Never used a mac and just got a MacBook pro 2.4ghz core 2 duo given to me for free. Was told it worked great until the prev owner "wiped" the hard drive. I know PCs so figured this should be an easy fix, I was wrong.. Every time I boot I get an OS X Utilities menu (no matter if I press cmd +r or option+cmd+r). Same menu always comes up. I select Reinstall OS X and connect to wifi. Every time it wants to reinstall mavericks and when it tries to download it I get "this item is temporarily unavailable". I saw some posts about making a bootable usb but I do not have access to any other mac and this one does not boot at all. So what's a new mac user to do?? Thanks for any advice folks!!
