A Note on Downloads for Apple's MacOS


	Apple now marks packages (tarballs and the like) as "contaminated" 
when downloaded from a browser (they want developers distributing software 
from their App Store). But the packages can be safely downloaded with these 
commands from a terminal window without any problem:
