Contacts has a mind of its Own
Next I laboriously deleted about 200 contacts that appeared twice, plus those I no longer required.
Then I read that when there are entries on the Mac and in the cloud then these appear twice in All Contacts and so I had supposedly deleted some in the cloud and some on the Mac and would then had two incomplete contact lists!
Things get a bit hazy after that.
Later I deleted all the contacts on my phone and synched with the cloud.
Now I look at my computer and mysteriously everything is back. In fact I can delete the same contact from those All on My Mac list and All iCloud list and it reappears in the cloud list again.
But what is more important having synched my phone with the cloud not all the contacts appear although according to the Mac they are both in the cloud and on my Mac! I have spent some time researching “synchronising and deleting contacts” on the internet without success.
I am left with 500 cards on my Mac, 415 in the cloud and 233 on my phone! (I don’t know whether the Mac additional counts cards I have in local lists)
I think I will have another try on the weekend but if anyone has ideas of where to look or useful articles I would appreciate it.
