Did you ever figured this out? I'm running into the same issue. I'm able to capture the screen during LoginWindow but CGEvents for mouse and keyboard aren't working.

**NOTE: I feel like I need to add more context so the question is easier to answer. My end goal is that once the user "turns on" the app it will be opened during and after login, that's where I need my prelogin agent. But also when the user "turns off" the app I need it to stop getting launched which is when I need to remove my prelogin agent in order to prevent this.
