After Apple updated their native requirements for drivers in Catalina and newer OS versions, the Silicon Labs team has been working hard to provide compatible drivers to comply with these requirements.
We are happy to announce these compatible USB drivers, version 6, are available and suitable for macOS latest OS versions. If you are using any third party software such as Touchstone or Vantage, or using our free VirtualMachine www.rf-explorer.com/vm or equivalent solution with Parallels, you can now use RF Explorer Touch and other compatible software successfully in your macOS Catalina and newer versions.
For more details download latest drivers from https://www.silabs.com/documents/public/software/Mac_OSX_VCP_Driver.zip and make sure to read the included release notes.
