Want to record screen with sound on Mac?

Download the installation file, double-click it, and follow the instructions on the screen.

On the Screen Recorder control panel on the right, click the Screen recording button. Select the recording area: frame it using your cursor, click on the window to frame it, or click outside all windows to record the whole screen. Make sure the colored frame has appeared.

If you want to record video with sound, check the System Audio button. When it is displayed in green, sound will be recorded, so if the button is gray, just click it. If you want to add your voice or other external sounds, click the Microphone button, and this will appear in green too. Click on Start recording to begin.

There will be a 3-second countdown. You can control the process of recording using the Pause and Stop buttons. After you click Stop, the preview window will appear.

In this window, you can trim the unwanted parts of the video clip: for each of these parts, place the position marker at the beginning and click Cut, then move the marker to the end of the segment and hit Cut again. Select the unneeded section with the marker and click Delete fragment. Repeat for all the segments you want to get rid of. When you like the resulting video, click Export.

Choose an output format from the Format list, and click Save. You’re done!
