How to find your serial number in software
You can find your Mac's serial number in Apple System Profiler: Select the Apple Menu > About This Mac, then (depending on the version of OSX you are running) click the System Report button or the More Info button. This brings up System Profiler, and on the Hardware Overview that is displayed by default you should see your serial number, and be able to copy/paste it. The procedure does vary slightly between different versions of OSX.
