I've seen plenty of how to's on how to upgrade if you have a working installation of OS-X, however I purchased this macbook used, it needed a hard drive and a keyboard.
So I put a new hard drive in it and installed Ubuntu temporarily.
How do I get the image of the newest OS-X onto a USB thumb drive? I can't access the mac store since I don't own any other Apple products.
Keep in mind I'm using a regular, non-mac external keyboard until my new one shows up.
