All Contacts disappeared after iCloud setup
I'm helped a friend upgrade from Mavericks to Yosemite today. She had not use iCloud before today.
We enabled iCloud after the Yosemite upgrade, and checkmarked Contacts, Calendar, etc., and selected "Merge."
Her contacts on her iMac are now gone.
She has no iOS devices.
She does have a Crashplan backup.
Is the best solution to restore her contacts from her Crashplan backup? Which files would I select?
iMac, OS X Yosemite (10.10.2), null
