Apple said on Tuesday it will repair typing-related problems in ‘butterfly’ keyboards for an expanded set of laptops, that include newer versions of MacBook, MacBook Air and MacBook Pro models.

The repairs would include fixing letters or characters that repeat unexpectedly, fail to appear, or keys that feel "sticky" and do not respond in a consistent manner, Apple said in a post here
