Options after MacBook Air returned with faulty keyboard
My mom is the original owner of a MacBook Air (Retina, 13-inch, 2018) which should be covered under the "Keyboard Service Program for MacBook, MacBook Air, and MacBook Pro".
Recently, the "e" key started to bounce and unexpectedly produce 2-3 characters with a single key stroke. However, the issue is intermittent and sometimes she can go 20 minutes without it occuring.
We made an appointment with the genius bar, who took the laptop and sent it in for repair. However, Apple was unable to replicate the issue, they stated that the repair was complete, and sent the laptop back with the same faulty key.
What can my mom do to prove that this fault exists, so that she can receive the repair she is rightfully eligible for?
