Securing your internet connection not only safeguards your privacy but also enhances your browsing experience. For added online security, you should install a reliable VPN you can activate when required. I recommend using MacKeeper’s Private Connect VPN, which provides robust security for your Mac.

Why Turn Your Mac Into a Wi-Fi Hotspot

Turning your Mac into a Wi-Fi hotspot is a handy feature that provides a more flexible, secure, and convenient way to stay connected, especially when other options are unavailable. These advantages can be quite useful in various scenarios.

Here are some reasons why you might want to turn your Mac into a Wi-Fi hotspot:

  • 🌐 Share a single internet connection: If you have a wired internet connection on your Mac, you can share it with other devices, such as smartphones, tablets, and other computers, that do not have access to a wired connection.
  • 🏨 Convenience in limited connectivity areas: If you’re in a place with limited or no Wi-Fi, like some hotels, conference venues, or remote locations, turning your Mac into a hotspot can ensure you and others can stay connected.
  • 💰 Save on mobile data costs: If you’re on a limited mobile data plan on your smartphone, using your Mac’s connection can help you save data and avoid additional charges.
  • 🚀 Faster speeds than public Wi-Fi: Public Wi-Fi networks can be slow due to multiple users. Sharing your Mac’s connection might offer faster internet speeds.
  • 🔒 Increased security: Public Wi-Fi networks are not always secure, making you vulnerable to hackers and data breaches. You can turn your Mac into a Wi-Fi hotspot to create a more secure, private network.
  • ⚙️ Customization: When creating a hotspot, you can choose the network name, password, and security settings, giving you more control over your connection.

How to Configure Your Hotspot on Mac

When setting up a Wi-Fi hotspot on macOS, it’s crucial to know your Mac cannot receive and transmit a Wi-Fi connection simultaneously. The connection method can either input or output, not both. So, your Mac should receive its internet connection from a different source, such as Ethernet, and then broadcast it as a Wi-Fi signal.

To configure your hotspot on Mac, you’ll have to set up your shared connection according to the protocol you’ve selected. In the following section, I’ll go through each choice and the corresponding configuration steps.

1. For Ethernet

Here’s how to share an Ethernet connection via Wi-Fi on Mac:

  3. Click the Wi-Fi Options button and configure your hotspot connection.
  4. Click Start to activate the connection.

When you’re sharing an internet connection via Wi-Fi, set a strong password. Using WPA2 or WPA3 Personal as your security protocols will ensure your hotspot remains safe and protected.

2. For USB Wi-Fi Adapter

Here are the steps to share an internet connection from a USB network adapter over Wi-Fi on Mac:

  1. Plug in and set up your USB Wi-Fi adapter following the manufacturer’s guidelines.

  1. In the Share your connection from section, choose the desired source protocol.
  2. Check the Bluetooth PAN box to designate it as your sharing method.
  3. Press Start to initiate the shared connection.

After you have followed the instructions for your chosen connection type, connect your other devices to the Wi-Fi network you’ve created or directly via Bluetooth, and enjoy your Mac’s shared internet connection.
