Meteor Remote needs Accessibility on the Mac. Without it, macOS lets the pointer move but throws away clicks, keys and scrolling. Click Allow… next to Accessibility in Meteor Remote's menu bar icon, or turn on Meteor Remote in System Settings → Privacy & Security → Accessibility.
Meteor Remote needs Screen Recording. Click Allow… next to Screen Recording in Meteor Remote's menu bar icon, or turn on Meteor Remote in System Settings → Privacy & Security → Screen & System Audio Recording.
The Mac has to be on and awake, running Meteor Remote, and signed in with the same Apple account as your phone. "Keep this Mac awake while plugged in", in Meteor Remote's menu, stops it from sleeping on its own. A closed laptop lid still puts it to sleep.
On the Mac, click Meteor Remote's menu bar icon, then Change… next to the unlock pattern, and draw a new one. Changing it signs out every phone.
In the iPhone app, tap the person icon at the top right, then Delete Account.
