Calendars 'unmigrated' to El Capitan

Back up the calendars then give Apple technical support a call. I had a similar problem once and they were able to give me the steps to resolve it. The deleted a couple settings files to resolve the issue. I switched to backing up my calendar via iCloud. When I switched back to backing it up using iTunes, I was unable to view anything even though I had restored a backed up copy of my calendar locally.

If you drill down into those folders, you should find a number of files with a name ending in ".ics". Double-click one of those files and see whether the calendar events it contains are imported.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen.

Click the Clear Display icon in the toolbar. Then try to import one of the ICS files. Select any lines that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name or email address, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

A folder with a name ending in ".caldav" would contain data synced with a network calendar server—that is, not "On My Mac" calendar data. Do you have any network calendar accounts? Are there any folders in there with a name ending in ".calendar"?

If that's what you prefer to do, good luck.

If you migrate your calendars to iCloud, you will run into the same issue when you try to switch back to using a locally saved and synced calendar. That is what happened to me. When I tried to switch back, I was prompted to delete my iCloud iCal. As mentioned earlier, I manually restored a local Time Machine backup of my iCal folder to my home directory / library / calendars folder. They still were not recognized in iCal on my Mac and I coudn't synchronize events to my iPhone.

I called Apple tech support. A second level agent walked me through deleting a couple settings files. I was on the phone for 20-30 minutes. It eventually worked. It has been my experience that Apple still will provide free phone support even if I am outside the initial 90-day phone support period or if my device is out of warranty. Chat-based support is also available. Begin at https://www.apple.com/support/contact/

Hi Linc,

Your replies have helped me through many issues in the past and I am hopeful that you can help me with this same problem that kpreb2 had with Calendar.

I have the EXACT same issue after upgrading to El Capitan - all of my "On My Mac" calendars no longer appear in the Calendar app on my late-2013 MBP Retina running OS 10.11, Calendar version 8.0. After following your guidance and kpreb2's steps in this thread, I, too, see an "Unmigrated" folder in Library>Calendars, and this folder contains all of the "On My Mac" calendars that were fully visible and functional on Yosemite but not after installing El Capitan. kpreb2 opted to bring the machine to Genius Bar, but I really need to get this resolved before the next available appointments in my area so I am hopeful you can walk me through possible solutions.

Your help would be greatly appreciated as always! Thank you.

exactly the same problem for me. can't import ics backups which i made before upgrade to el capitan in yosemite. i don't use icloud...bad enough losing something as important as day to day diary without worrying about what else could get lost

obviously this is just a nightmare as all work related calendar entries have gone along with everything else...but frustratingly sitting in backup files which can't be imported...

I too had this unique problem. The only way I solved it was to go into Library/Calendars/Unmigrated. In there are the old items for the 'on my mac' calendars. each of the .calendar folder contains an event folder, the nets folder has the ics files which I just selected and dragged onto the open El Capitan calendar application. These were imported. Some of the folders contained reminders rather than calendar info but the program warned me of that so I just cancelled that import.
