Contacts

Hello kofe977,

Contacts are associate with email accounts. With that in mind, only the contacts associated with your iCloud account are going to be automatically synced to iCloud.

Here is how to check:

1. Open Contacts on your MacBook Air
2. In the left column you should see all the available accounts with contacts
3. Click the different groups to see what contacts belong to each group

Contacts can be in more than one account at a time. This can be done by clicking on the account and dragging it to the account you want to add it to. You can use those steps to add any of your contacts to the iCloud account. They will then appear in the Contacts list when you go to iCloud.com.

Have a good day.

This is a user-to-user technical support site operated by Apple. Your question really has nothing to do with the title of this question. To delete messages from WhatsApp check their documentation. To delete in the messages app read this -> Delete messages on iPhone - Apple Support

Thanks for the reply, kofe977!

We're glad that helped.

We hope you have a great day. Feel free to reply if you need anything else.

Take care.

I sent a girl some message that I want to delete from my what’s app and my messages
