Customizing or disabling SIP will automatically downgrade the security policy to Permissive Security. (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.) I solved this problem by completely shutting down, then powering on, and finally restarting the computer to Recovery OS. A good example is OCSP revocation checking, which many people got very upset about. In Release 0.6 and Big Sur beta x ( i dont remember) i can installed Big Sur but keyboard not working (A). 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 cant trust it to do that, then Linux (or similar) is the only rational choice. Mojave boot volume layout provided; every potential issue may involve several factors not detailed in the conversations 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. 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. 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. `csrutil disable` command FAILED. csrutil authenticated root disable invalid commandhow to get cozi tv. "Invalid Disk: Failed to gather policy information for the selected disk" Encrypted APFS volumes are intended for general storage purposes, not for boot volumes. 1. disable authenticated root And we get to the you dont like, dont buy this is also wrong. Howard. Maybe I can convince everyone to switch to Linux (more likely- Windows, since people wont give up their Adobe and MicroSoft products). You may also boot to recovery and use Terminal to type the following commands: csrutil disable csrutil authenticated-root disable -> new in Big Sur. Yes, completely. All postings and use of the content on this site are subject to the. To make the volume bootable ( here the technical details) a "sanitation" is required with a command such as: We tinkerers get to tinker with them (without doing harm we hope always helps to read the READ MEs!) 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? Howard. csrutil authenticated-root disable thing to do, which requires first to disable FileVault, else that second disabling command simply fails. It would seem silly to me to make all of SIP hinge on SSV. % dsenableroot username = Paul user password: root password: verify root password: Whos stopping you from doing that? 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. Sadly, everyone does it one way or another. Howard. This to me is a violation. Also, you might want to read these documents if you're interested. 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). not give them a chastity belt. does uga give cheer scholarships.

( SSD/NVRAM ) All you need do on a T2 Mac is turn FileVault on for the boot disk. 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. Howard. SIP # csrutil status # csrutil authenticated-root status Disable For without ensuring rock-solid security as the basis for protecting privacy, it becomes all too easy to bypass everything. Do you guys know how this can still be done so I can remove those unwanted apps ? Anyone knows what the issue might be? Why is kernelmanagerd using between 15 and 55% of my CPU on BS? 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? Every security measure has its penalties. 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. 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. Hoakley, Thanks for this! This is because, unlike the T2 chip, the M1 manages security policy per bootable OS. [] 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.

These are very early days with the SSV, and I think well learn the rules and wrinkles in the coming weeks. Howard. agou-ops, User profile for user: Those familiar with my file integrity tools will recognise that this is essentially the same technique employed by them. 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. Assuming Apple doesnt remove that functionality before release then that implies more efficient (and hopefully more reliable) TM backups. 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. 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. That leaves your System volume without cryptographic verification, of course, and whether it will then successfully update in future must be an open question. Dont do anything about encryption at installation, just enable FileVault afterwards. [] Big Sur further secures the System volume by applying a cryptographic hash to every file on it, as Howard Oakley explains. By the way, T2 is now officially broken without the possibility of an Apple patch Does running unsealed prevent you from having FileVault enabled? The only choice you have is whether to add your own password to strengthen its encryption. Have you contacted the support desk for your eGPU? The OS environment does not allow changing security configuration options. In outline, you have to boot in Recovery Mode, use the command 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. Howard. -l Block OCSP, and youre vulnerable. Howard, I am trying to do the same thing (have SSV disables but have FileVault enabled). Ensure that the system was booted into Recovery OS via the standard user action. Today we have the ExclusionList in there that cant be modified, next something else. The first option will be automatically selected. 5. change icons Howard. []. The System volume within a boot Volume Group is now sealed using a tree of cryptographic hashes, as I have detailed here. Howard. # csrutil status # csrutil authenticated-root status RecoveryterminalSIP # csrutil authenticated-root disable # csrutil disable. Always. Am I out of luck in the future? Still stuck with that godawful big sur image and no chance to brand for our school? . Story. Im sure there are good reasons why it cant be as simple, but its hardly efficient.

Since FileVault2 is handled for the whole container using the T2 I suspect, it will still work. I seem to recall that back in the olden days of Unix, there was an IDS (Intrusion Detection System) called Tripwire which stored a checksum for every system file and watched over them like a hawk. Maybe when my M1 Macs arrive. Thank you. 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. Howard. Very few people have experience of doing this with Big Sur. So, if I wanted to change system icons, how would I go about doing that on Big Sur? Howard. Our Story; Our Chefs Every time you need to re-disable SSV, you need to temporarily turn off FileVault each time. SIP I understand is hugely important, and I would not dream of leaving it disabled, but SSV seems overkill for my use. What definitely does get much more complex is altering anything on the SSV, because you cant simply boot your Mac from a live System volume any more: that will fail these new checks. Mount root partition as writable Do so at your own risk, this is not specifically recommended. 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. i drink every night to fall asleep. csrutil authenticated root disable invalid commandverde independent obituaries. Im not sure what your argument with OCSP is, Im afraid. The last two major releases of macOS have brought rapid evolution in the protection of their system files. As Apples security engineers know exactly how that is achieved, they obviously understand how it is exploitable. The OS environment does not allow changing security configuration options. Am I right in thinking that once you disable authenticated-root, you cannot enable it if youve made changes to the system volume? Apple hasnt, as far as Im aware, made any announcement about changes to Time Machine.

Its very visible esp after the boot. 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. This saves having to keep scanning all the individual files in order to detect any change. Its not the encrypted APFS that you would use on external storage, but implemented in the T2 as disk controller. network users)? csrutil authenticated-root disable csrutil disable But what you cant do is re-seal the SSV, which is the whole point of Big Surs improved security. In addition, you can boot a custom kernel (the Asahi Linux team is using this to allow booting Linux in the future). Without in-depth and robust security, efforts to achieve privacy are doomed. Nov 24, 2021 4:27 PM in response to agou-ops. after all SSV is just a TOOL for me, to be sure about the volume integrity. FYI, I found most enlightening. 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. 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? Run the command "sudo. csrutil authenticated-root disable returns invalid command authenticated-root as it doesn't recognize the option. But if youre turning SIP off, perhaps you need to talk to JAMF soonest. It is that simple. Would it really be an issue to stay without cryptographic verification though? 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. I use it for my (now part time) work as CTO. 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 Increased protection for the system is an essential step in securing macOS. Update: my suspicions were correct, mission success! Short answer: you really dont want to do that in Big Sur. 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. A walled garden where a big boss decides the rules. 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 your case, that probably doesnt help you run highly privileged utilities, but theyre not really consistent with Mac security over the last few years. NOTE: Authenticated Root is enabled by default on macOS systems. I also read somewhere that you could only disable SSV with FireVault off, but that definitely needs to stay on. 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. Thank you, and congratulations. Id like to modify the volume, get rid of some processes who bypasses the firewalls (like Little Snitch read their blog!) For a better experience, please enable JavaScript in your browser before proceeding. 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. 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 ? Im sorry, although Ive upgraded two T2 Macs, both were on the internal SSD which is encrypted anyway, and not APFS encrypted. Thank you. 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. All that needed to be done was to install Catalina to an unencrypted disk (the default) and, after installation, enable FileVault in System Preferences. gpc program process steps .

Best regards. P.S. But he knows the vagaries of Apple. Intriguingly, I didnt actually changed the Permissive Security Policy myself at all it seems that executing `csrutil disable` has the side effect of reduce the policy level to Permissive, and tuning the policy level up to Reduced or Full also force re-enabling SIP. 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 I figured as much that Apple would end that possibility eventually and now they have. Howard. Hoping that option 2 is what we are looking at. But Apple puts that seal there to warrant that its intact in accordance with Apples criteria.

Authenticated Root _MUST_ be enabled. Search. My wifes Air is in today and I will have to take a couple of days to make sure it works. In Mojave and Catalina I used to be able to remove the preinstalled apps from Apple by disabling system protection in system recovery and then in Terminal mounting the volume but in Big Sur I found that this isnt working anymore since I ran into an error when trying to mount the volume in Terminal. (refer to https://support.apple.com/guide/mac-help/macos-recovery-a-mac-apple-silicon-mchl82829c17/mac). Apple keeps telling us how important privacy is for them, and then they whitelist their apps so they have unrestricted access to internet. Or could I do it after blessing the snapshot and restarting normally? Howard. Restart or shut down your Mac and while starting, press Command + R key combination. Theres a world of difference between /Library and /System/Library! 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. ). Again, no urgency, given all the other material youre probably inundated with. See: About macOS recovery function: Restart the computer, press and hold command + R to enter the recovery mode when the screen is black (you can hold down command + R until the apple logo screen appears) to enter the recovery mode, and then click the menu bar, " Utilities >> Terminal".
