I am new to a MacBook, I just purchased a used Macbook with version 10.5.8 and I need to upgrade so when I get at least a total 4gb of Ram I can get Mountain Lion on this system. I need to know if possible what the next OS is so I can get the upgrade. Can someone tell me so I can see where to go to from here. Any help is appreciated. If someone has a contact number thta would help too.

MacBook, Mac OS X (10.5.8)
