WavTap
Capture whatever your mac is playing to a .wav file on your Desktop—as simply as a screenshot.
(This is alpha software. It will cause your computer to catch fire. 🔥)
Installation
Run the installer.
NB: As of 10.10, OSX now bans drivers that haven't received explicit approval from Apple. The only workaround I'm aware of is to set a system flag to globally allow all unsigned kernel extensions. This means WavTap will not work unless you've enabled kext-dev-mode, using something like this:
sudo nvram boot-args=kext-dev-mode=1Yes, this sucks.
Uninstallation
make uninstall removes everything
