How do I restore Reminders from a Time Machine backup?

Hey. I solved the problem by restoring the ~/Library/Calendars folder with Time Machine on MacBook. Hope this helps you.

OS X Yosemite version 10.10.1

I recently lost most of the contents of my Reminders. Although I can't be sure of the cause, I suspect a certain Mac cleaning utility.

I was able to restore my Reminders with the help of Apple Support, but the procedure was not straight forward as the ~/Library/Calendars folder “contains account data and generally speaking it will cause iCloud to activate even if deactivated and remove the data since the time stamp on the data is older than on iCloud”.

Here is the procedure that I followed:

1. Disconnect from Internet

2. Make a backup of your current ~/Library/Calendars folder

Locate Calendars folder using Finder

• List the folders in your Home folder
• Click on Go → Hold down alt key to see Library → Click on Library → Click on Calendars

Copy the Calendars folder to Desktop

3. Locate Calendars folder in Time Machine

Locate Library folder using Finder

• List the folders in your Home folder
• Click on Go → Hold down alt key to see Library → Click on Library

Enter Time Machine

Locate Library folder for the day/time you want to restore

Click on Calendars folder

4. Restore Calendars folder

Then Restart and check your Reminders to ensure that they are OK

5. Make a local backup of your Reminders

Export each Reminders list to (say) Desktop

Reminders → File → Export

6. Reinstate previously saved Calendars folder

Locate Library folder in Finder

Copy saved Calenders folder from Desktop into Library folder (over-writing previous Calendars folder)

Restart

7. Update Reminders from local backup

Import each Reminders list from Desktop

Reminders → File → Import → select backup file → select appropriate Reminders list

8. Reconnect with Internet
