How to Record Internal Audio Only of My MacBook While Screen Recording?

I use QuickTime to record movies on my MacBook, but I found that there is no audio expect my own voice. What's wrong with it? Can you tell me how to record only internal audio of my MacBook while screen recording? Thanks!

The reason why your QuickTime only captures your voice is that it only supports recording audio from the microphone while recording your Mac screen. If you want to capture the system (internal) sound, you need to install a plugin called Soundflower, which will help capture the internal audio of your MacBook.

However, I find it is too complicated to use QuickTime and Soundflower to record a Mac screen with internal audio, as you need to ensure every step is correct. Given that, I suggest you try a professional Mac screen and audio recorder, like EaseUS RecExperts.

This professional Mac screen recorder supports recording both internal and microphone audio from your Mac device without additional plugins. Besides, it offers better video recording quality; for instance, you can use it to record up to 4K on Mac screens and even higher. What's more, it is extremely easy to use, and any level of users can handle it with no hassle!

Now, let's check how to record a Mac screen with only internal audio:

Step 1. Launch this tool on your Mac and choose the recording area based on your needs.

Step 2. Select the system audio as the audio source at the bottom of the main interface.

Step 3. Once done, click REC to start your recording.
