How to Access MacBook’s Serial Number

macmacbook promacosserial number

A friend of mines has a MacBook with MacOS X 10.5.8 Leopard on it but it doesn't bear a serial number.

We checked "About this Mac".

We checked "System Information".

And we even checked underneath the MacBook where Apple usually engraves the MacBook's serial numbers.

My friend can't view most websites and doesnt have any of the original packaging.

Is there anything else we can do to find out the MacBook's type and serial number?

Best Answer

If the main thing you're after is the serial number, you can use Terminal to fetch it.

More specifically:

  1. Launch Terminal

  2. Copy and paste the following command:

    ioreg -l | grep IOPlatformSerialNumber

  3. Press return

NOTE: If the above doesn't work then something strange is going on. However, depending on the model of MacBook, you may be able to remove the battery and check around the battery bay to see if the Serial Number and Ethernet ID are printed there.
