The 12-inch MacBook with Retina display is now considered vintage by Apple, which means it is no longer eligible for repair from Apple or authorized service providers.

Apple blew everyone away with the 12-inch MacBook back in 2015. Not only it was the smallest and thinnest notebook Apple had every made, but it was a technological marvel in a lot of cases. But even after its launch, it was severely marred by the weak Intel Core M processor under the hood. To make matters worse in terms of performance, it was designed to be completely fanless, something which Intel doesn't play nice with.
