Prolific PL2303 Serial Drivers for M1 Mac with Sonoma

As usual, with each update to Mac OS I seem to have trouble locating a working PL2303 Serial to USB drivers for my older technologies… programming radios, Tripp Lite Keyspan High Speed USB to Serial Adapter USA-19HS, serial/USB GPS units, etc.

Some quick notes that I hope will help me (and you?!) in the future:

  • Visit
  • Click Support
  • Log in with guest and guest as username and password
  • At the bottom look for the link: Click here forĀ PL2303 USB to Serial Drivers.
  • Down on that page look for a section similar to: Mac OS X Universal Binary Driver v2.2.2 (PKG file format) [Or whatever version might have been released since this post]

While I would recommend going through the process above just in case newer versions have been released, I am going to include a direct link to the file for quick access:
PL2303HXD_G_Mac Driver_v2.2.2_20221228.pkg

Note: They also show it as available in the Mac App Store here:
