Hi Spaltzer,
Thank you so much for reaching out to the Microsoft Community. I'm really sorry to hear you're having trouble installing OneDrive on macOS Monterey 12.7.6. I know how frustrating that can be, and I’m here to help you as best I can.
Right now, the latest version of OneDrive requires a newer version of macOS. But don’t worry — there’s a workaround! You can still use OneDrive by installing an earlier version that works well with your current system. Here’s a direct link to download it:

Once installed, I recommend turning off automatic updates to prevent OneDrive from upgrading to a version that might not be compatible with your macOS.
Also, if you’d like Microsoft to consider supporting macOS Monterey again in the future, I’d really encourage you to share your thoughts on our official feedback portal: Ideas · Community
Your voice truly matters, and your suggestions help shape the future of our products for everyone.
Feel free to share with me updates on how things are progressing after you've completed the aforementioned steps. If you have any questions or need clarification, please do not hesitate to contact me. I would like to do my best to help you!
If you found my response helpful, marking it as an answer would be useful for others facing similar situations. Wishing you a smooth day ahead!
Sincerely,
Jeanie-H - MSFT | Microsoft Community Support Specialist.
