Syncing Ipad Pro to Mac laptop

You should be able to upgrade the Mac OS on your MacBook to the most current version, which is macOS Mojave.

Backup your MacBook and use the Mac App Store to up date your MacBook’s OS to macOS Mojave

Then update your version of iTunes to the most latest version to sync your iPad Pro.

Best of Luck to You!

How old is this MacBook?

If might be able to run OS X 10.11.6 El Capitán or later.

And you might be able to use this older version of iTunes ( 12.6.5 ) found here.

iTunes 12.6.5 found in this link here.

Deploy apps in a business environment with iTunes - Apple Support

iTunes 12.6.5 for the Mac requires OS X 10.11.4 or later. Not sure of Windows PC system requirement.

There are a few more things you would need to do, but do not want to add this info until we know how old a MacBook we are dealing with.

I imagine there's a question in there?

If your Mac is not capable of running the latest version of iTunes v12.9.x, you'll need to update to a MacOS which is capable of running the current iTunes version in order to sync.

If that's not your question, please write back.

MichelPM gave you the best advice. Update to Mojave, then update iTunes to the most current version and you'll be able to sync between your Mac and iPad.
