Thanks Changing the char** to a string buffer (char*[]) solved and then using copyinstr solved the problem. I am curious Aren't GetProperty()/SetProperty() for only for for modifying registry entries? --- Marek Kozubal <marek@portents.com> wrote:

I just realized, that I should have mentioned this

is for kext's that are

not IOKit kext's. If you're in IOKit you use

GetProperty()/SetProperty()

type methods.
