Deleting apps
I wonder if anyone can help. I am trying to delete an app off a MacBook Air. I have gone to Launchpad and then held down on the app but it (not any of the apps) doesn’t shake and no cross appears. I then went to Finder and clicked on Application folder but it is blank. Firstly why can’t I delete the app and secondly why is the application folder bland when I do have apps? The apps open no problem when I click on them. I would be grateful for any help.
MacBook Air 13", macOS 10.14
