ReachDesk for Mac

1. Double-click "Start ReachDesk.command".
   If the Mac says it can't be opened because it's from an unidentified developer:
   right-click (or Control-click) it, choose Open, then click Open.
2. The first time, it sets itself up (about a minute). If it asks to install Apple's developer tools, click Install,
   wait, then double-click "Start ReachDesk.command" again.
3. ReachDesk shows a 9-digit ID. The other person enters it at reachdesk.pages.dev.
4. The first time someone connects, macOS asks for permission:
   System Settings → Privacy & Security → Screen Recording: turn on "Python" (or Terminal).
   System Settings → Privacy & Security → Accessibility: turn on "Python" (or Terminal).
   Then quit ReachDesk and start it again.
