! Before you upgrade to Catalina:


Please look at these Apple Support document. Specifically check that your Macintosh is on the list of compatible computers and familiarize yourself with the limitations of 32-bit applications and Catalina.

How to upgrade to macOS Catalina – Apple Support

Learn about 32-bit app compatibility – Apple Support 


Be aware that any 32-bit apps that you are currently using will be incompatible with Catalina

This includes older versions of MS Office applications and many others. All current Apple software is Catalina-ready, and updates for some older Apple titles are available for download in the Mac App Store.


You can check which of your current apps are 32-bit by clicking Apple menu >System Preferences > About This Mac > System Report. Then scroll down the list on the left to <Software> and click <Applications> (you may have to click the triangle next to Software). It may take a moment, but shortly your Mac will display a list of the apps installed on your computer. You can then click the column labeled 64-Bit (Intel) and sort them by Yes/No.


Any apps that are listed as No in the 64-bit column will not work under Catalina.


This 32-bit detail has tripped up many users who have upgraded to Catalina and then find their software is broken.


Optionally, to check for 32-bit apps, you can use the free app Go64. – it’s a compatibility scanner from St. Claire Software.
