-6003F error message
Installed the latest updates on my macbook air and was got the flashing folder icon on restarting. Tried cmd-R (at my parents place, can't remember if I've connected to their wireless network before) and I then got 'apple.com/support -6003F' error message. Can't find any reference to this error code when searching apple support or google. Have tried disabling security on router but this makes not difference. Will try again from usual location. Would be grateful for any advice.
MacBook Air (13-inch, Mid 2012)
