1. In order to record both screen and audio on Mac computers, you will need to install Soundflower, first. To do so, simply visit this GitHub link, and click on the “Soundflower-2.0b2.dmg” link to download the installer for Soundflower.
2. QuickTime creates no-audio recording is a normal phenomenon, because as is mentioned above, QuickTime doesn’t feature capturing screen with the sound coming from computer.

Mac OSX has QuickTime Player built-in. QuickTime allows you to easily do a screen recording. However, when doing so, you only get the screen – no audio.

You can install Soundflower to route your computer’s audio back into QuickTime to record it.

Adding Audio from your Computer

This allows you to capture the audio from your computer in your QuickTime screen recording. This is what I kept finding when trying to search for a solution. Google “Screen recording with audio on Mac” and you will see. This option routes ALL audio through Soundflower and therefore you CANNOT HEAR IT to monitor it as it is being recorded.

• Download and install Soundflower http://cycling74.com/products/soundflower/
• Go into System Preferences – Sound – Output — choose Soundflower 2ch
• Open QuickTime
• Start New Screen Recording – Click drop down arrow on right side of dialog box – choose Soundflower 2ch

Screen Record On Mac With No Sound

The Holy Grail (Adding Audio from your Microphone and your Computer while being able to hear the audio as it records)

This is great for a screen-sharing session where you are talking to someone and walking through an application over the computer. This was the exact thing I needed to do when I figured this out, thought I would write it up to remember in the future.

NOTE: If you do not want to include your microphone audio and only include the audio from your computer in your screen recording, just take out the steps related to the “Aggregate Device” and choose SoundFlower 2ch in QuickTime for your screen recording.

• Download and install Soundflower http://cycling74.com/products/soundflower/
• Go to Applications – Utilities — Open Audio Midi Setup
• Click the (+) Plus sign in bottom left corner
• Choose “Create Aggregate Device”
• Place a checkmark next to Soundflower 2ch and Built-in Microphone
• Click the (+) Plus sign again
• Choose “Create Multi-Output Device”
• Place a checkmark next to SoundFlower 2ch and Built-in Output
• Go into System Preferences – Sound – Output — choose Multi-Output Device
• Now, when you open up QuickTime – Start New Screen Recording and select “Aggregate Device” from drop down arrow on the right.

Voila!
