I use a Mac and no longer use the efax service. However, nearly every time I use my computer, an annoying pop-up "efax messenger for Mac" window.
I have tried everything to get the application off my computer. I have called efax technical support a number of times. I spoke with several English speaking technical support reps who told me they do not know how to remove the program from a Mac, only from a PC. Other times I've called, I've gotten transferred to tech reps in India. I have been instructed to call a Mac specialist to remove the program. Shameful.
