how can i watch DVD, on MAC Pro

Greetings, Vansrans45!

Welcome to Apple Support Communities! From your post, we can see you'd like to watch DVD's on your new Mac.

You'd need to have an external drive. The Super Drive might work for you: How to connect the Apple USB SuperDrive. Please note in this guide you'll see you'd need an adapter to connect the drive.

Prior to purchasing it, we'd suggest talking or chatting with a sales specialist to make sure it will work with your specific model: Apple sales.

All the best.

Vansrans45,

Thanks for the clarification. There wouldn't be a way to connect a DVD drive to an iPad or an iPad Pro.

Kind regards.
