How to find your Serial Number
The serial number is available in several locations and may use the prefix 'SN':

- On the outside of the packaging. Usually on a white label along with other information, such as the product code.
- In the About This Mac window. Clicking twice on 'Version' will display your serial number.
- Using System Profiler
- On the hardware itself. The location depends on the type of mac you have, but often it is located inside an access panel, such as a PowerMac G5 side door, inside a PowerBook battery compartment or underneath an iBook's keyboard.
