This isn't the first recall that's been made for a MacBook-related component or accessory. In June, Best Buy recalled MacBook Pro replacement batteries after the US Consumer Product Safety Commission received 13 reports of battery fires. In 2011, Apple recalled MacBook MagSafe power adapters that were prone to splitting.
