About
Prolific USB to Serial Cable driver is a macOS driver package for PL2303 USB-to-serial devices. It installs the PL2303HXD_G Mac driver using a package installer; it is not a general-purpose serial terminal application.
- Provides the PL2303 USB-to-serial driver described by Prolific.
- The driver requires a kernel extension to work.
- Homebrew Cask provides installation and uninstall handling for the driver components and package receipts.
Install with brew install --cask prolific-pl2303. If installation does not complete, the cask advises retrying after enabling the required extension in System Settings → Privacy & Security. Consult the vendor documentation or Apple’s technical note for guidance on kernel extensions.
The vendor page describes the wider PL2303 product family. Specifications shown there for particular chip models should not be assumed to describe this driver package. The supplied package details identify it as a macOS driver but do not specify supported macOS versions or establish compatibility with every PL2303 device.
