Apple's MacOS Catalina Doesn't Support 32-Bit

A few jobs recently have involved problems with Macbooks, where they have upgraded to MacOS Catalina. Unfortunately, Catalina has removed the support for 32-bit applications. This has caused some of the Apps on client machines to stop running unexpectedly. If you have Apps that you are reliant on and they are 32-bit you may want to think twice about upgrading for the time being. Also, make sure you always do a backup before doing anything.
