Apple have released Catalina there latest operating system today , but anyone who is running a mac computer would have been receiving notifications that software that is 32 bit will not work on Catalina.
So how do you know what you may lose in software when you install it.
Click the Apple icon at the top-left of your screen and select About This Mac. Now click on System Report… and once that has loaded click on Applications from the left-hand column. One of the columns will have the heading 64-Bit (Intel) and if you find any that are marked as No then those won’t be supported under Catalina.
You can then go to the developer of the app ( or the website ) and look for an updated version of the app.
