“Upgrading your operating system to macOS 10.14 or later will allow Office updates to be delivered for your apps. 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,” Microsoft explains. “As of the November 2020 (build 16.43) update for Microsoft 365 for Mac or Office 2019 for Mac, macOS 10.14 Mojave or later is required to receive updates to Word, Excel, PowerPoint, Outlook and OneNote. Microsoft says that Microsoft 365 for Mac and Office 2019 for Mac would no longer receive updates on an Apple computer unless it runs macOS 10.14 Mojave or a newer version. Needless to say, the change doesn’t come as a big surprise, as dropping support for old OS versions is something that happens on all platforms.

Go through the list looking for your critical programs to make sure they are 64-bit or to see if a 64-bit version is available from the creator of the program before upgrading to Catalina. To make it easier to see the Application Name and whether it’s 64-bit or not, drag the 64-bit header from the far right to the far left so it’s right next to the 'Application Name' column. To do this, click on the Apple icon in the upper left corner, then on 'About This Mac' and then on 'System Report.' When the report opens up, scroll down to the 'Software' section and click on 'Applications.'Īn alphabetical list of applications will appear with various details about each one. If you scroll to the far right, you should see a column that says '64-Bit' and the words 'Yes' or 'No' for each application. For those who are considering an upgrade to Catalina, a good first step is to see what 32-bit programs you are currently running to determine if they are important to you or not.
