Since updating to OS X 10.10.3 Yosemite, my iMac calendar won't sync through the cloud with my iPhone and my iPad. The iPhone and iPad work fine.

Since updating the operating system on my iMac to OS X 10.10.3, my iMac calendar doesn't sync with my iPhone or my iPad.

My iPhone and iPad sync just fine.


Is there a setting on the Mac that needs to be changed? I've tried turning the calendar off and on in iCloud.

iMac (27-inch Mid 2010), OS X Mountain Lion

1. Calendars in the On My Mac or On My iPhone/iPad/iPod category, and calendars that sync with other network services such as Google, will not sync with iCloud.

2. 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. Please make sure you've taken all the steps and tested adequately before continuing.

3. If there are any calendars on your Mac that you don't synchronize with iCloud, export them by selecting them in the calendar list and then selecting

File ▹ Export ▹ Export

from the menu bar. Quit Calendar.

4. Triple-click anywhere in the line of text below on this page to select it:

~/Library/Calendars

Right-click or control-click the highlighted line and select

Services ▹ Reveal

from the contextual menu.* A Finder window should open with a folder selected. Move that folder to the Desktop.

5. Launch Calendar. Your calendars will initially be gone, but they should resynchronize with iCloud. If they don't, uncheck the boxes marked Calendars and Reminders in the iCloud preference pane, then re-check them.

6. Import the calendars you exported in Step 3, if any, by double-clicking the files.

7. If the issue is resolved, close the Finder window you opened in Step 4. Delete the exported files and the Calendars folder on the Desktop.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

Thank you for this information. Unfortunately, my CALENDAR still won't sync with my iPhone and iPad.


I was able to log onto a secure website, but whether my computer used Port 80 or Port 443, I don't know.


I just read through the instructions again. I show CALENDAR as my only calendar. But there was mention of a calendar of holidays in Mavericks, or Lion?

(I can't find where I read it.) I do have holidays coming up on my CALENDAR. On my iPhone CALENDAR....since updating my OS X...the holidays are coming up TWICE. Could this be the problem?


I don't know where to look to find the source of this information.


Thank you!!

I'm having the same problem since I migrated to a new iMac running Yosemite. Previously, my calendars and reminders were syncing seamlessly across iPhone, iPad, iMac and MacBook Air running Mavericks. Now, changes that I make on my iPhone or iPad are synced correctly to iCloud and iMac/MacBook. But changes I make on the new iMac don't get pushed out to iCloud. You say "calendars that sync with other network services such as Google, will not sync with iCloud." My calendar is set up to sync with my workplace Microsoft Exchange calender - this has always worked fine in the past, but could this be the cause of the problem in Yosemite?
