Next month, on September 10, 2021, OneDrive sync client will no longer update or be supported on macOS Sierra 10.12 and macOS High Sierra 10.13.
The OneDrive team is committed to bringing the best and most secure experience possible to your devices. Both macOS Sierra 10.12 and macOS High Sierra 10.13 have been out of Apple’s mainline support since September 2019 and November 2020, respectively, and the time has come to end updates and support for the OneDrive Desktop application (sync client). The team will focus their resources on new technologies and supported operating systems. Plus, moving forward, only the three most recent versions of macOS will be supported. This means if a new major version of macOS is released, the new version and the previous two versions will be supported.
Existing OneDrive sync client installations on unsupported operating systems will continue to run but they will stop updating, functionality will no longer be tested, and any issues or bugs found will not be investigated or fixed. It is recommended for a smooth transition to upgrade machines to macOS Mojave 10.14 or above, or for the best user experience and longest support lifestyle, upgrade to macOS Big Sur 11.0 or above.
