How To Do A Factory Reset
Selection A should be used on computers that came with Lion or later when factory new. These models had no disks included when new. Selection B is for Macs that came originally with Snow Leopard or earlier. These models shipped with Software Restore disks when new.
A. Factory reset of your Mac - Apple Support
B. Factory Reset Your Pre-Lion Mac
