After updating Leopard to version 10.5.2 using Software Update, iSync stopped working – it flashed in the dock, but never opened 🙁

Luckily i found this dirty but awful simple trick to get it back to working:

  • open Applications folder
  • drag iSync app to your desktop
  • open iSync from desktop -> it works!
  • drag iSync from your desktop back to your Applications folder -> iSync still works and everything is back to normal 🙂
