Just a small hint to automatically sync with iCal, iSync and OmniFocus:

• Start the Terminal
• Enter "crontab -e"
• The editor VI is started. Press "i" to enter insertion mode.
• Paste the following to iSync every hour with the configured device:

  27 * * * * osascript -e 'tell application "iSync" to synchronize'

• Paste the following to sync OmniFocus with iCal a few minutes later:

  33 * * * * osascript -e 'tell application "System Events" to click button "Sync with iCal" of tool bar 1 of window "OmniFocus" of process "OmniFocus"'

  Make sure that the iCal sync button is in your OmniFocus toolbar!
• Press the Escape key and type :wq and finish with the enter key to quit the VI editor.
• That's it: iCal will sync with your mobile every hour at 27 minutes, OmniFocus will sync with iCal every hour 6 minutes later.
