Okay, my daughter has an old (obviously) white plastic MacBook, that she long abandoned. It is currently running Snow Leopard. I have a job I need to use this laptop for (very short term project). What I need is not very intensive and really all I need is a web browser. I plan on reinstalling the OS before using it. Is there any hope I can upgrade to a newer version of OS X or am I just stuck with Snow Leopard?
