Use Apple Pay on your Mac
You can make easy, secure, and private purchases on websites using Apple Pay on your Mac mini. 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 your purchase using your Magic Keyboard with Touch ID, iPhone, or Apple Watch.
Note: Apple Pay and Apple Card aren’t available in all countries or regions. For information about Apple Pay, go to Apple Pay. 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. Apple Pay uses the Apple Card or other credit or debit cards you’ve already set up on your iPhone or Apple Watch, so no extra setup is required. 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 mini. The default payment card, shipping, and contact information that’s set on your iPhone or Apple Watch is used for purchases on your Mac. If you have no debit or credit cards set up on your iPhone or Apple Watch, you can do it in the Wallet & Apple Pay settings in System Settings.
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 mini.
Note: You can add or delete payment cards and manage your Apple Card in the Wallet & Apple Pay settings in System Settings.
