Apple said on Tuesday it will repair typing-related problems in keyboards for laptops including newer versions of MacBook, MacBook Air and MacBook Pro models.

The company has determined that a "small percentage" of the keyboards in certain MacBook, MacBook Air, and MacBook Pro models may exhibit one or more of the following behaviors:

• Letters or characters repeat unexpectedly
• Letters or characters do not appear
• Key(s) feel "sticky" or do not respond in a consistent manner

Apple or an Apple Authorized Service Provider will service eligible MacBook, MacBook Air, and MacBook Pro keyboards, free of charge. The type of service will be determined after the keyboard is examined and may involve the replacement of one or more keys or the whole keyboard.

To identify your computer's model and to see if it is eligible for this program, choose Apple menu > About This Mac. Eligible models are listed below.

• MacBook (Retina, 12-­inch, Early 2015)
• MacBook (Retina, 12­-inch, Early 2016)
• MacBook (Retina, 12-­inch, 2017)
  
• MacBook Air (Retina, 13-inch, 2018)
• MacBook Pro (13­-inch, 2016, Two Thunderbolt 3 Ports)
• MacBook Pro (13-­inch, 2016, Four Thunderbolt 3 Ports)
• MacBook Pro (13-­inch, 2017, Four Thunderbolt 3 Ports)
• MacBook Pro (15-­inch, 2016)
• MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports)
• MacBook Pro (15-­inch, 2018)
• MacBook Pro (15-­inch, 2019)

No other Mac notebook models are part of this program.

Apple will offer also free repairs to owners of 2016 MacBook Pros with backlight issues. The repair program covers only the 13-inch MacBook Pro model that debuted in 2016, though both the Touch Bar and non-Touch Bar versions are eligible. Repairs will be covered for four years after a laptop was first purchased.

Affected devices were sold between October 2016 and February 2018. Apple or an Apple Authorized Service Provider will service affected MacBook Pro units, free of charge.

In recent months, some owners of 2016 MacBook Pros have started to encounter an issue with their laptops’ displays, where the display backlight continuously or intermittently showed vertical bright areas along the entire bottom of the screen, or the display backlight stoped working completely.
