CAN I MANAGE MY APPLE CARD ON MY MACBOOK PRO

Yes. Go to https://card.apple.com and login with your AppleCard login to manage your account.

What do you mean by manage? I've made card inquiries visiting a website. You MBP can most certainly do that unless you are under some sort of restrictions.

You can contact Apple support using the "Get support" link at upper right of this page, but that's just visiting a website.

Or do you mean specifically for what you can do on your iPhone is there a utility on the Mac?
