Hey everyone im new to mac. I bought a new MB UNIbody. I have been learning little by little day by day. I wanted to see if i could install Ubuntu v8.10 on a partition and go dual boot with it. I only used a 5 gb partition. Now when i start up t goes right to Ubuntu. I have been hitting the C button to change back to OSX. My Question is, Did I screw up and not install it right? Can I go back to default settings? Is it just a button i am missing to go back to OSX? I would love to go back to OSX. I just wanted it as a dual boot.
