Screencast with VoiceOver
Here’s a quick how-to on recording your Mac desktop while using the VoiceOver screen reader. With this setup you’ll be able to capture both video and internal audio at the same time, and hear the audio output while recording.
For this setup we’ll be on OS X El Capitan and use QuickTime to capture the video and audio. The only extra thing required is the iShowU Audio Capture driver.
