About:
The Prolific PL2303 driver enables communication with USB-to-serial adapters based on the Prolific chipset. It provides the necessary kernel extensions to allow macOS to recognize and interface with these devices. This driver is essential for connecting legacy serial hardware like microcontrollers, routers, and industrial equipment to modern Mac systems.
Key Features:
  • Support for multiple PL2303 chipset versions (GC, GL, H, HX, X, RA, etc.)
  • Compatibility with standard serial communication applications
  • Automatic device detection and driver loading
  • Support for common baud rates and flow control options
Use Cases:
  • Connecting to routers, switches, and network equipment for console access
  • Programming and debugging microcontrollers (Arduino, ESP32, etc.)
  • Interfacing with industrial machinery or scientific instruments via serial port
Alternatives:
  • CH340/CH341 Drivers – Alternative driver for different USB-to-serial chipsets commonly found in Arduino clones
  • FTDI Drivers – Official drivers for FTDI chipsets, another popular USB-to-serial solution
