Serial Number: Apple
The serial number for Apple computers is printed on the underside of the device in very tiny lettering. Thankfully, there is a way to obtain the number from within the OSX operating system.
- From the desktop, click on the apple symbol, in the top-left of the screen, and select About This Mac.
- In the window that appears, click on More Info...
- In the System Properties window that appears, the serial number appears about half-way down.
