Sometimes, files downloaded from deployment.mediabeacon.com files seem to not be present upon download. This results in "unexpandable" .ZIPs.
What is going on is some files are hidden, and moreover are incorrectly seen as aliases.
How to fix:
In macOS Terminal
ls -alfO // this will show hidden chflags "nohidden" filename //removes hidden flag from a file chflags -Rv "nohidden" foldername //removes hidden flag from a file
SetFile -a av filename
