Does “open –arch ARCH” engaged on the flawed processor imply that an ARM emulator is current for Intel machines operating macOS?


No, the binary is thick (accommodates a number of construct targets in an utility container) and the one code that may be executed does. I’d say that is the right conduct to open, however I suppose cheap folks may anticipate a strict interpretation and would reasonably obtain an error than an app that would open, however not open.


You possibly can check this empirically by specifying every structure sequentially and operating sudo pattern PID 1 500|head -12 and confirm that the trail, identifier, model, and code sort are native or (translated), the place PID is the method ID of the appliance you open.

On Apple silicon, –arch i386 runs on native ARM, –arch x86_64 is translated Intel code.
