Yes, and no way.

I tried to delete the snapshots as root user, and same error "no enough privileges".
Yeah, that error appeared to me too for the last snapshot. The other two were deleted successfully (using `diskutil`, `tmutil` didn't work)

Finally found a fix! Deleting snapshots using `tmutil` didn't work but I deleted them with `diskutil` from Recovery: `diskutil apfs listSnapshots <Macintosh HD's disk id>` and then `diskutil apfs deleteSnapshot <disk id> -uuid <snapshot uuid from the previous command>` for every snapshot. I had 3, two of them were deleted and one returned "insufficient privileges" but it doesn't matter, now everything works. Do it at your own risk, I don't know whether it will work on your Mac.
Can confirm this fixed it after I still got errors. This was the exact answer I searched for in the OP. Thank you so much!

Wintendo installed, and good lord Windows has not got any better.

I was not able to remove any of the snapshots, as I got insufficient privileges on all three of them, even using sudo. I have three snapshots that begin with "com.apple.os.update-", two which contain numbers and letters after, and one which ends in "MSUPrepareUpdate". Did you delete them using macOS recovery or Single-User Mode, or in regular macOS?

Edit: My bad, I just say that you mentioned from Recovery (big facepalm). I will try again from recovery

When I went into recovery, the ID of my Macintosh HD was different from when in normal macOS. On normal macOS, Macintosh HD is listed as disk1s1, but in Recovery it showed as disk3s1. I was able to delete the first two and had insufficient priviledges on the last one as you mentioned. When I rebooted into regular macOS from recovery, I ran "diskutil apfs listSnapshots disk1s1" and the three snapshots were there again, and Boot Camp gave me the same error it cannot partition. Did you experience something like that? I'm running macOS Big Sur Developer Beta 2

Weird, mine were gone after I deleted them. I remember after I deleted the 2 snapshots I made a test partition (still from recovery) and deleted it to see if it worked. Try that too

I’m stuck with this exact situation except it also failed in recovery mode. Insufficient privileges for all three.

I just saw your response, and I didn't try to make the partition. What weirdly worked for me was to delete the snapshots and reboot to macOS three times. I do not know if it was the three times that worked, or something different that I did on my last attempt. The only thing different I did was to eject a drive called "CCCOMA_X64FRE_EN-US_DV9" in Disk Utility before rebooting into Recovery. Anyways, thank you so much for your help!

EDIT: I also mounted the Macintosh HD (Data) volume while in recovery along with the already mounted Macintosh HD. I highly doubt this did anything as the snapshots were not located in the Data volume. I'm just putting it here if it helps someone.

I am having the exact same problem in Beta 2. Managed to delete 2 snapshots in Recovery Terminal using the diskutil command, but the 3rd one says “insufficient privileges”. Annoyingly, this is the one that says “NOTE: This snapshot limits the minimum size of APFS Container disk2”. I suspect this is in some way related to the problem.

For info I turned off Time Machine automatic backups in macOS before rebooting to Recovery

UPDATE: this fixed it, deleting those 2 snapshots in Recovery Terminal worked for me

In my Disk Utility there's a UDF volume called "CPBA_X64FRE_EN-US_DV9"

Hello! I just saw your posts and I'm glad you got your Boot Camp working. I'm believe that your volume "CPBA.." is for a different version of Windows that I'm using. I was using the Windows 10 education edition as that is the version I have a license for. By looking up the volume, it does appear to be the same thing that I experienced, but with a different name because of a different version. Did ejecting before rebooting work for you, or did you not eject it?

Hi. I'm reviving this thread because I think because I think the solution to the problem I am having is in here, but I am not confident enough to go ahead and try without a bit more advice. I hope that's OK. If anyone here is able to help me, I would be really grateful.

I am of course now running the full release of Big Sur (11.0.1), rather than the beta.

I am having the same problem as others in the thread: Boot Camp failing to partition the disk. I haven't been able to fix the problem using First Aid in Disk Utility (I am not experienced, though, and have perhaps missed something). I have never used Time Machine, but there is seemingly one System Snapshot on the device (com.apple.os.update-779BDF1556C6F68), presumably generated during the Big Sur install. I would like to know if it would be safe to try and delete that snapshot, seeing as someone earlier in the thread mentioned that the OS may be booted from it. Indeed, Disk Utility seems to indicate this, but only after running First Aid. Please let me know if you do or don't understand what I mean.

Thanks.

I remember that when I deleted my snapshots, I deleted all of the `com.apple.os.update` snapshots, except for the `com.apple.os.update-MSUPrepareUpdate` snapshot, as it would not let me delete that one. As far as that being safe, it did not affect my computer in any way, but I am not 100% sure that it would be the same for you. From my understanding (someone correct me if I'm wrong), the update snapshot is created before an update, similar to a Time Machine snapshot. Sorry if this was not of much help, but there is not that much information I could find regarding the update snapshots.

Thanks. I'm leaning towards just trying it. The fact that Disk Utility looks like this makes me apprehensive, though:

Like I said, this is how it looks and stays after running First Aid. If I try using Boot Camp again, I get to the partition failed alert, but then everything looks more normal in Disk Utility, with Macintosh HD not greyed out and the snapshot just sitting there looking more expendable. Not sure what to make of it, tbh.

That's weird. For me, the snapshots did not appear in Disk Utility, but rather in the Terminal while typing `diskutil apfs listSnapshots <volume>`, and about 3 of them appeared there. If you end up trying, good luck, and may all your files be intact!

Thanks. It appears to be the one and only snapshot on my system. But yeah, at the moment it is seemingly mounted instead of the normal Macintosh HD. When I run `diskutil apfs listSnapshots` on Macintosh HD (disk1s5) I get: "Error getting list of snapshots for APFS Volume: A disk with a mount point is required (-69854)". I have read and been told elsewhere that the disk not being mounted is normal in Big Sur, though, but I don't really understand. And like I said, this changes after I run and fail Boot Camp. 🤷‍♂️

Anyone out there got any more thoughts on how I can get the partition happening?

So I went ahead and tried to delete that single snapshot in Recovery and, yeah, it's the insufficient privileges one. I tried Boot Camp again anyway after restarting and unfortunately no luck— it still fails when partitioning.

Not sure what to try now.

You can try contacting Apple support. Usually, the first person that answers just gives generic answers, but with a very specific and technical problem like that, they transfer the call to someone that really knows what they are doing. I did not contact Apple support because I was running the developer beta and Apple refuses to give support to beta users, as the software is still "in development".

I just found old photos I took of my screen before I deleted my snapshots. Do the snapshots say they are purgeable? Here's what it looked like. I don't know if it would help, but I'll share anyway.

Nope, it's just the one snapshot, and it's not purgeable. I think the problem is that I must have deleted my old (I think pre-APFS) Windows partition using Disk Utility, or at least done it wrong somehow. Unless you can think of a fix for this off the top of your head, I'm just waiting for a call from Apple on Monday. Cheers!

So, were you able to fix your problem? I have all the same situation, with one single non-purgable Snapshot "com.apple.os.update-55..." and tried everything I could - from trying to delete Snapshot using terminal like FrankFabregat said and recovery mode(insufficient privileges) to complete reinstalling of MacOS. First Aid tool didn't help either.

I got the same problem. The one snapshot disk is not purgeable to delete. Have you finally solved your problem? How? It will be appreciated for the share.
