Otherwise, go to step 2.

Menu. Click the triangle next to Production Information, and

Mac OS X Alert: Due to technical issues that arise from
the operation of the latest G4 processors (used on this
Encore/MDX G4 Duet card) in an older system, you must use
Mac OS X Version 10.3.5 or later to ensure compatibility; earlier
versions of Mac OS X lack the proper processor support.
