µFR Reader Writer on macOS – FTDI drivers and communication permissions tips
Last Updated: September 9, 2025µFR Reader Writer on macOS FTDI drivers and communication permissions tips *NOTICE: Applicable only to old macOS versions and legacy µFR devices.

Enabling the communication between the software and the USB-connected reader varies depending on the macOS version. The OS versions from Mavericks (version 10.9) and above already have the AppleUSBFTDI driver. The interface is matched to the FTDI kext, which in turn creates a BSD serial port for use at the application layer. The application opens the serial port to communicate with the hardware. On the other hand, the USB-connected µFR devices implement user client drivers to communicate directly with the device from the user space (FTDI D2XX Driver). Therefore, the presence of the AppleUSBFTDI kext might affect communication with the software. Software applications may fail to open a connection with the hardware because IOKit already has matched the AppleUSBFTDI driver to the device.
