How to Fix OneDrive Files Not Opening on an Older Mac
Question details
The user is unable to open local OneDrive files because the OneDrive application was uninstalled and cannot be reinstalled due to OS incompatibility on an older Mac.
- Product
- Microsoft OneDrive
- Device & OS
- macOS Big Sur
- Scenario
- Attempting to reinstall the OneDrive application and open local synced files on an older Mac operating system.
- Observed behavior
- The OneDrive application fails to reinstall because the OS is no longer supported, preventing locally stored OneDrive files from opening.
Ensure you have a stable internet connection and your Microsoft account credentials ready so you can access your cloud files via a web browser.
Access and Download OneDrive Files via the Web Browser
Since the desktop application is incompatible with your current macOS, the most reliable method is to access your files directly through the OneDrive website.
Microsoft OneDrive officially supports only the three most recent major versions of macOS. If your Mac is running an older version like Big Sur, the newest desktop app will not install. Using the web version allows you to bypass OS limitations and safely download your files.
Open your preferred web browser on your Mac, navigate to the official OneDrive website (onedrive.live.com), and sign in using your Microsoft account credentials.
Browse through your folders in the web interface to find the specific documents or files you were trying to open locally.
Select the files or folders you need, click the 'Download' button on the top toolbar, and save them to a local directory on your Mac (such as your Downloads or Documents folder) to open them.
Install a Compatible Older Version of OneDrive for Mac
If you strongly prefer using the desktop application, you can try finding and installing a legacy version of OneDrive that supports your older macOS.
Easily Open and Edit Downloaded Office Files on Older Macs
If your Mac is too old to support the latest Microsoft 365 or OneDrive updates, WPS Office provides a lightweight, highly compatible alternative. You can easily edit the files you download from OneDrive without upgrading your macOS.
- 1. Download WPS Office: Visit the official WPS Office website and download the Mac version.
- 2. Install the Application: Open the downloaded installer and follow the on-screen instructions to install WPS Office on your Mac.
- 3. Open Your Files: Launch WPS Office, click 'Open', and select the documents you downloaded from the OneDrive website to start editing immediately.
Frequently Asked Questions
Why did OneDrive suddenly stop working on my older Mac?
Microsoft updates OneDrive regularly and only supports the three most recent major versions of macOS. When Apple releases a new macOS, the oldest supported version is dropped, which can prevent OneDrive from updating, installing, or syncing on older systems.
Can I edit my OneDrive documents without the desktop application?
Yes. You can edit documents directly in your web browser using Microsoft Office for the Web, or you can download the files to your local drive and open them using a compatible local office suite like WPS Office.
Are my files deleted if I can't reinstall OneDrive?
No, your files are completely safe. Any file that was successfully synced before you uninstalled the application remains securely stored in your Microsoft cloud account, accessible via any web browser.
Will updating my macOS fix the OneDrive installation issue?
Yes, if your Mac hardware supports it. Upgrading your Mac to one of the three most recent macOS versions (e.g., macOS Sonoma, Ventura, or Monterey) will allow you to install the latest version of OneDrive without any issues.
