Hello everyone, I just got my MacBook pro of eBay and I deleted everything (erased HDD without thinking). So it says I need to install a new Lion OS, which I havnt purchased yet. I messaged the buyer asking if there's anything I could do and he said he will call apple to try to get me a download but I don't think that's going to happen. So what I'm thinking is buying Lion on my brothers MacBook using my Apple ID and then logging onto my MacBook and installing it. Will this work? Just making sure so I don't waste my money. Thanks in advanced everybody.
