Hello all, Back in July, I picked up a 2010 MacBook Air that had some water damage. Price wasn't too bad (could have made back my money selling it "as-is water-damaged" on eBay pretty easily) and I'd never taken one of these bad-boys apart. So it was more a learning experience than trying to get a working computer out of it. Long story short: after a new top case and an extensive cleaning, the computer boots up. It's not 100%, the battery's dead (ordered one off eBay), there seem to be some screen blotches on the lower left corner on boot (but in OSX it looks fine oddly enough), there's a five second delay from when I press the power button and hear the chime and I can't seem to be able to boot the Apple Diagnostics software (or its equivalent) by pressing D on boot. Currently it's running Mountain Lion which is fine, but I'd rather put Snow Leopard back on it (I believe the 2010s shipped with SL) to be compatible with some of my software. Problem is, I don't have the USB key that came with the 2010s and has the system restore. I tried booting off my homemade Snow Leopard USB key, which I've used on other Macs, but this one kernel panics with the "You need to restart your computer" message in five languages. The easiest solution seems to be to bite the bullet, buy a copy of Mountain Lion off the app store and do a restore that way (which seems to work). But if I'm going to buy an OS, I might as well get Mavericks and keep this as a test computer. I really just want to wipe the previous owner's data. Is there another way to get SL back on this thing? Thanks so much!
