My Macbook air is showing a black screen except for beachball mouse after partitioning
i partitioned my mac to "mac OS extended Journaled" about an hour and a half ago. almost straight after i started it froze but the mouse still moves. then i accidentally shut the lid. it now has a black screen and the "spinning beach ball".
i cannot find the serial no.
Edit: i have just found the box for the mac and am going to open a chat
