After lot of efforts and problems to solve, GNS3 is now available in a DMG package for MacOS. This will avoid you to install and compile the dependencies (Python, Qt, PyQt and SIP) and save you some time.

Please note that languages are not included in this package. I will try to change this in a future release. Since this is the first time I made this kind of package, don't hesitate to report any other problems.

We hope you will appreciate this DMG package.
