Mac: OneDrive Couldn't Start: Please restart your computer and try again

It seems clear that there is no single solution that works for everyone and that OneDrive currently has a range of issues, both in standalone and O365 versions. Could we please have information on when this is likely to be fixed.

I am hoping this reply (3rd time trying to post) makes it...

I blew away everything and I'm seeing this now:

I can confirm that this morning, when version 26.158.0816.0003 deployed (I believe through automated updates that I didn't initiate), the issue was resolved.

I think we can all agree that a "reset" is not a resolution, it's a "we absolutely can't wait to fix" stop gap measure. Too often this response is used to correct what is poor quality control and an unguarded software failure. This is now a widely known issues, there is no excuse for the release to still be rolling out (https://learn.microsoft.com/en-us/sharepoint/sync-release-notes?tabs=macos) when it is clearly defective. We can't be the only people to have encountered this.

What is interesting is that in my personal life, version 26.158.0816.0003 is deployed and is not exhibiting this behavior.

I can confirm this worked for me and several other employees, though a slightly more involved fix. 

Identify what folders they have syncing before running 

Step 1 — Fully quit OneDrive 

Click the OneDrive cloud icon in the menu bar → Quit OneDrive 

Open Activity Monitor (Spotlight → "Activity Monitor") and confirm nothing named OneDrive is still running; force-quit any strays 

Step 2 — Get to the reset scripts 

Open Finder → Applications 

Right-click OneDrive → Show Package Contents 

Navigate to Contents → Resources 

Step 3 — Remove cached credentials 

Double-click RemoveOneDriveCreds.command 

A Terminal window opens and runs briefly, then closes 

Step 4 — Run the full reset 

Still in that same Resources folder, double-click ResetOneDriveAppStandalone.command 

Terminal opens again and clears out local app state, sync database, and the local OneDrive folder registration 

Step 5 — Relaunch and set up fresh 

Open OneDrive from Applications (or Spotlight) 

Sign in with the Altus account 

Since you're mid-tenant-spinout, double check it's authenticating against the right tenant before you pick folders to sync 

Choose sync scope (Files On-Demand vs. sync everything) and let it re-download 

Incredible - will be removing team from sharepoint - everyone is messed up cannot access critical shared files - I have tried the below and it worked and 1 day later it unlinked again - just not worth the hassle, we now have arcane file names "2" duplicatoin of stings in names, folders we cannot delete to resync loss of multuple sharepoints - I have instructed my entire team to stop working. 

For me this file did not exist:

"/Applications/OneDrive.app/Contents/StandaloneUpdater.app/Contents/MacOS/OneDriveStandaloneUpdater"

Reset ondrive script worked but a new error appears today.

The route folders of my sharepoint works however consitutent folders are syncing from a seperate location on the filesystem not user/library/Cloudstorage/whatever onedrive but rather inside 

…/Group Containers/XXXXXX.OneDriveStandaloneSuite/XXXXX.noindex/…/XXXXXX - Documents/my folder

for me a hard reset seemed to have done the trick, but it does remove all your synced drives unfortunately.. 

Run from Terminal:
/Applications/OneDrive.app/Contents/Resources/ResetOneDriveAppStandalone.command

A clean-reinstall approach helped me to get it working even at the same build 26158.0816.002 (downloaded from official Microsoft site). Files were retained, no need to worry when it offers to Erase and Connect again. Still recommend backing up.

Instruction:

1. Quit OneDrive (Activity Monitor force-quit if needed).
2. Drag OneDrive.app to Trash (don't empty yet).
3. Remove leftover support files via Terminal:

• rm -rf ~/Library/Application\ Support/com.microsoft.OneDrive
  rm -rf ~/Library/Application\ Support/OneDrive
  rm -rf ~/Library/Caches/com.microsoft.OneDrive rm -rf ~/Library/Application\ Scripts com.microsoft.OneDrive* 
  rm -rf ~/Library/Application\ Scripts/*.OneDriveStandaloneSuite

4. Restart the Mac (clears any lingering File Provider registration state tied to the old install).
5. Download a fresh installer directly from microsoft.com/onedrive (not the App Store) and install.
6. Sign back in and reconnect folder.

What worked for me was switching to the insider preview and then invoking the updater via the terminal:

"/Applications/OneDrive.app/Contents/StandaloneUpdater.app/Contents/MacOS/OneDriveStandaloneUpdater"

Fixed it in 5 mins

same issue here, very annoying.
