I'm typically slow on the update to newer Mac Os's, as I wish to wait until most programs will work with the newer OS. Wonder if it's time to update to Catalina?

If you go to the Apple menu > About This Mac > System Report > Applications, it will list every app in your system. There's a column that says "64-bit (Intel)" which will tell you whether an app is 32-bit or 64-bit. If you upgrade to Catalina, any app that say No in that column will not work.

That's part of the reason why I'm still on High Sierra for my music machine.
