A kernel extension is code that modifies the kernel, When CMU created the
Mach kernel ( a little like the Linux kernel,… ) it provided the ability to add
extensions to extend driver functionality. Apparently Rogue amoeba software
requires this to get to the underlying audio streams. Apple discourages kernel
extensions for the past 4 or 4 versions, since they can have full access to
everything in your computer. But since there are various products that depended
on kernel extensions, Apple provides a way for a user to still allow these
extensions to run.
HTH!
