Downloads folder is "in process"
This type of things happen when you try to download something from chrome, and close it before finish downloading. If it so, you can try the following steps.


Went to Chrome -> Downloads and clicked Clear all
Restart Chrome
Removed the Download folder from the dock (by dragging it from dock to desktop) and dropped it back on there from your Macintosh
Check your app store, Is there any pending download available or not. If so take care of it.
Restart you machine.


Hope it will help you.
