📄 Description

On macOS if you are running the barrier server and you remove the accessibility permission in System Preferences, your computer becomes unusable. You are able to move the mouse pointer around, but no clicks go through and none of the keyboard input either. I had to manually restart my computer using the power button. I guess what happens is that barrier continues to capture the input, but can't forward it on as the accessibility permission has been removed.

My fix is to periodically check if the accessibility permission is enabled and if not, terminate the application. MacOS provides no API to be notified when this permission changes, so we have to basically poll it. The fix currently checks every second, but only when barrier is started.

Contributor Checklist:

I have created a file in the doc/newsfragments directory IF it is a
user-visible change (and make sure to read the README.md in that directory)
