How to mass remove known Wi-Fi Preferred Networks in OS X?
In my list of Wi-Fi Preferred Networks I'm able to remove them 1 by 1, but that takes forever. Is there any way to select all the Network Names I want to remove and delete them at the same time?
You can multi-select & delete from
System Prefs > Network > WiFI > Advanced…
Shift ⇧ or Cmd ⌘ Click to select multiples, then hit the — button underneath.
Note that this will also clear the same settings from any linked iDevice.
