We’re excited to announce that OneDrive sync for macOS will now run natively on Apple silicon. This means that OneDrive will take full advantage of the performance improvements of Apple silicon.
We know this has been a long-awaited and highly requested feature, and we’re delighted to make it generally available starting with build 22.022.
22.022.0130 from the App Store still appears Intel only, but this is good news.
