OneDrive gives Macs a million things to keep in sync

Microsoft is increasing the number of items supported for syncing on macOS using OneDrive to one million, aligning with the same limit on Windows. This enhancement is part of a suite of new features, including Copilot capabilities, improved sharing controls, and an admin command-line tool. The macOS preview of these updates is set to launch in the Insiders channel this month, with a general release expected in June 2027.

To qualify, devices must meet certain hardware and configuration standards; otherwise, users will still be limited to syncing 300,000 items. Microsoft's intention is to enable organizations with extensive OneDrive and SharePoint libraries to synchronize more content seamlessly across devices. However, performance may lag for a large volume of read-only files or accounts under legal hold.

Microsoft remains committed to refining the performance and reliability for these scenarios. The integration of OneDrive with AI is expanding, as seen in the latest update. The Copilot feature can now analyze multiple files simultaneously, organizing folders, and saving workflows as personal skills in a Markdown file. The assistant is further aided by a Prompt Gallery, allowing users to save their preferred ideas without having to generate them anew.

A notable addition is the "Hero Links" feature, which aims to streamline the proliferation of links to files and folders in OneDrive. This feature offers a single link per file and folder, with the flexibility to adjust permissions without changing the URL. Nonetheless, automatic expiration controls are still pending. To manage sync settings and troubleshoot issues, Microsoft has introduced a OneDrive Sync command-line tool in private preview.

This tool provides administrators with valuable insights into account details, configuration, policies, and sync status. It can comprehensively analyze issues, from individual PC backup problems to widespread organization-wide concerns. Additionally, the tool facilitates integration with AI agents.
