Important Update for macOS Users: Why You Need to Upgrade to a Supported Version

If you're still using an older version of macOS, it's essential to know that your Office apps will continue to work, but you'll no longer receive any updates, including security updates. Starting with the November 2022 update (16.67), macOS Big Sur 11 or later is required to receive updates to Word, Excel, PowerPoint, Outlook, OneNote, and Defender.

Why Update Your macOS?

Upgrading your operating system to a supported version ensures that you'll continue to receive mainstream support, including security updates and new features. New major versions of macOS are released regularly, and older versions become unsupported, which means you won't receive any updates if you don't upgrade.

What Happens If You Don't Update Your macOS?

If you choose not to update your macOS to a supported version, your Office apps will still work, but you'll no longer receive any updates, including security updates. This means that you may be vulnerable to security threats and won't have access to new features.

How to Check for Updates and Provide Feedback

To ensure you're receiving the latest updates, select 'Send Feedback' from the Help & Settings tab in OneDrive or 'Contact Support' from the Help menu in Outlook. For Word, Excel, PowerPoint, and OneNote, select the Feedback icon in the top-right corner of the app.

Upgrading your macOS to a supported version is crucial for ensuring you receive mainstream support, including security updates and new features. If you're using an older version of macOS, it's highly recommended that you upgrade to a supported version to continue receiving updates and stay secure.
