Full retail copy of MacOSX Leopard. Official and completely legit.
The only difference between this and the version you might buy in shops is that this is the disc that was 'dropped' into retail Mac desktop and laptop computers on the day that Leopard was launched, to ensure that all the models sold came with the latest version of the OS.
This is not a machine specific grey disc. It is a full version that I no longer have use for. This does not require a serial number.
Disc comes in a protective paper sleeve.
Price includes shipping. Payment by Paypal gift or bank transfer.
