I got a MBP 13" (late December 2011). I'm not feeling the love for Lion, want to downgrade to Snow Leopard. I know people say installing SL isn't possible on late 2011 models, but I know of a few instances where people used the grey non-retail 10.6.7 DVD that came with early/mid-2011 MBPs for their late 2011 (came with Lion preinstalled) MBPs, and after updating to 10.6.8, everything worked like a charm. The problems/questions I have are: a) Obviously, as this laptop came with Lion, I don't have the SL DVD handy. Short of downloading it illegally, which is something I don't want to do, is there any way I can request this from Apple? Think I'll get pushback? I'm trying to find a friend who has the hard-to-find 10.6.7 DVD, but that may be hard to impossible. b) The instances mentioned above were for MBPs from August-October 2011. I'm not sure if the 10.6.7 DVD would even support a December 2011 MBP, because it's possible Apple added some kind of hard block for SL in those laptops. I'm probably wrong, but it doesn't hurt to ask. c) Would this void my AppleCare? Thanks!
