As of the Microsoft 365 for Mac, November 2020 update, macOS 10.14 Mojave or later is required to receive updates to Word, Excel, PowerPoint, Outlook, and OneNote. If you continue with an older version of macOS, your Office apps will continue to work but you will no longer receive any updates including security updates.

If your organisation is not using macOS then you can disregard this change, as Microsoft 365 for Windows is unaffected by this change.

Key Points:

  • Major: Retirement
  • Timing: November 10, 2020
  • Action: Review and assess impact

How does this affect me?

As part of the upcoming November 2020 update, existing Microsoft 365 for Mac users on macOS 10.13 will not be offered any further updates. Upgrading the operating system to macOS 10.14 or later will allow app updates to proceed.

Additionally, new installs of Microsoft 365 for Mac will also require macOS 10.14 or later.

What do I need to do to prepare for this change?

To continue receiving the most up-to-date Microsoft 365 features on Mac, make sure all users are running one of the three most recent versions of macOS. Learn more about Microsoft 365 and macOS supportability see the Additional Information.
