Rosetta 2 an emulator built into macOS Big Sur that will enable ARM Macs (M1) to run old Intel applications. Rosetta 2 essentially “translates” instructions that were written for Intel processors into commands that Apple’s chips (SoC) can understand. Developers won’t need to make any changes to their old apps; they’ll just work.
Rosetta 2 works with Intel-based apps distributed through the Mac App Store, and desktop applications downloaded and installed from external sources.
To the user, Rosetta is mostly transparent. If an executable contains only Intel instructions, macOS automatically launches Rosetta and begins the translation process.
When launching any Mac apps for the first time on Apple Silicon Macs, the apps will bounce in the dock for approximately 20 seconds while the Rosetta 2 translation process is completed, with all subsequent launches being fast.
