If you rely on OneDrive for critical work or sensitive data, you should not run it on macOS 10.13.6.

Recommendation:

Usable but deprecated. OneDrive on macOS 10.13.6 is suitable for light cloud storage access on legacy hardware (e.g., 2012–2017 Macs) where upgrading the OS is impossible due to hardware or software constraints. However, for daily professional use or environments requiring security compliance, upgrading both macOS and OneDrive is strongly advised.

Last updated: Based on Microsoft’s support lifecycle policies as of 2025. Microsoft may fully block older OneDrive clients to the Microsoft 365 service at any time.

Running OneDrive on macOS 10.13.6 (High Sierra) is no longer officially supported by Microsoft, creating a significant hurdle for users on older hardware. While the software was once compatible, the current ecosystem requires specific workarounds or older installers to function. The Compatibility Gap onedrive for macos 10.13.6

Microsoft officially ended support for macOS 10.13 in 2021. Currently, OneDrive for macOS requires one of the three most recent versions of macOS (currently macOS 12 Monterey and newer). When a macOS version becomes four years old, Microsoft typically ceases updates and blocks new sign-ins for that OS version to maintain security standards like APFS integration and File Provider API requirements. How to Get it Working

If you must use OneDrive on High Sierra, you cannot download it from the Mac App Store, as it will only offer the latest version. Instead, you must use a standalone legacy installer:

Version 21.002: This is widely considered the last stable version that fully supports macOS 10.13.6. Installation Process: Uninstall any existing versions of OneDrive.

Download the standalone OneDrive 21.002 pkg installer from Microsoft's servers (if still hosted) or verified mirror sites.

Disable automatic updates immediately after installation, or the app may attempt to "self-update" to a version that crashes on High Sierra. Critical Limitations & Risks

Security Vulnerabilities: Legacy versions do not receive security patches, leaving your data and system exposed to exploits that newer versions have fixed.

"Files On-Demand" Issues: High Sierra uses an older implementation of Apple's file system. You may experience sync hangs or "error -50" when trying to download files that are marked as online-only. Published: October 2023 (Updated for Legacy Support) If

Authentication Loops: Many users report that even with the correct version installed, the app may enter a constant "Sign-In" loop because the underlying security protocols used for login are no longer accepted by Microsoft’s modern servers. Recommended Alternatives

If the legacy client fails to sync, these methods are more reliable for older Macs:

Web Interface: Using OneDrive through a modern browser (like a recently updated version of Chrome or Firefox that still supports 10.13) remains the most stable way to access files.

Third-Party Sync Tools: Apps like rclone or InSync often maintain compatibility for older operating systems longer than the official first-party clients.

Hardware Limitations: If your Mac supports it, consider using a patcher tool (like OpenCore Legacy Patcher) to upgrade your OS to a supported version, which would allow the use of the official, current OneDrive client.

This is the most critical section. Running OneDrive (or any software) on an unsupported OS exposes you to three major risks:

If your OneDrive auto-updated to a version that crashes on launch, here is how to perform a clean downgrade to the last working version. Usable but deprecated
