Lately I have noticed that my mechanical keyboard started to chatter/bounce characters. I do not fancy the idea of buying a new keyboard or resoldering switches on 1 year old clicker. Looking into other solutions, I have stumbled upon various software fixes, but all for Microsoft Windows. I needed something for MacOS. Currently I am experimenting with lower “Key Repeat” and “Delay Until Repeat” settings. I had them at max for a long time, but now I have tuned it down a notch to see if it helps the double keystroke problem. It is a minor inconvenience as key repeat takes longer (visible when deleting walls of text), but I can live with that if it solves the problem.
