Once installation is complete, Rosetta will then be available for any of your apps that need it. Just click Install, then enter your username and password to allow Rosetta 2 installation to proceed.

There are several ways that you can learn which of your apps need Rosetta, but regardless, your Mac will ask you if you want install Rosetta the first time you try to launch an app made for Intel. The translation layer works in the background whenever you use an app built only for Mac computers with an Intel processor, and automatically translates the app for use with Apple silicon the first time the app is run. Rosetta 2 is the translation layer that enables a Mac with Apple silicon to use apps built for an Intel-based Mac. The M1 doesn’t make a sound or even get warm.Macs powered by Apple silicon, such as the MacBook Pro models featuring M1, M1 Pro, and M1 Pro Max chips, 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. This same setup turns my 2018 6-core intel MBP into a screaming fireball. There seems to be very little impact on overall system performance because of this, are others seeing the same thing? Something I noticed about x264 when watching Activity Monitor, when I click Stream or Record, it seems to run on the efficiency cores as the additional load appears on cores 4-8 which otherwise show no activity. There is also a workaround out there to enable hardware encoding, however I could not figure out how to properly control the bit rate, it would jump all over the place 5000kbps one second to over 30000kbps. NDI output works, as does the Virtual Camera in Zoom and Google Meet. The NDI plugin does not work out of the box but there is a GitHub post with a workaround that works: CamLink 4K capturing mirrorless camera, a couple of NDI sources and window captures, all working super smoothly. I’ve been setting up an M1 Mini for a live streaming event at work using OBS 26.1.2.
