I have a MacBook Pro w operating system Mac OSX Version 10.5.8. Can I update the operating system to something newer or do I need to buy a new computer? Thanks in advance for your help.

MacBook Pro, Mac OS X (10.5.8)

    If the computer has at least 1GB of RAM, it can be upgraded to Mac OS X 10.6.3 and then 10.6.8. MacBook Pros with a Core 2 Duo(not Core Duo) or better CPU can be upgraded further, but going through Mac OS X 10.6.8 is needed to do so.


    You don't need to buy a new computer, as any MacBook Pro model released in the last 5 years with sufficient RAM can run 10.8.3.
