My Question or Issue

Hi, I'm having difficulties installing Spotify on my Mac. I've downloaded the installer, but it won't open when I double-click on it. I've launched the installer through the terminal and get a Killed: 9 error message.


I've also managed to download the .dmg file from and I get the same Killed: 9 error on launch.


Is anyone able to help?


Thank you!

Hey @allan_str, welcome to the Community.

Hope you're doing great!


Could you try the following:

  1. Download UPX. If you have Homebrew run this command in Termnial: brew install upx
  2. Decompress the binary using the follow command: upx -d /path/to/

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


Let me know how that goes 🙂
