What's the 'unique device identifier' (UDID) of a non-iOS device like a Macbook Pro running Mac OS X?

Solution 1:

Go to  > About this computer > System Report... > And there you will find Hardware UUID

Solution 2:

The Mac equivalent of a UDID is a Serial Number. It can be found by click "About This Mac" in the  menu, and clicking twice on the version number.
