This is a long and non technical debate anyway . @hoakley With each release cycle I think that the days of my trusty Mac Pro 5,1 are done. The seal is verified each time your Mac starts up, by the boot loader before the kernel is loaded, and during installation and update of macOS system files. Now I can mount the root partition in read and write mode (from the recovery): How you can do it ? 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. Id be interested to hear some old Unix hands commenting on the similarities or differences. JavaScript is disabled. Yes, I remember Tripwire, and think that at one time I used it. VM Configuration. If you can do anything with the system, then so can an attacker. On Macs with Apple silicon SoCs, the SIP configuration is stored inside the LocalPolicy file - SIP is a subset of the security policy. Every file on Big Surs System volume now has a SHA-256 cryptographic hash which is stored in the file system metadata.. 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.. Short answer: you really dont want to do that in Big Sur. twitter wsdot. Show results from. Howard. 6. undo everything and enable authenticated root again. Howard. This thread has a lot of useful info for supporting the older Mac no longer supported by Big Sur. 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 (Also, Ive scoured all the WWDC reports I could find and havent seen any mention of Time Machine in regards to Big Sur. kent street apartments wilmington nc. (refer to https://support.apple.com/guide/mac-help/macos-recovery-a-mac-apple-silicon-mchl82829c17/mac). only. You can then restart using the new snapshot as your System volume, and without SSV authentication. 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. As explained above, in order to do this you have to break the seal on the System volume. 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? In Catalina, making changes to the System volume isnt something to embark on without very good reason. In T2 Macs, their internal SSD is encrypted. Sorted by: 2. Automaty Ggbet Kasyno Przypado Do Stylu Wielu Hazardzistom, Ktrzy Lubi Wysokiego Standardu Uciechy Z Nieprzewidywaln Fabu I Ciekawymi Bohaterami 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. You can verify with "csrutil status" and with "csrutil authenticated-root status". It is technically possible to get into what Apple calls "1 True Recovery (1TR)" via a reboot, but you have to hold down the power button (Touch ID) as soon as the display backlight turns off. You need to disable it to view the directory. not give them a chastity belt. 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. You may also boot to recovery and use Terminal to type the following commands: csrutil disable csrutil authenticated-root disable -> new in Big Sur. It had not occurred to me that T2 encrypts the internal SSD by default. Thank you yes, weve been discussing this with another posting. If that cant be done, then you may be better off remaining in Catalina for the time being. Thank you hopefully that will solve the problems. P.S. Hello all, I was recently trying to disable the SIP on my Mac, and therefore went to recovery mode. 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. Thank you so much for that: I misread that article! 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. Thank you. A simple command line tool appropriately called 'dsenableroot' will quickly enable the root user account in Mac OS X. You may be fortunate to live in Y country that has X laws at the moment not all are in the same boat. 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) That said, would you describe installing macOS the way I did with Catalina as redundant if my Mac has a T2 chip? It looks like the hashes are going to be inaccessible. Also, type "Y" and press enter if Terminal prompts for any acknowledgements. Big Sur really isnt intended to be used unsealed, which in any case breaks one of its major improvements in security. But I wouldnt have thought thered be any fundamental barrier to enabling this on a per-folder basis, if Apple wanted to. Howard. Id like to modify the volume, get rid of some processes who bypasses the firewalls (like Little Snitch read their blog!) Does the equivalent path in/Librarywork for this? SIP is locked as fully enabled. 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. I must admit I dont see the logic: Apple also provides multi-language support. For a better experience, please enable JavaScript in your browser before proceeding. 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. omissions and conduct of any third parties in connection with or related to your use of the site. Howard. 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. Anyway, people need to learn, tot to become dumber thinking someone else has their back and they can stay dumb. ), that is no longer built into the prelinked kernel which is used to boot your system, instead being built into /Library/KernelCollections/AuxiliaryKernelExtensions.kc. Sounds like youd also be stuck on the same version of Big Sur if the delta updates arent able to verify the cryptographic information. Sadly, everyone does it one way or another. csrutil authenticated-root disable as well. Thats the command given with early betas it may have changed now. Best regards. Im sure that well see bug fixes, but whether it will support backups on APFS volumes I rather doubt. Its authenticated.

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. Further details on kernel extensions are here. Apple has been tightening security within macOS for years now. Is that with 11.0.1 release? That seems like a bug, or at least an engineering mistake. Mount root partition as writable Howard. You can checkout the man page for kmutil or kernelmanagerd to learn more . 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. Encrypted APFS volumes are intended for general storage purposes, not for boot volumes. Hoakley, Thanks for this! Im guessing theres no TM2 on APFS, at least this year. My machine is a 2019 MacBook Pro 15. OCSP? Howard. It is that simple. 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). Ensure that the system was booted into Recovery OS via the standard user action. [] Big Surs Signed System Volume: added security protection eclecticlight.co/2020/06/25/big-surs-signed-system-volume-added-security-protection/ []. And afterwards, you can always make the partition read-only again, right? Step 1 Logging In and Checking auth.log. 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) 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. 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 . If not, you should definitely file abugabout that. Anyone knows what the issue might be? Would it really be an issue to stay without cryptographic verification though? I am currently using a MacBook Pro 13-inch, Early 2011, and my OS version is 10.12.6. 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. Our Story; Our Chefs westerly kitchen discount code csrutil authenticated root disable invalid command Howard. But Apple puts that seal there to warrant that its intact in accordance with Apples criteria. 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). 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? Catalina 10.15 changes that by splitting the boot volume into two: the System and Data volumes, making up an APFS Volume Group. Very few people have experience of doing this with Big Sur. Update: my suspicions were correct, mission success! I have a screen that needs an EDID override to function correctly. The System volume within a boot Volume Group is now sealed using a tree of cryptographic hashes, as I have detailed here. Thank you. Theres no encryption stage its already encrypted. Your mileage may differ. To start the conversation again, simply Thank you. Dont do anything about encryption at installation, just enable FileVault afterwards. Ive been running a Vega FE as eGPU with my macbook pro. Thanks. Thank you. 2. bless All that needed to be done was to install Catalina to an unencrypted disk (the default) and, after installation, enable FileVault in System Preferences.

Each to their own csrutil disable csrutil authenticated-root disable # Big Sur+ Reboot, and SIP will have been adjusted accordingly. 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. Unfortunately I cant get past step 1; it tells me that authenticated root is an invalid command in recovery. Howard. And you let me know more about MacOS and SIP. Apple owns the kernel and all its kexts. 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. csrutil disable. you will be in the Recovery mode. Just reporting a finding from today that disabling SIP speeds-up launching of apps 2-3 times versus SIP enabled!!! 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. Thank you. Those familiar with my file integrity tools will recognise that this is essentially the same technique employed by them. i made a post on apple.stackexchange.com here: Therefore, I usually use my custom display profile to enable HiDPI support at 2560x1080, which requires access to /System/Library/Displays/Contents/Resources/Overrides/.

Im sorry, I dont know. Howard. But he knows the vagaries of Apple. 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? Then you can boot into recovery and disable SIP: csrutil disable. You get to choose which apps you use; you dont get to choose what malware can attack, and putting privacy above security seems eccentric to say the least. The OS environment does not allow changing security configuration options. % dsenableroot username = Paul user password: root password: verify root password: Type csrutil disable. My OS version is macos Monterey12.0.1, and my device is MacBook Pro 14'' 2021. How can I solve this problem? This saves having to keep scanning all the individual files in order to detect any change.

Every time you need to re-disable SSV, you need to temporarily turn off FileVault each time. I dont know about Windows, but the base setting for T2 Macs is that most of the contents of the internal storage is permanently encrypted using keys in the Secure Enclave of the T2. She has no patience for tech or fiddling. 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. mount the System volume for writing Boot into (Big Sur) Recovery OS using the . any proposed solutions on the community forums. Thank you I have corrected that now. 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. 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. Or could I do it after blessing the snapshot and restarting normally? Howard. Hopefully someone else will be able to answer that. Then i recreater Big Sur public beta with Debug 0.6.1 builded from OCBuilder but always reboot after choose install Big Sur, i found ib OC Wiki said about 2 case: Black screen after picker and Booting OpenCore reboots .

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. Howard. Further hashing is used in the file system metadata itself, from the deepest directories up to the root node, where its called the seal. Run csrutil authenticated-root disableto disable the authenticated root from the System Integrity Protection (SIP). It shouldnt make any difference. But why the user is not able to re-seal the modified volume again?

Yes, unsealing the SSV is a one-way street. I also expect that you will be able to install a delta update to an unsealed system, leaving it updated but unsealed. Incidentally, I am in total sympathy with the person who wants to change the icons of native apps. This in turn means that: If you modified system files on a portable installation of macOS (ie: on an external drive) via this method, any host computer you plug it into will fail to boot the drive if SSV is enabled on the host. Howard. molar enthalpy of combustion of methanol. Apple may provide or recommend responses as a possible solution based on the information 3. 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.

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). I'd say: always have a bootable full backup ready . Yep. Why choose to buy computers and operating systems from a vendor you dont feel you can trust? and seal it again. SIP I understand is hugely important, and I would not dream of leaving it disabled, but SSV seems overkill for my use. Howard. As I dont spend all day opening apps, that overhead is vanishingly small for me, and the benefits very much greater. It is already a read-only volume (in Catalina), only accessible from recovery!

Even with a non-T2 chip Mac, this was not the correct/sufficient way to encrypt the boot disk. 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.

Also, any details on how/where the hashes are stored? 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 Ever. Immutable system files now reside on the System volume, which not only has complete protection by SIP, but is normally mounted read-only.
