Apple today announced a voluntary recall of some 15-inch MacBook Pro units that have a battery that may overheat and potentially pose a safety risk, and is asking affected users to stop using the machines if they are impacted.
Apple says that the units were sold primarily between September 2015 and February 2017 and can be identified by their product serial number. The recall does not affect any other 15-inch MacBook Pro units or other Mac notebooks. It appears at present that the recall only applies to the 2015 model year, and how many units are impacted isn't clear at present.
To confirm which model you have, choose About This Mac from the Apple menu in the upper-left corner of your screen. If you have "MacBook Pro (Retina, 15-inch, Mid 2015)," enter your computer's serial number on the program page to see if it is eligible for a battery replacement.
The support page for the recall has details for product eligibility, and guidance on how to get the battery replaced.
AppleInsider has contacted Apple to see how many units are impacted, and has not as of yet received a response.
