Rosetta, which is Apple MacOS software, is being used to support Intel based MacOS apps on Apple M chip based MacOs platforms. It acts as a translation layer, allowing these apps to work on the new Mx architectures. 

If you’re using an Apple Silicon Mac (M1, M2, M3, etc.), you’ll need to install Rosetta 2 to run Intel-based apps smoothly such as Roqos SASE application. 

When you are being prompted as shown below, click the Install button.
