Back in June, Microsoft rolled out someperformance improvements to OneDrive Insiders on macOS. This update offered significantly faster sync, optimized CPU usage, a smaller memory footprint, and better energy efficiency. However, at that time, the company did not specify the schedule for general availability. It has finally shared those details now.
In Message Center advisoryMC1458483, Microsoft has noted that it is rolling out a new Native Sync Engine for OneDrive on macOS, which should improve the overall sync speed, reliability, responsiveness, and resource usage. This modernized experience will also result in synced content being more readily accessible in macOS Finder.
The full list of improvements in tow include:
Microsoft says that customers will be automatically upgraded to this new Sync Engine through a OneDrive sync app update. The update itself will complete seamlessly in the background and won't interrupt your workflows. Online-only files and Files On-Demand remain unaffected, but organizations which sync SharePoint libraries will now see them as separate locations in the Finder sidebar instead of being grouped under a single organization entry.
No admin action is required, and updates to helpdesk and documentation are optional, and purely dependent upon organizational preferences. The new Native Sync Engine will begin rolling out later this month and will be rolled out fully by November 2026. Microsoft has asked customers to open OneDrive Settings and review the version shown on the About tab. If it shows an alphabetic suffix, you have been successfully migrated to the new, more performant engine.
