When I was running Mac OS X El Capitan, I saw we could free record our screen and upload it to YouTube for sharing or put it into PowerPoint or Keynote presentation. However, there was no sound. In the most recent macOS update, Mojave, I see it is quite easy to free record your screen with sound now and in this tutorial, I will show you how to free record screen with system sound in detail on macOS Mojave using Quicktime.
Use Quicktime Player for Free Recording
Go Applications, and open QuickTime Player.app. Go click File on the top and then New Screen Recording or use the keyboard combination COMMAND+CONTROL+N for a new screen recording:
Click the little arrow(drop-down menu) on the side of the red record button and make sure the Internal Microphone is selected under the microphone section.
Click the red record button to free record video and system audio on Mojave. Followed is an overlay that reads: “Click to record the full screen. Drag to record part of the screen. End recording by clicking the stop button in the menu bar.” teaching you how to record full screen or part of the screen.
Click the stop button in the Menu bar to stop recording. The stop button is on the top-right:
If the recording meets your needs like sharing on YouTube or presenting in PPT, click File menu in QuickTime and then choose Save or use COMMAND+S to save the MOV file to wherever you need.
Soundflower is a Mac extension that allows programs to pass audio to other applications. Using this program you will be able to record system sound with along with the video as well. The latest soundflower is 2.0b2 and it signed to meet Apple’s new code-signing requirements and will be installed in the /Library/Extensions folder as required.
Convert/Burn/Edit Recorded MOV File
As we can see, the saved file for QuickTime recording is MOV, the most Apple compatible video format. If you want to convert, edit or even burn the MOV file, I’d like to recommend an all-in-one video solution-Wondershare Video Converter Ultimate.
Wondershare Video Converter Ultimate is the all-in-one solution to convert, edit and even burn MOV files. You are able to convert the MOV file to whatever video formats like AVI, MP4, VOB etc and you can add the MOV for burning to DVDs.
