have old digital stuff? bought this on auction by mistake some years ago. do not know anything about (not a mac person) seems to me problem with HDD or OS do not boot. the excellent condition seems to me it was a long time in storage. can trade to some photo gear(old digital cameras, optics, etc. ) or android tablets can meet in Brooklyn public Wi-Fi place so you can check before buy/trade. open to any propositions except donation)))
