Use Apple Pay on your Mac
You can make easy, secure, and private purchases on websites using Apple Pay on your Mac Pro. With Apple Pay, your Apple Card and other credit or debit card information is never stored or shared by Apple with the merchant. When you shop online using Safari, look for an Apple Pay checkout option. Confirm payment using your iPhone, Apple Watch, or a Magic Keyboard with Touch ID.
Note: Apple Pay and Apple Card aren’t available in all countries or regions. For information about Apple Pay, go to Cashless made effortless. For information about current card issuers, see the Apple Support article Apple Pay participating banks. For information about Apple Card, see Apple Card Support.
Set up Apple Pay. No extra setup is required if you’ve already set up credit or debit cards on your iPhone or Apple Watch. Make sure you’re signed in to your iPhone or Apple Watch with the same Apple ID you’re using on your Mac Pro. If you have no debit or credit cards set up, you can do it in the Wallet & Apple Pay pane of System Preferences.
Make a purchase with iPhone or Apple Watch. Click the Apple Pay button on the website, then to confirm the payment, use Face ID, Touch ID, or the passcode on your iPhone, or double-click the side button on your unlocked Apple Watch. You must be signed in to an iPhone or Apple Watch that has Apple Pay set up with the same Apple ID you’re using on your Mac Pro.
Note: You can add or delete payment cards and manage your Apple Card in the Wallet & Apple Pay pane of System Preferences.
