I want to explain that almost all Windows users who begin to use OsX have difficulties to distinguish a topic I've seen. 

When you enter OsX world the name you will see frequently mentioned suc as Natit, NVinject, Titan, ALCinject services are not drivers, these tools are called the injector or enabler. To install these tools does not provide the system (video card, sound card, etc..) to study on its own.

To understand what the injector is, why the injector is needed, it is required to grasp hardware identification system of OsX. Macintosh in a genuine device, before starting osx, by working the startup firmware which is the last part of efi define the hardware and writes ram of the system by creating a list of "Device Tree" in order osx to use. (for the device tree with a rough Turkish we could say "equipment list", this list includes detailed specifications of all hardware on the machine)

After the OsX starts, the kernel is engaged and it installs required drivers for the hardware’s by using device tree. Because of standard PCs we are using benefits from efi instead of bios as a landing management system, when the kernel of OsX is engaged, it finds a page as clean and blank as my heart in device tree. However because of it could not reach the list of hardware, although there are suitable drivers in the extensions folder, opens the system before the hardware is recognized by not installing any drivers

Here the injectors come into play, for which type of hardware the injector was written for adds required information to device tree for that device. (e.g. natit for the video card; alcinject for the sound card do this) When OsX kernel looks device tree, because of it could find related hardware on the list correctly by installing the necessary drivers, it allows the hardware to work functionally. 

As a result in order to make a hardware to be able to work correctly by OsX at first injector and then the driver of the related hardware are needed. Injector’s without the drivers inside OsX of hardware’s are no useless.
