I think you can objectively say that the number of creative right brained people using Mac OS X are substantially higher than the number of such people forced to use Windows. To not have OS X drivers for your products is far worse that negligence.
You would get very many new faithful customers in the creative industries if you made great OS X drivers, especially in the 3D, graphical and video sections. We are talking tens of thousands here!
It is frankly very surprising that you have not created OS X drivers and even more so considering what users would be attracted to your products. My feeling is that your company is a PC Windows company and that you simply are stuck and not very flexible. Ouch - that must suck big time!
In any case, make your products function on the Mac especially with the following software:
All Adobe software
Final Cut Studio
In fact, all 3D software on the Mac!
The best things would be to develop a general driver app that can be fully customized to work with any Mac OS X application.
If you guys are stuck at this, I know someone who could make that happen - and fast. Get your thumbs out and get going!
