Office High Sierra: Why You Need to Update Your macOS

If you're still using an older version of macOS, you may be wondering what's happening with your Office apps. The truth is that if you don't update your operating system, you won't receive any updates - including security updates.

Starting from the November 2022 update (16.67), macOS Big Sur 11 or later is required to receive updates for Word, Excel, PowerPoint, Outlook, OneNote, and Defender. This means that if you're still using an older version of macOS like High Sierra, you'll no longer receive any updates.

But what happens if you don't update your macOS? Well, your Office apps will still work, but you won't receive any updates including security updates. This is a major concern, as new versions of macOS are released and older versions become unsupported, we highly recommend that you continue to update your macOS to a supported version in order to receive mainstream support such as security updates as well as new features.

If you're unsure about what to do, you can learn more about the latest macOS releases. Note that new installs of Microsoft 365 for Mac also require macOS Big Sur 11 or later.

Upgrading your operating system to macOS Big Sur 11 or later will allow Office updates to be delivered for your apps. So, if you continue with an older version of macOS, your Office apps will still work, but you'll no longer receive any updates including security updates.

If you encounter any issues while using Office, please send us feedback so we can address them. You can do this by selecting the 'Send Feedback' icon in the top-right corner of the app, or by contacting our support team through the 'Help' menu.

For the best experience with the new operating system, make sure that you have installed the latest updates for Word, Excel, PowerPoint, Outlook, and OneNote. Don't miss out on important security updates - update your macOS to a supported version today!
