Apple has long been on a quest to make its laptops almost impossibly thin, but that darn keyboard keys always take up too much space. The visitor introduced the butterfly switch several years agone to make its MacBook keyboards thinner while still maintaining some degree of tactility. Still, MacBook owners quickly realized a tiny spec of grit could render any key useless. Apple may have simply rolled out a potential ready, just it didn't even bother telling anyone.

When Apple announced the new MacBook Pro, it said the butterfly switch keyboard had been redesigned to be quieter. That's squeamish considering it was weirdly loud, simply nosotros were more interested in a keyboard that wouldn't break. According to a leaked service manual, the "quieter" butterfly switches may actually be dust-repelling starting time and foremost.

The butterfly mechanism has 2 symmetrical artillery that connect to the keycap. And then, the switch fees stable, but there's fiddling movement. The arms fold downwards equally y'all press, and the central hits the contact at the bottom of the mechanism. Considering there's so little travel, it's possible for something small like a speck of dust to get lodged in the machinery and foreclose it from triggering the switch. In typical Apple tree style, the only way to correct this defect is to supervene upon the entire keyboard along with the upper case of the computer. This would be a ridiculously expensive repair out of warranty.

When iFixit took the new MacBook Pro autonomously, it noted there were now modest silicone membranes around each butterfly mechanism. Apple would have you believe this was about making the keyboard quieter, merely now nosotros know the membranes had a different objective.

According to an Apple tree service transmission obtained past MacRumors, that membrane is in that location to continue the butterfly machinery make clean and free of grit. "The keyboard has a membrane nether the keycaps to preclude debris from entering the butterfly mechanism," the document reads. It'southward sort of a silicone skirt that goes effectually the perimeter of the mechanism. If dust can't become under those arms, it can't prevent the switch from depressing.

Apple recently had to admit to the ongoing bug with defective 2022 and 2022 MacBook keyboards. It offered an extended 4-year warranty to address the outcome, only the new 2022 MacBook is not included, presumably because Apple thinks its keyboard won't break so easily. Unfortunately, getting your older butterfly MacBook repaired won't get you the new model keyboard. The 2022 keyboard is exclusive to the new MacBook.
