have a 13 inch, mid 2009 MacBook Pro. I have 2gb RAM and a 2.26 GHz Intel Core 2 Duo processor. I'm currently running Leopard 10.5.8. I figure it's time for an upgrade and want to move up to Mountain Lion as it looks great and will sync with my iPhone. I know Apple says that Mountain Lion will work with a mid 2009 pro, but how slow will it be with my specs? Is it worth running? I was going to upgrade to 5gb RAM eventually, and thought that this would be a good time to do it, but would it be worth upgrading to ML before I upgrade my RAM in a few weeks time? I'll probably upgrade the RAM mid August, so how bearable do you think it'll be between now and then?? Worth it? As I REALLY want ML.
