OneDrive folder not found after upgrading to macOS 27

Question

OneDrive folder not found after upgrading to macOS 27

Nik Andric 0

Hi everyone,

I recently upgraded my Mac to macOS 27 (Golden Gate), and ever since the upgrade I’ve been getting an error from OneDrive that I can’t seem to resolve.

The exact error message is:

We couldn’t find your “OneDrive (2026-09-13 05:36:04 +0000)” folder in /Users/[USERNAME]/OneDrive (2026-09-13 05:36:04 +0000) Make sure this folder still exists in this location and click “Try Again,” or click “Stop Sync” to stop syncing this folder.

I can see OneDrive under my user folder at /Users/[USERNAME]/, so the OneDrive folder itself does exist. However, OneDrive seems to be looking for a folder with this strange timestamp appended to the name.

I’ve tried various tips and troubleshooting steps I’ve found online, but nothing has worked so far. I also contacted Microsoft support, but I haven’t received a response yet.

Has anyone run into this after upgrading to macOS 27 / Golden Gate? I’m especially interested in figuring out how to get OneDrive syncing again without accidentally losing or duplicating my existing files.

Any help would be hugely appreciated. Thank you!

The only fix for me seems to be running the Microsoft download not the App Store download. That is not my preference long term. Even reverting from Microsoft download to App Store after getting Microsoft download working is not a solution. Returns you to square one. Also interestingly, I had this problem on my M1 iMac but not on my M3 MBA. Both started from the same App Store OneDrive version.

Thanks, @Dick Watson . I agree. This isn’t my preference either. I’m inclined to switch to iCloud given Microsoft’s lack of support for the issue.

Hi @Nik Andric

Based on the error, I don't think OneDrive is saying that your current ~/OneDrive folder is physically missing. It appears to be looking for an older sync location whose name has a timestamp appended to it:

OneDrive (2026-09-13 05:36:04 +0000)

Since this started immediately after the macOS upgrade, treat it as a potentially stale OneDrive/File Provider sync reference rather than renaming or manually recreating folders.

On current macOS versions, OneDrive uses Apple's File Provider platform. The actual OneDrive sync root is normally managed under a location such as: ~/Library/CloudStorage/OneDrive-Personal, while the ~/OneDrive location you see in Finder may point to that managed sync location.

Before resetting anything, sign in to OneDrive on the web and confirm your important files are there. Also check the local OneDrive folder for files created or modified recently that may not have synchronized yet. Copy any such files to a temporary folder outside OneDrive. This matters because Microsoft's Files On-Demand troubleshooting guidance warns that resetting can remove local content that hasn't synchronized to the cloud.

Once you've confirmed the data is safe, use Microsoft's supported OneDrive reset procedure rather than manually deleting the timestamped folder:

Quit OneDrive from the menu bar.
Open Applications.
Control-click OneDrive → Show Package Contents.
Open Contents → Resources.
Run ResetOneDriveApp.command, or ResetOneDriveAppStandalone.command if that's the version provided.
Start OneDrive again and complete setup.

This procedure resets OneDrive on macOS. A reset disconnects the existing sync configuration and causes OneDrive to rebuild it.

When OneDrive asks for the folder location during setup, don't create another timestamped OneDrive folder. Microsoft's reset guidance recommends selecting the previous OneDrive syncing location where appropriate so unchanged files don't have to be downloaded again.

Also, don't click “Stop Sync,” delete the timestamped folder, rename ~/OneDrive, or move files around yet. Until we know whether that timestamped path contains any locally unsynchronized data, doing so could make recovery more confusing.

If the reset still produces the same timestamped-folder error, next check which File Provider location macOS currently considers active. In Terminal, run:

ls -la ~ | grep OneDrive
ls -la ~/Library/CloudStorage/

Please post the output with your username/personal information removed. This should show whether ~/OneDrive points to the current File Provider location and whether the timestamped folder still exists.

Also make sure you're running the latest OneDrive client before resetting. We recommend updating OneDrive before using the Mac reset procedure.

Hi @Allan Solomon Mejia , thank you very much for your help!

I completed the first step. The log from the ResetOneDriveApp procedure can be found below. Note the “operation not permitted” and “domain not found” errors, and kindly let me know if those are of concern.

I then attempted to reopen OneDrive. It says:

“OneDrive needs access to ‘/Users/USERNAME_REDACTED/Library/CloudStorage/OneDrive-Personal’. Please choose it to continue.”

Under the /CloudStorage/ directory, I see two folders:

OneDrive-Personal (8-15-24 5:48 PM)

OneDrive-Personal (9-20-26 7:34 PM)

The 9/20 folder appears to be more complete and recent. Should I choose that one? I also wonder why it has the timestamp attached to the folder name.

Thanks very much for your guidance. I will proceed with the next steps once I hear your advice on the above.

With appreciation,

Nik

Hello @Nik Andric

Thank you for posting the results. Don't select the 9/20 folder yet, even though it appears newer and more complete.

The two folders you now see:

OneDrive-Personal (8-15-24 5:48 PM)

OneDrive-Personal (9-20-26 7:34 PM)

are an important clue. On current macOS versions, OneDrive uses Apple's File Provider framework and stores its active sync location under: ~/Library/CloudStorage/

More than one OneDrive/File Provider location can remain on a Mac, particularly when different OneDrive installations or previous configurations are involved.

The timestamp therefore doesn't necessarily mean that the 9/20 folder is the one you should manually choose. We first want to determine which folder macOS currently recognizes as the active OneDrive File Provider domain.

Regarding the reset log, the Operation not permitted messages are worth noting, but don't conclude from those messages alone that your files are damaged. They show that parts of the reset script couldn't remove some OneDrive container/metadata locations. The fact that OneDrive subsequently starts and asks for access to a CloudStorage/OneDrive-Personal location suggests the reset got far enough to begin rebuilding the sync configuration.

Before selecting either folder, please do two checks.

First, make sure the important files are visible in OneDrive on the web. In particular, compare any files you've changed recently with what is online. Microsoft specifically warns that during certain Mac Files On-Demand reset scenarios, content that hasn't synchronized to the cloud can be lost.

Second, with OneDrive quit, open Terminal and run:

ls -la ~/Library/CloudStorage/

Then run this against each of the two folders:

xattr -l "$HOME/Library/CloudStorage/OneDrive-Personal (8-15-24 5:48 PM)" xattr -l "$HOME/Library/CloudStorage/OneDrive-Personal (9-20-26 7:34 PM)"

Please post the output, removing your username or other personal information if it appears.

Use xattr to identify the File Provider domain associated with a OneDrive folder. For example, the domain identifier can distinguish the standalone OneDrive client from the Mac App Store version.

Also, check that you don't accidentally have both OneDrive versions installed. Run:

mdfind 'kMDItemCFBundleIdentifier == "com.microsoft.OneDrive"'

and:

mdfind 'kMDItemCFBundleIdentifier == "com.microsoft.OneDrive-mac"'

The first identifier is for the standalone version, and the second is for the Mac App Store version. Only one version should be installed/configured at a time, because the two versions can't sync the same content simultaneously.

For now, please don't delete, rename, merge, or move either OneDrive-Personal folder, and don't manually copy the contents of one over the other. If the 9/20 folder contains locally generated File Provider placeholders while the older folder contains different local data, merging them manually could make the situation harder to untangle.

Once we see the xattr and mdfind results, we should be able to determine which OneDrive instance/File Provider domain macOS is trying to use and reconnect it cleanly, rather than guessing based on the timestamp.

Hello @Allan Solomon Mejia thank you for your continued help. I ran the above in Terminal; please find below the output with my username redacted.

MacBook-Air:~ USERNAME_REDACTED$ xattr -l "$HOME/Library/CloudStorage/OneDrive-Personal (8-15-24 5:48 PM)"

com.apple.macl:

MacBook-Air:~ USERNAME_REDACTED$ xattr -l "$HOME/Library/CloudStorage/OneDrive-Personal (9-20-26 7:34 PM)"

xattr: No such file: /Users/USERNAME_REDACTED/Library/CloudStorage/OneDrive-Personal (9-20-26 7:34 PM)

MacBook-Air:~ USERNAME_REDACTED$

MacBook-Air:~ USERNAME_REDACTED$ mdfind 'kMDItemCFBundleIdentifier == "com.microsoft.OneDrive"'

MacBook-Air:~ USERNAME_REDACTED$ mdfind 'kMDItemCFBundleIdentifier == "com.microsoft.OneDrive-mac"'

/Applications/OneDrive.app

Also, for what it's worth, in Finder on Mac, under my user file path, I do see a OneDrive folder, simply named OneDrive. Strangely enough, once I click on it, it appears as "OneDrive-Personal (9-20-26 7/34 PM)". Not sure if this is helpful information but thought I'd share.

Thank you; these results help quite a bit.

One clarification to my previous response: I had you run xattr directly against the timestamped folders under ~/Library/CloudStorage. I recommend checking the Finder-visible OneDrive path with xattr, so let's use that instead.

Your mdfind results are also helpful. The search for com.microsoft.OneDrive returned nothing, while com.microsoft.OneDrive-mac returned /Applications/OneDrive.app

com.microsoft.OneDrive-mac identifies the Mac App Store version of OneDrive. So this does not currently look like you have both the standalone and App Store versions installed.

The other observation you made is probably the most important one: Finder shows a folder simply named OneDrive, but when you open it, Finder identifies it as OneDrive-Personal (9-20-26 7:34 PM)

That suggests the Finder-visible ~/OneDrive location is associated with the newer File Provider location rather than the old 8/15/24 one. Still avoid deleting either folder until we've confirmed that association.

Please run this one command:

xattr -l "$HOME/OneDrive"

xattr -l ~/OneDrive identifies which OneDrive/File Provider version is configured for synchronization. For the App Store version, we would expect to see a File Provider domain containing:

com.microsoft.OneDrive-mac.FileProvider

You can also confirm the actual installed application's bundle identifier directly with Microsoft's documented command:

/usr/libexec/PlistBuddy -c 'Print CFBundleIdentifier' /Applications/OneDrive.app/Contents/Info.plist

Expect that to return com.microsoft.OneDrive-mac based on your mdfind result.

As for the earlier Operation not permitted messages from the reset script, don't try to fix those by manually deleting anything under ~/Library/Containers, Group Containers, or CloudStorage. Those locations are involved in macOS application/File Provider management, and manually removing them could make the current state harder to recover.

For the moment, please don't choose or delete either timestamped OneDrive-Personal folder. Once you post the output from xattr -l "$HOME/OneDrive we should have enough information to decide the next step.

If it confirms the com.microsoft.OneDrive-mac.FileProvider domain and Finder continues resolving ~/OneDrive to the 9/20/26 location, that would give us much stronger evidence that the newer location is the File Provider location currently associated with your App Store OneDrive installation. Then we can decide how to reconnect it without unnecessarily touching the older folder.

And please keep making sure anything important is in OneDrive online before we make changes. Resetting OneDrive can remove local content that hasn't synced to the cloud.

Thanks again for taking this carefully. Please post that xattr output, and we'll go from there.

@Allan Solomon Mejia many thanks for the continued help. Please see below the output from the requested commands:

MacBook-Air:~ USERNAME_REDACTED$ xattr -l "$HOME/OneDrive" xattr: No such file: /Users/USERNAME_REDACTED/OneDrive MacBook-Air:~ USERNAME_REDACTED$ /usr/libexec/PlistBuddy -c 'Print CFBundleIdentifier' /Applications/OneDrive.app/Contents/Info.plist com.microsoft.OneDrive-mac MacBook-Air:~ USERNAME_REDACTED$

Thanks, those results clarify things considerably.

First, the second command confirms that the OneDrive application currently installed on your Mac is the Mac App Store version: com.microsoft.OneDrive-mac

com.microsoft.OneDrive-mac is the bundle identifier for the Store version, while com.microsoft.OneDrive identifies the standalone version.

One clarification to my previous response: the xattr -l "$HOME/OneDrive" command isn't useful on your Mac because Terminal has now confirmed that this path does not exist:

xattr: No such file: /Users/USERNAME_REDACTED/OneDrive

So don't create that folder or change anything just to make that command work.

Instead, let's identify the actual File Provider folders and their metadata directly. Please run:

ls -la "$HOME/Library/CloudStorage"

and then:

find "$HOME/Library/CloudStorage" -maxdepth 1 -type d -name 'OneDrive*' -print

Please post the output from both commands.

Then, for each OneDrive path returned by the second command, run:

xattr -l "FULL_PATH_RETURNED_ABOVE"

You can drag the folder from Finder into Terminal after typing xattr -l if that's easier; macOS will insert the exact path and avoid problems caused by spaces or the timestamp in the folder name.

I want the exact paths rather than guessing from what Finder displays because modern OneDrive on macOS uses Apple's File Provider architecture. During File Provider migration, macOS can create a new OneDrive location while moving the previous data into a cache location.

Also, the File Provider domain for the Mac App Store version is:

com.microsoft.OneDrive-mac.FileProvider/OneDrive

If that appears in the extended attributes of one of these folders, it will give us much stronger evidence about which location belongs to the currently installed Store version.

For now, please don't delete, rename, or merge either timestamped OneDrive-Personal folder. Don't manually manipulate anything under ~/Library/CloudStorage, Containers, or Group Containers.

Inspect the OneDrive folders in CloudStorage, and where appropriate, unlink the Mac and reinstall a single OneDrive version. But because your newer timestamped folder appears to contain more recent data, identify which File Provider domain owns each location before we do that.

Please continue verifying that your important files are present on OneDrive online as well. Once you post the ls, find, and xattr results, we should be able to determine whether the 9-20-26 location is the active Store-version File Provider location and then choose the safest supported recovery path.

@Allan Solomon Mejia thanks, please see below the latest output. Hopefully it sheds some light on what's happening and the suggested path forward.

MacBook-Air:~ USERNAME_REDACTED$ ls -la "$HOME/Library/CloudStorage" total 24 drwxr-xr-x+ 5 USERNAME_REDACTED staff 160 Sep 3 2022 . drwx------+ 120 USERNAME_REDACTED staff 3840 Sep 17 20:12 .. -rw-r--r--@ 1 USERNAME_REDACTED staff 10244 Sep 20 19:34 .DS_Store drwx------@ 10 USERNAME_REDACTED staff 320 Aug 14 2024 OneDrive-Personal (8-15-24 5:48 PM) drwx------ 10 USERNAME_REDACTED staff 320 Sep 8 09:38 OneDrive-Personal (9-20-26 7:34 PM) MacBook-Air:~ USERNAME_REDACTED$ find "$HOME/Library/CloudStorage" -maxdepth 1 -type d -name 'OneDrive*' -print /Users/USERNAME_REDACTED/Library/CloudStorage/OneDrive-Personal (9-20-26 7:34 PM) /Users/USERNAME_REDACTED/Library/CloudStorage/OneDrive-Personal (8-15-24 5:48 PM) MacBook-Air:~ USERNAME_REDACTED$ MacBook-Air:~ USERNAME_REDACTED$ xattr -l "/Users/USERNAME_REDACTED/Library/CloudStorage/OneDrive-Personal (9-20-26 7:34 PM)" MacBook-Air:~ USERNAME_REDACTED$ xattr -l "/Users/USERNAME_REDACTED/Library/CloudStorage/OneDrive-Personal (8-15-24 5:48 PM)"
Allan Solomon Mejia 10,800 Reputation points

2026-09-22T00:11:54.09+00:00
Thanks. Yes, this does help. We now know for certain that there are two separate OneDrive-Personal directories under ~/Library/CloudStorage:

OneDrive-Personal (8-15-24 5:48 PM)

OneDrive-Personal (9-20-26 7:34 PM)

Combined with your earlier result showing com.microsoft.OneDrive-mac, we know the OneDrive application currently installed in /Applications is the Mac App Store version.

One important detail in your latest output: I can see the two xattr -l commands at the end, but I don't see their results.

Rather than run anything else, could you please run these two individually and paste everything Terminal returns after each one:

xattr -l "$HOME/Library/CloudStorage/OneDrive-Personal (9-20-26 7:34 PM)"

and:

xattr -l "$HOME/Library/CloudStorage/OneDrive-Personal (8-15-24 5:48 PM)"

If one produces something similar to com.apple.file-provider-domain-id: com.microsoft.OneDrive-mac.FileProvider/OneDrive, that is significant. The File Provider domain belongs to the Mac App Store version of OneDrive. The standalone version instead uses com.microsoft.OneDrive.FileProvider/OneDrive.

If a command produces no output, please mention that too and don't assume it failed.

Don't use the timestamps alone to decide which folder is correct. The 9/20/26 folder being newer and appearing to contain more current files is suggestive, but File Provider metadata is better evidence.

I recommend inspecting the OneDrive folders under CloudStorage and, where Finder identifies a folder as belonging to an old OneDrive version that is no longer installed, removing it through the supported Finder prompt rather than manually deleting CloudStorage content. Only one OneDrive version should be installed/configured for the same content.

So we're very close, but please don't delete, rename, merge, or select either timestamped folder yet.

Once we have the actual xattr output for both directories, we can compare it with your confirmed Store installation and decide whether the 9/20/26 directory is indeed the current File Provider location or whether we're dealing with stale/migrated CloudStorage entries.

And please continue checking that anything important is present on OneDrive online before making changes. Some reset scenarios can remove local content that hasn't synchronized to the cloud.

Thanks, @Allan Solomon Mejia ! See below for the output. I am almost positive that the 9/20/26 version is the correct, most up-to-date, but curious what this tells you. Appreciate the continued help.

2026-09-22T00:49:47.2933333+00:00

Thanks, this latest output is actually quite revealing.

The first command now returns:

xattr: No such file:

/Users/.../Library/CloudStorage/OneDrive-Personal (9-20-26 7:34 PM)

while the older location returns only:

com.apple.macl:

So don't manually select the 9/20 folder yet, even though it previously appeared to be the newer/current copy. Terminal is telling us that the exact 9/20 path we were testing no longer exists under that name.

Also, com.apple.macl by itself does not identify that folder as the active OneDrive File Provider location. Microsoft says the useful attribute for distinguishing the configured OneDrive version is com.apple.file-provider-domain-id, with the Store version normally identifying as com.microsoft.OneDrive-mac.FileProvider/OneDrive

Your earlier application check confirmed that the currently installed OneDrive application is the Store version (com.microsoft.OneDrive-mac), but we haven't obtained that corresponding File Provider attribute from either timestamped folder.

At this stage, rather than continue guessing paths in Terminal, follow Microsoft's supported procedure for this exact situation.

Click the OneDrive cloud icon in the macOS menu bar and, if OneDrive displays the location/version warning, choose Show in Finder. This should open the relevant CloudStorage location. Then, double-click each OneDrive folder shown there and look at the top of the Finder window. If macOS/OneDrive identifies one as belonging to a previous OneDrive version, a banner with a Delete button should appear for that obsolete folder. Use that button rather than manually deleting anything from ~/Library/CloudStorage.

If neither folder shows that banner/Delete option, open OneDrive preferences, go to Account, and choose Unlink this Mac. Unlinking in this procedure doesn't delete your cloud data; you then configure the single installed OneDrive version again.

Before doing that, make sure the files you care about are visible in OneDrive online. That's particularly important in your case because we've already seen inconsistent local paths following the macOS upgrade.

If you do need to reset OneDrive afterward, use the reset script supplied inside the installed OneDrive application rather than manually changing CloudStorage: Applications → OneDrive → Show Package Contents → Contents → Resources → ResetOneDriveApp.command

One other thing: don't manually merge the 8/15 and 9/20 folders. Only one version of OneDrive should be installed/configured for the same content on a Mac.

So my next question is much simpler: when you open the OneDrive folders through Finder, does either Finder window show Microsoft's banner with the Delete button?

If yes, please tell us which timestamped folder shows it before clicking anything. If neither does, tell us that as well, and we'll use the unlink/reconfigure route.

@Allan Solomon Mejia I'm not sure I'm following. The reason I reached out is because I cannot click the OneDrive cloud icon in the macOS menu bar and choose Show in Finder. The only options are "Close OneDrive" and "Stop Sync". It's telling me that it can't find the 2026-09-13 location, as above in my original question. Oddly enough the folder "OneDrive-Personal (9-20-26 7/34PM)" does show up after I click on OneDrive under Finder.

I wish I could follow the above, but alas I cannot. Choosing either Close OneDrive or Stop Sync does absolutely nothing.

Re: "So my next question is much simpler: when you open the OneDrive folders through Finder, does either Finder window show Microsoft's banner with the Delete button?" can you please help me understand what you mean by banner?

Thanks in advance for your guidance on next steps. I'm a bit at a loss...

To reiterate, this only happened recently when I updated to the latest MacOS. Before that OneDrive was syncing perfectly, with files as recently updated as last week.

Thanks for clarifying. Please disregard my suggestion about looking for a Finder banner. That procedure applies to a different OneDrive duplicate-version scenario, and your OneDrive client clearly isn't presenting those options.

Since the supported reset has already failed to repair the File Provider registration, the next sensible step is to reinstall the OneDrive client, after first confirming your important files are available in OneDrive online and separately backing up anything that exists only in the 9/20 folder.

After reinstalling, let OneDrive re-establish its File Provider location.

If the reinstall prompts you to choose an existing folder/location, stop and post a screenshot before selecting one. That will tell us whether OneDrive itself recognizes the 9/20 location.

@Allan Solomon Mejia Thanks; apologies but you lost me a bit. 1) In what way did the supported reset fail to repair the registration? I don't believe we tried resetting anything yet? 2) How would you recommend I reinstall OneDrive? Do I simply delete it from my Applications and install a new version? If so, which version do you recommend.

One additional piece of important information: I just checked the file path of my OneDrive folders, and it's definitely /Users/my_username/Library/CloudStorage/OneDrive-Personal (9-20-26 7:34 PM)/Documents/. What's odd however is that OneDrive is trying to find a "2026-09-13" version. I feel like something just got corrupted, directory-wise, during the latest MacOS update. Knowing this, how should I proceed?

Hello @Nik Andric

No worries. Just to clarify, you did run the OneDrive reset earlier in this thread using ResetOneDriveApp.command

That reset produced the "Operation not permitted" messages, so I don't recommend repeating it.

For the reinstall, since we've confirmed you're currently using the Mac App Store version (com.microsoft.OneDrive-mac), I suggest trying the standalone OneDrive version downloaded directly from Microsoft. Another user in this same thread reported that switching from the App Store version to Microsoft's direct download resolved the issue.

Remove/uninstall the current OneDrive app from Applications, then install the standalone version from Microsoft. Before doing so, make sure your important files are available on OneDrive online and back up any local-only files. Don't delete either timestamped CloudStorage folder yet.

@Allan Solomon Mejia got it. One more piece of information that might be helpful. I actually did a comparison of the 8-15-24 and 9-20-26 folders and some of the files therein overlap, some not.

If I proceed with uninstalling OneDrive, is there a risk of it deleting the two folders under CloudStorage? At the risk of wasting 27GB of space, should I save the contents elsewhere?
Allan Solomon Mejia 10,800 Reputation points

2026-09-22T02:25:34.2433333+00:00

Yes, given that you've found files that don't overlap between the two folders, save both folders somewhere else before uninstalling OneDrive.

Uninstalling the OneDrive application normally doesn't delete your files from OneDrive online, but with the unusual File Provider/CloudStorage state on your Mac, I wouldn't take any chances with potentially unsynced local files.

Copy the contents of both to a location outside ~/Library/CloudStorage, preferably an external drive if you have one. Keep the two backups separate so you can compare them later.

Once you've confirmed those copies are readable and your important cloud files are visible on OneDrive online, you can uninstall the App Store version and install the standalone OneDrive version.

I was facing the same issue. Downloading OneDrive directly from Microsoft, not the Mac App Store worked for me - https://support.microsoft.com/en-us/onedrive/reinstall-onedrive

Thanks very much, @Piyush Jha !

@Allan Solomon Mejia based on the below output, might Piyush' suggestion make sense as a next step? I want to ensure that we see your suggestions through, and flag this as a potential path forward. Appreciate you both!

Just reinstalling did not work for me. I had to follow the instructions shared below by @Allan Solomon Mejia and it worked. Thanks Allan.

I just made the mistake of revisiting this. Uninstalled Microsoft downloaded OneDrive. Installed Store OneDrive. Same folder not found problem. Uninstalled Store version. Installed Microsoft download version. "OneDrive Update Required Your OneDrive files were managed by a newer version of OneDrive. Please update to the latest version to access your files. No data has been lost." So now neither version works. On my M1 iMac. Store version continues to work just fine on my M3 MBA.

Sigh.

Luckily OneDrive on the Mac is just a convenience aid to me and not vital. Maybe Microsoft will fix this sometime before MacOS 28?!?!!?@?

Answer 3

I ran into a related issue on macOS 27 and the workaround of installing it from microsoft page worked.

Setup:

MacBook Air M3 (2024), macOS 27.0.1 (Build 26A434)
OneDrive 26.168.0830 from the Mac App Store
Internal startup disk, APFS case-insensitive (verified with "diskutil info /")

Problem:

OneDrive suddenly stopped syncing. After that, setup could no longer be completed: after signing in, OneDrive didn't suggest a default location but immediately asked me to choose one, then said the location must not be on a removable drive or a case-sensitive volume. Neither was true for this internal disk. There was no OneDrive folder in ~/Library/CloudStorage anymore, while Dropbox, Google Drive and Nextcloud kept working there.

What did NOT help:

ResetOneDriveApp.command
Removing all OneDrive containers, group containers, Application Support folders and preferences
Deleting the app, restarting and reinstalling it from the App Store

What DID help:

I removed the Mac App Store version as described by Allan and installed the standalone version from Microsoft's website instead. Setup then worked right away, the OneDrive folder was created in ~/Library/CloudStorage, and syncing works again.

I'm not sure whether the App Store version itself has a bug on macOS 27, or whether the standalone version simply creates a fresh File Provider registration that avoids the one broken by the upgrade. Either way, switching to the standalone version solved it for me. Make sure not to have both versions installed at the same time.

Yesterday (27-10-2026), I updated to 27.2 (MacBook Air M4 2025) and lost contact with my OneDrive sync.
I just checked my OneDrive online (Sharepoint), and it appears that my latest files are up-to-date there.

If I may ask Kolja Köln and others, what do you suggest I do exactly?

So mission accomplished. First, I confirmed my files on my OneDrive (SharePoint) were current; then I simply deleted (in Finder) the synced OneDrive folder on my Mac, emptied the trash, reinstalled Office 365 from MS, restarted my Mac, started the OneDrive app, and logged in to my business account. Voila! 🤠
