Do you know, your Mac can work or play a role as a wireless hotspot? You can connect your other devices to your MAC and share its Internet connection. It is almost the same thing as tethering your phone internet connection.

This works best if your Mac is connected to a wired network interface via Ethernet. Then you can easily connect your wireless devices to your Mac and share the wired Internet connection with them.

So in this article, we will explain how you can turn you Mac OS into a wi-fi hotspot. Follow the below method 

Enable Internet Sharing and Configure Your Hotspot

The Wi-Fi hotspot option is a component of the “Internet Sharing” feature in Mac OS X. So we will navigate to the internet. You’ll find it in the System Preferences window. So to get there
Click on the Apple menu, then select System Preferences, and click the Sharing icon.

Now select the “Internet Sharing” option in the list. Then you’ll have to select the Internet connection you want to share with the devices.

The drawback with this is that you can’t be connected to a Wi-Fi network and host a Wi-Fi network which you are going to connect your other devices to at the same time.

For instance, let’s assume your Mac is connected to the Internet via an Ethernet adapter. Then you can select Ethernet in the list at the top of the window and share that wired connection over Wi-Fi. And then if you’re connected through a Bluetooth or tethered to an iPhone device through a USB cable, you could also select them and share them over Wi-Fi.

So now in the “To computers using” box, click on or enable the Wi-Fi option. By doing this, it will create a Wi-Fi hotspot, and the Internet connection you selected at the top of the window will be shared with devices that connect to the Wi-Fi network.

Then click on the “Wi-Fi Options” button at the bottom of the window to configure or set your Wi-Fi hotspot. Now choose your preferred network name and the best Wi-Fi channel.

And ensure to click the “Security” box and select the “WPA2-Personal” and provide a password. By factory settings, the hotspot will be configured without a password and anyone will be able to connect to your Mac.

Now after you’ve finished the above steps, you can now click on the checkbox at the left side of the Internet sharing and click on “Start” to activate your Wi-Fi hotspot.  

To Share your Wi-Fi Connection

Note this, your Mac’s physical Wi-Fi interface can only either be connected to a Wi-Fi network or host its own network. And it can only do one of these things simultaneously. This explains that you can’t be both connected to a Wi-Fi network and sharing that Wi-Fi network’s connection over Wi-Fi. Of course, you may sometimes want to try this out; for instance, when you’re staying in a hotel or other location that only allows you to connect one device to its Wi-Fi network.

In order to share a Wi-Fi network connection by creating another Wi-Fi network, you will need a separate physical network interface, for instance a USB Wi-Fi adapter.

You could also easily create a Bluetooth PAN (Personal Area Network). Then connect it to the Wi-Fi and configure your Mac to share the Wi-Fi connection over a Bluetooth PAN. If other devices you want to share your internet connection to have Bluetooth, you can pair them to the Mac and wirelessly share the Wi-Fi connection over Bluetooth.

Although, a Bluetooth PAN can take a bit longer to connect and can’t reach the speeds of Wi-Fi. However, it is also a bit lighter on your Mac’s battery life, so it’s not bad at all.

Windows OS has a functional feature that allows you to create a virtual Wi-Fi adapter interface, making it possible to both connect to a Wi-Fi network and create a Wi-Fi hotspot using the same physical network interface at the same time without using any software. This feature is likely hidden, but can accessed using the Virtual Router software. The Virtual Router software uses the same Windows features as Connectify, a commercial application.

Macs OS unluckily don’t have identical kind of virtual network interface feature. So to share a Wi-Fi connection over Wi-Fi, you’ll need a separate physical Wi-Fi interface
