Macintosh will not reinstall.
I followed all the steps for the reinstall for Macintosh HD, I then sign into my Apple account but it says "This item is unavailable try again later." I waited an hour and the same thing popped up. So I waited two weeks and just tried to reinstall again, but it said the same thing. Is this fixable if so what can I do? Or should I just get another computer?
iMac, OS X Yosemite (10.10)
