I'm trying to record both what's happening on screen and the audio being played by the applications. To my surprise, QuickTime did not record the sound. I believe it worked before in previous OS X releases, but that is not something that I use often so I have not bothered to try earlier.

What is the current situation on El Capitan ? Have I messed with something that prevents QuickTime from capturing the sound, or has it never worked ?

Here is my view of Quick Time / New Screen Recording on a Mac Mini: enter image description here

On my Macbook Pro, I have the option select None or Internal Microphone. Internal microphone actually records the speakers of the Mac Book as heard from its own microphone, which obviously sounds terrible.

This is a MacMini 7,1 (late 2014) and there is nothing in Input Sources.

    If your MacBook Pro has USB-C connectors, there is a way to force them into analog audio mode where you can pipe analog audio out back into the microphone input. Check en.wikipedia.org/wiki/USB-C#Audio_Adapter_Accessory_Mode_2

  • This works even if you have an older MacBook (El Capitan) and/or only have one audio port on your computer.

You need to install Soundflower in order to run it on El Capitan. El Capitan requires kext to be signed in order to load them. This one gets its kext installed in /Library/Extensions/.

This is due to System Integrity Protection

Then, you have to create a multi-output device with: Audio MIDI Setup.app, which is found in /Applications/Utilities/ :

enter image description here

Finally, when you want to do the actual recording, make sure you use this multi-output device, and capture from the same Soundflower device used in this multi-output device. Otherwise, you can't both listen to and capture the sound, because it goes directly to soundflower without being copied to the built-in output.

alt/option + right clicking on volume gives you this menu:

and Quicktime now looks like this:

Use Background Music.

To install, either:

  1. brew install --cask background-music

  2. Or go to https://github.com/kyleneideck/BackgroundMusic and install the .pkg file.

Now, in Quicktime Screen Recording, you will see an option for Microphone for "Background Music". Select "Background Music". Then when you do the screen recording, it will record the System Audio.

For those wanting to record their voice or the sounds coming from the speakers...

No extra software is required.

You just need to click the little arrow to the right of the record button and change it from None to Internal Microphone.

Not sure why this is defaulted to None but I was caught by surprise when I changed from an old Macbook to a new one with a fresh OS install.

Although it's not an ideal answer to the OP's desires, I'm leaving this answer here because it answers the question in the title.

    The question is about the ability to record sound, not which particular microphone you use. The important thing is to use that arrow to switch from None to whatever microphone you like - no extra software required.

Of course you can use QuickTime to record both screen with audio, and you need to install a virtual sound card like soundflower to capture computer sound. Besides, you can also try to use screen recorders like ShowMore (free screen recorder for Windows and Mac), Jing (5 minutes' recording limitation) and many more to do the recording.


For those who aren't finding Soundflower in the AppStore, tracking down the correct downloads for this semi-dead project can be kind of tricky.

I installed the Kernel Extension from here: https://github.com/mattingalls/Soundflower/releases (Note that to follow the instructions for Audio MIDI Setup, I Had to choose Window > Audio Setup)

Then I installed SoundFlowerBed from this fork: https://github.com/mLupine/SoundflowerBed/releases

That puts an item in the menu that allows you to set SoundFlower (2ch) --> Built-In Output, which then makes "SoundFlower" available in QuickTime Player etc.


Don't bother with installing software or extensions.

You just need an "aux cable" (which has stereo 3.5mm headphone plug, male at both ends). Any length will do.

enter image description here

Plug one end into the headphone jack and the other end into the mic jack.

If your system doesn't have a mic jack, you can use any USB-to-audio input device you please; most automatically recognize on the Mac.

  • @webtweakers You can use headphone to USB if you get an USB-adapter with aux. Or if you wanna be superfancy, the headphone jack actually supports sound in on most Macs, build your own AUX that loops the sound! I have never seen any such device but nothing is impossible.

  • Most Macs have a single audio 1/8" that is both the Mic input and Headphone output, so this can't be done as-is without extra hardware. Some Headphone/Mic splitters are listed here: mac-forums.com/threads/…

I started using Voila-->Capto. Costs money but works well and even has a feature to stop recording after a set time and other features.



For everyone arriving here from a google search in 2020 with Catalina, trying to record from the internal microphone without success...go to Preferences -> Security & Privacy -> Privacy tab -> Microphone and make sure QuickTime Player is checked.

  • Thanks. I ended up using Screenflick which worked pretty well.

You can also use SoundFlower for this. In a way, it acts like a microphone, which makes it possible to select it as an audio source in Quicktime.


If you want to record the audio generated by your running applications etc. you will need to use SoundFlower or something similar. It's available free from the AppStore.
If your internal microphone is glitching out and you just want the system to recognise the hardwares presence again; try simply plugging some headphones or something into your 3.5mm TRRS audio jack.
I had the same problem the other day and thought the actual soundcard was fried but just making that quick contact brought it straight back online.

    @Flimm Soundflower is solid. cycling74.com was the original developer and they are good at what they do. They are probably busy with their commercial products (i.e. Max) so don't officially support it anymore and Soundflower is unlikely to have its own website anytime soon.. However, the main author Matt Ingalls is currently hosting the project at github.com/mattingalls/Soundflower if you don't want to use the App Store.

To screen record WITH internal audio AND microphone voice over using QuickTime on a Mac (without downloading additional software) you will need a USB microphone and a Bluetooth headset + mic'd audio cable. This works even if you only have one audio port on your computer.

  1. Plug the USB mic into the computer.
  2. Plug the audio cable into the computer.
  3. And the other end of the audio cable into the microphone.
  4. Open System Preferences, set the Sound Output to USB, and Input to the Microphone port.

To listen through the headset while you screen record, there are a few more steps.

  1. Connect the Bluetooth headset.
  2. Open Audio MIDI Setup (Applications > Utilities), and create a Multi-Output Device, adding the headset with Built-in Output.
  3. Go back to System Preferences and change the Sound Output to the new Multi-Output Device.
  4. Open QuickTime to create a "New Screen Recording" setting the microphone option to Built-in.
