I am having problems syncing on the Mac with Tahoe 26

Question

I am having trouble syncing computer files with OneDrive

Answer 1

Hi Sallie Orbas,

Thanks for reaching out to Microsoft Q&A Forum. I understand how frustrating it can be when your files aren’t syncing properly with OneDrive, especially if you rely on it to keep everything up to date across devices.

To start, here are a few common checks that often resolve most OneDrive sync issues:

• Make sure OneDrive is running and signed in. You should see the cloud icon in the system tray (near the clock). If it’s missing or shows a warning, open OneDrive and sign in again.
• Check that sync isn’t paused. Click the OneDrive icon > Settings, and confirm syncing is active.
• Verify that you have enough storage space available both on your computer and in your OneDrive account.
• Restart OneDrive (or restart the computer) to clear any temporary sync glitches.

If the issue continues, the next recommended step is to unlink and relink OneDrive:

1. Click the OneDrive icon > Settings > Account
2. Select Unlink this PC
3. Restart your computer
4. Sign back in to OneDrive and allow it to resync your files

You can also review Microsoft’s official troubleshooting guide here, which explains common sync errors and icons in detail: https://support.microsoft.com/office/fix-onedrive-sync-problems-0899b115-05f7-45ec-95b2-e4cc8c4670b2

Hopefully my response gives you some useful directions toward fixing this. In case you need my help, feel free to let me know.

On tahoe 26 the mac one drive client stalls when its file‑provider extension loses the sandbox grant… it looks like sync but it’s the extension not getting the handoff. toggling the onedrive file‑provider in system settings → extensions forces a fresh grant and the sync wakes up.
