Rain,

You might try these steps.
  1. In iCal, go to Subscriptions on the left and uncheck "Birthdays"
  2. In iCal, go to Preferences in the Menubar
  3. Go to General, and uncheck "Show Birthdays calendar"
  4. Quit iCal
  5. Relaunch iCal
  6. Go to iCal Preferences and checkmark "Show Birthdays calendar"
  7. Make sure "Birthdays" is checkmarked again under Subscriptions
  8. If you do not like the new default color, highlight "Birthdays" and then use Command + i to get "Birthdays" Info. Use the up/down arrows in that window to select the color you prefer.


Back up everything you can't afford to lose: documents, mail, movies, music, photos, and other data and settings.
