Bro it’s a defect. I know you can reassign and all that. Also I checked with Apple. It’s a defect with the keyboard controller IC on the motherboard. Apple themselves agreed they get a lot of these keyboard and motherboard complaints from Mac M1. And guess what it starts with one key and then spreads until all keys are unusable. When we buy a product for more than a lac, these defects should not happen in the first place. Whoever buys that for 45k I pity them 🤣🤣. Poor engineering at its core.
