How can I synchronize my Contacts in my iMac with those in the Cloud?

Question

I have tried to sinchronize the Contacts in my iMac,  but it doesn´t work.  I have linked my iMac to iCloud.  When I go to iCloud directly through Internet,  I can see the "Contacts" I haver in iCloud.  I have 6,624 contacts.  The list of contactas can be seen in both iCliud and on my Mac.  But when I add new contacts in my iMac  (today I added 4),  it doesn´t synchronize.  The new contacts do not appear in the Cloud.  How can I establish a good link so synchronization can effectively take place?  Chaparro.

Sorry.  This is the answer to your observation.
I checked your point and in my Address Book I found 2 categories:
"All Contacts"
"All iCloud"
I didn´t find anything else.  I am sinchronizing from  "All iCloud".   In both cases,  my data base of contacts is 6,563 contacts.  This is the "baseline-data",  since yesterday I did succeed in sinchronizing my iMac,  my Mac Pro,  my iPad and my iPhone in order to share this database.  So my first step was a success.  I did succceed in sinchronizing all 4 devices to share the same Contacts List  of 6,563 contacts.
Then I added 11 new contacts to my main computer which is the iMac,  increasing the database to 6,574.  Surprisingly,  the iMac interacts perfectly well with the MacPro,  since thay are less then 10 feet away in the same room.  So I got full and "real-time" direct sinchronization between the iMac and the MacPro.  But the 11 new contacts have not shown up in iCloud.  And more then 24 hours have gone by,  and the sinchronization with iCloud is not taking place,  despite the fact that the INITIAL sinchronization did take place successfully.  Since the 11 new contacts have not shown up in iCloud,  they don´t show up in the iPad or in the iPhone either.
