I try to kill a buggy application without success.

I tried the Force Quit… feature in the Apple menu but it doesn't work.

In order to find the PID I tried the following command from the Terminal but it doesn't match anything:

ps aux | grep -i MyApplicationName

The only way to effectively kill it is to restart the system. Sometimes I need to force restart because the buggy application is preventing the system to restart.

I'm running Mac OS X 10.9.5 on a Retina 13' MacBook (late 2013)

    Could you tell me which system version do you have?

  • I had this issue on 10.9. After I have had moved to 10.10, issue has gone.

  • I'm not confident enough in 10.10 for now: I hear so much bad thing about it like if it was the apple "vista" :-) Feb 20, 2015 at 11:21
  • I'm quit sure this is a bug from the OS. Feb 20, 2015 at 11:22
