Onedrive For Macos 10.13.6 [updated] (Works 100%)

Once upon a time in the digital world, there was a traveler named High Sierra (macOS 10.13.6). For many years, High Sierra

and its companion, the OneDrive Sync App, worked together seamlessly to keep files safe in the cloud.

But as the digital seasons changed, Microsoft announced a new rule: to keep their systems fast and secure, they would only support the three most recent versions of macOS. On September 10, 2021, the official partnership between High Sierra and new versions of OneDrive came to an end. Here is what the journey looks like for High Sierra today: The Blocked Path

If you try to download the latest OneDrive from the Mac App Store today, you will find it requires macOS 13.0 or later. New installations on older systems like 10.13.6 are now blocked. The Hidden Workarounds onedrive for macos 10.13.6

While the official road is closed, seasoned travelers have found secret ways to keep their files moving:

The App Store Time Machine: If you previously "purchased" OneDrive on your Apple ID, you can sometimes go to the Purchases tab in the App Store. Clicking the download icon there may prompt a special message: "Do you want to download the last compatible version?".

The Archive Seekers: Some users look for Version 21.203.1107.0004, which was the final release to support High Sierra. However, Microsoft no longer provides official download links for these legacy versions for security reasons. Once upon a time in the digital world,

The Web Harbor: The most reliable way to stay connected without upgrading your Mac is to use OneDrive for Web. While it doesn't sync automatically to your Finder, it allows you to upload and download files through any modern browser. The Future Horizon

To get back to the full sync experience, the story suggests upgrading your Mac to at least macOS Mojave (10.14) or higher—though macOS 13.0 is now the modern standard for new installs.

OneDrive for macOS 10.13.6

OneDrive for macOS 10.13.6 is Microsoft’s cloud-storage client tailored for older macOS High Sierra systems. It provides file synchronization between a user’s Mac and Microsoft 365/OneDrive cloud storage, enabling access to files across devices, automatic backup, and basic sharing capabilities—while reflecting the limitations and considerations of running on an older OS release.

Option C: The Network Drive workaround

If you have a NAS (Synology, QNAP, or even a Raspberry Pi) on your local network:

Run the modern OneDrive sync client on the NAS.
Share the folder via SMB (Server Message Block).
Mount the SMB share on your macOS 10.13.6 machine.

Result: Your High Sierra Mac sees a local network drive. The NAS handles the cloud sync. This is the most reliable enterprise-grade solution.

High CPU Usage (kernel_task)

Problem: OneDrive’s older sync engine (pre-macOS File Provider API) uses a kernel extension for file watching. On High Sierra, this can conflict with Spotlight indexing. Solution:

Go to System Preferences > Spotlight > Privacy.
Drag your OneDrive folder into the list. This prevents Spotlight from scanning the sync folder while OneDrive writes to it.

Option A: The Browser Interface (The Nuclear Option)

Simply stop using the desktop app. Access onedrive.live.com via Firefox (which still supports High Sierra with an Extended Support Release) or Chrome (last supported version for High Sierra is Chrome 116).

Pros: Always works, zero sync errors.
Cons: No offline access, no drag-drop folder sync.

1. No Security Patches

The last compatible OneDrive client (23.169.0823) has known vulnerabilities that Microsoft has patched in newer versions. For example, CVE-2024-21308 (a privilege escalation flaw) was fixed in v24.022. High Sierra users remain vulnerable.
