All data has been collected from assorted Apple Genius Bars in the U.S. that we have been working with for several years, as well as Apple-authorized third-party repair shops.
The 2014 MacBook Pro model year saw 2120 service events in the first year, with 118 related to keyboard issues necessitating an upper case replacement -- 5.6 percent of all MacBook Pros serviced in the first year. The 2015 has 1904 service tickets, with 114 relating to the keyboard, making 6.0 percent.
The two numbers are very similar, which is to be expected. The keyboards were essentially unchanged since the 2012 Retina MacBook Pro, and should have failure rates similar to each other.
Apple released the new keyboard with the MacBook, and moved the design to the
2016 MacBook Pro. In the first year of the 2016 MacBook Pro, our data gathered 1402 warranty events, with 165 related to only the keyboard and not including the Touch Bar -- 11.8 percent.
We don't have a full year of data for the
2017 MacBook Pro yet. But, since release in June 2017, our data set has 1161 captured service events with 94 related to keyboard issues also not including any Touch Bar issues -- 8.1 percent.
Failure rates across all four models are relatively static, with no appreciable increase or decrease in events reported at any time after release. Percentages of failures were comparable between the third-party authorized shops, and the Genius Bar data.
