Everything you need to know about Rosetta 2 on Apple Silicon Macs

With their new processor, Apple’s M1 Macs deliver ground-breaking performance, but applications built to run on Intel chips may need to use the all new Rosetta translation technology in order to run. What is it and what does it do?

Supporting the journey to Apple Silicon

Apple’s decision to migrate to Apple Silicon is history in action. The company now controls the future of all of its platforms and its processors are already impressing users with their performance and stability.

The M1 chip boasts an 8-core CPU and the world’s fastest integrated graphics on a Mac. CPU performance promises to be around 3.5x faster on a MacBook Air, with 5x faster GPU performance, and up to 9x faster machine learning.

That said, applications are built to run on specific processors, and not every developer has done all the work necessary to make their apps run natively on Apple Silicon Macs. M1-powered Macs can run native, universal (in which the installer carries code for both Intel and Apple chips) and Intel apps.

Apple is encouraging developers to release universal apps where possible and is making it possible to run Intel apps on Apple silicon using emulation technology called Rosetta 2.

What is Rosetta 2?

Rosetta 2 is an emulator designed to bridge the transition between Intel and Apple processors. In short, it translates apps built for Intel so they will run on Apple Silicon.
