Wyoming | You're lucky in that you've gotten more than 10 years out of your Mac. But getting more than five years isn't unusual at all for a Mac laptop. I have a Macbook pro from 2013 that I still use nearly every day. I have to put a new battery and keyboard into it.
I'd say that there is something running on your Mac that is swamping the CPU, and that's what is causing the delay in keystroke echoing. I'd open the Activity Monitor and find out what is running. |
