Premium USB to Serial Port RS232 Adapter For PC Mac Linux This USB to serial port adapter cable is a great accessory item for laptop and desktop computers that do not have a COM or DB9 serial port. Can anyone suggest a way to use Terminal (or another app) to connect to a USB port to which has been connected a USB to Serial converter cable (USB-A to DB9)? More Less MacBook Pro, Mac OS X (10.4.8).
All my Arduino clones (Uno and Mega) work fine in High Sierra. Let me see if I can find the FTDI driver Some boards use the WCH chips. Those need a different driver.
You should be able to see the Vendor ID in the System Information App and work out from there if you need FTDI, WCH or some other driver. Additionally while searching for this I found reports that the FTDI drivers will actively not work with clone FTDI chips.
(I can see their point, but that could prove very frustrating, punishing the victims not the offenders).
