Final answer:
Mac OS X depends on proprietary firmware, a boot loader, and a boot sequence to boot up a Mac computer. This process is tailored specifically for Apple's hardware architecture.
Step-by-step explanation:
The Mac OS X operating system relies on a series of components to function properly. Among these, proprietary firmware, a boot loader, and a boot sequence are key to starting up a Mac computer.
This process involves the Mac's unique firmware, which is not a traditional BIOS like most PCs, but a system designed specifically for Apple's hardware. Once powered on, the boot loader is then accessed to initiate the OS X's boot sequence which loads the operating system into memory for use.
