OneDrive for macOS 10.13.6: Comprehensive Compatibility Guide
Microsoft aligns its OneDrive support with Apple’s "n-3" policy. This means they only support the three most recent versions of macOS. Because High Sierra is now several generations behind, the modern OneDrive app will not install or sign in on this version. ⚠️ The Compatibility Reality Official Support: Ended in September 2021.
Current App Store Version: Requires macOS 11.0 (Big Sur) or later.
Security Risks: Older versions lack the latest encryption and bug fixes. 🛠 Best Workarounds for High Sierra Users 1. Use OneDrive for Web
The most reliable way to access files on macOS 10.13.6 is through a browser. Open Safari, Chrome, or Firefox. Go to live.com. Pros: Full access to all files; no installation needed.

This is a challenging request because Microsoft OneDrive no longer supports macOS 10.13.6 (High Sierra). Microsoft officially dropped support for High Sierra in March 2022.
However, I can put together a technical white paper covering the historical compatibility, the final working version, workarounds for legacy systems, and security risks.
OneDrive servers constantly rotate their security certificates. While version 22.218 has built-in root certificates from 2022, those expire. Eventually, the server will present a certificate signed by a root that your High Sierra no longer trusts. When this happens, sync will fail with a "SSL/TLS error."
Despite the warnings, you can still get a functional version running if you have the right installer. Microsoft maintains an archive of older builds, though they hide them well.
Microsoft employs a "minimum version requirement" handshake. Starting in 2023, the OneDrive servers began rejecting connections from clients older than 22.218. If you are on 10.13.6 and try to sign in, you will likely see:
"You’re syncing on an older version of macOS. To continue using OneDrive, upgrade to macOS 10.14 or later."
The bottom line: You cannot use the latest OneDrive build, and the older build may have its sync functionality restricted or blocked entirely.

Understanding the limitations is crucial before relying on OneDrive for critical work.
