You should update your ARCHS build setting to remove the i386 architecture. (in target 'libtelnet' from project 'libtelnet'). BUILD FAILED. Do not report this issue to Homebrew/brew or Homebrew/core!
- The difference between amd64 and i386 is that amd64 is 64-bit while i386 is 32-bit.This is the width (in bits) of registers available in the core. Basically the largest number that a 32-bit CPU core can handle in one go is a little over 4.29 billion while a 64-bit core can handle a number of a bit over 18.44 billion, billion.

Additional diagram of macOS architecture (2017 update)
The architecture of macOS describes the layers of the operating system that is the culmination of Apple Inc.'s decade-long research and development process to replace the classic Mac OS.
After the failures of their previous attempts; Pink, which started as an Apple project but evolved into a joint venture with IBM called Taligent, and Copland, which started in 1994 and was cancelled two years later, Apple began development of Mac OS X with the acquisition of NeXT's NeXTSTEP in 1997.
Note that Mac OS X was renamed to OS X in 2012 and then again to macOS in 2016.
Development[edit]
NeXTSTEP[edit]
NeXTSTEP used a hybrid kernel that combined the Mach 2.5 kernel developed at Carnegie Mellon University with subsystems from 4.3BSD. NeXTSTEP also introduced a new windowing system based on Display PostScript that intended to achieve better WYSIWYG systems by using the same language to draw content on monitors that drew content on printers. NeXT also included object-oriented programming tools based on the Objective-C language that they had acquired from Stepstone and a collection of Frameworks (or Kits) that were intended to speed software development. NeXTSTEP originally ran on Motorola's 68k processors, but was later ported to Intel's x86, Hewlett-Packard's PA-RISC and Sun Microsystems' SPARC processors. Later on, the developer tools and frameworks were released, as OpenStep, as a development platform that would run on other operating systems.
Rhapsody[edit]
On February 4, 1997, Apple acquired NeXT and began development of the Rhapsody operating system. Rhapsody built on NeXTSTEP, porting the core system to the PowerPC architecture and adding a redesigned user interface based on the Platinum user interface from Mac OS 8. An emulation layer called Blue Box allowed Mac OS applications to run within an actual instance of the Mac OS and an integrated Java platform.[1] The Objective-C developer tools and Frameworks were referred to as the Yellow Box and also made available separately for Microsoft Windows. The Rhapsody project eventually bore the fruit of all Apple's efforts to develop a new generation Mac OS, which finally shipped in the form of Mac OS X Server.
Mac OS X[edit]

A diagram of the Mac OS X architecture
At the 1998 Worldwide Developers Conference (WWDC), Apple announced a move that was intended as a response to complaints from Macintosh software developers who were not happy with the two options (Yellow Box and Blue Box) available in Rhapsody. Mac OS X would add another developer API to the existing ones in Rhapsody. Key APIs from the Macintosh Toolbox would be implemented in Mac OS X to run directly on the BSD layers of the operating system instead of in the emulated Macintosh layer. This modified interface, called Carbon, would eliminate approximately 2000 troublesome API calls (of about 8000 total) and replace them with calls compatible with a modern OS.[2]
At the same conference, Apple announced that the Mach side of the kernel had been updated with sources from the OSFMK 7.3 (Open Source Foundation Mach Kernel) [3] and the BSD side of the kernel had been updated with sources from the FreeBSD, NetBSD and OpenBSD projects.[2] They also announced a new driver model called I/O Kit, intended to replace the Driver Kit used in NeXTSTEP citing Driver Kit's lack of power management and hot-swap capabilities and its lack of automatic configuration capability.[4]
At the 1999 WWDC, Apple revealed Quartz, a new Portable Document Format (PDF) based windowing system for the operating system that was not encumbered with licensing fees to Adobe like the Display PostScript windowing system of NeXTSTEP. Apple also announced that the Yellow Box layer had been renamed Cocoa and began to move away from their commitment to providing the Yellow Box on Windows. At this WWDC, Apple also showed Mac OS X booting off of a HFS Plus formatted drive for the first time.

Mac transition to Intel processors |
---|
The universal binary format is, in Apple parlance, a format for executable files that run natively on either PowerPC or Intel-manufactured IA-32 or Intel 64-based Macintosh computers. The format originated on NeXTStep as 'Multi-Architecture Binaries', and the concept is more generally known as a fat binary, as seen on Power Macintosh.
With the release of Mac OS X Snow Leopard, and before that, since the move to 64-bit architectures in general, some software publishers such as Mozilla[1] have used the term 'universal' to refer to a fat binary that includes builds for both i386 (32-bit Intel) and x86_64 systems. The same mechanism that is used to select between the PowerPC or Intel builds of an application is also used to select between the 32-bit or 64-bit builds of either PowerPC or Intel architectures.
Apple, however, continued to require native compatibility with both PowerPC and Intel in order to grant third-party software publishers permission to use Apple's trademarks related to universal binaries.[2] Apple does not specify whether or not such third-party software publishers must (or should) bundle separate builds for all architectures.
Universal binaries were introduced into Mac OS at the 2005 Apple Worldwide Developers Conference as a means to ease the transition from the existing PowerPC architecture to systems based on Intel processors, which began shipping in 2006. Universal binaries typically include both PowerPC and x86 versions of a compiled application. The operating system detects a universal binary by its header, and executes the appropriate section for the architecture in use. This allows the application to run natively on any supported architecture, with no negative performance impact beyond an increase in the storage space taken up by the larger binary.
Starting with Mac OS X Snow Leopard, only Intel-based Macs are supported, so software that specifically depends upon capabilities present only in Mac OS X 10.6 or newer will only run on Intel-based Macs and therefore does not require Intel/PPC fat binaries. Additionally, starting with OS X Lion, only 64-bit Intel Macs are supported, so software that specifically depends on new features in OS X 10.7 or newer will only run on 64-bit processors and therefore does not require 32-bit/64-bit fat binaries.[3][4] Fat binaries would only be necessary for software that is designed to have backward compatibility with older versions of Mac OS X running on older hardware.
The new Universal 2 binary format was introduced at the 2020 Worldwide Developers Conference.[5] Universal 2 allows applications to run on both Intelx86-64-based and ARM64-based Macintosh computers, for Apple's transition to ARM processors.
Motivation[edit]
There are two general alternative solutions. The first is to simply provide two separate binaries, one compiled for the x86 architecture and one for the PowerPC architecture. However, this can be confusing to software users unfamiliar with the difference between the two, although the confusion can be remedied through improved documentation, or the use of hybrid CDs. The other alternative is to rely on emulation of one architecture by a system running the other architecture. This approach results in lower performance, and is generally regarded an interim solution to be used only until universal binaries or specifically compiled binaries are available as with Rosetta.

Universal binaries are larger than single-platform binaries, because multiple copies of the compiled code must be stored. However, because some non-executable resources are shared by the two architectures, the size of the resulting universal binary can be, and usually is, smaller than both binaries combined. They also do not require extra RAM because only one of those two copies is loaded for execution.
History[edit]
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. NeXTSTEP and macOS use Mach-O archive as the binary format underlying the universal binary.
Apple previously used a similar technique during the transition from 68k processors to PowerPC in the mid-1990s. These dual-platform executables are called fat binaries, referring to their larger file size.
Apple's Xcode 2.1 supports the creation of these files, a new feature in that release. A simple application developed with processor-independence in mind might require very few changes to compile as a universal binary, but a complex application designed to take advantage of architecture-specific features might require substantial modification. Applications originally built using other development tools might require additional modification. These reasons have been given for the delay between the introduction of Intel-based Macintosh computers and the availability of third-party applications in universal binary format. Apple's delivery of Intel-based computers several months ahead of their previously announced schedule is another factor in this gap.
Apple's Xcode 2.4 takes the concept of universal binaries even further, by allowing four-architecture binaries to be created (32- and 64-bit for both Intel and PowerPC), therefore allowing a single executable to take full advantage of the CPU capabilities of any Mac OS X machine.
Universal applications[edit]
The I386 Architecture Is Deprecated For Macos
Many software developers have provided universal binary updates for their products since the 2005 WWDC. As of December 2008, Apple's website listed more than 7,500 Universal applications.[6]
On April 16, 2007, Adobe Systems announced the release of Adobe Creative Suite 3, the first version of the application suite in the Universal Binary format.[7]
I386 Architecture Is Deprecated For Macos Windows 10
From 2006 to 2010, many Mac OS X applications were ported to Universal Binary format, including QuarkXPress, Apple's own Final Cut Studio, Adobe Creative Suite, Microsoft Office 2008, and Shockwave Player with version 11 - after that time most were made Intel-only apps. Non-Universal 32-bit PowerPC programs will run on Intel Macs running Mac OS X 10.4, 10.5, and 10.6 (in most cases), but with non-optimal performance, since they must be translated on-the-fly by Rosetta; they will not run on Mac OS X 10.7 Lion and later as Rosetta is no longer part of the OS.
iOS[edit]
Apple has used the same binary format as Universal Binaries for iOS applications by default on multiple occasions of architectural co-existence: around 2010 during the armv6-armv7-armv7s transition and around 2016 during the armv7-arm64 transition. The App Store automatically thins the binaries. No trade names were derived for this practice, as it is only a concern of the developer.[8]
Universal 2[edit]
Mac transition to ARM |
---|
On June 22, 2020, Apple announced a two-year permanent transition from Intelx86-64-based processors to ARM64-based Apple Silicon beginning with macOS Big Sur in late 2020.[9] To aid in this transition, a new Universal 2 binary was introduced to enable applications to be run on either x86-64-based processors or ARM64-based processors.[5]
Tools[edit]
The main tool for handling (creating or splitting) universal binaries is the
lipo
command found in XCode. The file
command on macOS and several other Unix-like systems can identify Mach-O universal binaries and report architecture support.[10]Snow Leopard's System Profiler provides this information on the Applications tab.See also[edit]
- Xslimmer, a commercial Mac OS X application that allows the user to slim down the fat universal binaries by removing the code for the platform that's not in use.
