Can I use the snow leopard install discs that came with a 2011 Macbook Pro to install SL on a 2010 macbook pro? Do the discs distinguish between years? Do they distinguish between the 13", 15", and 17" as well? So far I did a hard drive swap and put my 2011 macbook pro 13" (original) into a 2010 15" MBP. it worked plug and play but I'm not trusting it so I want to do a clean install. Only problem is, I only have access to the 2011 SL recovery discs, I believe they are 10.6.8 or 10.6.6. Would these work on my 2010 15"? Trust me I did a search but when you start typing 2010 and 2011 and macbook pro, there are hardly any relevant searches.
