Q: Calendar doesn't show any data and doesn't open Preference window

Calendar on OS X El Captain 10.11.1

iMac 27-inch, mid 2010

3,2 GHz Intel Core i3

16 GB 1333 MHz DDR3

ATI Radeon HD 5670 512 MB

 

Since I updated to OS X El Captain 10.11.1 my calendar on this iMac and a MacBook Air doesn't show any data and also don't open the Calendar preferences window. Data still exists on iCloud and I can visualise and change it on my iPhone.

 

I looked into similar calendar questions including one that describes how to uncheck the calendar and reminder options on iCloud but this doesn't work since Calendar doesn't even open its preference window.

 

Does somebody have an idea how to make the Calendar work again?

 

Thank you in advance.

    Please back up all data. If you have iCloud calendars, archive them by following the instructions on this page under the heading "Downloading a calendar from iCloud.com." All you need is a web browser, not the Calendar application. Do the same with any other network calendars you have, if possible.

    Before taking each of these steps, quit (force quit if necessary) the application. After taking the step, relaunch and test. When the problem is resolved (or when you complete Step 3 without resolving it), stop and close the Library folder.  

    Step 1

    Hold down the option key and select

              Go ▹ Library

    from the Finder menu bar. From the folder that opens, move these items (some may not exist) to the Trash, leaving the Library folder open:

              Calendars/Calendar Cache

              Calendars/Calendar Cache-shm

              Calendars/Calendar Cache-wal

    Step 2

    Move these files from the Library folder to the Desktop (again, some may not exist):

              Containers/com.apple.CalendarAgent (and any others with a name beginning in "com.apple.Calendar")

              Containers/com.apple.iCal (and any others with a name beginning in "com.apple.iCal")

              Preferences/com.apple.CalendarAgent.plist

              Preferences/com.apple.iCal.plist

    If the problem is resolved, you may be able to put back some of the items you moved in this step, relaunching and testing after each one. Eventually you may find the one that caused the problem; delete it. Recreate your settings as necessary.

    If the problem still isn't solved, put back each of the items you moved in this step, overwriting the one that may have been created in its place. You don't have to put back the files you moved in Step 1.

    Step 3

    Move this folder to the Desktop:

              Calendars

    Note: you're not moving the Calendars application; you're moving a folder named "Calendars". If there's no change, put the folder back where it was.

    If the problem is resolved after you move the Calendars folder, the event database is corrupt. You have these choices:

              Restore the folder from a Time Machine snapshot or other backup that predates the corruption.

              Use a third-party application such as Calendar Cleaner to try to repair the database.

    For network calendar accounts, such as iCloud, all you should need to do is re-enter them in the preferences. For subscribed calendars, you only need to re-subscribe.

    Hello again,

     

    thank you for your precisely documented reply. I haven't had the tima until today to follow your instructions.

     

    I went through them step by step: step 1 and 2 didn't change the behaviour of Calendar and step 3 made Calendar react as if it were my first time using it and letting me go through the "Add account" process where I added my iCloud account and activated the calendar box but no data appeared.

     

    The problem isn't resolved.

     

    It seems the only way to add or modify calendar items so far is the Safari browser iCloud page.

     

    Regards

    Peter

    Please back up all data, then take all the applicable steps in these support articles:

    iCloud: Troubleshooting iCloud Calendar

    iCloud: Advanced Calendar and iCal troubleshooting

    Nearly all sync issues should be resolved that way.

    Hello again,

     

    first, Calendar works again but without doing anything special, i.e. I didn't repeat anything neither did I apply your last instructions.

     

    Just for the purpose of sharing I think possible causes might have been one or both of the followings:

     

    1. After El Captain upgrade Photos showed a message saying it was repairing the iCloud library. It took only about 1-2 minutes and I could move around normally and close Photos. In 2 or 3 later occasions the same message was shown again and I started wondering why. When I opened Photos preferences I saw that it was uploading again about 13,000 items and I waited closing Photos until the upload had finished. I suppose the former times I closed the app too early for finishing the upload. That happened before trying again to work with Calendar.
    2. Because of a Java update I had to close and re-open again Safari.
