On Macbooks with M1 chip (arm64) , Rosetta2 is a translator from Intel x86 to M1 silicon chip.
In order to install Rosetta on your Macbook, enter in the Terminal
softwareupdate --install-rosetta
When you open an app with "Get Info", you can check "Open using Rosetta"
Now these applications will run under an emulation of Intel processor.
In the application "Activity Monitor", in the Kind , the iTerm2 process with Rosetta checked is Intel. The iTerm2 unchecked is Apple. In terms of performance, I notice nothing.
What are the drawbacks to apply Rosetta to any applications ?
- for an app compiled for arm64 chip
- for an app compiled for Intel x86 chip
