After Upgrading to osx 10.11.5 Some Apps won't close properly. An unfunctional App Icon(with the black dot) stays in the Dock. I can start the App again, which leads in an additional Icon. When i run the command 'killall Dock' the multiple Dead Icons get reduced to one. It seems that mostly opengl using Apps are kept in the Dock after closing.

• FOr example, if iTunes won't quit and its PID is 1234, type: kill 1234 to force quit. Note: The PID of an app will will change each time the app is launched. Way 3: Uninstall Apps That Won't Force Quit. If you can't make a third-party software to close by the above methods, then it is very likely that there is a problem with this software.
• On a Mac, press 'Command-Option-Esc' on any screen or switch to the Finder, select the Apple icon at the top left and choose 'Force Quit.' From there, highlight the name of an app and click 'Force.

These days most apps on your Mac are easy to understand. You can even use Launchpad to manage — and delete — them like iPad apps. Sometimes, though, they still don't work the way iOS apps do. For example, if you want to delete an app, but it doesn't have an X when you trigger jiggle mode, or when you try to delete it old-school style in Finder, you get a message that reads, 'The item '[app name]' can't be moved to the trash because it's open.'

It happens because the app is still processing in the background and, for one reason or another, that background process has failed to properly shut down. Cue all the cursing! Or, better yet, read on and I'll show you how to shut it down and get it gone for good!

Note: I used the Rocket app as an example in my pictures, but only because I was removing an earlier version. I love Rocket and would never delete it (it emojifies your Mac!).

How to close an app that you thought was already closed or can't figure out how to close on your Mac

1. Click on the Finder icon in your app dock.

2. Select Applications from the Favorites list.

3. Scroll down and double-click on Utilities.

4. Double-click on Activity Monitor.

   You can also just type 'Activity Monitor' into Spotlight.

5. Type the name of the app you are looking for into the Search bar.
6. Select the app.
7. Click on the X in the upper left corner of the window.
8. Click Quit to confirm that you want to quit the process.

The app is now closed and you can delete it from your Mac.
