Howard. Thank you for the informative post. These are very early days with the SSV, and I think well learn the rules and wrinkles in the coming weeks. 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. My OS version is macos Monterey12.0.1, and my device is MacBook Pro 14'' 2021. 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 ? molar enthalpy of combustion of methanol. I havent tried this myself, but the sequence might be something like Also, type "Y" and press enter if Terminal prompts for any acknowledgements. As thats on the writable Data volume, there are no implications for the protection of the SSV. Sorted by: 2. Thanks to Damien Sorresso for detailing the process of modifying the SSV, and to @afrojer in their comment below which clarifies what happens with third-party kernel extensions (corrected 1805 25 June 2020).

Then I opened Terminal, and typed "csrutil disable", but the result was "csrutil: command not found". Why choose to buy computers and operating systems from a vendor you dont feel you can trust? Just great. The Mac will then reboot itself automatically. 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. Howard. Press Esc to cancel. In Config.plist go to Gui section (in CC Global it is in the LEFT column 7th from the top) and look in the Hide Volume section ( Top Right in CCG) and Unhide the Recovery if you have hidden Recovery Partition (I always hide Recovery to reduce the clutter in Clover Boot Menu screen). FYI, I found most enlightening. I must admit I dont see the logic: Apple also provides multi-language support. And your password is then added security for that encryption. I don't have a Monterey system to test. hf zq tb. 5. change icons tor browser apk mod download; wfrp 4e pdf download. Reinstallation is then supposed to restore a sealed system again. As explained above, in order to do this you have to break the seal on the System volume. In macOS Big Sur and later, your Mac boots from a cryptographically sealed snapshot. I am currently using a MacBook Pro 13-inch, Early 2011, and my OS version is 10.12.6. 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. I do have to ditch authenticated root to enable the continuity flag for my MB, but thats it. Once youve done it once, its not so bad at all. 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? Howard. Maybe when my M1 Macs arrive. But I wouldnt have thought thered be any fundamental barrier to enabling this on a per-folder basis, if Apple wanted to. Im not sure what your argument with OCSP is, Im afraid. @hoakley With each release cycle I think that the days of my trusty Mac Pro 5,1 are done. to turn cryptographic verification off, then mount the System volume and perform its modifications. This workflow is very logical. Putting privacy as more important than security is like building a house with no foundations. That is the big problem. I didnt know about FileVault, although in a T2 or M1 Mac the internal disk should still be encrypted as normal. So it did not (and does not) matter whether you have T2 or not. Every file on Big Surs System volume now has a SHA-256 cryptographic hash which is stored in the file system metadata. Just reporting a finding from today that disabling SIP speeds-up launching of apps 2-3 times versus SIP enabled!!! Im not fan of any OS (I use them all because I have to) but Privacy should always come first, no mater the price!. Thank you. Disabling SSV on the internal disk worked, but FileVault cant be reenabled as it seems. The file resides in /[mountpath]/Library/Displays/Contents/Resources/Overrides therefore for Catalina I used Recovery Mode to edit those files. System Integrity Protection (SIP) and the Security Policy (LocalPolicy) are not the same thing. And you let me know more about MacOS and SIP. If you need to install a kernel extension (not one of the newer System Extensions, DriverKit extension, etc. Howard. Period. 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. 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. SIP # csrutil status # csrutil authenticated-root status Disable Would you want most of that removed simply because you dont use it? However it did confuse me, too, that csrutil disable doesn't set what an end user would need. 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. Maybe I can convince everyone to switch to Linux (more likely- Windows, since people wont give up their Adobe and MicroSoft products). Ah, thats old news, thank you, and not even Patricks original article. I use it for my (now part time) work as CTO. Howard. Yes, Im fully aware of the vulnerability of the T2, thank you. Sealing is about System integrity. (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. It shouldnt make any difference. "Invalid Disk: Failed to gather policy information for the selected disk" Why do you need to modify the root volume? Guys, theres no need to enter Recovery Mode and disable SIP or anything. On my old macbook, I created a symbolic link named "X11" under /usr to run XQuartz and forgot to remove the link with it later. But I fathom that the M1 MacBook Pro arriving later this week might give it all a run for the money. It requires a modified kext for the fans to spin up properly. I understand the need for SIP, but its hard to swallow this if it has performance impact even on M1. Boot into (Big Sur) Recovery OS using the . 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. csrutil authenticated root disable invalid commandhow to get cozi tv. You have to teach kids in school about sex education, the risks, etc. Certainly not Apple. Thank you. Come to think of it Howard, half the fun of using your utilities is that well, theyre fun. It is dead quiet and has been just there for eight years. Howard. Its up to the user to strike the balance. But that too is your decision. The OS environment does not allow changing security configuration options. Well, its entirely up to you, but the prospect of repeating this seven or eight times (or more) during the beta phase, then again for the release version, would be a deterrent to me! A simple command line tool appropriately called 'dsenableroot' will quickly enable the root user account in Mac OS X. SIP I understand is hugely important, and I would not dream of leaving it disabled, but SSV seems overkill for my use. 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. twitter.com/EBADTWEET/status/1275454103900971012, apple.stackexchange.com/questions/395508/mount-root-as-writable-in-big-sur. https://arstechnica.com/gadgets/2020/11/apple-lets-some-big-sur-network-traffic-bypass-firewalls/. 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 mean the hierarchy of hashes is being compared to some reference kept somewhere on the same state, right? The root volume is now a cryptographically sealed apfs snapshot. However, it very seldom does at WWDC, as thats not so much a developer thing. Thats a path to the System volume, and you will be able to add your override. sudo bless --folder /[mountpath]/System/Library/CoreServices --bootefi --create-snapshot to create the new snapshot and bless it Why is kernelmanagerd using between 15 and 55% of my CPU on BS? Catalina 10.15 changes that by splitting the boot volume into two: the System and Data volumes, making up an APFS Volume Group. So whose seal could that modified version of the system be compared against? Click the Apple symbol in the Menu bar. As mentioned by HW-Tech, Apple has added additional security restrictions for disabling System Integrity Protection (SIP) on Macs with Apple silicon. 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) Encryptor5000, csrutil not working on recovery mode command not found iMac 2011 running high Sierra, Hi. What you can do though is boot from another copy of Big Sur, say on an external disk, and have different security policies when running that. and how about updates ? Updates are also made more reliable through this mechanism: if they cant be completed, the previous system is restored using its snapshot. A walled garden where a big boss decides the rules. Yes Skip to content HomeHomeHome, current page. 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. 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. However, you can always install the new version of Big Sur and leave it sealed. Apple disclaims any and all liability for the acts, Am I out of luck in the future? Howard. im trying to modify root partition from recovery. If I didnt trust Apple, then I wouldnt do business with them, nor develop software for macOS. 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? OCSP? Im sorry, although Ive upgraded two T2 Macs, both were on the internal SSD which is encrypted anyway, and not APFS encrypted. I like things to run fast, really fast, so using VMs is not an option (I use them for testing). Increased protection for the system is an essential step in securing macOS. Thank you, and congratulations. 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. That said, you won't be able to change SIP settings in Startup Security Utility, because the Permissive Security option isn't available in Startup Security Utility.
