The Mac 911 mailbag has recently included a number of letters about missing letters—people either can’t type or encounter strange keyboard problems or other oddities.
One email began, “I am cotactig you because my Mac Book Pro keyboard has decided it does ot like to type the letter that appears betwee L ad M o the keyboard.” (Sadly, the writer even had an “n” in her name.)
These kind of keyboard problems are easy to diagnose, because Apple’s had a spate of problems with its MacBook and MacBook Pro models. It chose a new keyboard design starting with the 2015 12-inch MacBook, and then brought to the 2016 overhaul to the MacBook Pro line. Its revised its design once, but not with much improvement.
