Pay with Apple Pay in Safari on Mac
You can easily and securely shop on your Mac in Safari using Apple Pay (look for Apple Pay at checkout). Then complete your purchase using your MacBook Pro with Touch ID, iPhone (iOS 10 or later), or Apple Watch (watchOS 3 or later). If you complete your purchase using iPhone or Apple Watch, you must be signed in to iCloud with the same Apple ID as on your Mac.
Note: Apple Pay is not available in all areas.
Before using Apple Pay, set up your credit or debit card on the device you’ll use to complete your purchase.
In the Safari app on your Mac, at checkout, click Apple Pay.
You can change the credit card, shipping address, or contact information before completing your purchase.
