Force quit OS X app

Which is the best way to force quit an os x or daemon process if I know the app/daemon name (the name that appears in activity monitor)?

I am using objective C for coding.

Solution

  • You may use Applescript to do that:

    //tell Application to quit
NSAppleScript* restartApp = [[NSAppleScript alloc] initWithSource:@"tell application \"ApplicationName\" to quit"];
[restartApp executeAndReturnError:nil];

    If the app is not responding you may try

    // define command
NSString* appName = @"Finder";
NSString* killCommand = [@"/usr/bin/killall " stringByAppendingString:appName];

// execute shell command
NSTask *task = [[NSTask alloc] init];
[task setLaunchPath:@"/bin/bash"];
[task setArguments:@[ @"-c", killCommand]];
[task launch];

    which kills the app.

    Good luck
