iPhone stuck while trying to connect to my MacBook

I'm sorry but I'm a bit confused. The subject line says you're having trouble connecting your iPhone to your Mac. However, the body of the post says you're trying to set up your Mac and can't enter card details.

Can you please explain, step by step, what you're trying to do and what happens when you try.

when I had to insert card validation it got stuck

What does that mean? What card? What were you validating? Were you trying to set up Apple Pay?

I turned on Mac again and it opened normally… did I missed any settings?

Is everything working as you'd expect? If so, I'd say not.

Did it connect properly with my iPhone/apple id? Should I reset it and do it all over again?

Go to System Settings. Do you see your Apple Account at the top of the sidebar? Is it the same one that's on your iPhone?

You can go to System Settings>Wallet & Apple Pay and check to see if the card was properly added. If not, tap the Add Card button and start over.
