I remember back in the day (like 90’s) there was significant latency noticeable on Macs when typing. Today if I have any problem with my hardware keeping up with my typing, it’s probably radio related. My Logitech MX Keys will stop buffer and then barf out a crap tone of letters, sometimes more than just my backlog. Not sure what that’s all about but I understand others have had similar problem with the keyboard. It’s not frequent enough to give up the otherwise great keyboard, and it’s worse over Bluetooth than Logitech’s wireless protocol.
