Your Mac disables Apple Pay when certain security settings are modified, or when it detects third-party software or malware that affects its ability to keep your payment information secure.
Make sure that your notebook lid is open
To use Apple Pay on supported Mac notebook computers, your computer's lid must be open, not in closed-display mode.
Check security settings
Check for the latest software updates
For the strongest security, install the latest Apple software updates.
To make sure that you always get important security updates promptly, keep the “Install system data files and security updates” setting enabled in Software Update preferences:
- Choose Apple menu > System Preferences, then click Software Update.
- Click the Advanced button.
- Select “Install system data files and security updates.”
Security updates help make your Mac more secure by identifying malicious software and preventing its installation. When you restart your Mac, they also remove any malicious software that is identified and already installed.
If you still get the same Apple Pay alert after installing all available software updates and restarting your Mac, contact Apple Support for help.
In China mainland, you can use Apple Pay on the web in Safari only on compatible iPhone and iPad models using iOS 11.2 or later.
