Quicktime No Sound Recording Screen on MAC
If you are having problems recording your screen using Quicktime on a Mac, then this video may be able to resolve your problem. Click the screen recording option, then be sure to use the drop down arrow to select the microphone you would like to use. If you are still not getting sound, then it could be that you need to turn up your input volume. If that does not work, then it could be that you need to reset your ports by calling Apple Care. Hope this helps.
