...It focuses only on unsupported 82357 GPIB adapter but can be extended to other USB boards if there is a need for that in the future.
The code is mainly based on linux-gpib and includes also code from fxload for mac project.
This project generates a dynamic library which can be linked against any kind of application which support dylib.
It also comes with a python wrapper.
macosx_gpib_lib is not a kernel extension and only supports 82357x adapter for now. It has been designed for 64bits architecture but the target is 10.6.
The performance is not as good as linux-gpib is as this library uses Cocoa and not low level functions.
