Disregard, downloaded MacPass and all is good.
Hello Paul, I get Bad File- "You are opening an old version fromat file (KDB). This app supports only new format (kdbx), please use KeePas v2 to convert between them." I'm not finding a v2 download for Mac.
Mac OS Catalina not compatible for KeepassX so I downloaded KeePassXC and imported my .kdb. Error indicates db file may be corrupt. It worked fine before.
