Seamless Apple TV iPad Mirroring 1 of 3: Create a MacBook WiFi Hotspot

Is slow or no WiFi in your presentation room slowing you down?

Seamless Apple TV and iPad Mirroring 1 of 2 | Create a MacBook WiFi Hotspot

Every presenter has been in the situation where they are stoked to try some new tech when delivering a workshop. Quite a bit of research, learning, and preparation has been invested into your presentation over the days or weeks prior. As you’re getting ready to “wow” your attendees with your innovative idea, you realize there is no WiFi signal in the conference room or such a weak signal that it is completely useless. Or, perhaps you’ve spent ages on how to choose the right TV, and have set up a comfy home studio to watch a show with your family, only to find yourself facing this same issue.

This situation doesn’t just happen to conference workshop presenters as it can also happen in the classroom. It takes quite a bit of resiliency and confidence in both the technology and subject area for a teacher to try new technology in the classroom. So much can go right, but so much more can go wrong.

If you plan on using an Apple TV, Reflector, or AirServer to mirror your iPad screen, it is always good to have alternative options available to you when things don’t go as planned. Creating a WiFi Hotspot with your MacBook is a great way to get around a WiFi Network that is having trouble. Creating a MacBook Hotspot can be done as an “ad hoc” network (i.e.: without internet access available) or as an Internet Sharing Network.


If you are a teacher, please note that you should contact your IT Department prior to creating your own network to ensure that you are not violating any IT policies in your district. They could also help with tech support, be it with the IP setup or other matters.

At my board, the Greater Essex County District School Board, personal devices (including routers or computers) cannot be wired to any GECDSB Ethernet Drop.

Unsure if you’re breaking the rules? You should contact your IT Department.

How to Create a MacBook WiFi Hotspot in Minutes

The Step-by-Step Guide With Screenshots:

Step 1 – Connect MacBook to a Hardwire Internet Connection

Connect your MacBook Pro, MacBook Air, or similar to a hardwire Internet connection. Newer MacBook Pro Retina requires a Thunderbolt to Ethernet dongle to connect the Ethernet cable to the Macbook. Attach the other end to your Internet router or Internet drop. Alternatively, there are numerous broadband deals that would let you connect the laptop to the internet wirelessly.

Again, ensure you are not breaking IT Policies by connecting your ethernet cable to an internet drop.

Step 2 – Access Network Settings

Go to System Preferences -> Network and ensure the MacBook is receiving an Internet connection from the Ethernet port / Thunderbolt port (depending on your MacBook). You will need to identify where the Internet connection is coming from later.

Step 2 - Determine Which Thunderbolt Port Ethernet is Using

Step 3 – Access Sharing Settings

Go to System Preferences -> Sharing and configure the Internet Sharing settings. Ensure that the Internet Sharing checkbox is unchecked in order to configure.

Use the pull-down menu next to Share your connection from: in order to select where the Internet connection is coming from. It will likely be Ethernet, Thunderbolt Ethernet, or USB Ethernet, depending on your MacBook and configuration.

Where it asks To computers using:, select Wi-Fi.

Step 3 - Access Sharing Settings and Configure Sharing Settings

Step 4 – Configure Wi-Fi Options…

While still in the Sharing Settings screen, click the Wi-Fi Options… button at the bottom right. Here, you can name your MacBook Hotspot Network for your classroom and set a password.
