Hello, I want to run a clean install of OSX Lion because I hate the fact that the app store installed it on top of OSX Snow Leopard. I know how to perform the clean install but I have one major concern. I have a ton of important documents and programs and such that I do not want to lose. I have a Time Machine backup but will the fresh lion recognize it? Meaning if I select my external HD for the Time machine on the freshly installed lion will it erase the HD to start a new one or will it cross over so I can use it to bring everything back? OR is there a better way to keep all my data? PLEASE HELP! Thank you very much!
