I had the same problem with a Macbook Retina 2014 running El Capitan 10.11.6. The problem started after downloading a Skype update, although can't be positive if there's a direct link. I tired the sudo killall VCDAssistant fix which was ineffective, then your safe-mode fix, which worked like a charm. Thanks for the info!

I have same problem and after 7 calls to Apple support, I still have this issue.

Same problem here. Very annoying. MacBook Pro Late 2011. Problem only started after upgrading to Yosemite.

I am now engaged with my second senior technician from Apple in an attempt to resolve this issue. So far, no one has been able to. This issue only appeared after I installed Yosemite.

Ed,

My experience is in every way the same as yours as described in your initial post. It does not seem to matter what programs are running or what time of day etc... It seems entirely random. My numerous calls to Apple have resulted In my dumping tons of unwanted files, programs, cache and other junk from my IMac and still the message pops up.

I am now waiting for the Apple senior tech guy ( who seems really outstanding in every way ) to get back to me when he returns to the office.

I have the same problem. Does anyone else also have a problem with Messages and Facetime? iCloud works fine for syncing notes etc, but I still get the error message from time to time.

Then there is the problem of not being able to log on to Messages and Facetime at all. No error messages, just never make it past the log-in step. Wonder if these two problems might be related..?

I also have this problem on Yosemite. I use all items, but I have also removed individual items and no matter what I use or what I leave out, the error message still occurs. I had this very same problem with Mavericks when it first came out, but the workaround for that does not work with the problem now on Yosemite.

Apple need to get this problem sorted or their big plan for iCloud will be of no use at all. Come on Apple please sort it out.

I too have this message pop up when I am using the MacBook Pro since upgrading to Yosemite.I never get on my iPhone 5, but always on my computer. I notice it happens a lot(but not entirely exclusively) with iTunes.

I have been discussing this problem with a senior Apple technician and he has told me just a little while ago that the engineers at Apple are aware of this problem and expect a software update to be forthcoming.

I don't think Apple 'Cloud' is ready for prime time. I have not been able to log on at all for over three years of attempts now. It tells me 'Not Authorized' and says it will send me an email with instructions. I have yet to receive an email. I've given up on it.

Hello EdMartin, I have the same problem, although something doesn't syncing well on my Mac and iPhone: the Safari history.

With Yosemite and iOS8, Safari history should sync between devices. It did for almost a month and now it doesn't work and I've this message.

It happens when I close Safari or when I delete history on my Mac to try to "reset" it on iCloud and see if it works again.

Maybe you have feature of iCloud not working, when my Safari history was working like a charm, I never had this **** message.
