Mac computers are known for their reliability and user-friendly interface. However, even Macs can sometimes encounter issues when trying to connect to public WiFi networks. If you’re facing difficulties in connecting your Mac to a public WiFi network, this article will provide you with some troubleshooting steps to help you resolve the issue.

Firstly, it’s important to check your DNS settings. Alternate DNS servers can sometimes cause conflicts and prevent your Mac from connecting to the WiFi network. To fix this, open your DNS settings by going to System Preferences, selecting Network, and then clicking on the Advanced button. Next, navigate to the DNS tab and remove any DNS servers listed by selecting them and clicking on the “-” button. apply the changes and try connecting to the public WiFi network again.

If the issue persists, you can try rebooting your Mac. Sometimes a simple restart can fix connectivity problems. Additionally, pay attention to the name of the WiFi network you are trying to join. Make sure you are selecting the correct network and entering the correct password.

If you are using a VPN tool, such as ProtonVPN, it’s recommended to quit the tool and disconnect from the public WiFi network before rejoining it. VPNs can sometimes interfere with the connection process, so temporarily disabling them can help troubleshoot the issue.

Another step you can take is to check your firewall settings. Open System Preferences, select Security & Privacy, and then go to the Firewall tab. If your firewall is turned off, you should switch it back on by tapping the padlock item, entering your password, and enabling the firewall. This will add an extra layer of security to your Mac when connecting to public WiFi networks.

It’s important to be cautious when connecting to public WiFi networks as they can pose security risks. Cybercriminals can potentially intercept your data by placing themselves between you and the connection point. To protect yourself, avoid transmitting sensitive information over public WiFi and consider using a virtual private network (VPN) for added security.

If your Mac is having trouble connecting to a public WiFi network, try the troubleshooting steps mentioned in this article. By checking your DNS settings, rebooting your computer, and ensuring your firewall is enabled, you can increase your chances of successfully connecting to public WiFi networks. Remember to exercise caution when using public WiFi and take steps to protect your personal information.

1. Click on the Wi-Fi icon in the menu bar at the top right corner of your screen.
2. From the drop-down menu, select “Open Network Preferences.”
3. In the Network Preferences window, click on the “Wi-Fi” option on the left sidebar.
4. Click on the “Advanced” button at the bottom right corner of the window.
5. In the new window that opens, click on the “Wi-Fi” tab.
6. Under the list of preferred networks, you will see a checkbox labeled “Remember networks this computer has joined.” Make sure this checkbox is checked.
7. Now, scroll down and find the checkbox labeled “Ask to join new networks.” Uncheck this box.
8. Close the Advanced window and the Network Preferences window.

By following these steps, your Mac will automatically connect to any unsecured network it finds without prompting you for permission. However, please note that connecting to unsecured networks can pose security risks, as your data may be vulnerable to interception by unauthorized individuals. It is always recommended to use secured networks whenever possible, especially when dealing with sensitive information.

Why Not to Connect to Public WiFi?

There are several reasons why it is generally not recommended to connect to public WiFi. Here are some key points to consider:

1. Lack of Encryption: Public WiFi networks often lack proper encryption, which means that any data you transmit over the network can be easily intercepted and accessed by cybercriminals. This makes your personal information, such as passwords, credit card details, and sensitive documents, vulnerable to theft.

2. Man-in-the-Middle Attacks: Public WiFi networks provide an opportunity for cybercriminals to perform “man-in-the-middle” attacks. In this type of attack, the cybercriminal positions themselves between you and the connection point, allowing them to intercept and manipulate the data you send and receive. This enables them to collect your information, including login credentials, without your knowledge.

3. Rogue Hotspots: Cybercriminals can set up fake WiFi hotspots that mimic legitimate networks. These rogue hotspots often have names similar to popular networks, tricking unsuspecting users into connecting to them. Once connected, the cybercriminal can monitor your online activities and steal your sensitive information.

4. Malware Distribution: Public WiFi networks can also serve as a breeding ground for malware. Cybercriminals can inject malicious software into the network, and when you connect to it, your device becomes susceptible to infection. This can lead to various issues, including identity theft, data loss, and unauthorized access to your device.

5. Lack of Network Control: Public WiFi networks are typically open to anyone, making it difficult to control who has access to the network. This means that you may be sharing the network with hackers, eavesdroppers, or individuals with malicious intent. Consequently, your data is exposed to potential threats from other users on the same network.

Given these risks, it is advisable to exercise caution when connecting to public WiFi. If you must use such networks, consider taking additional precautions such as using a virtual private network (VPN) to encrypt your data, avoiding accessing sensitive information or conducting financial transactions, and keeping your devices and software updated with the latest security patches.


Troubleshooting connectivity issues on a Mac can be resolved by following a few simple steps. First, reboot your computer to refresh the system and clear any temporary glitches. Additionally, ensure that you are connecting to the correct WiFi network by checking its name. It is also recommended to disconnect from any VPN tools that may be interfering with the connection.

If you are still unable to connect to the public WiFi and access the internet, make sure to remove any alternate DNS servers in your network settings. This can be done by accessing the DNS tab in the Network settings of System Preferences and removing any listed DNS servers.

To enhance your security while using public WiFi, it is advisable to enable the firewall on your Mac. This can be done by accessing the Security & Privacy settings in System Preferences and switching on the firewall. By doing so, you can protect yourself from potential cybercriminals who may attempt to intercept your connection and collect your personal information.

By following these troubleshooting steps and taking necessary precautions, you can ensure a more seamless and secure experience when using public WiFi on your Mac.
