Macros Not Working

You need to provide us with a lot more info in order for us to be helpful.

Let's start with this:

  1. When something unexpected happens consistently, ask yourself what has recently changed about your system: macOS updates, new apps, app updates, and especially any untilities
  2. Always post what versions of macOS and KM you are running.
  3. See KM Wiki on Troubleshooting

If all else fails, try Start up your Mac in safe mode. Then launch KM and test your macros. If they work fine then it is something else causing the problem.
