-At the moment the new Apple Silicon Macs released in November 2020, like the [MacBook Pro 13"](https://www.apple.com/macbook-pro-13/), [MacBook Air](https://www.apple.com/macbook-air/) and [Mac mini](https://www.apple.com/mac-mini/) models with the [Apple M1](https://www.apple.com/mac/m1/) chip do not have native builds. But the Arduino Agent performs well in [Rosetta 2 mode](https://support.apple.com/en-us/HT211861).
+The Arduino Agent is supported both on Intel and Apple silicon computers. This includes devices with the M1, M2 and M3 processors.  
+At the moment the Arduino Agent is only built for Intel architectures, but Apple silicon devices can run it thanks to the [Rosetta 2](https://support.apple.com/en-us/HT211861) translation layer by Apple.
