I have to execute a command on Mac OS:

```
killall -KILL "Google Chrome"

```

When I execute it in terminal or run a .command file with this command it works.

I tried this all in Java code

```
Runtime.getRuntime().exec("/usr/bin/killall -KILL \"Google Chrome\"");
Runtime.getRuntime().exec("killall -KILL \"Google Chrome\"");
Runtime.getRuntime().exec("/bin/bash -c \"killall -KILL \\\"Google Chrome\\\"\"");
Runtime.getRuntime().exec("bash -c \"killall -KILL \\\"Google Chrome\\\"\"");
Runtime.getRuntime().exec("/usr/bin/killall", new String[]{"-KILL", "Google Chrome"});
Runtime.getRuntime().exec("killall", new String[]{"-KILL", "Google Chrome"});
Runtime.getRuntime().exec("/bin/bash", new String[]{"-c", "killall -KILL \"Google Chrome\""});
Runtime.getRuntime().exec("bash", new String[]{"-c", "killall -KILL \"Google Chrome\""});

```

And it doesn't work. 

What may be the problem?
