- MacOS Sierra (or newer) — check under System Preferences > Security & Privacy to make sure the software is allowed to run.
- Use a high quality USB cable. Some cables are not capable of sustain high current or have a low quality connector that may not give all the required power RF Explorer needs, particularly when charging the unit. Before you try anything else, make sure you test 2 or 3 different cables. This is the most common problems experienced and reported by users.
- Some USB cables designed for cell phones include incompatible, internal resistors (designed to identify them as proprietary) and will not work with RF Explorer.
- Check the internal device CONFIG MENU has the USB Bauds to 500Kbps (not 2400bps).
- To check if the Silicon Labs driver is correctly installed and the device is being recognized, connect the device to USB port, open a terminal window, and run the following command:
If the device is recognized then the response should be:
If you do not get this response then try with a different USB cable.
Knowledge Base and Frequently Asked Questions (FAQs)
In the latest versions of the MacOS, Apple changed the security settings for installing drivers and — in doing so — broke every application that installs drivers for non-Apple devices. Drivers that worked in earlier versions of the MacOS are no longer allowed to be installed and run under the new, default security settings. The only solution is to manually install the driver. Below is a link from the RF Explorer team with instructions on how to install the Silicon Labs driver on your MacOS:

The other most common problem is with the USB cable — not all USB cables are created equal (see below).
Also — in the event the ‘Run’ button is disabled (or “grayed-out”), use the RF Explorer’s built-in LCD menu to navigate to the ‘CONFIG MENU’ and confirm the ‘USB Baud’ is set to ‘500 Kbps’ (and NOT 2.4 Kbps).
Troubleshooting Connectivity Problems (from the RF Explorer Team)
The Touchstone-Pro software application is designed to be run with ‘Administrator’ privileges because it needs to write debug and data files to disk while executing. This requirement may prevent the application from running when launched from an account with only ‘Standard user’ privileges. There is, however, a workaround — complements of Gary Border (Adjunct Associate Professor, Bowling Green State University). His instructions are outlined below:
