The OneDrive engineering team is committed to bringing you the best, most secure, end user experience possible.  To support that commitment, the OneDrive Desktop application (sync client) will look to phase out support for Mac OS X Yosemite 10.10 and 10.11.  These changes will go into effect February 1st, 2019.

Note: Mac OS X Yosemite 10.10 has been out of mainline support since August 2017.

How does this affect me?

  • Existing OneDrive sync client installations on unsupported operating systems will stop updating. These clients will continue to run, but 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 do I need to do to prepare for this change?

To ensure a smooth transition we recommend that you upgrade machines to Mac OS X 10.12 or above before February 1st, 2019. We do recommend updating to macOS Mojave 10.14 for the best experience.
