Hello. I was wondering if anyone has experience running or at least using OS X Lion on a MacBook 3,1 with a 2.2 GHz Core 2 Duo and 4 gigs of RAM or a similar system. I'm thinking about moving up from Snow Leopard 10.6.8 but don't want to do it if it's going to bog the computer down. I know the machine satisfies the basic system requirements, but I want it to be usable in a non-frustrating way. Thanks.
