That may be true for the HDD, but Apple uses tons of third-party components elsewhere. Large parts of their OpenGL drivers, for example, are written by the manufacturers themselves, which is part of the reason why Apple has by far the worst OpenGL support in the industry, and why Metal on desktop is inferior to Direct3D and Vulkan.
