There is no difference between the files with respect to Poser.  The hard part is installing content into the Runtime without overwriting existing folders on MacOS (as it replaces folder contents whereas Windows merges folder contents).  DittoGUI is good for this - Daz3D has MacOS installers otherwise.

I've literally copied (carefully with the caveat mentioned) Runtimes on my Windows system to my Mac system and everything works.  There is no real need for conversion.

Now, there are some issues with Poser 4/ProPack and earlier in regards to Windows and MacOS - but using Poser 7 in MacOSX you should not worry about this.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
