Apple has not only improved the processors within its existing MacBook Pro models but has also improved the keyboards that these refreshed laptops offer. Over several years, Appleās MacBooks have had keyboard issues with missed and repeated key presses on the Butterfly keyboards used in MacBooks from the 12-inch version to the MacBook Pro.
Apple has been working to address the keyboard issues for some time, without success, issuing an apology and even recently extending its keyboard repair program to cover all MacBooks with Butterfly keyboards, though recent change may mean this is no longer necessary. The difference seen is that Apple has used a different material in its switch covers. These are meant to keep debris away from the actual key switch that registers inputs. The new cover is now made of nylon, while the old cover was mostly polyacetylene with aromatic urethane side groups. Apple may also have made a change to the metal dome switch itself, though this still remains unconfirmed. Apple has not yet commented on these revelations, and it is still uncertain if the changes will work.
