One Drive Stopped Working since April 7th, 2023 and running with MaC OS catalina 10.15.7

I am having exactly the same problem, and none of these solutions have worked to fix the problem.

Just adding to the chorus: I have the same problem. Catalina 10.15.7.

No cloud icon in toolbar.

From app folder, computer seems to register that I've selected for opening, but nothing happens.

Initially I thought that perhaps app needed updating, so I downloaded latest. It wouldn't open either.

Then I saw the recent discussion threads like this one that confirm OneDrive is now incompatible with Catalina. I sincerely thank all of you who have gone through multiple steps and mountains of frustration only to confirm that none of these steps are working.

Awaiting solid solution from Microsoft.

This 'solution' (well, hack actually) worked for me:

Steps are basically: download a previous version of OneDrive. Annoyingly, the download links in the article with the solution now all point to the new, 'broken' version, so you can't download it from there. Fortunately, there's a guy who has posted every single onedrive version yet:

https://hansbrender.com/all-onedrive-versions/#tabmac

There, look for version 23.054.0313.0001 and download it.

While you download, make sure you already open activity manager and force quit the Standalone Updater that keeps on aggressively rearing its ugly head like a digital groundhog. It needs force quitting twice otherwise it will not take the hint.

After download, if you cannot find the package file, look in your rubbish bin – the Standalone Updater may have already moved the installer to the bin. It really is Clippy's evil older sibling.

Switch off wifi to avoid any updates.

Then install the package. It will not do so by clicking on it, because it's an unsigned update, so you will have to right-click and insist it installs.

While installing, keep an eye out on the activity monitor to stomp down any attempts by the Standalone Updater or the OneDrive Auto-updater to disrupt the process.

After installing, go through the terminal steps in the article first, and THEN switch on wifi and fire up onedrive. Make sure it's the right version, though, by calling up the info on the app by clicking on it once and then hitting CMD-I. If it says 23.054.0313.0001 then it should work.

I am now enjoying my working older version, which is happily processing the many updates of the last days. I hope you will too!

Thanks Ravikumar, for your support

But, I did the 4 options with no success , even with the installation of a fresh OneDrive software and nothing.

It is rare and just happened since april 7th, 2023.

Best regards

I am having the same issues described above, and I have tried solutions suggested above and also those listed in top comment thread here: https://www.reddit.com/r/macsysadmin/comments/12dx8wo/onedrive_app_will_not_launch/

This issue started in the last few days

When I wipe/manually uninstall and re-install OneDrive, it takes me through the setup/installation assistant and is open very briefly. Then once I have finished the setup wizard it closes, the app in my Applications folder briefly disappears and is replaced (???), and then it won't launch/open again after that. No syncing available, and the OneDrive app does not appear in my menu bar or Activity Monitor when I try to open it.

I am running Mac OS 10.15.5 on a mid-2019 Macbook Pro.
