Screen Capture with Audio is impossible on macmini

Yes, you can record audio on your Mac without a microphone. There are at least 2 ways to screen capture video with audio - use a screen capture app or use an audio routing app.

My preferred way is to use an app designed for screen video capture, such as Screenflow. I have it and it works great. I have done amazing captures using Screenflow. And it includes video editing capabilities.

If you want to DIY, then install Blackhole Audio app (free) and use it to configure a "Multi-output device" to route audio to apps such as Quicktime ... in order to capture screen video+audio using QuickTime. See the Blackhole Help pages & Wiki for instructions on how to do this. See this thread for additional tips on using Blackhole audio -> how to record screen with audio on mac mi… - Apple Community

For more robust audio routing, consider Rogue Amoeba's Loopback app.

ps. It's not a hardware issue. Macs have never come with "built-in" streaming video+audio capture.

Hi Ian,

You are correct about using a webcam mic to record audio but it wouldn't be screen audio (as in a streaming lecture or video).

The OP wants to capture the audio from streaming videos, not from a mic. Technically it's called system audio or application audio. Blackhole & Loopback are audio routing apps that enable that to be done with Quicktime. Screenflow is a single app that does it all without needing any routing app.

Thanks for the info Martin.

When I first read the question my first instinct was to shout, "Rubbish!" (or something similar).

However, I desisted and on investigation discovered he was correct.

There is another way to record the screen audio . . . as the mini has not got a webcam, most users will have one clipped to the top of their monitor.

Assuming the computer is playing the audio the webcam mic will pick it up. Quality not as good as the other way but still perfectly OK.

I agree that Screenflow is the best solution which is why I use it.
