I have the 2010 MBP and would like to put it back to factory so that I can sell the MPB. I upgraded to Lion OSX and now when I put the disk in to do a restore it tells me I can't do a restore due to the version I currently have. I did a search (google) on factory reset but I can't seem to find anything. Anyone know of a site where it'll give me step by step instructions on how to do this with the current version I have. Thank you.
