Does anyone knows a way to preconfigure a WPA2 WiFi network on Mac OS X (Yosemite)?
I'm preparing an iMac for a friend and would like to setup his home WiFi while currently far away from the network.
I know all the WiFi parameters (SSID, security, key) but can't manage to validate the manual setup through the AirPort wizard. I also tried to manually add the entry in Keychains, but can't manage to add the confirmation exceptions on "airportd" and "AirPort" binaries in the ACL part.
Thus, I can't setup transparently and remotely the WiFi connection.
