How to repeat a key in mac while holding down? [duplicate]
Solution 1:
There is a terminal command to set the option. Go to terminal and type
defaults write -g ApplePressAndHoldEnabled -bool false
This actually turns it on. You have to restart your computer for this to take effect. You turn it off by typing the same line with true instead of false.
defaults write -g ApplePressAndHoldEnabled -bool true
