MacOS Connectivity Restore

Purpose

This skill restores the two settings we previously repaired on this Mac:

  1. Universal Control / Link to Mac or iPad
  2. AirDrop availability plus AirDrop receiving mode

It is designed for managed Macs where these settings are forced by files under /Library/Managed Preferences.

What This Skill Changes

Root-level managed preferences:

  • com.apple.universalcontrol.plist
    • Disable = false
  • com.apple.applicationaccess.plist
    • allowUniversalControl = true
    • allowAirDrop = true
  • com.apple.NetworkBrowser.plist
    • DisableAirDrop = false

User-level preferences:

  • com.apple.sharingd
    • DiscoverableMode = "Contacts Only"
  • com.apple.NetworkBrowser
    • DisableAirDrop = false

Scripts

  • scripts/restore-root.sh
    • Run as root. Fixes the managed preference files under /Library/Managed Preferences.
  • scripts/restore-user.sh
    • Run as the logged-in user. Sets AirDrop receiving mode to Contacts Only.
  • scripts/install-startup.sh
    • Installs a LaunchDaemon and LaunchAgent so these settings are restored automatically after reboot/login.

Default Workflow

When the user asks to reapply these settings:

  1. Run scripts/restore-root.sh <username> with admin privileges.
  2. Run scripts/restore-user.sh.
  3. Read back the values to verify:
    • allowUniversalControl = 1
    • allowAirDrop = 1
    • DisableAirDrop = 0
    • DiscoverableMode = "Contacts Only"

Persist Across Reboots

When the user asks to make the change stick after every reboot:

  1. Ensure this skill has been installed to a stable path under ~/.claude/skills/macos-connectivity-restore.
  2. Run scripts/install-startup.sh.
  3. Confirm these startup items exist:
    • /Library/LaunchDaemons/com.joseph.macos-connectivity-restore.root.plist
    • ~/Library/LaunchAgents/com.joseph.macos-connectivity-restore.user.plist
