Apple Catalina Update? Do your homework first.

Apple released the newest update to their macOS, Catalina, on October 7th. MacOS 10.14 Mojave, the version of the Mac operating system before the new macOS Catalina, is the last version that supports 32-bit software. With Catalina, only 64-bit software will be supported. This is a major update from Apple and one that should not be applied until you have done your due diligence to ensure your system is ready.


St. Claire Software has a terrific app called Go64 (free, donations accepted) that scans the software on your Mac and tells you whether the each app is 64-bit or not. Go64 is fast and it also provides web links to the app developer's website, so you can go see if the developer has an update.


We highly recommend that you confirm that all of your apps are able to run in the new OS. 


Also, you will need to make sure that any hardware you are using with your Mac has current drivers that supports Catalina. If you have a scanner, input tablet, printer, or other peripheral please check for updates through the vendor to support Catalina. 


Further details about this update can be found in this article.
