I have DELETED calendars showing in my iTunes Sync Calendars List!?

Hey guys, I've had this similar kind of problem as you guys did.

The reason calendars and reminders are interrelated is because they are both stored under ~/Library/Calendars as iCalendar files and probably synced as such. For me, I would see all my deleted reminders lists in Calendar and all my deleted calendars in Reminders as well. So much for making sense out of this...

What worked for me though was deleting a file used that's generated by some sync services from Apple, ~/Library/Application\ Support/SyncServices/Local/TFSM/com.apple.Calendars/data.syncdb (possibly used by iTunes).

I've also deleted all files under ~/Library/Containers/com.apple.CalendarAgent/Data/Library/Calendars/. But that might have the side effect of enabling sync of calendars on online accounts that are / have been disabled like KALLT mentioned. In my case, I do not have online accounts that does calendar syncing.

After I did this, I restarted OS X and when I got back in Calendar I had the default 'On my mac' calendars enabled a new user account gets. Then I could restore my calendars and reminders from backups correctly.

iTunes syncing with iPhone works too, but my reminders lists show up under the Calendars list in iTunes, so I had to manually deselect all of those before syncing (only have to set this once). I don't think that's normal behavior, but it's a tradeoff I'll take over messed up calendars and reminders.

I haven't had a problem since yesterday now - keeping fingers crossed it stays like that.

Thought I'd share this in case it might help someone with this mad bug... Hopefully Apple can provide a fix - they should - but I wouldn't hold my breath. With all the bugs in Apple software as of last year this is most likely not high in their priorities.

Thanks for the info. I have had this problem too.

I used your last suggestion of deleting deleted calendars in the Reminder App, and this took care of most of the problem, but not all. There are still a couple of rogue calendars. Not sure how I will deal with those yet.

Do a backup. Quit Calendar, move the ones you don't want to a folder on the Desktop, re-open Calendar and see if the result is what you want. If so, delete the folder on the Desktop.

I have exactly the same problem (Yosemite iCar/Calendar: Deleted calendar account still shown in sidebar and iTunes). Calendar seems to fail to delete all calendar data once you choose to remove an account. It’s still caching the data for some reason and thus iTunes presumes that these calendars still exist and tries to sync them back to my iPhone. Back on my iPhone I have a list of calendars that are not even supposed to exist anymore. I think there is a flaw in the Calendar application and it needs to be fixed. I wrote a bug report a while ago, hopefully it will lead to something.

As stated in the other thread: I tried deleting the corresponding folders in my user library, but it had no effect. Calendar would always restore these upon restart.

Thanks for the suggestion, this is what I was doing to prevent iTunes from syncing non-existing calendars. However, it doesn’t sit well with me that this data is still there. Calendar will retain the calendar entries locally even if you remove the calendar or account from your Mac. That just shouldn’t be happening.

Deleting the ~/Library/Calendars folder will have as a result that it will remove all your calendars, but will also enable all your cloud calendars again, even if you turned them off under System Preferences. I have multiple accounts that I don’t use with Calendars, so these are never enabled by me. However, once enabled, Calendar will download all events and keep them, even when you turn the calendar option off for that account, or even after you removed it. I assume that the only temporary option is to remove all Internet accounts, delete that folder (Calendar must be turned off with ‘Quit and Close All Windows’, so that a saved state is not generated). This should leave your calendar completely empty. Adding Internet accounts back one by one without(!) enabling calendar or reminders should prevent Calendar from downloading the data. I haven't tried this yet, but I'm willing to try.

Don’t bother with my suggestion above. It will open a can of worms.

Just to give you a taste:

* Some of my removed Internet accounts still show up in Calendar, but not anymore in System Preferences, which means that I can’t remove them anymore (since Calendar will refer you to System Preferences).

* When enabling iCloud reminders, Calendar will start uploading all your calendars, even though the option has not been turned on in iCloud settings. This not only brings us back to square one, but also just uploaded lots of data into the cloud that I didn’t want uploaded in the first place.

This is such a huge mess, unbelievable. Stay away, it’s not worth it.

The thing is, I don’t use any cloud services for my contacts or calendars, I want to keep these local on my Mac. But I have several Internet accounts under System Preferences that I use for mail only, wit the option to enable calendar syncing as well.

So in sum, I have:

* Local calendars (“On My Mac”)

* iCloud (calendar is disabled, but “Calendar” and “Reminders” calendars show up in iTunes)

* Exchange accounts (calendars are disabled and these don’t show up in iTunes)

* Yahoo (calendar is disabled, but one calendar shows up in iTunes)

* My generic IMAP provider (same thing).

* A deleted Outlook IMAP calendar, which isn’t mentioned in Internet Accounts under System Preferences, so this calendar should not exist.

In Calendar I only see my local calendars now, but in iTunes I see all calendars. It seems that iTunes also thinks that cloud-based calendars can be synced, which makes no sense to me. For instance, my iCloud calendars in iTunes have the suffix: “[AppleID@p03-caldav.icloud.com]” It’s as if iTunes attempts to sync the local data of cloud-based calendars.
