How to Chromecast from a Mac computer

Once you plug your Chromecast into the HDMI-capable television or projector of your choice, you need to set up the device by downloading Google Home on either your smartphone or tablet and following the instructions to set up the device.

You’ll also want to download the Google Chrome web browser. It is called "Chromecast" for a reason, after all.

From there, click the three dots in the right hand side of the browser and click the "Cast" button.

Then, keep the Chromecast icon in your toolbar by selecting "Always show icon."

How to Chromecast streaming services

Casting from most streaming video sites – Netflix, Hulu, Amazon, etc. – is simple.

Just click the Cast button, select your chromecast, and Chromecast should stream to the device of your choice.

Otherwise, you can also click the Chromecast icon that will show up in the corner of Chromecast-compatible websites like Netflix and YouTube. Either works just as well.

How to Chromecast your Mac’s desktop or any Google Chrome tab

If a streaming site isn’t natively Chrome-compatible – or you just want to cast the contents of your Chrome tab, it’s as simple as selecting the drop-down arrow from the "Cast to" dialogue box.

It will then turn into a "Select source" dialogue with options for what you can cast.

Likewise, you can easily cast your desktop contents. This makes the Chromecast a superb device for presentations. No more worrying about long cords to a projector or other dongles – a Wi-Fi connection will do the trick.

How to Chromecast local video and audio files

Because Chromecast is usually thought of more as a device for playing content from tablets or phones, the fact it can play local video and audio files from your computer is often overlooked.

Select "play local content" from the dropdown and select either an audio file (MP3) or video file (MP4, MPG, and M4V files, among others). The content will launch in a Chrome tab and cast from there.
