MacBook Pro that runs Snow Leopard I want a MacBook Pro that runs Snow Leopard.  I think I need an early 2011 MacBook Pro to be able to run Snow Leopard. Where can I get a new or refurbished early 2011 MacBook Pro.  I don't think a later model will allow Snow Leopard to be installed.
Apple lists all software versions that run on models here:


Mac OS X versions (builds) for computers - http://support.apple.com/kb/HT1159


So you could focus on models that shipped with Snow Leopard and perhaps look at even older models that meet the minimum system requirements for Snow Leopard.
