Authorizing iTunes on a new Mac

Hello
I've purchased my first Mac and can't figure out how to authorize iTunes for it. I have installed the latest operating system update and iTunes update. Any advice would be greatly appreciated.

Fixed!

Well I connected my iPhone to the Mac and an on screen prompt asked if I wanted to authorize the computer. So all is well.
Been a PC user for a couple decades and from what the new Mac is showing me, I'm happy for the switch.
Good luck in your posts!
