Need help to Delete OS X from Application Menu
I am running OS X 10.10.5 on a Mac Mini. In my Applications folder in Finder, there is an application listed "OS X Mavericks", Date: Jan. 24, 1984 12:00AM, Kind: Document. There is a progress bar in the "Size" column showing partial completion of something. When I try to move this item to Trash, I receive a message "Some of the items you are moving are in use by other applications. Moving the items can cause problems ....." It seems that this should not be needed ... can it be deleted ? If so, what is the right way ? (I have found other posts that suggest deleting it from the Launchpad, but I don't see any "OS X Mavericks" icons in Launchpad).
Mac mini, OS X Yosemite (10.10.5)
