iCal Debug Menu

By Richard Mallion

iCal on Mac OS X has a hidden debug menu which you can enable from the terminal by using the defaults command. Once enabled you gain 24 additional options. A lot of these features are useful for developers but quite a few are possibly useful for the end user.

To Enable:

    • Quit out of iCal and then launch the Terminal
    • Enter the following command:

defaults write com.apple.iCal IncludeDebugMenu 1

  • Open iCal again to find the “Debug” menu

Some of the extra features include:

  • Open multiple iCal Calendar windows with Command+L – making it easier to compare dates and schedules on any level
  • Change the number of weeks that appear before and after the start date in Day View
  • Show more than 7 days in a week (7, 14, 21, and 28 days)
