| Allowing the process to complete in Security and Privacy This process is necessary only for MacOS prior to Catalina 10.15.5. Do not complete this process if you are running 10.15.5 or higher. A driver conflict will arise. | ||
| See it done in this video or read about it in the text that follows: Installation on the Mac All USB devices require drivers to identify the device to the machine and make it work with the operating system. The drivers for the RT Systems cables are distributed with the installation package for the programmer. Double click on the drivers package to begin that installation. Drivers for RT Systems or Yaesu (SCU-19 or SCU-20 cables) can be downloaded DRIVER DOWNLOAD HERE Note: Sometimes you don't know the process has failed other than "nothing" happens. That is a failure. If you don't see the Driver Installation window open, the process has been blocked. We can help. Feel free to contact RT Systems at 404-806-9561 (Monday - Friday 10-6 Eastern Time) for assistance. | ||
| Step 1: Double click on the drivers package |  | |
| Step 2: Driver installation will begin. Click Continue. |  | |
| Step 3: Enter the User Name and Password of the computer. Click Install Software. |  | |
| Step 4: System Extension Blocked message appears. The message will clearly specify RT Systems Inc. (if installing the RT Systems Drivers) or Prolific Technology Inc (if installing Yaesu Drivers). Click Open Security Preferences on that screen. |  | |
| Step 5: In Security & Privacy: Click Allow button at bottom of screen. The message on this screen will specify "RT Systems Inc" if you are intalling the RT Systems drivers or "Prolific Technologies, Inc" if you are installing the Yaesu drivers. Driver installation will be completed successfully once permission is granted. |  | |
| Step 6: At the end of installation, you are prompted to move the installer to the trash. RT Systems recommends you click Keep on this page. Then if for some reason you need to install the programmer or the drivers again, you have the files right there on your hard drive (although you can download them again in the future). |  | |
| Step 7: Close the installation screen and with the cable connected reboot your computer. | ||
