I just bought a (2015) macbook air, from some guy. It came with no charger. Was told it was just dead. Got it some power an i find out there is no hard drive. I do NOT know much about macbooks or computers.
I need to know if i buy a harddrive with the OS already on it that is ready to use will i have any problems? Like could this guy have left a password or anything in this computer?
Basicly will a new harddrive make my laptop boot up like a new computer so i can use it?
You say that that there's no hard drive but how do you know?
A 2015 Macbook Air won't have an actual hard drive anyway. From 2010 onwards all Macbook Air models have used solid-state drives. What makes you think that the SSD has been removed (rather than, say, the OS being wiped from it or otherwise being unavailable)?
