Apple silicon is a series of system on a chip (SoC) and system in a package (SiP) processors designed by Apple Inc., mainly using the ARM architecture. They are the basis of Mac , iPhone , iPad , Apple TV , Apple Watch , AirPods , AirTag , HomePod , and Apple Vision Pro devices.
The Developer Transition Kit is the name of two prototype Mac computers made available to software developers by Apple Inc. The first Developer Transition Kit was made available in 2005 prior to the Mac transition to Intel processors to aid in the Mac's transition from PowerPC to an Intel-based x86-64 architecture.
The Mac transition to Apple silicon was the process of switching the central processing units (CPUs) of Apple's line of Mac computers from Intel's x86-64 processors to Apple-designed Apple silicon ARM64 processors. Apple CEO Tim Cook announced a "two-year transition plan" to Apple silicon on June 22, 2020. [1]
The software permits many applications compiled exclusively for execution on x86-64-based processors to be translated for execution on Apple silicon. [ 3 ] [ 10 ] There are two ways to install Rosetta 2 on an Apple silicon Mac: either by using the Terminal to install the program directly, or by trying to open an application compiled for x86-64 ...
Most desktops are x86, meaning that a Mach-O with an x86 binary will run without problems if you load the sections into memory. If the Mach-O is designed for iPhone, which has an ARM core, then you would need a PC with an ARM core (does not have to be apple silicon ARM) to run it; otherwise, you would have to change ARM encoded instructions to ...
Xcode is Apple's integrated development environment (IDE) for macOS, used to develop software for macOS, iOS, iPadOS, watchOS, tvOS, and visionOS.It was initially released in late 2003; the latest stable release is version 16, released on September 16, 2024, and is available free of charge via the Mac App Store and the Apple Developer website.

Many silicon architectures such as PowerPC, MIPS, ARM, and x86 built an entire software debug, instruction tracing, and data tracing infrastructure around the basic JTAG protocol. Frequently individual silicon vendors however only implement parts of these extensions.
For iPhones, iPads and Apple silicon-based Macs, the boot process starts by running the device's boot ROM. On iPhones and iPads with A9 or earlier A-series processors, the boot ROM loads the Low-Level Bootloader ( LLB ), which is the stage 1 bootloader and loads iBoot; on Macs and devices with A10 or later processors, the boot ROM loads iBoot.
