nrnrnr Posted October 23, 2013 Share Posted October 23, 2013 I just installed Mavericks 10.9 on a mid-2013 macbook air. The external keyboard is no longer working from either usb port (external usb mouse does work, however, as does external firewire display). Reset SMC to no effect. Any suggestions appreciated.

nrnrnr Posted October 26, 2013 Author Share Posted October 26, 2013 Problem solved: a different external / usb keyboard attached and underwent initialisation process. The apple keyboard worked after that. Could have saved myself hours. Link to comment Share on other sites More sharing options...
