How to fix "Killed: 9" error in mac os?

Question

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?

If you replace a signed macOS binary by using cp instead of mv then macOS caches the signature, doesn't like the look of it because the file changed and kills your process when you try and start the new binary. Clearly, this is a bug in macOS. We had to update our install scripts to copy the file a different way.

I was able to fix it after running this command found in this homebrew github discussion:
brew reinstall pcre2 gettext

Hope this helps

in my case there was some process called syspolicy or something like that, once i killed that process, running my command python3 no longer returned killed 9.

Close the terminal window you're getting those errors in and open a new one.

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