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.


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:

    where do I alt/option + right clicking on volume ? – bernie2436 Aug 1 '16 at 14:00

    When I do this only the computer output is on the recordings, and not the mic. Is there a way to get them both on the recording? – Pablote Aug 25 '16 at 16:31

    Make sure the volume on Quicktime is down to zero, otherwise you'll hear reverberations in your audio recording – jetlej Oct 15 '16 at 13:41

    @bernie2436 if you don't see the Volume item on the menu bar, you can use System Preferences -> Sound -> Output tab and select the Multi-Output device – Aswin Kumar Dec 14 '16 at 10:59

    I'm having the same issue as @Pablote where only the computer's output, not my microphone output, is being recognized. – s2t2 Feb 14 '17 at 18:00

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.

    a.k.a Analog hole.. You will also record your cat and kids crying. Nothing wrong with that but it's just not optimal.. – alecail Dec 7 '16 at 16:33

    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. – nevster Dec 8 '16 at 0:55

    OP's question says he already used Internal Microphone before. – Omega Jan 19 '17 at 5:34

    Ah - I see. I was blinded by why I originally searched for this question in the first place - I wanted to record my own voice. I can see now what the OP is asking. I've edited my answer. (I think it's still worth having here rather than deleting.) – nevster Jan 19 '17 at 9:47

    Thanks - worked great on OS X El Captain – Anupam Jun 30 '19 at 0:06

When you are in the recording screen window, at the right of the red button you must see an arrow, click on it and you should see the audio input dialog. Tested now with OS X 10.11.1

    Can you please specify which is your Mac Mini model? Is the audio Line-in port present at System Preferences-> Sound-> Input? – TuTTe Oct 26 '15 at 22:02

    no such option at macOS: 10.13.3 model: MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports) – Lukas Liesis Mar 13 '18 at 19:21

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.

    This question was specifically for Mac and my Macbook pro doesn't seem to have a mic jack. I have used this very trick on a PC successfully, but needed something else for my Macbook. – webtweakers Jun 25 '16 at 17:00

    This was very helpful for me and my early 2011 MacBook Pro. Thanks! – nrubin29 Jan 5 '17 at 1:12

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.



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.

    Soundflower is not usable on El Capitan because of kext signing. Can you name the alternative softwares on the App Store ? – alecail Oct 28 '15 at 5:30

    What is kext signing? I'm unaware of any alternatives. – voices Oct 28 '15 at 20:14

    I'm hesitant to install Soundflower because it's so old, and the newer forks on GitHub don't seem to have an official website yet. – Flimm Nov 30 '15 at 9:44

    @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. – voices Dec 4 '15 at 17:59
