I purchased a refurbished iMac "originally released May 2011" from Apple (http://store.apple.com/us/product/FC812LL/A ), hoping it'd still have Snow Leopard on it.
Ended up having Lion on it. My Googling says it originally came with 10.6.6, so it definitely supports Snow Leopard, but I guess in the refurbishing process they upgraded it to 10.7 and now I can't get it to go back.
How can I downgrade an iMac12,1 from Lion to Snow Leopard?

You can do this if you have an older Snow Leopard-compatible Mac.
