I've just bought a MacBook Pro The system won't recognise the serial number which I've copied very carefully several times from the underside of the computer
The helpline is closed Any ideas? I don't know what the operating system is - how do I find that out?

What are you trying to do?
The operating system can be found by going to the Apple menu and selecting "About this Mac"
Under "Mac OS X" should be the Version 10.6.x, clicking Software Update will update the operating system via the internet.
