How can I transfer my contacts from iPhone to MacBook?

I don't know why I'm unable to do such a simple thing, I have tried everything which I could find on Google search. I want to transfer all my contacts from my iPhone to my Mac so that I can manage duplicate contacts.

Why Apple doesn't allow such an easy thing to be done with ease? Why I'm not allowed to move my contacts from iPhone to my computer.

Problems I'm getting:

1. The iCloud method: In my iPhone when I got to Settings -> My Name -> iCloud -> Contacts. The "Contacts" is already on, and I don't know what to do next.

2. The iTunes Method: When I click on "info" in iTunes tab (after clicking on my iPhone icon) I get something written like "Your contacts are shared over air via iCloud" (I don't remember the verbatim).

Please help me.

You need two devices to sync. So on Mac too, in System Preferences > iCloud, turn on Contacts sync.

Check Contacts.app > Preferences to see that account is enabled.

I don't know about iTunes method.

so that I can manage duplicate contacts.

That is not easy on Mac either. What I do is:

• On Mac, export all contacts in a vcf file.
• Upload it on https://contacts.google.com and then let it find the duplicates.
• Sort out the duplicates locally and verify it again.
• Select all contacts on the Google web interface & delete them.
