Early MacBook and MacBook Pro computers used an internal variant of USB as a keyboard and trackpad interconnect. Intel-based Mac doesn't use standard TPM. It also plays a part in the protection scheme deployed to restrict booting macOS to Apple hardware (see Digital Rights Management below).

The first non-beta version of Boot Camp is included in Mac OS X v10.5, "Leopard." Before the introduction of Boot Camp, which provides most hardware drivers for Windows XP, drivers for XP were difficult to find. On April 5, 2006, Apple made available for download a public beta version of Boot Camp, a collection of technologies that allows users of Intel-based Macs to boot Windows XP Service Pack 2. Many operating systems, such as earlier versions of Windows and Linux, could only be booted in BIOS mode, or were more easily booted or perform better when booted in BIOS mode, and thus USB booting on Intel-based Macs was for a time largely limited to Mac OS X, which can easily be booted via EFI.

Legacy Live USBs cannot be used on Intel Macs the EFI firmware can recognize and boot from USB drives, but it can only do this in EFI mode–when the firmware switches to BIOS mode, it no longer recognizes USB drives, due to lack of a BIOS-mode USB driver. For multibooting, holding down "Option" gives a choice of bootable devices, while the rEFInd bootloader is commonly used for added configurability. Intel Macs can boot in two ways: directly via EFI, or in a "legacy" BIOS compatibility mode. The GPT replaces the Master Boot Record (MBR) used with BIOS.īooting To Mac operating systems It is a part of the Extensible Firmware Interface (EFI) standard proposed by Intel as a substitute for the earlier PC BIOS. GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk.

Since many operating systems, such as Windows XP and many versions of Windows Vista, are incompatible with EFI, Apple released a firmware upgrade with a Compatibility Support Module that provides a subset of traditional BIOS support with its Boot Camp product. Designed by Intel, it was chosen by Apple to replace Open Firmware, used on PowerPC architectures. Extensible Firmware Interface (EFI) is the firmware-based replacement for the PC BIOS from Intel. With the change in architecture, a change in firmware became necessary. Main articles: Extensible Firmware Interface and GUID Partition Table With the change in processor architecture to x86, Macs gained the ability to boot into x86-native operating systems (such as Microsoft Windows), while Intel VT-x brought near- native virtualization with Mac OS X as the host OS.

With the change in architecture, a change in firmware became necessary Apple selected the Intel-designed Extensible Firmware Interface (EFI) as its comparable component to the Open Firmware used on its PowerPC architectures, and as the firmware-based replacement for the PC BIOS from Intel. that use Intel x86 processors, rather than the PowerPC and Motorola 68000 ("68k") series processors used in their predecessors or the ARM processors used in their successors. The Apple–Intel architecture, or Mactel, is an unofficial name used for Apple Macintosh personal computers developed and manufactured by Apple Inc.
