Apple released a refreshed MacBook Pro this week and top among the new features is a tweaked keyboard. Apple says its quieter than the last version and in our tests, we agree. But iFixit found something else: thin, silicone barriers that could improve the keyboard’s reliability.

This is big news. Users have long reported the butterfly switch keyboard found in MacBook Pros were less reliable than past models. There are countless reports of dust and lint and crumbs causing keys to stick or fail. Personally, I have not had any issues, but many at TechCrunch have. To date Apple has yet to issue a recall for the keyboard..
