Can't add cards (visa/chase & amex) to Apple Pay *only* on Macbook

Just double check this setting on your MacBook Pro.

• On your Mac: Choose Apple menu  > System Settings (or System Preferences), then click your name (or Apple ID). Click Password & Security. Next to Two-Factor Authentication, click Turn On and follow the onscreen instructions.

Yes, the computer needs to send information to the bank for the bank to verify. When the computer doesn’t receive a response from the bank, the request times out and the card is rejected. It could be a privacy/security setting or a network setting.

Have you always tried adding the card when the MacBook is on the same network? Is it possible to try adding the card from a different network? You could try restarting the router for the WiFi network.

Is your Touch ID enabled and you have Two Factor Authentication (2FA) enabled on your MacBook Pro? Do you use a VPN?

Have you tried logging into the bank’s website and adding the card via their website? I think Am/Ex allows it, I don’t remember if has supports that feature.

Oh, there are plenty of fixes. Unfortunately without troubleshooting, the fix is just one of a dozen or more possibilities.

What model number MacBook or what year is it? Is it updated to latest version of Mac OS?

I figured it would be, but just needed to confirm.

Please confirm exactly the version of iOS you’re on.

Have you ever had cards in your Wallet on this particular MacBook Pro? Was either card you’re trying to add, in any other device?
