A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys. A TPM 2.0 implementation is part of the Windows 11 system requirements. [1]
Boot Camp Assistant is a multi boot utility included with Apple Inc.'s macOS (previously Mac OS X / OS X) that assists users in installing Microsoft Windows operating systems on Intel-based Macintosh computers.
The static chain of trust starts when the platform powers on (or the platform is reset), which resets all PCRs to their default value. For server platforms, the first measurement is made by hardware (i.e., the processor) to measure a digitally signed module (called an Authenticated Code Module or ACM) provided by the chipset manufacturer.
The OSx86 community has been quick to make the necessary modifications to enable Apple's latest releases to run on non-Apple hardware. Within hours of Leopard's release, an AMD/Intel SSE2/3 Kernel Patcher was created that removed the HPET requirement from an original untouched mach_kernel file, a core component of the Mac OS.
Apple's Boot Camp provides BIOS backwards compatibility, allowing dual and triple boot configurations. The following operating systems are installable on Intel x86–based Apple computers: [28] Mac OS X 10.4.7 and later; Microsoft Windows XP, Vista, and Windows 7 32-bit & 64-bit (hardware drivers are included in Boot Camp)
When Secure Boot is enabled, it is initially placed in "setup" mode, which allows a public key known as the "platform key" (PK) to be written to the firmware. Once the key is written, Secure Boot enters "User" mode, where only UEFI drivers and OS boot loaders signed with the platform key can be loaded by the firmware.
XNU ("X is Not Unix") is the computer operating system (OS) kernel developed at Apple Inc. since December 1996 for use in the Mac OS X (now macOS) operating system and released as free and open-source software as part of the Darwin OS, which, in addition to being the basis for macOS, is also the basis for Apple TV Software, iOS, iPadOS, watchOS, visionOS, and tvOS.
The reaction from Mac game developers and software journalists to the introduction of Boot Camp has been mixed, ranging from assuming the Mac will be dead as a platform for game development to cautious optimism that Mac owners will continue to play games within Mac OS rather than by rebooting to Windows.
