Any one else having this problem? All the reminders that have shown up on my Macbook are all months old. Nothing is syncing....

Messages isn't syncing either.


All settings are turned on under iCloud on my phone.


please help?

MacBook Pro, Mac OS X (10.7)

    I have the same problem with reminders.  My calendar is syncing fine, but new remidners are not going up to the cloud, and new reminders from thec loud are not coming down to my mac.  Notes are syncing just fine, as are messages and all of the other things I'd expect.

    Firstly go to Settings/iCloud  on the iphone and just check that the individual apps are switched on to sync.


    If they are, then on the Mac, go to System Preferences/Mail, Contacts and Calendars and click on iCloud in the left column. Deleselect the service not working, then reselect it.


    If that doesn't work, just reset iCloud on the Mac. Go to System Preferences/iCloud and log out and back in again. When you log out you will be asked if you want to keep a copy on your Mac. If you do, when you log back in again, you will have a listing of things on iCloud and another under it in On My Mac. I don't like the double listing, so always select remove from Mac. Everything on iCloud will be redownloaded onto the Mac again when you log back into iCloud.


    Failing that, then the issue is most likely on the iphone. Try a restart of the phone, then if that doesn't work log out of iCloud on it and back in again. Never had to do that though to get things syncing.

    Rebooting my iPhone finally did the trick. I guess turning it off and on again really does work Thanks.

    In my case, it looks like the phone was fine / not an issue. On the Mac, I deactivated and then reactivated the iCloud sync of calendars and reminders. Then, when I re-activated it it seemed hosed with Calendar showing a CalDav setup instead of recognizing it as iCloud with push notifications. Once I restarted, however, both Calendar and Reminders seem to work fine and be properly synced. It's a bit irritating to have to go through all that, but it seems 100% fine now!

    Unfortunately, I tried everything you indicated in your post and I still have only two Reminder lists on my iPhone, Completed and Tasks.  Nothing has synced from my Reminders on the Mac.  Notes syncs, calendars sync, everything syncs through iCloud perfectly, otherwise.


    Any other ideas?



  • jdanish Level 1 Level 1 (0 points)

    Are you seeing your reminders synced on  One of the notes I found while searching essentially suggested that you need to create a list for reminders in icloud, then add reminders to that list on the mac and then they sync up and down to all devices. That's been my experience. It also allows you to create reminders that don't sync if / when you need or want to.  Good luck!

    As a matter of fact, I have created all my lists in iCloud and they are the same in both the Calendar and the Reminders.  Nonetheless, nothing shows up on my iPhone.  Thanks for the suggestion though.

    I'm having the same issues, no amount of restarting removing accounts and re-adding them seems to sort this.  Annoying as I want location reminders and I can only seem them on the device that I enter them on..

  • CliffDScott Level 1 Level 1 (0 points)

    Well, yesterday I checked the Reminders App on my iPhone and all the reminders and all the right lists were there.  I do not know what changed or have any idea about how it happened.  Perhaps i needed to sync my iPhone one more time.


    In any case, it works and I am sorry I cannot be of more help.

    Well I still have problems. If I create/delete a reminder on my iphone it sync back to my mac's reminder app. However its not working the other way around. Unless I open the iphone reminder app it never syncs from the mac to the iphone.

    I did have exactly that problem. I unchecked Calendars and Reminders on my Mac in the iCloud System Preferences and re-checked it. When you uncheck, you delete all the info on the Mac. It takes a while to re-sync, because it syncs a lot of data (at least in my case, since I have many calendars). But eventually worked for me. I can finally enter an item in my Reminders for Mac and it gets synced in the cloud and shows up on my iPhone and iPad.

    Good point. My mac reminders were not on I followed marcolac's unchecking - rechecking idea - and reminders are now getting from my mac to iCloud - and now to my phone...


    I exported the ones that were on my mac first before I did the unchecking stuff (File/Export...)- as they would have been removed forever. I imported them back in File/Import...

    Logged out of iCloud, then back in. Now all my reminders have been lost. Thanks! These sorts of problems are getting more common. Apple is starting to resemble Microsoft. Apple, please stop releasing JUNK, you are killing your reputation, and frustrating your customers.
