Q: The MixWizard 4 Mac Driver V3.2.2 (July 2014) says OSX 10.11 El Capitan is supported, but the installer won't run.

A: There is a known issue with the WIZARD 4_3.2.2 installer package and it does not open normally in El Capitan by double-clicking or using right-click > Open.

cmd+click on the package and select 'view package contents', navigate to the '105' folder, double click the .pkg file inside the folder to install.

The installer will now run normally and is fully supported.
