I am trying to connect a FTDI USB/Serial cable to my Macbook (Catalina OSX) and I understand that there have been some problems with the new Apple driver. How do I get this working?

I have had no issue with USB-COMM422-PLUS1, USB-COM485-PLUS1, and

TTL-232R (both 5 and 3.3 volt). They were plug and play with no

additional drivers needed. They show up in /dev as tty.usbserial-xxxxxxx,

where the X's are a device identifier.


The only time FTDI drivers are needed if you wanted to access the devices

directly and not a USB CDC device.

It is possible that you have a borked device. Just because

it is new does not mean it is not faulty.


I tested all the devices mentioned before posting

on an iMac running 10.15.6 with latest supplemental

update and have never installed any FTDI drivers.


BTW, if you have installed any drivers, go to FTDI and

find out how to remove them and start over.
