Airflow 3.3.10 — macOS

You have a video file on your Mac that you want to watch on the big screen. Airflow gets it to your Chromecast in a couple of clicks. Drag the file into the app, pick your Chromecast device, and playback starts. No conversion, no extra steps.

Stream video files to a Chromecast with drag-and-drop

• Streaming video files stored on your Mac to a Chromecast
• Quick drag-and-drop playback without opening a browser
• Using a simple interface that gets out of your way

Requires macOS 10.12, Intel Mac, and same network as Chromecast

• Requires macOS 10.12 or later and Intel architecture
• You need a Chromecast on the same network
• Only English interface language

Confirm your Mac and Chromecast are on the same Wi-Fi

Once Airflow is in your Applications folder, take a minute to confirm your Mac and Chromecast are on the same Wi-Fi network. The app scans the local network for devices, so if you don't see your Chromecast listed, that's the first place to check. Open the app, drag a short video file into the window, and select your device. If playback starts, you're set.

I usually test with a common format like an MP4 file during the first run. That way, if anything needs adjusting, I know it early. The interface stays minimal — a list of available devices and the video you dropped in. No settings panels to dig through.

Troubleshoot when your Chromecast does not appear in the scan

Chromecast not showing up in the device list

This is the most frequent hiccup. Make sure your Mac and Chromecast are on the same network. If they are, check that your Mac's firewall isn't blocking local discovery. A quick restart of both the Mac and the Chromecast often resolves it. If you're on a corporate or guest network, the Chromecast may not appear because those networks sometimes isolate devices from each other.

Video plays but has no sound

Some video files use audio codecs that Chromecast doesn't support natively. Try a file with AAC or MP3 audio to see if that works. Airflow streams the file as-is, so the source file's format matters.

App won't open after dragging to Applications

Because Airflow requires a Gatekeeper bypass via Terminal, you might see a message that the app can't be opened. If that happens, open Terminal again and run the command you used during installation. On macOS 10.12 and later, Gatekeeper settings can vary. If you're on a newer macOS version, you may need to allow the app in System Preferences under Security & Privacy before it will launch.

Airflow quits unexpectedly during playback

This is uncommon but can happen with very large files or unusual container formats. Try a shorter or more standard file first. If the app closes repeatedly, restart your Mac and try again.

Lightweight 64-bit Intel app with minimal disk footprint

Airflow 3.3.10 runs on macOS 10.12 or later and is built for 64-bit Intel Macs. The app itself is lightweight — the disk image is small and the installed app takes up minimal space. Because it streams video to a Chromecast, your Mac does the work of sending the file across the network, not rendering it on screen. You can continue using your Mac normally while playback runs on the TV.

The interface is in English only. There are no configuration panels, codec pickers, or transcoding options. You select a device, drop a file, and playback starts. That's the whole workflow. If you're used to apps that transcode or re-encode on the fly, Airflow is simpler by design.

Best for anyone who watches local video on a TV via Chromecast

Airflow makes sense for anyone who regularly watches local video files on a TV and already has a Chromecast. That includes people who download movies or shows to their Mac, those who archive personal video footage, or anyone who wants a quick way to show a video to a group without passing a laptop around.

It's also useful for Mac users who avoid browser-based casting because of the extra clicks and tabs involved. Drag and drop is faster than opening Chrome, navigating to a file, and waiting for the browser to load it. If you're on an Intel Mac running macOS 10.12 or later, Airflow works as a straightforward utility without extra overhead.

For people who work with video files regularly — editors, archivists, anyone previewing footage — Airflow lets you check playback on a larger display quickly. And if you run a mixed household with Apple TV and Chromecast, it fills the gap for the Chromecast side without needing to switch apps or buy additional hardware.
