Frequently Asked Questions

Why did OneDrive Files On-Demand stop working on my macOS Catalina?

Microsoft continuously updates the OneDrive application. Newer versions of the sync client and features like Files On-Demand require technologies that are only available in newer macOS versions, leading to dropped support for older systems like Catalina.

Can I still access my OneDrive files if I cannot upgrade my Mac?

Yes. You can access, edit, and download your files by logging into the OneDrive website via a web browser. Alternatively, you can search for and install an older, legacy version of the OneDrive client that still supports macOS Catalina.

How do I fix grayed-out files in my OneDrive folder on Mac?

Grayed-out files typically indicate a synchronization error or permission issue. Ensure the OneDrive app is running, check your internet connection, and verify that your user account has 'Read & Write' permissions for the OneDrive folder.

What is the difference between Files On-Demand and standard syncing?

Files On-Demand allows you to view all your cloud files in Finder without downloading them, saving hard drive space. Standard syncing downloads a local copy of every file directly to your computer.
