Apple Inc. is again strongly urging users of select 2015 15-inch MacBook Pro units mostly sold between September 2015 and February 2017 to stop using these machines in light of new reports confirming minor burns to users and property damage.

Apple first issued a recall for these MacBook Pros on June 20 due to batteries that "may overheat and pose a fire safety risk." This recall affects 15-inch MacBook Pros with Retina displays sold for about $2,000. It doesn't affect other 15-inch MacBook Pros or any other Apple laptops. 

More than 432,000 MacBook Pros sold in the United States are potentially affected by the recall. Another 26,000 units were sold in Canada, said a joint recall announcement from the CPSC and Health Canada. This amounts to 458,000 machines subject to recall.

Since the recall went out, the U.S. Consumer Product Safety Commission (CPSC) has said it's received 26 reports of batteries overheating in the affected MacBooks. There are five reports of minor burns and one report of smoke inhalation. There are also 17 reports of minor damage to nearby personal property as a result of the battery fires.

As of June 4, Apple said it's received one report of a consumer incident in the U.S. but there are no reports of injuries in Canada.

Apple has asked customers to stop using affected MacBook Pro models and to contact the company to get a replacement. Apple's recall program page provides details and instructions.

Owners of the recalled MacBook Pros can visit Apple's website and enter their laptop's serial number to see if their machine is part of the voluntary recall. 

Apple said it will replace the batteries for free, but customers need to take their device to an Apple Store or authorized retailer. Customers can also mail their MacBook Pros to Apple support.
