Deleted application won't disappear from dock (not responding)

Have you tried restoring the Dock to its default state? If not, consider doing the following:

Type the following in the Terminal:

defaults delete com.apple.dock; killall Dock

Then hit the "return" key.

You may possibly have to reboot after doing that. Then you will have to re-add whatever apps and such you had in there before.

Please let me know if this is helpful, or if it resolves your issue. Thanks! :)

You can remove an icon out of the dock by clicking on it and drag it upwards until it disappears. That said, I’m not sure if you have properly deleted the app.

I think you should mention here which app you removed and people on this forum can tell you how to check if all components are cleaned up

You are most welcome, my friend. I am glad it was helpful to you and that you were able to get things back in order. :)

I suggest that you keep a backup copy of my instructions for future reference, in case it happens again.

Try resetting the dock with Terminal :

defaults delete com.apple.dock; killall Dock

Caution: This will make the dock like a new system.
