I get this error building in macOS Catalina for any project I created before, and even new ones.
E: Fatal Error: /Users/xxx/Applications/Fire.app/Contents/Resources/Mono/lib/../lib/libmono-native.dylib assembly:<unknown assembly> type:<unknown type> member:(null)
I used another Macbook with macOS Mojave to install Fire and saw the 32-bit warning on libmono. I installed an external mono library but it doesn’t use it for builds. Is there a workaround for the meantime to use an external mono library to run builds?
