Id like to modify the volume, get rid of some processes who bypasses the firewalls (like Little Snitch read their blog!) This can take several attempts. []. 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 up to the user to strike the balance. 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. Howard. Apples Develop article. During the prerequisites, you created a new user and added that user . 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. But I fathom that the M1 MacBook Pro arriving later this week might give it all a run for the money. Further hashing is used in the file system metadata itself, from the deepest directories up to the root node, where its called the seal. Am I out of luck in the future? any proposed solutions on the community forums. Youre now watching this thread and will receive emails when theres activity.

A walled garden where a big boss decides the rules. If you choose to modify the system, you cant reseal that, but you can run Big Sur perfectly well without a seal. 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. Thank you hopefully that will solve the problems. 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).

Im sure there are good reasons why it cant be as simple, but its hardly efficient. 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. It shouldnt make any difference. (ex: /System/Library/Frameworks/NetworkExtension.framework/Versions/A/Resources/Info.plist). Available in Startup Security Utility. Howard. How can a malware write there ? . Follow these step by step instructions: reboot. If I didnt trust Apple, then I wouldnt do business with them, nor develop software for macOS. Enabling FileVault doesnt actually change the encryption, but restricts access to those keys. https://github.com/barrykn/big-sur-micropatcher. Would you like to proceed to legacy Twitter? 4. 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. Why is kernelmanagerd using between 15 and 55% of my CPU on BS? Its free, and the encryption-decryption handled automatically by the T2. Great to hear! For without ensuring rock-solid security as the basis for protecting privacy, it becomes all too easy to bypass everything. Thanks for the reply! Sure. For a better experience, please enable JavaScript in your browser before proceeding. Heres hoping I dont have to deal with that mess. Apparently you can now use an APFS-formatted drive with Time Machine in Big Sur: https://appleinsider.com/articles/20/06/27/apfs-changes-affect-time-machine-in-macos-big-sur-encrypted-drives-in-ios-14, Under Big Sur, users will be able to back up directly to an APFS-formatted drive, eliminating the need to reformat any disks.. call Thank you. One unexpected problem with unsealing at present is that FileVault has to be disabled, and cant be enabled afterwards. enrollment profile that requires FileVault being enabled at all times, this can lead to even more of a headache. FYI, I found most enlightening. At its native resolution, the text is very small and difficult to read. Always.

It looks like the hashes are going to be inaccessible. You missed letter d in csrutil authenticate-root disable. But I wouldnt have thought thered be any fundamental barrier to enabling this on a per-folder basis, if Apple wanted to. That isnt the case on Macs without a T2 chip, though, where you have to opt to turn FileVault on or off. Thus no user can re-seal a system, only an Apple installer/updater, or its asr tool working from a sealed clone of the system. Search articles by subject, keyword or author. Why do you need to modify the root volume? I was trying to disable SIP on my M1 MacBook Pro when I found doing so prevents the Mac from running iOS apps an alert will appear upon launching that the app cant be opened because Security Policy is set to Permissive Security and Ill need to change the Security Policy to Full Security or Reduced Security..

Show results from. Mount root partition as writable I think this needs more testing, ideally on an internal disk. It is already a read-only volume (in Catalina), only accessible from recovery! and they illuminate the many otherwise obscure and hidden corners of macOS. 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. At some point you just gotta learn to stop tinkering and let the system be. only. You dont have a choice, and you should have it should be enforced/imposed. 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. Run "csrutil clear" to clear the configuration, then "reboot". Incidentally, I just checked prices on an external 1 TB SSD and they can be had for under $150 US. As Apples security engineers know exactly how that is achieved, they obviously understand how it is exploitable. Your mileage may differ. Then you can follow the same steps as earlier stated - open terminal and write csrutil disable/enable. Encryptor5000, csrutil not working on recovery mode command not found iMac 2011 running high Sierra, Hi. Click the Apple symbol in the Menu bar. Thank you. It sounds like Apple may be going even further with Monterey. Then you can boot into recovery and disable SIP: csrutil disable. 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? That said, would you describe installing macOS the way I did with Catalina as redundant if my Mac has a T2 chip? Here are the steps. You can then restart using the new snapshot as your System volume, and without SSV authentication. It would seem silly to me to make all of SIP hinge on SSV. It is that simple. An how many in 100 users go in recovery, use terminal commands just to edit some config files ? You can have complete confidence in Big Sur that nothing has nobbled whats on your System volume. yes i did. 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 Looks like no ones replied in a while. 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). c. Keep default option and press next. Thank you I have corrected that now. So use buggy Catalina or BigBrother privacy broken Big Sur great options.. By the way, I saw about macs with T2 always encrypted stuff, just never tested like if there is no password set (via FileVault enabled by user), then it works like a bitlocker Windows disk on a laptop with TPM ? Hoakley, Thanks for this! d. Select "I will install the operating system later". A forum where Apple customers help each other with their products. I use it for my (now part time) work as CTO. Select "Custom (advanced)" and press "Next" to go on next page. Howard. and seal it again. Just yesterday I had to modify var/db/com.apple.xpc.launchd/disabled.501.plist because if you unload something, it gets written to that file and stays there forever, even if the app/agent/daemon is no longer present that is a trace you may not want someone to find. In the end, you either trust Apple or you dont. There is no more a kid in the basement making viruses to wipe your precious pictures. 4. mount the read-only system volume Step 1 Logging In and Checking auth.log. Howard. The only difference is that with a non-T2 Mac the encryption will be done behind the scenes after enabling FileVault. Thanks for your reply. 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. I wanted to make a thread just to raise general awareness about the dangers and caveats of modifying system files in Big Sur, since I feel this doesn't really get highlighted enough. These options are also available: Permissive Security: All of the options permitted by Reduced Security are also permitted here. Theres no way to re-seal an unsealed System. Run csrutil authenticated-root disableto disable the authenticated root from the System Integrity Protection (SIP). To start the conversation again, simply Please support me on Patreon: https://www.patreon.com/roelvandepaarWith thanks & praise to God, and with . csrutil authenticated-root disable as well. In Catalina, making changes to the System volume isnt something to embark on without very good reason. Thank you. 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. 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. SIP is locked as fully enabled. Any suggestion? Without in-depth and robust security, efforts to achieve privacy are doomed. Howard. csrutil authenticated root disable invalid commandverde independent obituaries. Of course, when an update is released, this all falls apart.

Ive been running a Vega FE as eGPU with my macbook pro. In Release 0.6 and Big Sur beta x ( i dont remember) i can installed Big Sur but keyboard not working (A). Apple acknowledged it was a bug, but who knows in Big Sur yet (I havent had a chance to test yet). These are very early days with the SSV, and I think well learn the rules and wrinkles in the coming weeks. This is a long and non technical debate anyway . For now. 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. Update: my suspicions were correct, mission success! 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. Theres a world of difference between /Library and /System/Library! sudo bless --folder /[mountpath]/System/Library/CoreServices --bootefi --create-snapshot. Customizing or disabling SIP will automatically downgrade the security policy to Permissive Security. To remove the symlink, try disabling SIP temporarily (which is most likely protecting the symlink on the Data volume). Howard. Can you re-enable the other parts of SIP that do not revolve around the cryptographic hashes? With an upgraded BLE/WiFi watch unlock works. All good cloning software should cope with this just fine. Apple cant provide thousands of different seal values to cater for every possible combination of change system installations. Well, privacy goes hand in hand with security, but should always be above, like any form of freedom. Thankfully, with recent Macs I dont have to engaged in all that fragile tinkering. By the way, T2 is now officially broken without the possibility of an Apple patch Just reporting a finding from today that disabling SIP speeds-up launching of apps 2-3 times versus SIP enabled!!! I also expect that you will be able to install a delta update to an unsealed system, leaving it updated but unsealed. Ever. I have now corrected this and my previous article accordingly. 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? Refunds. Certainly not Apple. Encryption should be in a Volume Group. Now do the "csrutil disable" command in the Terminal. Howard. P.S. Maybe when my M1 Macs arrive. 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). I have a screen that needs an EDID override to function correctly. For example, when you open an app without a quarantine flag, several different parts of the security and privacy system perform checks on its signature. The thing is, encrypting or making the /System read-only does not prevent malware, rogue apps or privacy invading programs. Running multiple VMs is a cinch on this beast. Im not saying only Apple does 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. All postings and use of the content on this site are subject to the. NOTE: Authenticated Root is enabled by default on macOS systems. Apple hasnt, as far as Im aware, made any announcement about changes to Time Machine. The seal is verified against the value provided by Apple at every boot. You can run csrutil status in terminal to verify it worked. 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 . I do have to ditch authenticated root to enable the continuity flag for my MB, but thats it. Mojave boot volume layout Restart or shut down your Mac and while starting, press Command + R key combination. 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 can verify with "csrutil status" and with "csrutil authenticated-root status". Thank you. 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. Thank you. In any case, what about the login screen for all users (i.e. I dont think its novel by any means, but extremely ingenious, and I havent heard of its use in any other OS to protect the system files. and thanks to all the commenters! Still stuck with that godawful big sur image and no chance to brand for our school? 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) that was shown already at the link i provided. I understand the need for SIP, but its hard to swallow this if it has performance impact even on M1. # csrutil status # csrutil authenticated-root status RecoveryterminalSIP # csrutil authenticated-root disable # csrutil disable. Touchpad: Synaptics. csrutil authenticated-root disable to disable crypto verification You want to sell your software? 3. boot into OS And when your system is compromised, what value was there in trying to stop Apple getting private data in the first place? If you want to delete some files under the /Data volume (e.g. Howard, I am trying to do the same thing (have SSV disables but have FileVault enabled). But what you cant do is re-seal the SSV, which is the whole point of Big Surs improved security. 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 Story. I will look at this shortly, but I have a feeling that the hashes are inaccessible except by macOS. Loading of kexts in Big Sur does not require a trip into recovery. And we get to the you dont like, dont buy this is also wrong. Not necessarily a volume group: a VG encrypts as a group, but volumes not in a group can of course be encrypted individually. This will be stored in nvram. Thank you. restart in Recovery Mode Howard. It may not display this or other websites correctly. Hell, they wont even send me promotional email when I request it! 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? 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.. Sorted by: 2. Restart your Mac and go to your normal macOS. Trust me: you really dont want to do this in Big Sur. Apple disclaims any and all liability for the acts, omissions and conduct of any third parties in connection with or related to your use of the site. Got it working by using /Library instead of /System/Library. 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. 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. And afterwards, you can always make the partition read-only again, right? 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). Thank you. JavaScript is disabled. If you still cannot disable System Integrity Protection after completing the above, please let me know. Late reply rescanning this post: running with csrutil authenticated-root disable does not prevent you from enabling SIP later. csrutil authenticated-root disable 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. 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. It is well-known that you wont be able to use anything which relies on FairPlay DRM. I'd say: always have a bootable full backup ready . Yep. does uga give cheer scholarships. Im a bit of a noob with all this, but could you clarify, would I need to install the kext using terminal in recovery mode? Howard. In Catalina you could easily move the AppleThunderboltNHI.kext to a new folder and it worked fine, but with the Big Sur beta you cant do that. Have you reported it to Apple as a bug? Thanks, we have talked to JAMF and Apple. I booted using the volume containing the snapshot (Big Sur Test for me) and tried enabling FIleVault which failed. Thanks in advance. 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. macOS 12.0. 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? e. So, if I wanted to change system icons, how would I go about doing that on Big Sur? That seems like a bug, or at least an engineering mistake. My MacBook Air is also freezing every day or 2. hf zq tb. It sleeps and does everything I need. My machine is a 2019 MacBook Pro 15. 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. This site contains user submitted content, comments and opinions and is for informational purposes 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..
