Some versions of Mac OS need special system settings to allow a shared memory
segment to be created (this is how the application communicates with the decoder).

Included in this DMG is a sysctl.conf file that you can use to increase the 
shared memory that the operating system allows to be allocated. You only have to do this process once. 

To install:
