First

• I do not have access to a MAC.
• I have never owned a MAC.
• Ihave never used a MAC
  
• A MAC owner voluteered his services and these are the problems.
  

Second

• There are major differences between Premiere Pro CS4 for Windows and for Macintosh with OS X  in what effects are available, available features like the film count down leader and most significantly:
• It does not have the capability to export the Timeline as an AVI file.  This is the heart of the disk intensive testing in all the PPBM benchmarks.
• It also would require a rewrite of the data collection script from the current Microsoft Visual Basic Script language to (probably) a Java based script and since I am heavy on hardware and extremely weak on writing scripts would be another major complication.

All that said I have received results from the previous PPBM+ version on a MAC running the Windows version
