While most Office users have nothing to worry about, there are big changes in the next macOS codenamed Catalina.
macOS v10.15 Catalina is out now for Mac computers and represents a major change.
Catalina = 64-bit programs only
For the first time, macOS Catalina will only work with 64-bit programs.
That’s not a problem for most people because Apple and developers have been working towards this for years. All modern Mac applications are 64-bit and have been for some time.
Office for Mac and Catalina
The latest or recent versions of Office for Mac are ready for Catalina (ie 64-bit):
- Office 365 for Mac (fully updated)
- Office 2019 for Mac
Office 2016 for Mac after v15.35 is also OK for Catalina. After v15.35, Office 2016 for Mac is 64-bit only. If you’ve been updating Mac Office 2016 regularly, you’ll be OK.
Office 2011 for Mac will NOT work because it’s only 32-bit. Also support for Office 2011 ended in October 2017 so it’s really past time for a switch to either Office 365 or Office 2019 for Mac.
