When I installed Yosemite, I was forced to re-add the iCloud keychain back to all of my devices. I did this quickly on my iPad and iPhone, but I am having issues doing that step on my Mac (which had the iCloud Keychain under 10.9). When I do that, I get this message: "iCloud Keychain could not be set up because there was a problem communicating with iCloud. Try turning on Keychain again."
Mac mini, OS X Yosemite (10.10)
Hey Cobalt Jacket,
Thanks for the question. I understand that you are experiencing issues with iCloud Keychain. The following resource may provide a solution:

Thanks,

I'm getting the same message. Did you ever find a solution?
What kind of garbage response was that? Refer to a support page that solves NOTHING for many of us getting the same error message.
Matt,
The solutions in that knowledge base article either don't work or don't apply.
I've seen some people on Twitter mention that they nuked their Keychain from all of their devices and started from scratch. To me, this is not a solution and Apple needs to provide a solution.
After attempting to try various workarounds, I manually saved out any credentials I had in the iCloud keychain and disabled it on all active devices. I then created a new one on an iOS device and that was OK, but I tried to add that new one to my Yosemite Mac and received the same message. I cannot even create a new one on the Yosemite Mac.
There are a lot of errors in the system console along these lines:

Cannot re-sync iCloud keychain since upgrade
