I've upgraded my OS to Sierra recently, in El Capitan I had some apps and they were working perfectly, but in Sierra they show me:

Killed: 9

I even execute them via sudo but they won't work.

Any idea?

  1. Download UPX. For example, using Homebrew, run brew install upx.

  2. Decompress the binary:

    upx -d /path/to/App.app/MacOS/App

Also see “This UPX compressed binary contains an invalid Mach-O header and cannot be loaded.”
