Where is the built-in display .icns, or .tiff in El Cap located? It's showing a Mac Pro, instead of a laptop icon in the displays tab of, "About This Mac" and the display pane in System Prefs. This probably happened from cloning from the MP to the MBP. I've looked in a bunch of common places where .icns, .tiff and .plist files are for the system and user, but I can't find it. Appreciate any help.
