Cannot Record Microphone Audio With Camtasia 2021.0.9 on macOS

Problem

When recording both microphone and system audio only one audio track appears on the timeline and the mic audio is missing.

Solution

This is a known issue with version 2021.0.9 that we hope to fix in a future release. For now please exit Camtasia and install the previous version from here. If asked to Keep Both or Replace please select Replace to overwrite version 2021.0.9.
