I was facing few problems with my Mac, so I decided to do a fresh install of Mavericks:
After that, I restored via Migration Assistant using Time Machine from an external hard drive, but un-selected some stuff to migrate.
I was asked to reauthorise my Apple ID as well as its iCloud Keychain, which seems obvious. Later, I noticed that there are some permission errors that couldn't be fixed, so I decided to restore back to the previous backup using Time Machine, by restoring the entire partition.
When restoring was done, I was asked again to authorise my Apple ID and iCloud Keychain.
After using my Mac for a while, I noticed that the contacts account for iCloud is now duplicate. Also, when removing an Internet Account, it asks me if I want to remove it from this Mac, as well as 3 others, including 2 of the same name.
I thought It is an issue with liking my device to iCloud: https://discussions.apple.com/message/23621169#23621169
I tried resetting iCloud Keychain: http://support.apple.com/kb/TS4644
Few minutes ago, I noticed that the contacts has been triplicated, and my other Mac got the same issue, so probably there should be log-in certicates to iCloud that are being synched with iCloud Keychain across my 2 Macs, resulting in considering the Mac that I restored as 3 devices, and logging in to my other Mac 3 times.
Is there a way to manage the log-in certificates to iCloud from Keychain? (what do I have to for search in Keychain?)
Or do you suggest that it is better to remove all my passwords and certificates in Keychain?
