I have launchd configured to run a script. This works fine for the user who installed it (me), but it relaunches the script every time I log in, while I'd like it to run as long as the computer is on (like a windows service).

Details - Location:

/Library/LaunchDaemons/com.pluuserwatcher.osx.test.plist

Contents:

<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>com.pluuserwatcher.osx.test</string>
    <key>Program</key>
    <string>/Users/max/Projects/PLU/Utils/userwatcher.py</string>
    <key>KeepAlive</key>
    <true/>
  </dict>
</plist>

  • Are you sure it's in /Library/LaunchDaemons? The behavior you describe sounds like it's in /Library/LaunchAgents instead. – Gordon Davisson Jul 15 '12 at 17:21
  • Yes, I loaded it with launchctl load /Library/LaunchDaemons/com.pluuserwatcher.osx.test.plist – Maxim Khesin Jul 15 '12 at 18:19

If you load the launchd item by running launchctl load ... as a normal user, it loads it for your user launchd instance (i.e. essentially as a LaunchAgent, so it only runs within your user login sessions. To load it into the system launchd (as a proper LaunchDaemon), use sudo launchctl load ... (or just put it in /Library/LaunchDaemons and reboot).
