Use Apple Pay on your Mac
You can make easy, secure, and private purchases on websites using Apple Pay on your iMac. 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 or Apple Watch.
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. 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 iMac. The default payment card, shipping, and contact information that’s set on your iPhone or Apple Watch will be used for purchases on your Mac.
Make a purchase. 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.
