The MacBook Pro line launched in 2006 as an Intel-based replacement for the PowerBook line. The first MacBook Pro used an aluminum chassis similar to the PowerBook G4, but replaced the PowerPC G4 chips with Intel Core processors, added a webcam, and introduced the MagSafe power connector. The unibody model debuted in October 2008, so-called ...
From 1998 up until the PowerPC to Intel transition, New World ROM was used for all Macs starting with the first iMac and later expanding to the first iBook and the Blue and White Power Mac G3. Most Intel-based Macs used Apple's implementation of EFI as the boot loader, while those with a T2 security chip used a slightly different approach where ...
Machine checks are a hardware problem, not a software problem. They are often the result of overclocking or overheating. In some cases, the CPU will shut itself off once passing a thermal limit to avoid permanent damage. But they can also be caused by bus errors introduced by other failing components, like memory or I/O devices.
In computing, Machine Check Architecture (MCA) is an Intel and AMD mechanism in which the CPU reports hardware errors to the operating system.. Intel's P6 and Pentium 4 family processors, AMD's K7 and K8 family processors, as well as the Itanium architecture implement a machine check architecture that provides a mechanism for detecting and reporting hardware (machine) errors, such as: system ...
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.

The Mac Pro Server includes an unlimited [8] Mac OS X Server license and an Intel Xeon 2.8 GHz quad-core processor, with 8 GB of DDR3 RAM. [114] In mid-2012, the Mac Pro Server was upgraded to an Intel Xeon 3.2 GHz quad-core processor. The Mac Pro Server was discontinued on October 22, 2013, with the introduction of the cylindrical Mac Pro.

The purpose of overclocking is to increase the operating speed of a given component. [3] Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics controller, but other components, such as system memory or system buses (generally on the motherboard), are commonly involved.
