Known issues

Important

MSB4226: The imported project "/Library/Frameworks/Mono.framework/Versions/6.12.0/lib/mono/xbuild/Xamarin/Mac/Xamarin.Mac.CSharp.targets" was not found.

The workaround is to manually remove /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Mac:

sudo rm -Rf /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Mac

and then reinstall the Xamarin.Mac pkg you want to install (there's no need to remove/reinstall Mono).
