How to Launch the Intel Version of a Universal Apple Silicon App

Friday March 12, 2021 3:51 pm PST by
Macs powered by Apple silicon, such as the M1 MacBook Pro, can run both iOS apps and Mac apps, but they can also run x86-64 software that's been built to work on Intel architecture, thanks to something called Rosetta 2. Rosetta 2 is the translation layer that enables a Mac with Apple silicon to use apps built for an Intel-based Mac. The first time you launch an app that requires it, an alert ...

Rosetta Mac App Translation Process Can Take 20 Seconds on First Launch [Updated]

Thursday November 12, 2020 11:30 am PST by
Given that Apple's new M1 chip is designed based on ARM architecture, apps built for Intel's x86 architecture will need to be run through Apple's translation layer Rosetta 2 in order to function on Apple Silicon Macs, and this process can take some time. Microsoft this week indicated that when launching any of its Mac apps for the first time on Apple Silicon Macs, the apps will bounce in the ...
