Hi maarten_780,
Welcome to the Microsoft Community.
It is an unfortunate fact that the new version of OneDrive for Mac only supports macOS 13 and newer version, but you can consider downloading an old version of OneDrive for Mac to see how it works.
First, please uninstall the OneDrive app on your Mac
And click here to download:
https://oneclient.sfx.ms/Mac/Installers/24.151.0728.0003/universal/OneDrive.pkg
The number 24.151.0728.0003, which stands for the OneDrive version number, was released in August 2024, so you can download it first to see if you can install it.
If that doesn't work, consider downloading an earlier version by replacing 24.151.0728.0003 in the link above with the version number you see in the release notes below.

Looking forward to any feedback you may have.
