Mac OS Catalina anybody?

I was looking for a program I want to use, and notice a lot of OS X programs are being sold only as OS Catalina or better (64 bit) and I’m running El Capitan now so I can't use them. With that trend, and all new systems being sold with 64 bit systems, it seems that is the only platform going forward.
I depend heavily on HanDBase and have for decades now so I can’t loose it. I need to know if people are actually running successfully the new 64 bit HanDBase on Catalina. I would like to upgrade my OS, but can’t if HanDBase isn’t there yet. I know Dave updated to the 64 bit version but I have not heard much success from users of this new HanDBase version.
Any success out there? I’m on a MacBook Pro, mid 2012.
