2 Mac is turn FileVault on for the boot disk. It had not occurred to me that T2 encrypts the internal SSD by default. Theres no encryption stage its already encrypted. Mojave boot volume layout For some, running unsealed will be necessary, but the great majority of users shouldnt even consider it as an option. Im sorry, although Ive upgraded two T2 Macs, both were on the internal SSD which is encrypted anyway, and not APFS encrypted. What you are proposing making modifications to the system cannot result in the seal matching that specified by Apple. 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. Updates are also made more reliable through this mechanism: if they cant be completed, the previous system is restored using its snapshot. I mean the hierarchy of hashes is being compared to some reference kept somewhere on the same state, right? Putting privacy as more important than security is like building a house with no foundations. Youre now watching this thread and will receive emails when theres activity. Its not the encrypted APFS that you would use on external storage, but implemented in the T2 as disk controller. The merkle tree is a gzip compressed text file, and Big Sur beta 4 is here: https://github.com/rickmark/mojo_thor/blob/master/SSV/mtree.i.txt. If you really want to do that, then the basic requirements are outlined above, but youre out almost on your own in doing it, and will have lost two of your two major security protections. You drink and drive, well, you go to prison. Type csrutil disable. 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. At some point you just gotta learn to stop tinkering and let the system be. by | Jun 16, 2022 | kittens for sale huyton | aggregate jail sentence | Jun 16, 2022 | kittens for sale huyton | aggregate jail sentence In Catalina, making changes to the System volume isnt something to embark on without very good reason. You are using an out of date browser. Do you guys know how this can still be done so I can remove those unwanted apps ? Howard. The seal is verified against the value provided by Apple at every boot. 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). The SSV is very different in structure, because its like a Merkle tree. 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. SIP # csrutil status # csrutil authenticated-root status Disable Level 1 8 points `csrutil disable` command FAILED. No one forces you to buy Apple, do they? This site contains user submitted content, comments and opinions and is for informational purposes Youve stopped watching this thread and will no longer receive emails when theres activity. Can you re-enable the other parts of SIP that do not revolve around the cryptographic hashes? Nov 24, 2021 6:03 PM in response to agou-ops. In VMware option, go to File > New Virtual Machine. .. 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. Big Sur, however, will not allow me to install to an APFS-encrypted volume on the internal SSD, even after unlocking said volume, so its unclear whether thats a bug or design choice. csrutil authenticated-root disable Looking at the logs frequently, as I tend to do, there are plenty of inefficiencies apparent, but not in SIP and its related processes, oddly. Disable FileVault if enabled, boot into the Recovery Mode, launch Terminal, and issue the following (this is also known as "disabling SSV"): Boot back into macOS and issue the following: Navigate to the "mount" folder and make desired changes to system files (requires "sudo" privileges), then commit the changes via: Obviously, you need to take general precautions when modifying any system file, as it can break your installation (as has been true for as long as macOS itself has existed). 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? Apple owns the kernel and all its kexts. Here are the steps. 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. Unlike previous versions of macOS and OS X when one could turn off SIP from the regular login system using Opencore config.plist parameter NVRAM>Add>csr-active-config and then issue sudo spctl --master-disable to allow programs installation from Anywhere, with Big Sur one must boot into Recover OS to turn the Security off.. 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. 5. change icons Maybe when my M1 Macs arrive. Thank you yes, weve been discussing this with another posting. iv. The file resides in /[mountpath]/Library/Displays/Contents/Resources/Overrides therefore for Catalina I used Recovery Mode to edit those files. I was able to do this under Catalina with csrutil disable, and sudo mount -uw/ but as your article indicates this no longer works with Big Sur. Theres no way to re-seal an unsealed System. Thank you. I solved this problem by completely shutting down, then powering on, and finally restarting the computer to Recovery OS. I wouldn't expect csrutil authenticated-root disable to be safe or not safe, either way. Thank you. 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. I must admit I dont see the logic: Apple also provides multi-language support. 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.

However it did confuse me, too, that csrutil disable doesn't set what an end user would need. 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). Touchpad: Synaptics. Thank you. (I know I can change it for an individual user; in the past using ever-more-ridiculous methods Ive been able to change it for all users (including network users) OMG I just realized weve had to turn off SIP to enable JAMF to allow network users. One thing to note is that breaking the seal in this way seems to disable Apples FairPlay DRM, so you cant access anything protected with that until you have restored a sealed system. You do have a choice whether to buy Apple and run macOS. 4. Sounds like youd also be stuck on the same version of Big Sur if the delta updates arent able to verify the cryptographic information. But no apple did horrible job and didnt make this tool available for the end user. And when your system is compromised, what value was there in trying to stop Apple getting private data in the first place? Would you want most of that removed simply because you dont use it? In doing so, you make that choice to go without that security measure. But with its dual 3.06Ghz Xeons providing 12 cores, 48GB of ECC RAM, 40TB of HDD, 4TB of SSD, and 2TB of NVME disks all displayed via a flashed RX-580 on a big, wide screen, it is really hard to find something better.
