Plugin directory under Mac OS

Hi!

Does anyone know how I can figure out where the filter plugin directory is under Mac OS? (Under Windows it's in the registry - that works fine)

Or being able to access resources inside the plugin bundle would also suffice.

CFBundleGetMainBundle() returns the Photoshop bundle. Unfortunatelly I don't think getting its path and appending Plug-Ins/Filters is good enough, because I suspect this can differ with the different localized versions of Photoshop.

Thanks in advance,

Kornel
