Data transfer appointment for new MacBook

You're not communicating with Apple when you post in the Community. Apple does not participate in these forums. We're all just fellow users, helping out as we have time and knowledge to share, so no one here can make appointment for you. You need to go to the website of the Apple Store you wish the appointment with and use their appointment scheduling feature.

Regards.

This is a user to user forum. We do not make appointments here.

You can set up a Genius Bar appointment in the following website.

click here ➜ Genius Bar Reservation and Apple Support Options - Apple

With that said, in general it's fairly simple to get data transferred yourself.
