Use Apple Pay on your Mac
You can make easy, secure, and private purchases on websites using Apple Pay on your MacBook Air. With Apple Pay, your credit or debit card information is never stored by Apple or shared with the merchant. When you shop online using Safari, look for an Apple Pay button. You can complete a purchase using Touch ID on your MacBook Air. Otherwise, use your iPhone or Apple Watch to complete the purchase. Keep reading for details.
Note: Apple Pay is not available in all countries or regions. For information about Apple Pay, go to www.apple.com/apple-pay. For information about current card issuers, see the Apple Support article Apple Pay participating banks.
Make a purchase using Touch ID. On your MacBook Air, you’re prompted to configure Apple Pay during setup. When you choose Apple Pay on a website, place your finger lightly on the Touch ID sensor to authenticate and complete your purchase.
Note: If you don’t choose to set up Apple Pay when you first start up your MacBook Air, you can set it up later in the Wallet & Apple Pay pane of System Preferences. Manage your payment cards there—add or delete cards and make updates to contact information.
