Hey guys. So here's the deal: I bought my MacBook Pro with Lion. It's a 2012 rMBP. Apple had a thing going after the release of Mountain Lion that anyone who had bought a Mac recently would get the upgrade to ML for free. So I submitted my serial number and DID get it free. I'm running it now. Now, with Mavericks on the horizon, I really want to just format and do a fresh install of ML so that the upgrade to Mavericks, but I can't seem to figure out how to get the ML ISO for my machine, and it's not in my list of App Store purchases. In fact, when I search for it it in the App Store, it show's up with a price. So what do I do now?
