Mac OS X booting up in single-user mode. In PowerPC-based Macintoshes, the boot process starts with the activation of BootROM, the basic Macintosh ROM, which performs a Power On Self Test to test hardware essential to startup. [4] On the passing of this test, the startup chime is played and control of the computer is passed to OpenFirmware.
A Happy Mac is the normal bootup (startup) icon of an Apple Macintosh computer running older versions of the Mac operating system. It was designed by Susan Kare in the 1980s, drawing inspiration from the design of the Compact Macintosh series and from the Batman character Two-Face . [ 10 ]
Here is a simplified view of the Mac OS X Tiger system startup on a PowerPC Mac (on an Intel Mac, EFI replaces Open Firmware and boot.efi replaces BootX): Open Firmware activates, initializes the hardware, and then loads BootX. BootX loads the kernel, spins the pinwheel cursor, and loads any needed kernel extensions (kexts). The kernel loads ...
The Apple–Intel architecture, or Mactel, is an unofficial name used for Macintosh personal computers developed and manufactured by Apple Inc. that use Intel x86 processors, [not verified in body] rather than the PowerPC and Motorola 68000 ("68k") series processors used in their predecessors or the ARM-based Apple silicon SoCs used in their successors.

A modern PC is configured to attempt to boot from various devices in a certain order. If a computer is not booting from the device desired, such as the floppy drive, the user may have to enter the BIOS Setup function by pressing a special key when the computer is first turned on (such as Delete, F1, F2, F10 or F12), and then changing the boot order.

However, the installation of OS X on an Intel-based Mac demands a GPT partitioned disk or will refuse to continue, the same way installation on a PowerPC-based system will demand an APM partitioned destination volume. Cloning an already installed OS X to an APM partition on Intel systems will remain bootable even on 2011 Intel-based Macs ...
This method allows users to conduct the Leopard-based OSx86 installation using a stock, retail-purchased copy of Mac OS X Leopard and eradicates the necessity of a hacked installation like JaS or Kalyway (mentioned previously). The Boot-132 bootloader essentially preloads an environment on the system from which Leopard can boot and operate.
The concept of a universal binary originated with "Multi-Architecture Binaries" in NeXTSTEP, the main architectural foundation of Mac OS X.NeXTSTEP supports universal binaries so that one executable image can run on multiple architectures, including Motorola's m68k, Intel's x86, Sun Microsystems's SPARC, and Hewlett-Packard's PA-RISC.
