Introduction Apple's adoption of open standards and support for standard peripheral families yields opportunities for both hardware and device-driver developers. • Hardware developers can take advantage of standard high-performance interfaces to develop add-on or peripheral products that extend the capabilities of the Macintosh. • Driver developers can use the I/O Kit, Apple's object-oriented driver-development framework, to create in-kernel or application-level drivers for their own or another vendor's devices.

In addition, OS X provides several services that allow applications to communicate with hardware from plug-ins, shared libraries, and other code running outside the kernel. Start Here To write code that controls a hardware device in OS X, you should: • Decide whether your code should be in the kernel or in user space. In OS X, many drivers can be written in user space. Network kernel extensions and file systems generally must be in the kernel.

• If you determine that you can write your code in user space, create matching dictionaries to match the appropriate device, then open the device. • If you determine that you must write a kernel-mode driver, determine what I/O Kit class your driver should subclass and what nubs your driver should publish (if applicable). Also create a set of matching rules to tell the kextd daemon when to load your kernel extension and create a property list file that reflects this. • Start writing code that communicates with the hardware. To develop hardware devices for the Mac, read the relevant developer notes.
