How to Check Your MacBook’s Model Number and Serial Number

To know whether your MacBook is eligible, you’ll need to know its precise model name. You may also have to provide Apple with its serial number.

To find this information, click the Apple icon on the menu bar at the top left corner of your Mac’s display. Select “About This Mac” in the menu.

All the information you need is displayed right here. Your MacBook’s model name is displayed under the version number of macOS you have installed, and the serial number is displayed to the right of “Serial Number” at the bottom of the list of information.

Which Macs Are Eligible?

Apple offers a mostly complete list of recalls, which the company calls “Exchange and Repair Extension Programs,” on its website. Check whether your Mac’s model name appears in this list:

MacBook Air (Retina, 13-inch, 2018) – Apple hasn’t listed this one on its website. However, “a very small number” of these systems have “an issue” with their logic board and are eligible for free replacement of that board. MacBook Pro (Retina, 15-inch, Mid 2015) – Some of these MacBooks are eligible for a battery replacement. The battery may overheat. Check the MacBook’s serial number to see if it’s eligible. If you have an eligible Mac, Apple advises you to stop using it immediately for fire safety reasons. MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) – Some of these MacBooks sold with 128 GB of 256 GB solid-state drives “have an issue that may result in data loss and failure of the drive. ” Check your MacBook’s serial number with Apple to see if it’s affected. MacBook Pro (13-­inch, 2016, Four Thunderbolt 3 Ports) – Some of these MacBooks have an issue with their display backlight.

MacBook Pro (13-­inch, 2016, Two Thunderbolt 3 Ports) – Some of these Macs have the same backlight problem as above.

Apple says this isn’t a safety issue, but will replace the battery free of charge of your device is eligible. Here’s how to check your MacBook’s serial number. Note that this doesn’t affect MacBook Pros with touch bars.

If You Have a Keyboard Problem

Apple says that “a small percentage of the keyboards” in some MacBooks may have problems. If your MacBook’s keyboard has characters that “appear unexpectedly,” “do not appear,” or the keys just feel “sticky” or don’t respond consistently, Apple will likely fix it for you.

Apple provides a list of affected MacBooks—new MacBooks with the much-discussed new keyboard design. If you have one of these MacBooks and your keyboard is working fine, however, Apple won’t do anything—it will just fix problems that have already become apparent:

Plug Adapters and Electric Shocks
