Un giorno il mio MacBook Air ha misteriosamente rimappato le chiavi "U", "I" e "O" per essere il tasto alt / option. Non ho idea di cosa lo abbia provocato, l'ho portato al negozio di mele e sembra che rimanga tale quando hanno fatto il test dell'hardware. Qualcuno sa perché questo potrebbe essere e, si spera, consiglia un modo per risolverlo?
Prova a ripristinare la NVRAM e l'SMC sul tuo Mac, quindi prova quelle chiavi e verifica se sono ancora rimappate.
NVRAM aka PRAM link
How to reset NVRAM
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart.
On Mac computers that play a startup sound, you can release the keys after the second startup sound. On iMac Pro, you can release the keys after the Apple logo appears and disappears for the second time.

How to reset the SMC on Mac notebooks
First, determine whether the battery is removable. Most older Mac notebooks have removable batteries. Mac notebooks that have nonremovable batteries include MacBook Pro (Early 2009 and later), all models of MacBook Air, MacBook (Late 2009), and MacBook (Retina, 12-inch, Early 2015 and later). Learn more about Mac notebook batteries.
If the battery is nonremovable:
- Choose Apple menu > Shut Down.
- After your Mac shuts down, press Shift-Control-Option on the left side of the built-in keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds. If you have a MacBook Pro with Touch ID, the Touch ID button is also the power button.
- Release all keys.
- Press the power button again to turn on your Mac.
If the battery is removable:
- Shut down your Mac.
- Remove the battery. If you need help removing the battery, contact an Apple Authorized Service Provider or Apple Retail Store.
- Press and hold the power button for 5 seconds.
- Reinstall the battery.
- Press the power button again to turn on your Mac.
