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.
