According to a patent application made public on Thursday, March 8, Apple could be developing a new MacBook keyboard designed to prevent crumbs and dust from getting those super-shallow MacBook keys stuck. "Liquid ingress around the keys into the keyboard can damage electronics. Residues from such liquids may corrode or block electrical contacts, getting in the way of key movement and so on," the patent application reads. Digital Trends reports: The application goes on to describe how those problems might be remedied: With the careful application of gaskets, brushes, wipers, or flaps that block gaps beneath keycaps. One solution would include a membrane beneath each key, effectively insulating the interior of the keyboard from the exterior, while another describes using each keypress as a "bellows" to force contaminants out of the keyboard. "A keyboard assembly [could include] a substrate, a key cap, and a guard structure extending from the key cap that funnels contaminants away from the movement mechanism," the patent application reads.
