Can I upgrade the OS from 9.2.2 to 10.4.6 without doing every single update? I am having a problem finding Mac os x but I do have 10.4.6 I am on an old Imac and I read on the apple webpage that the computer was compatable with the latest operating system but I don't have all of the other ones before 10.4.6 so I guess my questions is can I jump or will it mess everything up?
