Product
Microsoft OneDrive
Device & OS
macOS 10.14.6 Mojave
Scenario
Attempting to run the OneDrive desktop client to synchronize files on an older Mac operating system.
Observed behavior
When an older, compatible version of OneDrive is installed, it briefly works but almost immediately auto-updates to a newer, unsupported version that refuses to open.
Before you start

Before attempting to restore older applications or upgrade your operating system, back up your locally stored files to an external hard drive to prevent any accidental data loss.

Solution 1Recommended

Upgrade macOS to a Supported Version

Updating your Mac to a newer operating system is the most reliable, long-term solution to ensure ongoing compatibility with the latest version of OneDrive.

Microsoft typically supports only the three most recent major versions of macOS. Because macOS 10.14 Mojave is no longer supported, upgrading your operating system is the only way to officially run the current OneDrive desktop client.

1
Check Mac Compatibility

Click the Apple menu in the top-left corner of your screen, select 'About This Mac', and check your Mac's model and year to see if it supports macOS Monterey or newer.

2
Open Software Update

Go to 'System Preferences' from the Apple menu and click on 'Software Update'.

3
Download and Install

If an upgrade is available, click 'Upgrade Now'. Follow the on-screen prompts to download and install the new operating system.

4
Reinstall OneDrive

Once the Mac restarts with the new macOS, download the latest version of OneDrive from the Mac App Store or Microsoft's website and sign in.

Frequently Asked Questions

Can I stop OneDrive from automatically updating on macOS?

Microsoft does not provide an official toggle to disable auto-updates for the Mac version of OneDrive. Blocking updates usually requires advanced network-blocking rules or third-party firewall software, which can be unreliable.

What is the last version of OneDrive that works on macOS Mojave?

Version 23.076 is generally reported as one of the last standalone versions to function on macOS 10.14.6 Mojave. However, due to forced updates, it is difficult to keep this version running permanently.

Can I access my OneDrive files on Mojave without the desktop app?

Yes, you can always log into OneDrive via a web browser like Safari or Chrome. This allows you to view, upload, and download your files without needing the desktop application installed on your system.

Will upgrading my macOS delete my locally synced OneDrive files?

No, updating your Mac operating system to a newer version will not delete your personal files or your OneDrive folder. However, it is always highly recommended to perform a Time Machine backup before running a major system upgrade.
