screen recording

The most common third party software helper for recording system audio, is SoundFlower. Just google it and you will find several options. There is however an Apple recommended app. which is far better than SoundFlower and it is part of an application made available by Apple in the App. Store. The App. itself is called RecMaster and it is and advanced version of Quicktime Player, a default app. on all Macs. I use it in place of the default QT as it offers greater flexibility. It uses a sound capture device called 'Aunboxsoft Audio Device'. It can be downloaded as a separate app. https://www.recmaster.net/mac-audio-driver-install-guide RecMaster is a paid app. from about $9.99 but the Aunboxsoft Audio Capture Device is free.

I have tried several apps, in place of QT, and find RecMaster to be the best. Aunboxsoft can be used with the default Mac QT.

If you download it and have difficulties in getting it to work, just come back to this post and let me know.

Was the sound being recorded with the built in microphone?

A default QuickTime does not provide means for capturing the system audio, other than speaker to microphone.

• The are third party software components to aid in getting the system audio internally (Soundflower, BlackHole).
• The are complete third party screen capture applications that also fill this gap (e.g. ScreenFlow, Camtasia, Capto).
