Associate your Apple ID with your user account. Then sign in to the App Store with the same ID.

Right-click or control-click the line and select

from the contextual menu.* A folder may open with a file named "adoption.plist" selected. If it does, move the file to the Trash. You may be prompted for your administrator password. Log out, log back in, and test.

from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
