How do I update to Catalina now that Big Sur is out?

It looks like they will still work for those on Mojave or newer that have the updated version of the MAS. For those on the older macOS versions gibMacOS is the best option to download the installers.

I see. So what you mean is that Apple "updated" the Mac App Store and High Sierra or earlier can no longer download or update apps. Correct?

Well I finally got Catalina installed on my second drive. Used newest Multi Beast for Catalina. All went well but no audio out from the mother board only coming through the one monitor hooked up with HDMI. Any ideas how to get audio working on mother board?
