A friend of mines has a MacBook with MacOS X 10.5.8 Leopard on it but it doesn't bear a serial number.
We checked "About this Mac".
We checked "System Information".
And we even checked underneath the MacBook where Apple usually engraves the MacBook's serial numbers.
My friend can't view most websites and doesnt have any of the original packaging.
Is there anything else we can do to find out the MacBook's type and serial number?
