Reinstall Mavericks using Recovery
I have a 2010 iMac I bought from original owner. It came with Mavericks installed. The iMac began to run very slowly, I installed the original os it came with from the original disc, Snow Leopard. I retained the previous Recovery HD partition. Still running slow. I bought a new external hard drive that I will make bootable, but I want to reinstall Mavericks on the internal hard drive first. I'm using the Recovery HD to reinstall, it gives no option and goes straight to os x Mavericks install. After I log in with my apple id, a window pops up saying "This item is temporarily unavailable. Try again later." I've been trying hourly and daily for about a week and always get this message.
Does any one have a solution for this? Thanks
iMac, Mac OS 8.6 or Earlier
