Heads up: macOS 10.15 requires notarized apps

[Jacob Carlborg]

Any applications, this includes command line applications, will require 
to be notarized on the latest version of macOS, Catalina (10.15), which 
is available as a public beta.

This means that by default DMD and related applications won't run. It's 
possible to go into System Preference and launch the application anyway, 
but that's a pretty poor user experience.

I've created an issue for this [1] and directly contacted a couple of 
core members.
