Why does Soundflower installation failed on Mac?

Note: We recommend installing BlackHole rather than Soundflower. BlackHole works the same as Soundflower but easier to install. After installation, we recommend using Filmage Screen to record system sound!


Soundflower is a system extension that lets you channel audio from one application to another. While for Mac users, they will always be informed of an error message " The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance." It is because of Apple Provicy Policy which only valifies and allows identified developer's softwares to be installed.

Please download Soundflower from our website.
