From September 10th 2021, you will not be able to sync OneDrive or SharePoint files on pre 2012 Mac's or newer Mac's still running on High Sierra or earlier.
If your organization is not using macOS you can safely disregard this message.
According to Microsoft they are ending support for the SharePoint / OneDrive Desktop application (sync client) on macOS Sierra 10.12 and macOS High Sierra 10.13 from September 10th 2021.
Although the sync may intially appear to work, further security updates of the macOS will more than likely cause the sync to stop.
How this affects your organization:
How users will be impacted after this change has rolled out:
- Existing OneDrive sync client installations on unsupported operating systems will stop updating. These clients will continue to run, but their functionality will no longer be tested. It is not advised to continue to run on these unsupported operating systems.
- New installations on unsupported operating systems will be blocked.
- Bugs and issues found on or specific to unsupported operating systems will no longer be investigated or fixed.
What you need to do to prepare:
To ensure a smooth transition we recommend that you upgrade machines accordingly. We recommend you upgrade to macOS Mojave 10.14 or above. For the best user experience and longest support lifecycle, we recommend upgrading to macOS Big Sur 11.0 or above
If your Mac is a pre-2012 model and you wish to keep syncing OneDrive and SharePoint files, you now have no option but to trade up to a new Mac
