    Greetings,

     

    Questions:

    • What version of the Mac OS are you running (Apple > About this Mac)?
    • You say the information was lost when you updated iCal, but iCal is not an update you can install (It is part of OS X).  What exactly did you do on the computer which resulted in the information disappearing?
    • Do you maintain a backup of your information such as with Time Machine on an external hard drive or Time Capsule?

     

    Generic troubleshooting to try while you answer the above questions:

    1. First make an iCal backup:  Click on each calendar on the left hand side of iCal one at a time highlighting it's name and then going to File Export > Export and saving the resulting calendar file to a logical location for safekeeping.

     

    2. Go to iCal > Quit iCal

     

    3. Remove the following to the trash and restart your computer:

    Home > Library > Caches > com.apple.ical

    Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)

    --- NOTE: To get to "Home > Library" in Lion: Click anywhere on the desktop and then click on the "Go" menu at the top of the computer screen while holding down the "option" key on the keyboard.  You will see "Library" in the menu.

     

    4. Launch iCal and test.

     

    If the issue persists:

    1. Go to iCal > Quit iCal

     

    2. Remove the following to the trash and restart your computer:

    Home > Library > Caches > com.apple.ical

    Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)

    Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)

    --- NOTE: Removing these files may remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.

     

    3. Launch iCal and test.

     

     

    Cheers.
