Is Big Sur capable of supporting 32-bit applications? I use a 32-bit app as a workhorse for my paperwork. I paid for the stand-alone application years ago. The 64- bit version is now only available on a monthly subscription basis, so I have not upgraded my Mac’s OS so I can keep running the 32-bit application. I am hoping Apple will make an upgrade that will run for 32-and 64-bit apps again.
MacBook Pro 13″, macOS 10.14
Create a small APFS volume and install some 32-bit supporting system like Mojave or El Capitan to it (your Mac has to support that system). Or create a VMware virtual machine (VMware Workstation 12 Player is free for personal use) in Big Sur and install that old macOS to it (it can be set to share a folder with Big Sur). I have both for some old 32-bit apps in Big Sur.

32bit apps are no longer supported as of Catalina 10.15. They won't be coming back.
