We can all agree that connecting a MacBook to a projector has always been better for a bigger secondary display for presentations and entertainment purposes. However, while connecting a projector to a laptop is relatively simple, not every device setup is identical, and issues can always arise.
After making the necessary purchase for all requirements, I wanted to know how to connect my MacBook to a projector. Fortunately, after several trials, I successfully established a connection and used my projector as a secondary screen.
If you have the correct adapters and cables, the connection process will take you no time. However, many people find it difficult to establish a connection because they can’t find the right cable to use. In this article, I’ll explain how to easily identify the right cables and connect your MacBook to a projector.
Identify Your Mac Connectors
Understanding your computer’s ports is key to connecting your MacBook to a projector. Unfortunately, most MacBooks don’t have an in-built HDMI port. Nevertheless, you can still connect with HDMI using a port adapter.

Apple issues user guides for its products to see which ports and adapters you need. Also, You can look at the Apple port symbols guides and shapes or enter your Macbook’s serial number on the Apple Tech Specs page for guidance. Here’s a summary of the types of ports found on Macbook products.
i) HDMI Port
If your Mac has a HDMI port, you can directly connect to a projector with the projector’s HDMI cable without using an adapter. Luckily, most projectors support HDMI input, and the HDMI cord is likely included with the projector.
ii) MiniDisplay Port
This looks similar to a smaller version of an HDMI, and you will likely need an adapter, but your projector may include one.
iii) USB-C or Thunderbolt Port
You can choose any device with a USB-C port on one end and a HDMI port on the other. A new projector may also come with the piece you need because you’ll be able to choose before making a purchase. Notably, many MacBook models mainly have USB-C connectors.
iv) VGA Port
Some older Macs have VGA ports. In that case, you’ll need a VGA connector or VGA adapter to connect to your projector.
a) Connecting a MacBook to a Projector Using Cables
Step 1: Power on Your MacBook and the Projector
The first step is to power on your MacBook and projector. Ensure your computer is charged before using it. Also, you can use it while charging by connecting it to a socket with the approved charger.
As for the projector, plug its power cable into an electric outlet. Additionally, ensure you plug the cable tightly and correctly.
Step 2: Connect the Cables

You can connect your Mac to the projector with any video cable, provided it is compatible. However, if those ports are unavailable, you might still need a suitable Mac adapter cable to connect via the VGA, HDMI, and USB-C ports.
Knowing these ports is essential to understanding how to connect a MacBook to a projector without difficulties.
Here are some common cable connection tips:
- If your projector has a USB-C input, use USB-C to USB-C cable as it is easier and more convenient; plus, MacBooks have multiple USB-C ports.
- If it has an HDMI input, the most common and easy to connect, use an HDMI to HDMI cable or USB C to HDMI cable to create a connection.
- On the other hand, if your projector is old, it may only have VGA input. In this case, you will need an HDMI to VGA adapter or VGA to VGA cable anda USB-C hub.
Step 3: Open the Apple Menu
Once the cables are connected to the correct inputs, some projectors are smart enough to switch to the port you plugged into automatically, but some are not. In the case of the latter, tap on the Apple Icon at the top-left corner of your laptop screen and select System Preferences from the dropdown menu.
Step 4: Select Display Settings
From the System Preferences, select Displays from the dropdown menu. MacBook will automatically detect the projector; if not, restart steps 2 and 3. Alternatively, you can click on Detect Displays on the Display Window to synchronize the two devices.

On the “Use As” option, select Mirror, Main Display or Extended Display from the dropdown menu, depending on your requirements.

With a wireless connection, you might or might not need Wi-Fi casting. This will depend on your projector’s ability to support casting over Wi-Fi. To find out, check the projector’s manual. Alternatively, go to the menu or multiscreen option on the projector and look for anything specifically for Mac devices like Airplay.
