Turn up your sound and listen to the difference.
The spacebar on my new MacBook Pro 2016 doesn’t work as intended in the right area of the key. It only registers clicks every now and then and feels very spongy/sticky to use compared to left side (and every other key).
This is the 2nd unit I’m on – the first one had the exact same problem.
Update: swapped to a 3rd unit which doesn’t have this problem. Happy to finally be out of the swapping loop. Apple, please get serious about your quality control!
