App Store download progress doesn't go away after successful download Even after I successfully download any apps from App Store, the progress of that download doesn't go away from dock.



How can I fix it? 

The problem is on macOS High Sierra, 10.13.4.
Restart the Dock by executing: killall Dock.
Reset NVRAM.
Reset SMC.


Resetting NVRAM clears the cache which generally causes the issue.
