First a report and explanation from Alain.
One of the problem faced by Mac OS X in industrial environment is the lack of specific drivers required to control or manage different types of electronic devices, especially VME.One of my colleagues developed a VME driver for Mac OS X and has been using it successfully for several month in a complex scientific and industrial environment (nuclear center). It offers ease of use and reliability, something not reached with similar solutions running on Windows or other systems. This work has been supported by Apple via its ARTS program.
The following driver is available: A Mac OS X universal binary kernel driver for SBS (previously called BIT3) 618, 620 VME controller+PCI card with optical links: http://www.ill.eu/computing/cs-software/all-software/vme-driver-for-mac-os-x/
