Installing GNS3 on Mac

At the time of this writing, the current version of GNS3 is 0.7.4.  Therefore, we will be installing version 0.7.4.  Version 0.8.1 is currently in Beta.  I just got my MBP 13″ a yesterday, and decided to install GNS3.

1. You can download GNS3 from here
2. Double click the .dmg file and drag and drop the into your Application folder.  Once you put a copy of GNS3 to the application folder, you should be able to open GNS3.  See Figure 1.

3. Now, the Dynamips will fail; therefore, you would need to map it.  Open GNS3->Preferences->Dynamips->Executable path:.  Then click the browse option and locate the the right dynamips for your system.  I have a x64 MBP, so make sure that you select the right one.  See Figure 2.

4.  Once you have selected the Dynamips, click Test and should say “Dynamips successfully started”.

At this point you should be able to use GNS3 on your Mac.


About networkshinobi

My name is Karlo, I work as a Network Engineer. A little about myself. I started as a PC gamer back when I was in high school. PC gaming became my addiction and pushed me to learn more about computers. Slowly got my some certifications and landed an IT Tier 1 Helpdesk job. This job opened the door for me to work to push further on my certifications and going deeper into the IT world. My goal was to get my Cisco CCIE Routing and Switching, but my journey for CCIE has changed due to I always ended up working on non-Cisco network appliances. Therefore, I have to pivot and decided to jump to the dark side and go with Juniper. Hopefully, I would get my JNCIE in the near future. All the entries/post I made are based on my views, opinion and for educational purposes only. If you see some mistakes, feel free to drop some comments. I would appreciate all the helpful comments. Thanks
