Hi there! As the title says, I have an MacBook Air (Late 2010 - MC505LL/A*), with preinstalled OSX Lion. Also it shipped with an USB key called "Recovery Key", and afaik, I'm supposed to use this key if I restore/format my Mac The problem is that I can't find the USB key, and I'd like to know if I can do a fresh install of Lion without it. I have an ISO image of Lion (to use with an external reader)... and I've read that there's an Internet process, where I can press CMD + R while booting, to perform a fresh install with a internet downloaded image, but it's not avalaible on all models. Will this work ? I'll try it this weekend, but I'd like to know if anyone has experience in something like this. Thank you all !
