If you want to fix the “Home” and “End” buttons, here is a quick tip to get them working again the way they should.

  1. Open a terminal. You can access it from the Launchpad.
  2. Type the following commands (and press Enter after each line): What the above commands do is create a new “KeyBindings” folder in the “Library” folder and add a new “DefaultKeyBinding.dict” file.
  3. In the text editor that opens, copy and paste the following commands to it: Save (using shortcut “Ctrl + o”) and exit (“Ctrl + x”) the file.
  4. Restart your Mac. The “Home” and “End” should be working now, and you can use it in conjunction with the “Shift” and “Ctrl” modifier buttons.
