It’s also incredibly useful for app developers and technical support staff, who often need an array of operating system versions for testing and troubleshooting.Įmulation generally works at an instruction level. Such an approach can give you the best of both worlds, where you can use the latest hardware and operating system while still having access to previously purchased apps that run only in unavailable machine configurations. Crossing the Chasm: Emulation and Virtualizationīoth emulation and virtualization let you run one or more apps or entire operating systems within a distinctly separate operating system from the one that manages the host computer-the actual computing hardware. Will someone build a trestle highway? Let’s explore the concepts first. Apple’s limited Rosetta 2 emulator provides one of those Indiana Jones rope bridges across the chasm. Though they may seem to carry out a very similar function, there’s a wide gulf between emulation and virtualization.

But there’s more to come that could improve the transition from Intel to Apple silicon for Mac users-like a virtualization app that would let us launch 10.15 Catalina or previous Intel-only versions of macOS, or Intel flavors of Windows, Linux, and other operating systems. Virtualization lets Apple (and other companies) keep older operating systems alive for a while, or even indefinitely, by creating a bubble in which older code can run natively, without realizing it’s not controlling a hardware computer.Īpple’s latest entrant in the emulation field is Rosetta 2, which enables Intel-based apps to run on Apple’s M1 chips. Emulation lets a computer run code intended for a different CPU, like a Mac with an Intel processor running code written for a Motorola chip. Over the decades, Apple has managed several successful processor and operating system migrations with a combination of emulation and virtualization. #1604: Universal Control how-to, show proxy icons in Monterey, Eat Your Books cookbook indexĮmulation, Virtualization, and Rosetta 2: A Blend of Old, New, and Yet To Come.#1605: OS updates with security and bug fixes, April Fools article retrospective, Audio Hijack 4, 5G home Internet.#1606: Apple's self-sabotaging App Store policies, edit Slack messages easily, WWDC 2022 dates.#1607: TidBITS 32nd anniversary, moving from 1Password to KeePass, pasting plain text, Mail fixes anchor links, RIP Eolake.
