GNS3 is a graphical network simulator used by network engineers, students and IT professionals to design, test and configure virtual networks. It supports emulation of Cisco routers and switches, VPCS (Virtual PC Simulator), Docker containers, and various other networking devices and protocols. Users build complex lab topologies without needing physical hardware, making it popular for CCNA/CCNP exam preparation, network design validation, and educational purposes. A native Apple Silicon build has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionA native Apple Silicon build of GNS3 exists and is confirmed to be running on real Macs. However, the official GNS3 download site still primarily distributes the Intel-only version by default, so simply re-downloading from gns3.com will not automatically give you the native build. The most straightforward path to the native client is through the community-maintained gns3-gui-apple-silicon project on GitHub. Clone the repository at https://github.com/mweisel/gns3-gui-apple-silicon, follow the build instructions provided (which involve cloning the GNS3 source, setting up a Python virtual environment, and running PyInstaller), and move the resulting GNS3.app to your Applications folder. Alternatively, check gns3.com directly and look for any official native build announcements or downloads they may have made available since the community builds began. Once you have the native build installed, configure it to point to your GNS3 server (local or remote) via the Settings menu, and you will see noticeably faster performance and better battery life compared to running the Intel version under Rosetta.
