3. I have tried to avoid this by executing `csrutil disable` with flags such as `with kext with dtrace with nvram with basesystem` and re-enable Authenticated Root Requirement with the `authenticated-root` sub-command you mentioned in the post; all resulted in vain. Howard. No need to disable SIP. SIP is locked as fully enabled. One unexpected problem with unsealing at present is that FileVault has to be disabled, and cant be enabled afterwards. csrutil disable csrutil authenticated-root disable # Big Sur+ Reboot, and SIP will have been adjusted accordingly. There are certain parts on the Data volume that are protected by SIP, such as Safari. Longer answer: the command has a hyphen as given above. [].

You install macOS updates just the same, and your Mac starts up just like it used to. 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. You do have a choice whether to buy Apple and run macOS. It just requires a reboot to get the kext loaded. Howard. Id like to modify the volume, get rid of some processes who bypasses the firewalls (like Little Snitch read their blog!) The Mac will then reboot itself automatically. The SSV is very different in structure, because its like a Merkle tree. Trust me: you really dont want to do this in Big Sur. And when your system is compromised, what value was there in trying to stop Apple getting private data in the first place? Thank you. Can you re-enable the other parts of SIP that do not revolve around the cryptographic hashes? Thank you, and congratulations. sudo bless --folder /[mountpath]/System/Library/CoreServices --bootefi --create-snapshot to create the new snapshot and bless it I have now corrected this and my previous article accordingly. Thank you. It sleeps and does everything I need. Its up to the user to strike the balance. a. Im sorry, I dont know. Thank you so much for that: I misread that article! I wouldn't expect csrutil authenticated-root disable to be safe or not safe, either way. Before explaining what is happening in macOS 11 Big Sur, Ill recap what has happened so far. Running multiple VMs is a cinch on this beast. 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. (Also, Ive scoured all the WWDC reports I could find and havent seen any mention of Time Machine in regards to Big Sur. Increased protection for the system is an essential step in securing macOS. as you hear the Apple Chime press COMMAND+R. ask a new question. 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. 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. Howard. 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. 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. Disabling SSV requires that you disable FileVault. Update: my suspicions were correct, mission success! 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. 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 . csrutil enable prevents booting. I do have to ditch authenticated root to enable the continuity flag for my MB, but thats it. Thank you. That leaves your System volume without cryptographic verification, of course, and whether it will then successfully update in future must be an open question. 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). Did you mount the volume for write access? . During the prerequisites, you created a new user and added that user . You probably wont be able to install a delta update and expect that to reseal the system either. They have more details on how the Secure Boot architecture works: Nov 24, 2021 5:24 PM in response to agou-ops, Nov 24, 2021 5:45 PM in response to Encryptor5000. Am I out of luck in the future? Another update: just use this fork which uses /Libary instead. Every single bit of the fsroot tree and file contents are verified when they are read from disk."

SIP # csrutil status # csrutil authenticated-root status Disable and seal it again. Thats quite a large tree! Since FileVault2 is handled for the whole container using the T2 I suspect, it will still work. Have you reported it to Apple as a bug? If I didnt trust Apple, then I wouldnt do business with them, nor develop software for macOS. 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). The MacBook has never done that on Crapolina. That seems like a bug, or at least an engineering mistake. It may not display this or other websites correctly. sudo bless --folder /[mountpath]/System/Library/CoreServices --bootefi --create-snapshot. 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. 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. Howard. 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. This can take several attempts. Howard. Howard. Assuming you have entered the Recovery mode already, by holding down the Power button when powering-up/rebooting. When Authenticated Root is enabled the macOS is booted from a signed volume that is cryptographically protected to prevent tampering with the system volume. Would it really be an issue to stay without cryptographic verification though? Its free, and the encryption-decryption handled automatically by the T2. Same issue as you on my MacOS Monterey 12.0.1, Mackbook Pro 2021 with M1 Pro. Please how do I fix this? Its not the encrypted APFS that you would use on external storage, but implemented in the T2 as disk controller. This is because the SIP configuration is stored directly in the Security Policy (aka the LocalPolicy). System Integrity Protection (SIP) and the Security Policy (LocalPolicy) are not the same thing. and how about updates ? Click again to start watching. I wish you success with it. Thank you hopefully that will solve the problems. 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? 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. Disabling rootless is aimed exclusively at advanced Mac users. 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 Immutable system files now reside on the System volume, which not only has complete protection by SIP, but is normally mounted read-only. Authenticated Root _MUST_ be enabled. Encryption should be in a Volume Group. 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. Disable System Integrity Protection with command: csrutil disable csrutil authenticated-root disable. 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). 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. Apples Develop article. . However it did confuse me, too, that csrutil disable doesn't set what an end user would need. 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. So for a tiny (if that) loss of privacy, you get a strong security protection. If anyone finds a way to enable FileVault while having SSV disables please let me know. Thankfully, with recent Macs I dont have to engaged in all that fragile tinkering. This saves having to keep scanning all the individual files in order to detect any change. captured in an electronic forum and Apple can therefore provide no guarantee as to the efficacy of Thanks for the reply! SuccessCommand not found2015 Late 2013 You can then restart using the new snapshot as your System volume, and without SSV authentication. 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. restart in Recovery Mode strickland funeral home pooler, ga; richest instagram influencers non celebrity; mtg bees deck; business for sale st maarten 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.. Im not saying only Apple does it. Youre now watching this thread and will receive emails when theres activity. 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? The OS environment does not allow changing security configuration options. To make that bootable again, you have to bless a new snapshot of the volume using a command such as Best regards. My OS version is macos Monterey12.0.1, and my device is MacBook Pro 14'' 2021. SIP is about much more than SIP, of course, and when you disable it, you cripple your platform security. If you put your trust in Microsoft, or in yourself in the case of Linux, you can work well (so Im told) with either. If you choose to modify the system, you cant reseal that, but you can run Big Sur perfectly well without a seal. Apple hasnt, as far as Im aware, made any announcement about changes to Time Machine.

Restart or shut down your Mac and while starting, press Command + R key combination. Apple acknowledged it was a bug, but who knows in Big Sur yet (I havent had a chance to test yet). 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. There are a lot of things (privacy related) that requires you to modify the system partition Therefore, I usually use my custom display profile to enable HiDPI support at 2560x1080, which requires access to. 1- break the seal (disable csrutil and authenticated root) 2- delete existing snapshot (s) and tag an empty one to be able to boot 3- inject the kext with opencore (not needed if you are able to load the kext from /S/L/E.. Level 1 8 points `csrutil disable` command FAILED. https://arstechnica.com/gadgets/2020/11/apple-lets-some-big-sur-network-traffic-bypass-firewalls/. Further hashing is used in the file system metadata itself, from the deepest directories up to the root node, where its called the seal. JavaScript is disabled. This is because, unlike the T2 chip, the M1 manages security policy per bootable OS. I like things to run fast, really fast, so using VMs is not an option (I use them for testing). For the great majority of users, all this should be transparent. Yeah, my bad, thats probably what I meant. VM Configuration. []. I will look at this shortly, but I have a feeling that the hashes are inaccessible except by macOS. I really dislike Apple for adding apps which I cant remove and some of them I cant even use (like FaceTime / Siri on a Mac mini) Oh well Ill see what happens when the European Commission has made a choice by forcing Apple to stop pre-installing apps on their IOS devices.maybe theyll add macOS as well. As explained above, in order to do this you have to break the seal on the System volume. However, you can always install the new version of Big Sur and leave it sealed. Search. If you still cannot disable System Integrity Protection after completing the above, please let me know. The file resides in /[mountpath]/Library/Displays/Contents/Resources/Overrides therefore for Catalina I used Recovery Mode to edit those files. By reviewing the authentication log, you may see both authorized and unauthorized login attempts. 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). Still stuck with that godawful big sur image and no chance to brand for our school? Maybe when my M1 Macs arrive. That is the big problem. REBOOTto the bootable USBdrive of macOS Big Sur, once more. Am I right in thinking that once you disable authenticated-root, you cannot enable it if youve made changes to the system volume? In macOS Mojave 10.14, macOS boots from a single APFS volume, in which sensitive system folders and files are mixed with those which users can write to. Simply create a folder structure /Library/Displays/Contents/Resources/Overrides and copy there your folder with the patched EDID override file you have created for your screen (DisplayVendorID-XXXX/DisplayProductID-XXXX). 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). So, if I wanted to change system icons, how would I go about doing that on Big Sur? The seal is verified against the value provided by Apple at every boot. Normally, you should be able to install a recent kext in the Finder. Whos stopping you from doing that? Well, privacy goes hand in hand with security, but should always be above, like any form of freedom. The root volume is now a cryptographically sealed apfs snapshot. The sealed System Volume isnt crypto crap I really dont understand what you mean by that. Loading of kexts in Big Sur does not require a trip into recovery. Mount root partition as writable https://forums.macrumors.com/threads/macos-11-big-sur-on-unsupported-macs-thread.2242172/page-264, There is a big-sur-micropatcher that makes unlocking and patching easy here: Mojave boot volume layout Because of this, the symlink in the usr folder must reside on the Data volume, and thus be located at: /System/Volumes/Data/usr.

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 In the end, you either trust Apple or you dont. As thats on the writable Data volume, there are no implications for the protection of the SSV. Couldnt create snapshot on volume /Volumes/Macintosh HD: Operation not permitted, -bash-3.2# bless folder /Volumes/Macintosh\ HD/System/Library/CoreServices/ bootefi create-snapshot As I dont spend all day opening apps, that overhead is vanishingly small for me, and the benefits very much greater. (ex: /System/Library/Frameworks/NetworkExtension.framework/Versions/A/Resources/Info.plist). Howard. Again, no urgency, given all the other material youre probably inundated with. It would seem silly to me to make all of SIP hinge on SSV. Im guessing theres no TM2 on APFS, at least this year. Whatever you use to do that needs to preserve all the hashes and seal, or the volume wont be bootable. Big Sur really isnt intended to be used unsealed, which in any case breaks one of its major improvements in security. csrutil disable csrutil authenticated-root disable reboot Boot back into macOS and issue the following: Code: mount Note the "X" and "Y" values in "diskXsYsZ" on the first line, which. Ensure that the system was booted into Recovery OS via the standard user action. This will be stored in nvram.

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. This ensures those hashes cover the entire volume, its data and directory structure. Please post your bug number, just for the record. Im sorry, although Ive upgraded two T2 Macs, both were on the internal SSD which is encrypted anyway, and not APFS encrypted. Restart your Mac and go to your normal macOS.
