As of Painter 2020 Update 1, the Mac installer will no longer be including the driver that allows artists to select the “Soundflower” option which captures “internal audio” for Audio Expression Brushes.

Artists that wish to continue using internal audio on their Macs for Audio Expression can choose to install a similar driver manually via this link:
