I do not have a Mac setup for GNS VMs, however basically, this is how you do it:
On the "host" computer, edit the settings for the GNS3 VM
Change the network adapter to "Bridged", and apply
Close the VM settings
Start the VM
Once the VM has finished booting, there should be a blue screen visible
*Make note of the IP address
**Make note of the port number
From a terminal/command prompt on the "client" computer:
Ping the IP noted in step * to ensure you have network connectivity from client to VM
On the "client" computer, in GNS3 client, go to Help->Setup Wizard
Select the bottom option, "Run appliances on a remote computer and can be shared with multiple users"
Click "Next"
Enter the IP from step * in "Host:"
Enter the port from step ** in "Port:"
Uncheck the "Enable Authentication"
Click "Next:
Click "Finish"
Close the GNS3 client, and restart (Ensure that the GNS3 VM is running on the "host" computer
I hope this helps.
