My anecdotal evidence is that the cable with the Prolific chip paired with the Prolific driver from the Prolific website gave me the garbled data, while the FTDI cable with no extra effort has been working great. The cable is made by a different manufacturer, but the product description usually tells you which “chipset” is embedded in the cable.
These companies design the silicone that lives inside a small black box that lives on a printed circuit board that lives inside your converter cable. ProlificĪdmittedly, I’m less certain about this part of the amazing trick.Īs far as I am aware, there are only two manufacturers of USB-to-Serial converter chips at the moment: FTDI and Prolific. I had no idea because the last time I tried using a USB-to-Serial cable on macOS was with version 10.8. I can’t find the Engadget article about the five minute time slot Phil Schiller devoted to announcing this revolutionary innovation at WWDC, but here is the official Apple tech note. MacOS includes kernel drivers for FTDI chips as of version 10.9, aka “Mavericks”, released in 2013. Use a version of macOS newer than 10.9 and use a cable with FTDI chip.ĭo this and you will never have to fuzz around with manually installing drivers from shady websites! And you can now unplug the USB-to-Serial cable while your computer is sleeping without provoking a crash – amazing! macOS >= 10.9 comes with (working) FTDI drivers How do I know this? Because I wasted three long nights debugging the problem.īut I’m a changed person now because I learned this one amazing trick for making USB-to-Serial just work on macOS: The one I pulled out of a drawer this week randomly flipped the most significant bit of every character. My relationship with USB-to-Serial cables has been one of disappointments, crashed computers, and garbled data. One simple trick for USB-to-Serial on MacOS XĬall me a Luddite if you wish, but I lament the lack of serial ports in modern laptops.
