Apple has determined that batteries in a limited number of MacBook Pro (Retina, 15-inch, Mid 2015) units may overheat and pose a fire safety risk. If you have that model, check to see if it is eligible for this program.
If your MacBook Pro is eligible, please stop using it and bring it in to have your battery replaced. Your device will be sent to an Apple Repair Centre. Service may take 2-3 weeks. Apple will replace affected batteries, free of charge.
To prepare your MacBook Pro for service, please back up your data. Preferably, make an appointment at one of the MR locations.
