Owners of the Rokland n3 long range USB WiFi adapter for Mac can now try the n3 on Mac OS 10.8 Mountain Lion using this special beta software package we have created.
Once you have downloaded the file, open it and- if your Mac already has n3 software previously installed- run the uninstaller first to remove old software.
Then, after restarting, run the installer. When complete, you should be able to connect your n3 to your Mac and use it as normal. There have been no changes made to the user interface.
While we are not able to officially support n3 on Mountain Lion yet, please send your feedback and bug reports to us by email
