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 Thanx. SuccessCommand not found2015 Late 2013 yes i did. I understand the need for SIP, but its hard to swallow this if it has performance impact even on M1. Guys, theres no need to enter Recovery Mode and disable SIP or anything. The root volume is now a cryptographically sealed apfs snapshot. The MacBook has never done that on Crapolina. 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. I have more to come over changes in file security and protection on Apple Silicon, but theres nothing I can see about more general use of or access to file hashes, Im afraid.

Howard. There are a lot of things (privacy related) that requires you to modify the system partition Its my computer and my responsibility to trust my own modifications. Thank you. But why the user is not able to re-seal the modified volume again? The thing is, encrypting or making the /System read-only does not prevent malware, rogue apps or privacy invading programs. This ensures those hashes cover the entire volume, its data and directory structure. Yes, Im fully aware of the vulnerability of the T2, thank you. Even with a non-T2 chip Mac, this was not the correct/sufficient way to encrypt the boot disk. There is a real problem with sealing the System volume though, as the seal is checked against that for the system install. Your mileage may differ. 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. So it did not (and does not) matter whether you have T2 or not. Howard. [] APFS in macOS 11 changes volume roles substantially. 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. Once youve done it once, its not so bad at all. Apple has extended the features of the csrutil command to support making changes to the SSV. But I could be wrong. Then you can follow the same steps as earlier stated - open terminal and write csrutil disable/enable. Reduced Security: Any compatible and signed version of macOS is permitted.

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. mount -uw /Volumes/Macintosh\ HD. 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. 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.

You'll need to keep SSV disabled (via "csrutil authenticated-root disable") forever if your root volume has been modified. Great to hear! Thank you. BTW, I thought that I would not be able to get it past Catalalina, but Big Sur is running nicely. That is the big problem. 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. Apples Develop article. 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.

It is already a read-only volume (in Catalina), only accessible from recovery! You are using an out of date browser. I must admit I dont see the logic: Apple also provides multi-language support. I have the same problem and I tried pretty much everything, SIP disabled, adding to /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-#/DisplayProductID-*, This site contains user submitted content, comments and opinions and is for informational purposes only. 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. 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?

I booted using the volume containing the snapshot (Big Sur Test for me) and tried enabling FIleVault which failed. so i can log tftp to syslog. The System volume within a boot Volume Group is now sealed using a tree of cryptographic hashes, as I have detailed here. That said, would you describe installing macOS the way I did with Catalina as redundant if my Mac has a T2 chip? In addition, you can boot a custom kernel (the Asahi Linux team is using this to allow booting Linux in the future). Or could I do it after blessing the snapshot and restarting normally? Certainly not Apple. If you put your trust in Microsoft, or in yourself in the case of Linux, you can work well (so Im told) with either. Is that with 11.0.1 release?
