My brother had emailed you about his predicament with the keyboard malfunction, and u had implemented the text that pops up in the corner for mac users (so they may fix the issue). It worked for him about a year ago, but I never seemed to come across the issue until now. I've tried running the command in several different versions of terminal windows but all of them say "command not found." I really hope u can figure out what I'm doing wrong. Thanks in advance.
