I recently needed support for my 2012 MacBook Pro, and in order to set up an appointment with Apple’s support engineers at the Apple Store, I needed to supply my Mac’s serial number. I had no clue where to find it. Can you help?
Whenever you need to communicate with Apple’s support technicians, they’re going to need to know your serial number, so they can confirm your support availability, and so they can find out more about your computer. (Given a Mac’s serial number, Apple can determine the original configuration of the computer, and can better provide support for you.) Without that serial number, you’re not going to get far.
If you can boot your Mac, you can easily grab the serial number: Select the Apple menu in the upper left corner of your screen, and then select About This Mac. This action displays a dialog box with information about your computer, including its serial number. You can select the serial number, and then copy/paste it wherever you need it. If you can’t boot the Mac, things are a bit more difficult. You should be able to find the serial number printed on the body of the Mac, somewhere.
For most laptops, you’ll find it with the copyright information on the back of the computer. Get out your magnifying glass—the text is very small—but it’s there. If the type has worn off, or if you simply can’t read it, you’ll have to dig deeper. If you have the original box your machine came in (you kept that box, didn’t you?) it’s printed on the box itself. If you don’t physically have the Mac, you may still be able to find the serial number. If you signed into your computer with your Apple ID, you tied your computer’s serial number to your Apple ID account, and you should be able to find information about it by logging into the Apple ID account web site ([https://appleid.apple.com/]). If you enabled the Find My Mac feature on the Mac, you should be able to log into your iCloud account (http://www.icloud.com) and find the serial number there. Hopefully, one of these options will help you get the information you need.
