Jan 15, 2021 Rosetta 2 enables a Mac with Apple silicon to use apps built for a Mac with an Intel processor. If you have a Mac with Apple silicon, you might be asked to install Rosetta in order to open an app. Click Install, then enter your user name and password to allow installation to proceed. StoneTable 4.0.10 (no, really, that’s the version number), the List Manager replacement, is now available from StoneTablet Publishing. Among the changes in the new version are support for Mac OS.

Rosetta is a dynamic binary translator developed by Apple Inc. for macOS, an application compatibility layer between different instruction set architectures. It gives developers and consumers a transition period in which to update their application software to run on newer hardware, by 'translating' it to run on the different architecture. The name 'Rosetta' is a reference to the Rosetta Stone, the artifact which enabled translation of Egyptian hieroglyphs.^[1]

The first version of Rosetta, introduced in 2006 as a component of Mac OS X Tiger, was part of the Mac transition from PowerPC processors to Intel processors, allowing PowerPC applications to run on Intel-based Macs. The second version, introduced in 2020 as a component of macOS Big Sur, is part of the Mac transition from Intel processors to Apple silicon, allowing Intel applications to run on Apple silicon-based Macs.^[2]

Background[edit]

Apple has used four series of CPU architectures in its Macintosh line of computers: the Motorola 68000 series, the PowerPC series, the Intel Core series, and its own series of ARM-type processors. Each transition has rendered software produced for the earlier architecture incompatible with the new one, creating a need for software allowing the newer platform to emulate the previous one.

When it introduced its first PowerPC systems, Apple included software in System 7.1.2 and later versions of the operating system to emulate a 68000-series system. This emulator takes advantage of features built into the PowerPC processors, and accesses the very lowest levels of the OS, running at the same level as – and tightly connected to – the Mac OS nanokernel. This means that the nanokernel is able to intercept PowerPC interrupts, translate them to 68k interrupts (then doing a mixed mode switch, if necessary), and then execute 68k code to handle the interrupts. This allows lines of 68k and PowerPC code to be interspersed within the same fat binary.

Rosetta[edit]

Apple released the first version of Rosetta in 2006 when it began switching the Macintosh line from the PowerPC to the Intel processor. It was initially included with Mac OS X v10.4.4 'Tiger', the version that was released with the first Intel-based Macs, and allows many PowerPC applications to run on Intel-based Mac computers without modification. Rosetta is based on QuickTransit technology.^[3] It has no user interface, and launches as needed with no notification of the user, which led Apple to describe it as 'the most amazing software you'll never see'.^[4] Rosetta is not installed by default in Mac OS X v10.6 'Snow Leopard', but is available as an installable option.^[5] Rosetta is neither included nor supported in Mac OS X v10.7 'Lion' or later, which therefore cannot run PowerPC applications.^[5]

Because of the greater architectural differences between Intel and PowerPC processors, Rosetta operates at a higher level than the 68000 emulator did, as a user-level program that can only intercept and emulate user-level code. It translates G3, G4, and AltiVec instructions, but not G5 instructions. Although most commercial software for PowerPC-based Macs was compatible with these requirements (G4 systems were still widely used at the time), any applications that relied on G5-specific instructions had to be modified by their developers to work on Rosetta-supported Intel-based Macs. Apple advised that applications with heavy user interaction but low computational needs (such as word processors) would be best suited to use with Rosetta, while applications with high computational needs (such as games, AutoCAD, or Photoshop) would not.^[6]

Rosetta also does not support the following:^[7]

• The Classic environment, and thus any non-Carbon application built for Mac OS 9 or earlier
• Code that inserts preferences into the System Preferences pane
• Applications that require precise exception handling
• Screen savers
• Kernel extensions and applications that depend on them
• Bundled Java applications or Java applications with JNI libraries that cannot be translated
• Java applets in Rosetta-translated applications, meaning that a native Intel web browser application, rather than a legacy PowerPC version, must be used to load Java applets

Rosetta 2[edit]

In 2020, Apple announced Rosetta 2 would be bundled with macOS Big Sur, to aid in the Mac transition to Apple silicon. The software permits many applications compiled exclusively for execution on x86-64-based processors to be translated for execution on Apple silicon.^[2][8]

In addition to the just-in-time (JIT) translation support, Rosetta 2 offers ahead-of-time compilation (AOT), with the x86-64 code fully translated, just once, when an application without a universal binary is installed on an Apple silicon Mac.^[9]

Rosetta 2's performance has been praised greatly.^[10][11] In some benchmarks, x86-64-only programs performed better under Rosetta 2 on a Mac with an Apple M1 SOC than natively on a Mac with an Intel x86-64 processor. One of the key reasons why Rosetta 2 provides such high level of translation efficiency is the support of x86-64 memory ordering in Apple M1 SOC.^[12]

Although Rosetta 2 works for most software, some software doesn't work at all^[13] or is reported to be 'sluggish'.^[14] A lot of software can be made compatible with the new Macs by the vendor recompiling the software, often a simple task; while for some software (such as software that includes assembly language code, or that generates machine code), the changes to make them work aren't simple and cannot be automated.

Similar to the first version, Rosetta 2 does not normally require user intervention. When a user attempts to launch an x86-64-only application for the first time, macOS prompts them to install Rosetta 2 if it is not already available. Subsequent launches of x86-64 programs will execute via translation automatically. An option also exists to force a universal binary to run as x86-64 code through Rosetta 2, even on an ARM-based machine.

StoneTable 4.0.10 (no, really, that’s the version number), the List Manager replacement, is now available from StoneTablet Publishing.

Among the changes in the new version are support for Mac OS X, the Aqua interface, and CodeWarrior 6. Plus, improvements have been made in the support for the Platinum interface for Mac OS 8 and 9, according to MacTech Magazine.

StoneTable lets you replace the Macintosh List Manager and “leap past its limitations,” according to the folks at StoneTablet Publishing. You can often begin by making minor changes to your application to replace the List Manager by changing the “L” prefix on the List Manager function calls to “TMX_” for StoneTable function calls. Then by adding a few more calls to the StoneTable library you can have columns with different widths and column titles. The product has been shipping since 1992; version 4.0 begin shipping Feb. 1999
