How do I put the stuff from my old Mac to my new one?

I recently got the new MacBook Pro, you know, the one where you can't plug in your iPhone. I have no idea how I'm gonna put the stuff, more specifically the music and videos, onto my new one. I tried emailing themselves to me, but it didn't work. Any other ideas?

Does it not have any USB ports? Surely you can just use an external drive.

The moment you turn on your new Mac you will see a message "Do you want to copy your stuff from your old Mac?" You must have chosen "Don't", which was a mistake.

Open Migration Assistant for a second chance to copy by Wi-Fi or by ethernet network (adapter needed) or by Time Machine backup (buy a cable to connect external drive to the Mac.

It has USB-C port (USB 3.1 spec). You just need an adapter or cable from Amazon, WalMart.com, or any shop that sells new computers and isn't living in the previous century.
