OneDrive not working with macOS 13.7.8

OneDrive can continue to work on macOS 13.7.8, but only with the versions of OneDrive and Office that still support that macOS release. Once macOS 13 becomes unsupported, OneDrive and Office apps on that system will no longer receive any updates, including security fixes and new features.

Key points for this scenario:

1. macOS support and updates

• When macOS is not on a supported version, Office apps (including OneDrive) keep working but stop receiving updates.
• This means the currently installed OneDrive version that works on 13.7.8 can continue to be used, but it will not get future fixes or security updates once 13.x falls out of support.

2. Best practice

• To keep receiving mainstream support and security updates for OneDrive and the rest of Microsoft 365, the recommended path is to run a supported macOS version.
• If the iMac cannot be upgraded beyond 13.7.8, OneDrive can still be used in its last compatible version, with the understanding that it will eventually be frozen at that version.

3. If OneDrive stops working after an update

• If a newer OneDrive build no longer works on 13.7.8, installing an older, compatible build (the last version that supports that macOS) is required. For other Office apps on older macOS versions, this is handled by installing the last supported build (for example, Office 16.88 on macOS 12). The same principle applies to OneDrive.

4. Security considerations

• Continuing to use OneDrive on an unsupported macOS version means missing security updates both from macOS and from Office/OneDrive, which increases risk over time.

In summary, the existing OneDrive version that works with macOS 13.7.8 can continue to be used, but it will eventually stop receiving updates once that macOS version is no longer supported. For ongoing fixes and security updates, a macOS upgrade to a supported version is required.
