Rosetta 2's performance has been praised greatly. 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 a high level of translation efficiency is

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.

can make use of
Rosetta 2 to run x86-64 code compiled for Linux, within the virtual machine. Rosetta 2 works as a runtime binary, which is required to be installed on the guest operating system. There have been instances of developers installing this runtime binary on third-party hardware, provided
607:
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
240:. 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 68k and PowerPC code to be interspersed within the same

instruction set; the memory ordering will be different from native x86. Some developers have noted that it might violate macOS's licensing agreements, since the runtime is bundled within Apple's
Virtualization framework.

It translates the apps when you install them, so they can launch immediately and can be instantly responsive. Rosetta 2 can also translate code on the fly when needed.

Because of the greater architectural differences between Intel and PowerPC processors, Rosetta operates at a higher level than the 68000 emulator does, as a
