Mac cannot connect to Wi-Fi

Based on the limited technical details provided and without knowing which troubleshooting steps have already been attempted, I recommend starting with the following resources to help identify and resolve the Wi-Fi connectivity issue.

1. Connect your Mac to the internet

Follow Apple's step-by-step instructions for connecting your Mac to the internet using Wi-Fi, a personal hotspot, or an Ethernet connection.

2. Check your Wi-Fi router settings

If your Mac cannot connect to your Wi-Fi network, review Apple's recommended settings for Wi-Fi routers and access points to ensure your router is configured correctly.

If the issue persists after following these steps, please provide some additional details, such as whether your Mac can see your Wi-Fi network, whether it connects but cannot access the internet, or whether you receive an error message.

This will help narrow down the cause and determine the most appropriate next troubleshooting steps.
