Use Wallet & Apple Pay on Mac
If your Mac has Touch ID, you can use it to make payments on websites that support Apple Pay. To set up Apple Pay on your Mac, you need to add at least one credit, debit, prepaid or store card to Wallet. If you already have a debit or credit card associated with the iTunes Store or App Store, just verify your card’s security code to add it to Wallet.
You can view a list of recent transactions for each card you add to Wallet. (Not available for all cards.)
Set up Apple Pay on your Mac
On your Mac, choose Apple menu
> System Preferences, then click Wallet & Apple Pay.Click Add Card.
If you’re not signed in to iCloud, you’re asked to sign in. Once you’re signed in, return to Wallet & Apple Pay.
Enter your payment information.
Use a card on file: If you have a credit or debit card on file with Apple for making purchases from the iTunes Store or App Store, enter the security code when prompted.
Add a new card: Position your card in front of your computer’s camera so that it appears within the frame shown on the screen, then follow the onscreen instructions. Or click Enter Card Details Manually, then provide the requested information. Repeat for each card you want to use with Apple Pay.
Important: If you sign out of your iCloud account, you have to set up Apple Pay again — including adding any cards you’ve added in Apple Pay on your Mac.
Make purchases
When checking out from an online store, click Apple Pay. If you have more than one card on file with Apple, you can choose which card to use. You can also enter a new shipping address and contact information.
Place your finger on Touch ID to complete the purchase. If you haven’t set up Touch ID, you can tap the Pay button in the Touch Bar and enter your password.
Note: If the lid on your portable computer is closed and you can’t access Touch ID, you must complete your purchase using iPhone or Apple Watch and a card associated with that device.
If you haven’t set up Touch ID, see Set up Touch ID to set it up.
View transaction details
On your Mac, choose Apple menu
> System Preferences, then click Wallet & Apple Pay.Select a card, click Transactions, then select the tickbox beside “Show transaction notifications from”.
The most recent transactions associated with the selected card appear on the right. This list may include only transactions made on this Mac, or all recent transactions, depending on the card. (Transactions aren’t available for all cards.)
Only one user account on your Mac can use Touch ID to complete purchases made with Apple Pay. (Other users can complete their purchases using iPhone or Apple Watch and a card associated with that device.) If you want to allow a different user to use Apple Pay with Touch ID, the new user is prompted to reset Apple Pay when they choose Apple menu > System Preferences and click Wallet & Apple Pay.
