I'm currently installing a new SSD in my old MacBook Pro (v 15,1). I created a bootable installer for El Capitan following Apple's guide.
How did my old MacBook Pro automatically connect to my password protected wifi, while booting from a thumbdrive, with an unformatted HD, and without my entering the password?
It connected to the Wifi network that it normally does, but, again, the old drive was not installed, nor was it connected to anything other than a thumbdrive.
Where was the password saved, if not on the old HD? or How'd it connect without my entering the wifi password? Did the bootable thumbdrive copy the wifi information?
