Why has iCloud stopped syncing calendar changes and reminders on my Mac with my iPhone?

Try signing out of your iCloud account and signing back in.

Sorry for what i've said randers4 you've totally true.

Thanks

You're welcome. Glad it's working now.

Don't worry about it. There is little or no documentation on how iCloud Drive works and what it's limitations are at this point. We're all learning together.

I'm on Yosemite Beta ( i'm dev but dev account is to expensive for me ( i'm student)) , i'm sorry for my bad english (i'm french ^^) , and I have learn a thing with you today.

Thanks a lot for your comprehension

You're welcome.

Many thanks. I had to go through to shutting down and rebooting my iPhone, but the calendar is synching across devices now.

Hey randers!

I was a bit confused about the iCloud Drive "not syncing" part because it kept talking about Documents & Data, and I thought by Data they meant everything else that is sync'd via iCloud. Of course, I am not about to try it to find out.... 😐

So, Contacts, Calendars, Notes, that sort of thing is not affected by iCloud Drive being turned on, correct? If so, that is a good thing to know, because I was confused.... 😢

Your friend,

Hi GB!

It's only referring to the "data" synced from iCloud-Drive enabled apps. The things you find in Settings>iCloud>Documents & Data on your device, but only for apps that are iCloud-Drive compatible (of which there aren't many right now). There's a new FAQ here: iCloud Drive FAQ. If you read it, it only talks about "storing all your documents in one place" and that once enabled, you "can't go back to using documents in the cloud". So I'm not even sure there's any "data" component to iCloud Drive beyond "documents". It doesn't hold your contacts, calendars, and other synced iCloud data.

Thanks for that clarification and the link! I shall study up on this directly! 😁

Here's another one specific to iWork for your reading pleasure: Using iWork with iCloud Drive. 🙂

Duly bookmarked and awaiting my perusal! 😍

Randers - I've got a similar problem with syncing iCloud calendar data that I'm sure could benefit from your knowledge and focus.

My problem is stated here:

Calendar Sync Problems on iOS 8 Family Sharing

I feel it would be a good idea to sign out of iCloud on the recalcitrant iPad and sign back in, as in the second part of your fix for jazzmanjohn.

Could you please have a look and see if you agree?

Thank you.

I'm pleased to report the fix outlined by Randers4 works. Here's an edited version of his instructions which I followed:

Sign out of iCloud on your iPhone/iPad and sign back in:

Go to Settings>iCloud, tap Sign Out, choose Delete from My iPhone/iPad and provide your password when prompted (your data will still be in iCloud). Then reset your phone (hold the power and home buttons at the same time until you see the Apple logo, then release); when it restarts go back to Settings>iCloud and sign back in (your data will download back to your phone. Then try syncing to your Mac (and vice versa) again and see if it works properly now.

I'm now a happy bunny!
