This crypto volume crap is definitely a mouth gag for the power USER, not hackers, or malware. 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) Howard. Very few people have experience of doing this with Big Sur. 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. Ive written a more detailed account for publication here on Monday morning. Come to think of it Howard, half the fun of using your utilities is that well, theyre fun. if your root is /dev/disk1s2s3, you'll mount /dev/disk1s2 Create a new directory, for example ~/ mount Run sudo mount -o nobrowse -t apfs DISK_PATH MOUNT_PATH, using the values from above im able to remount read/write the system disk and modify the filesystem from there , rushing to help is quite positive. 1. disable authenticated root These options are also available: Permissive Security: All of the options permitted by Reduced Security are also permitted here. For the great majority of users, all this should be transparent. Thank you for the informative post. 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. To make the volume bootable ( here the technical details) a "sanitation" is required with a command such as: Howard. Incidentally, I am in total sympathy with the person who wants to change the icons of native apps. [] those beta issues, changes in Big Surs security scheme for the System volume may cause headaches for some usersif nothing else, reverting to Catalina will require []. Im sorry, although Ive upgraded two T2 Macs, both were on the internal SSD which is encrypted anyway, and not APFS encrypted. Full disk encryption is about both security and privacy of your boot disk. you're booting from your internal drive recovery mode, so: A) el capitan is on your internal drive type /usr/bin/csrutil disable B) el capitan is on your external . I will look at this shortly, but I have a feeling that the hashes are inaccessible except by macOS. twitter wsdot. 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. 1-800-MY-APPLE, or, https://support.apple.com/guide/mac-help/macos-recovery-a-mac-apple-silicon-mchl82829c17/mac, Sales and 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. does uga give cheer scholarships. 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. Thank you yes, weve been discussing this with another posting. captured in an electronic forum and Apple can therefore provide no guarantee as to the efficacy of Im guessing theres no TM2 on APFS, at least this year. 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. and thanks to all the commenters! Most probable reason is the system integrity protection (SIP) - csrutil is the command line utility. It may not display this or other websites correctly. Thank you I have corrected that now. 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? 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. But no apple did horrible job and didnt make this tool available for the end user. FYI, I found most enlightening. (ex: /System/Library/Frameworks/NetworkExtension.framework/Versions/A/Resources/Info.plist). Nov 24, 2021 6:03 PM in response to agou-ops. 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. That is the big problem. Even with a non-T2 chip Mac, this was not the correct/sufficient way to encrypt the boot disk. and disable authenticated-root: csrutil authenticated-root disable. Howard. Ive been running a Vega FE as eGPU with my macbook pro. The SSV is very different in structure, because its like a Merkle tree. There were apps (some that I unfortunately used), from the App Store, that leaked sensitive information. 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. Click again to stop watching or visit your profile/homepage to manage your watched threads. Given the, I have a 34 inch ultrawide monitor with a 3440x1440 resolution, just below the threshold for native HiDPI support. 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). mount -uw /Volumes/Macintosh\ HD. And afterwards, you can always make the partition read-only again, right? 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. As thats on the writable Data volume, there are no implications for the protection of the SSV. Howard. The error is: cstutil: The OS environment does not allow changing security configuration options. Thank you so much for that: I misread that article! Because of this, the symlink in the usr folder must reside on the Data volume, and thus be located at: /System/Volumes/Data/usr. But I fathom that the M1 MacBook Pro arriving later this week might give it all a run for the money. So having removed the seal, could you not re-encrypt the disks? as you hear the Apple Chime press COMMAND+R. Howard. Howard. Sadly, everyone does it one way or another. Thank you. Id be interested to know in what respect you consider those or other parts of Big Sur break privacy. The bputil man page (in macOS, open Terminal, and search for bputil under the Help menu). When data is read from the SSV, its current hash is compared with the stored hash to verify that the file hasnt been tampered with or damaged. I dont. 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. You dont have a choice, and you should have it should be enforced/imposed. I think Id stick with the default icons!

Howard. Howard. To remove the symlink, try disabling SIP temporarily (which is most likely protecting the symlink on the Data volume). This workflow is very logical. Thanks. How you can do it ? Thanks in advance. For a better experience, please enable JavaScript in your browser before proceeding. The Mac will then reboot itself automatically. Im sorry, I dont know. 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? Just great. This will be stored in nvram. Personal Computers move to the horrible iPhone model gradually where I cannot modify my private owned hardware on my own. If you cant trust it to do that, then Linux (or similar) is the only rational choice. Im not saying only Apple does it. 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. 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. I input the root password, well, I should be able to do whatever I want, wipe the disk or whatever. All good cloning software should cope with this just fine. Thanks for the reply! But I'm already in Recovery OS. And we get to the you dont like, dont buy this is also wrong. I also read somewhere that you could only disable SSV with FireVault off, but that definitely needs to stay on. Update: my suspicions were correct, mission success! ). Loading of kexts in Big Sur does not require a trip into recovery. 3. boot into OS . Press Esc to cancel. Im sure there are good reasons why it cant be as simple, but its hardly efficient. Hey Im trying to create the new snapshot because my Mac Pro (Mid 2014) has the issue where it randomly shutdown because of an issue with the AppleThunderboltNHI.kext found in /Volumes/Macintosh\ HD/System/Library/Extensions. Its authenticated. An how many in 100 users go in recovery, use terminal commands just to edit some config files ? Im sure that well see bug fixes, but whether it will support backups on APFS volumes I rather doubt. Certainly not Apple. 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. And when your system is compromised, what value was there in trying to stop Apple getting private data in the first place? 1. - mkidr -p /Users//mnt (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. 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. If you dont trust Apple, then you really shouldnt be running macOS. Further hashing is used in the file system metadata itself, from the deepest directories up to the root node, where its called the seal. It is that simple. lagos lockdown news today; csrutil authenticated root disable invalid command Type at least three characters to start auto complete. 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. (I imagine you have your hands full this week and next investigating all the big changes, so if you cant delve into this now thats certainly understandable.) Yes. 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). By reviewing the authentication log, you may see both authorized and unauthorized login attempts. I wish you success with it. BTW, I thought that I would not be able to get it past Catalalina, but Big Sur is running nicely. 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). 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. Now I can mount the root partition in read and write mode (from the recovery): []. You need to disable it to view the directory. `csrutil disable` command FAILED. This command disables volume encryption, "mounts" the system volume and makes the change. Apple may provide or recommend responses as a possible solution based on the information You like where iOS is? 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 . Hello all, I was recently trying to disable the SIP on my Mac, and therefore went to recovery mode. Increased protection for the system is an essential step in securing macOS. 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) A forum where Apple customers help each other with their products. Any suggestion? 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) A simple command line tool appropriately called 'dsenableroot' will quickly enable the root user account in Mac OS X. Assuming Apple doesnt remove that functionality before release then that implies more efficient (and hopefully more reliable) TM backups. 6. undo everything and enable authenticated root again. Yes Skip to content HomeHomeHome, current page. This can take several attempts. 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). 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. Your mileage may differ. It shouldnt make any difference. Would you want most of that removed simply because you dont use it? Thank you. It had not occurred to me that T2 encrypts the internal SSD by default. 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). macOS 12.0. Encryption should be in a Volume Group. Have you reported it to Apple? and seal it again. For without ensuring rock-solid security as the basis for protecting privacy, it becomes all too easy to bypass everything. 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. So whose seal could that modified version of the system be compared against? Another update: just use this fork which uses /Libary instead. 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. However, it very seldom does at WWDC, as thats not so much a developer thing. I figured as much that Apple would end that possibility eventually and now they have. If you choose to modify the system, you cant reseal that, but you can run Big Sur perfectly well without a seal. SIP is locked as fully enabled. If that cant be done, then you may be better off remaining in Catalina for the time being. Best regards. 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.

This thread has a lot of useful info for supporting the older Mac no longer supported by Big Sur. Every time you need to re-disable SSV, you need to temporarily turn off FileVault each time. Maybe I can convince everyone to switch to Linux (more likely- Windows, since people wont give up their Adobe and MicroSoft products). One unexpected problem with unsealing at present is that FileVault has to be disabled, and cant be enabled afterwards. Theres a world of difference between /Library and /System/Library! I like things to run fast, really fast, so using VMs is not an option (I use them for testing).

Keep default option and press next. Am I out of luck in the future? All that needed to be done was to install Catalina to an unencrypted disk (the default) and, after installation, enable FileVault in System Preferences. 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. Big Sur really isnt intended to be used unsealed, which in any case breaks one of its major improvements in security. Well, I though the entire internet knows by now, but you can read about it here: 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? 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 Howard. 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 addition, you can boot a custom kernel (the Asahi Linux team is using this to allow booting Linux in the future). Restart your Mac and go to your normal macOS. Boot into (Big Sur) Recovery OS using the . The thing is, encrypting or making the /System read-only does not prevent malware, rogue apps or privacy invading programs. It's much easier to boot to 1TR from a shutdown state. Howard. In any case, what about the login screen for all users (i.e. Thank you. sudo bless --folder /[mountpath]/System/Library/CoreServices --bootefi --create-snapshot to create the new snapshot and bless it How can I solve this problem? Does running unsealed prevent you from having FileVault enabled? 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. 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) Disabling rootless is aimed exclusively at advanced Mac users.

Apple keeps telling us how important privacy is for them, and then they whitelist their apps so they have unrestricted access to internet. Catalina boot volume layout The first option will be automatically selected. Howard. On Macs with Apple silicon SoCs, the SIP configuration is stored inside the LocalPolicy file - SIP is a subset of the security policy. (refer to https://support.apple.com/guide/mac-help/macos-recovery-a-mac-apple-silicon-mchl82829c17/mac). Its free, and the encryption-decryption handled automatically by the T2. the notorious "/Users/Shared/Previously Relocated Items" garbage, forgot to purge before upgrading to Catalina), do "sudo mount -uw /System/Volumes/Data/" first (run in the Terminal after normal booting). You missed letter d in csrutil authenticate-root disable. And putting it out of reach of anyone able to obtain root is a major improvement. SSV seems to be an evolution of that, similar in concept (if not of execution), sort of Tripwire on steroids. Ever. Search. No need to disable SIP. NOTE: Authenticated Root is enabled by default on macOS systems. Id like to modify the volume, get rid of some processes who bypasses the firewalls (like Little Snitch read their blog!) Refunds. If you really feel the need or compulsion to modify files on the System volume, then perhaps youd be better sticking with Catalina?

Thank you yes, thats absolutely correct. 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.. Howard. I suspect that quite a few are already doing that, and I know of no reports of problems. There are a lot of things (privacy related) that requires you to modify the system partition 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: Well, privacy goes hand in hand with security, but should always be above, like any form of freedom. You can run csrutil status in terminal to verify it worked. Those familiar with my file integrity tools will recognise that this is essentially the same technique employed by them. But he knows the vagaries of Apple. For some, running unsealed will be necessary, but the great majority of users shouldnt even consider it as an option. Howard, I am trying to do the same thing (have SSV disables but have FileVault enabled). 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. Howard. Select "Custom (advanced)" and press "Next" to go on next page.

The only time youre likely to come up against the SSV is when using bootable macOS volumes by cloning or from a macOS installer. kent street apartments wilmington nc. [] Big Sur further secures the System volume by applying a cryptographic hash to every file on it, as Howard Oakley explains. Period. In T2 Macs, their internal SSD is encrypted. Unfortunately I cant get past step 1; it tells me that authenticated root is an invalid command in recovery. I understand the need for SIP, but its hard to swallow this if it has performance impact even on M1. It effectively bumps you back to Catalina security levels. 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.. In Catalina, the root volume could be mounted as read/write by disabling SIP and entering the following command: Try changing your Secure Boot option to "Medium Security" or "No Security" if you are on a computer with a T2 chip.
