Rosetta 2 in built into macOS Big Sur and Monterey. It only available on Apple Computer with the Silicon M1 / M2 CPU.
There are three categories / types of software that can run on the Operations System.
Only Intel Binary Code. This is software will invoke Rosetta 2 to translate the Intel binaries so the operating system can understand and execute the Application. The Applications must be 64 Bit to function on Big Sur and Monterey
Universal Binary Software. It contains Both Intel and M1 ARMs binary code and refer to ( Universal 2 ) When the user installs a 64 bit Application that contains Both Intel and M1 ARMs binaries - depending on factors, the Operating System may or may not invoke Rosetta 2.
“ Apple Silicon “ Checking in System Information >> Applications >> as of now, only see One Application classified as Apple Silicon and that is “ Rosetta 2 Updater “.
That would make perfect sense since it is specifically designed to operate only on Apple Silicon M1 / M2 ARMs based computers
If you click on the Application and use the two keyboard combination command I.
Inside there there is additional information including the Option to Open in Rosetta 2
