Hi Trish,
I see that your Mac is not always updating calendar events that are created on your iOS devices. To get started with troubleshooting iCloud Calendars, I suggest going through the troubleshooting below.
After each step, check your contacts, calendars, or reminders.
You can refresh your calendars and reminders from the Calendars app:
- Open the Calendar app.
- Choose View > Refresh Calendars.
Since the iCloud Birthdays calendar updates hourly, you might not see changes to birthdays in the Contacts or Calendars app for an hour.
If you store and edit your events in iCloud instead of another account, like On My Mac, Exchange, or Google, then iCloud will automatically update your calendars. If you use multiple accounts on your Mac like iCloud, Gmail, and Yahoo, make sure that iCloud is your default Calendar account:
- Open the Calendar app.
- Choose Calendar > Preferences.
- On the General tab, make sure that one of your iCloud calendars is the default.
After setting up iCloud Reminders, you might need to quit and reopen Reminders on your Mac. Then make sure that you set up your account correctly in Reminders:
- Open the Reminders app.
- Choose Reminders > Accounts.
- Make sure that you're signed in with your Apple ID.
- Quit the Calendar and Reminders apps.
- Choose
Apple menu > System Preferences and click iCloud.
- Deselect Calendars and Reminders (or Calendars & Reminders on OS X Mountain Lion).
On OS X Mountain Lion and Mavericks, click Delete from Mac when asked.
- Close System Preferences and wait about a minute.
- Choose Apple menu > System Preferences and click iCloud.
- Select Calendars (or Calendars & Reminders on OS X Mountain Lion).
- Open Calendar and Reminders.
After you restart your computer, see if you fixed the issue.
If you still need help, contact Apple Support. You can also use these steps to remove duplicate contacts or calendars
Get help using iCloud Contacts, Calendars, or Reminders
Take care.
