Every time you need to re-disable SSV, you need to temporarily turn off FileVault each time. Furthermore, users are reporting that before you can do that, you have to disable FileVault, and it doesnt appear that you can re-enable that either. BTW, I'd appreciate if someone can help to remove some files under /usr because "mount -uw" doesn't work on the "/" root directory. Thats a path to the System volume, and you will be able to add your override. 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. So from a security standpoint, its just as safe as before? Whos stopping you from doing that? Disabling rootless is aimed exclusively at advanced Mac users. Anyone knows what the issue might be? I am getting FileVault Failed \n An internal error has occurred.. 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) Boot into (Big Sur) Recovery OS using the . https://apple.stackexchange.com/questions/410430/modify-root-filesystem-from-recovery. Short answer: you really dont want to do that in Big Sur. So the choices are no protection or all the protection with no in between that I can find. It just requires a reboot to get the kext loaded. How you can do it ? Update: my suspicions were correct, mission success! I figured as much that Apple would end that possibility eventually and now they have. Please how do I fix this? 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).

I understand the need for SIP, but its hard to swallow this if it has performance impact even on M1. Assuming you have entered the Recovery mode already, by holding down the Power button when powering-up/rebooting. Apple has extended the features of the csrutil command to support making changes to the SSV. "Invalid Disk: Failed to gather policy information for the selected disk" network users)?

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. 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. If you choose to modify the system, you cant reseal that, but you can run Big Sur perfectly well without a seal. 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. She has no patience for tech or fiddling. Thank you so much for that: I misread that article! Would it really be an issue to stay without cryptographic verification though? A forum where Apple customers help each other with their products. I havent tried this myself, but the sequence might be something like You must log in or register to reply here. Additionally, before I update I could always revert back to the previous snapshot (from what I can tell, the original snapshot is always kept as a backup in case anything goes wrong). 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 solved this problem by completely shutting down, then powering on, and finally restarting the computer to Recovery OS. Howard. 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. Howard. 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.. Also SecureBootModel must be Disabled in config.plist. In your specific example, what does that person do when their Mac/device is hacked by state security then? Individual files have hashes, then those hashes have hashes, and so on up in a pyramid to reach the single master Seal at the top. Thanks, we have talked to JAMF and Apple. Thank you. Thank you. This workflow is very logical. I also expect that you will be able to install a delta update to an unsealed system, leaving it updated but unsealed. and disable authenticated-root: csrutil authenticated-root disable. Personal Computers move to the horrible iPhone model gradually where I cannot modify my private owned hardware on my own. The first option will be automatically selected. Thank you. Hi, (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. Every security measure has its penalties. Hoping that option 2 is what we are looking at. But he knows the vagaries of Apple. I use it for my (now part time) work as CTO. It effectively bumps you back to Catalina security levels. Howard. Before explaining what is happening in macOS 11 Big Sur, Ill recap what has happened so far. csrutil authenticated-root disable thing to do, which requires first to disable FileVault, else that second disabling command simply fails.

Maybe when my M1 Macs arrive. Well, privacy goes hand in hand with security, but should always be above, like any form of freedom. 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.

And we get to the you dont like, dont buy this is also wrong. csrutil authenticated-root disable returns invalid command authenticated-root as it doesn't recognize the option. 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. 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. If you can do anything with the system, then so can an attacker. Thank you yes, weve been discussing this with another posting. If you want to delete some files under the /Data volume (e.g. 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. You probably wont be able to install a delta update and expect that to reseal the system either. That is the big problem. I have now corrected this and my previous article accordingly. 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. Customizing or disabling SIP will automatically downgrade the security policy to Permissive Security. So much to learn. In the end, you either trust Apple or you dont. Im trying to implement the snapshot but you cant run the sudo bless folder /Volumes/Macintosh\ HD/System/Library/CoreServices bootefi create-snapshot in Recovery mode because sudo command is not available in recovery mode.

Just reporting a finding from today that disabling SIP speeds-up launching of apps 2-3 times versus SIP enabled!!! Sounds like youd also be stuck on the same version of Big Sur if the delta updates arent able to verify the cryptographic information. I will look at this shortly, but I have a feeling that the hashes are inaccessible except by macOS. Theres no encryption stage its already encrypted. Ive been running a Vega FE as eGPU with my macbook pro.

Its up to the user to strike the balance. SIP # csrutil status # csrutil authenticated-root status Disable If you zap the PRAM of a computer and clear its flags, you'd need to boot into Recovery Mode and repeat step 1 to disable SSV again, as it gets re-enabled by default. Click Restart If you later want to start using SIP once again (and you really should), then follow these steps again, except this time you'll enter csrutil enable in the Terminal instead. I suspect that quite a few are already doing that, and I know of no reports of problems. Encryption should be in a Volume Group. My MacBook Air is also freezing every day or 2. Ensure that the system was booted into Recovery OS via the standard user action. The MacBook has never done that on Crapolina. In Big Sur, it becomes a last resort. Yes, completely.
