how do i buy and install mac os 10.7 to a cleaned mac

A local school is selling some used macs, but they're being sold without OS or any software. Software I have, but how can I buy and install os 10.7?

  • OSX 10.7 (Lion) can only be installed from the Mac App store which is available in Snow Leopard. Therefore you would need to purchase Snow Leopard (OSX 10.6) on a disc, install it and update to the latest version (10.6.8) then you can download 10.7 from the Mac App store.
