puzzling behaviour: contacts and notes
I have two separate problems with iCloud on my iMac.
1 My contacts are duplicated 8 times on my iMac - when I open the Contacts app, everything appears 8 times (all the names, folders etc) and for each contact there are 8 iCloud cards.
This doesn't happen on my Air, nor on my two iPads, which all function correctly.
When I go to my iCloud via Safari, there is also only one copy, as there should be.
2 My Notes don't update on my iMac - any notes made on another device (eg my Air or iPad) do not appear in the iMac's Notes app under the iCloud heading.
Again, my Air and iPads both function correctly.
Clearly, something is amiss on my iMac, but I can't find any troubleshooting procedure for it. It isn't question of resolving duplicates - all 1016 contacts are duplicated 8 times, but looking for duplicates finds only about 150.
Can anyone help?
Thanks!
I'm in Mavericks 10.9.2.
