Remove stuck Launchpad progress bar from the Dock on macOS
I’m one of those guys who actually keeps the Launchpad icon in the dock on macOS. I have it there to see the progress of installations of apps and updates from the App Store.
And it seems that not many people does this, for every so often the progress bar hangs. That is, it is there, empty, never going away. I’ve reported this to Apple through their Bug Reporter, but the problem has persisted through many versions of macOS.
To fix this, just remove the Launchpad icon from the Dock and add it back from Applications folder.
