Have you read this post:
I think you are missing something important from your list. For four out of the five items that you listed you didn't indicate if the entry was "Keyboard Maestro" or "Keyboard Maestro Engine." It could indeed be a permissions problem. I don't know what you "should have" because I'm not an expert at permissions, and I don't know which version of KM you have. I'm just trying to help you if the mistake is a simple one. If it's a deep problem, you may have to open a ticket with Stairways.
You said "the macros are not triggering in the log at all." Are any macros triggering? If not, then maybe the problem is that the Engine isn't running. What kind of things do you see in the log? Is there anything in the log with today's date? Do you see the KM Engine icon in the upper right corner of your screen? I know you may be upset that I would ask such a question, but this has happened to people before. I'm forced to ask these questions because they could be the problem.
Sometimes the scope of a problem is bigger than what we first think. You said there were two things not working, but maybe there are many more things not working. Can you make a macro that "beeps" when you press a key? Will that run?
If you don't like the questions I'm asking, then you can ask me to stop and wait for someone else to offer help. I won't be offended.
