With the release of El Capitan, it has become necessary to upgrade Soundflower for users of iShowU and iShowU HD/HD Pro. Note: This is not necessary for users of iShowU Studio, since Studio has it's own driver which already meets the new requirements.

Click Continue when the OS X installer comes up. It will ask to select Agree or Disagree few times. Click on Agree or Continue on all selections. When the installing process is done, you need to configure settings.

Go back up to the Install Clover on Your USB Drive section and follow the steps again, but this time, select your El Capitan volume instead of the USB drive.

Upgrade from previous versions to OS X 10.11 (El Capitan)

  1. From the Apple menu, select App Store....
