The 2018 MacBook Air logic board problem is one that’s been highlighted by Apple and luckily, the problem is nowhere as severe as the battery overheating problems emanating from the 15-inch MacBook Pro. While the exact issue remains under wraps, customers who currently own the 2018 MacBook Air can choose to take their machine to an Apple Store and eliminate the problem before it worsens.

According to an internal document distributed to Apple Stores and Apple Authorized Service Providers on Friday, the MacBook Pro logic board issue exists for only a small percentage of notebook owners. In order to retain its image of providing impressive after-sales customer support, Apple will reportedly replace the main board in affected MacBook Air units, and that too, free of charge.
