iCloud-specific calendars are not syncing to my computer...

The issue:

My iCloud-specific calendars are not syncing to my computer—instead Calendar.app keeps returning a rather cryptic error message. I have tried multiple things and I can't seem to solve this syncing issue. I don't really know when this error started but it's really annoying. 🙂 I'd really love any help figuring this out!

Whenever I launch Calendar.app, I keep getting an error that looks like this:

The server responded with an error.

The request (CalDAVMigrateToServerQueueableOperation) for account “iCloud” failed.

Screenshot of the error message:

What have I done so far to zero effect:

I have signed out then re-signed into iCloud on my MacBook.
I have signed out then re-signed into all my Internet Accounts in the System Preferences.
I have repeatedly toggled the preferences to sync calendar events in iCloud preferences pane.
I have restarted my computer pretty every time I tried to fix it.
Checked to see if the Calendar app on iCloud.app as well as my other Apple devices is syncing the iCloud-specific calendars correctly (spoiler, they are working perfectly fine. Just not working on my computer.)

Relevant Specs:

MacOS Mojave 10.14 (18A389) running on a MacBook Pro (15-inch, 2018).

Calendars are synced:

iCloud Family & Work calendars (syncing does not work)
A personal Google gmail account (syncing works)
A business Google GSuite account (syncing works)

MacBook Pro TouchBar and Touch ID, macOS Mojave (10.14), null

Future people who stumbled across this post...as soon as I submitted this giant post—I managed to fix the syncing issue. ¯\_(ツ)_/¯

It looks like I had a corrupted .plist file for Calendar.app. To fix that, all I did was:

Toggle hidden files with handy three-key shortcut: ⌘+shift+.
Navigate to /Users/your-username/Library/Preferences/
Search and delete these files:
- com.apple.CalendarAgent
- com.apple.iCal.plist
Restart your computer!

If you still see the hidden files (the file icons will be greyed out) and they are annoying you, just use the three-key shortcut again. The files should be be hidden again!

Like a few others who responded recently, I find neither of those files in my Library. This isn't happening on my iMac (yet, at least) - but it's been going on, on my MacBook, ever since Mojave was installed. Driving me nuts. Help would be appreciated.

I have not found either file on my MacBook Pro and this issue happened right after I installed Mohave. I continue to get the Calendar error message, "(CalDAVMigrateToServerQueueableOperation) for account “iCloud” failed."

I was able to use the process you described, but I only found the .iCal.plist file, and could not locate a .CalendarAgent file. I dragged what I found out onto my desktop. I had to force a full shut down because the computer was hanging up on a restart - but it successfully reopened after the forced shut down. Not sure what to do about the file I can't find - but maybe this will help. I'll let you know.

I continue to have this problem too. I have done thorough searches for the iCal.plist and CalendarAgent suggested by others and have had no luck finding them. This problem all began immediately following my upgrade to Mohave OS. Now I'm stuck with it with no resolution in sight!

For what it's worth, I coudn't find either until I entered the command in the terminal app that some of the posts in this discussion lead you to. Then, I found the "plist" file in the Library, and dragged it out onto my desktop, but still had no "CalendarAgent" file in the Library. However, interestingly, since the "plist" is no longer in the Library, the message has stopped (about 36 hours now). So maybe this worked.

Even though I only found the .plist file and not the .CalendarAgent file after I "exposed" my hidden files, still just dragging the .plist file out of the Library did the trick, it appears - it's been about 72 hours now and no more irritating messages! THANK YOU very much!

I have exactly the same issue. I deleted my iCal.plist, but I cannot find a file named com.apple.CalendarAgent on my computer. Also running Mojave 10.14 on a MacBook Pro.

Worked for me...thx! I did have to get rid of all the com.apple.iCal.* files in Preferences though.

Are you sure you are looking in your user Library?

In Finder hold down the option/alt key while selecting the Go menu item. Select Library.

Thank you for responding. When I do as you suggest, I get a dropdown with various options to select - but there is not a Library in the list. Wonder what that means! Let me know what you think.
