Frequently Asked Questions

There is a new feature in Mac OS X 10.13 that imposes a new level of security for the installation of 3rd party drivers. About half way through the Keyspan driver installation, the new OS puts up a prompt telling the user that they can't proceed until they provide explicit permission by opening System Preferences —> Security & Privacy —> General. In that tab you will see some wording to the effect that an Installer from TRIPP LITE MANUFACTURING is trying to install something. The user has to click on the “Allow” button here to enable the installation to proceed. This is only needed once.

Additional FAQs may be available on the USA49WG model support page.
