 ## Apple silicon support
 
 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.
+The Arduino Agent is built both for Intel architectures and Apple silicon devices, but distributed as a single universal executable for macOS.
