Fully loaded Apple Mac - 13". I am an educator who used many programs. Mac Store cleaned the drive and kept as much software application as possible. Old, but trusted. This computer system has two battery packs, one is the initial and one was bought (never utilized) as a back up in 2009. You can have the backpack too! Cost NEGOTIABLE. Pictures reveal details. Minor hair line cracks as anticipated for this design. Great to GREAT condition!
