“Huge leap forward for the Mac”

Apple announced that they will be transitioning their future Mac lineup from Intel processors to their in house custom made silicon chips. This transition will at least take up to 2 years. They even announced that a Mac with Apple’s silicon will be released later this year.

With Apple’s Silicon, the upcoming Mac lineup will use arm64 architecture. Whereas the older Macs with Intel-based processors used x86–64 architecture. With this transition, Mac devices will be able to run apps made for iOS and iPadOS without any change to the code.

However, because of this transition from x86–64 to arm based architecture, apps made for Intel-based Mac devices won’t be able to run on newer arm based devices. That’s where Rosetta 2 comes. With macOS Big Sur(OS 11), Apple announced Rosetta 2 to ensure these apps to work on newer devices without any hiccup.

So what exactly is this Rosetta 2?

Rosetta 2

Rosetta is a translation process that allows users to run apps that contain x86–64 instructions on Apple silicon. Rosetta is meant to ease the transition to Apple silicon, giving…
