My sister in law forgot her password to her macbook air after not using it for over a year. GOAL = To get in and recover old photos etc -it has no bootable usb with it (it was an early model, i think before 2012) -i have the boot disc it came with -i have tried to do the command + r and command + s tricks but they don't work unless its lion or later -i think this may only be running snow leopard -my boss told me if i have the boot disc i can put it in my macbook pro and somehow boot from that disc over wifi to get in and change the password -does anyone have a clue what im talking about? -if so, can you help??
