My macbook pro is running 10.10.1 and has stopped syncing reminders and calendar events to iCloud.

Question

My macbook pro is running 10.10.1 and has stopped syncing reminders and calendar events to iCloud. Changes made to iCloud directly DO update to my machine, so the communication issue is one way only. When I make a change to the calendar or reminders on my machine, it will often bog down and run slowly. I have done several trouble shooting steps without result. these include:
Restarting my computer.
Running Disk Utility diagnostics for both permissions and disk verification.
Checking that my internet and network is working.
Checking that I am properly logged in to iCloud with my ID on my machine and that I have set everything to sync.
Checking my iCloud settings to stop syncing Reminders and Calendars and then setting them back to sync again.
Any suggestions?

Answer 1

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.
