which was working properly previously
How do you mean "to contact FTDI directly" ?

PROBLEM SOLVED.After emailing Future Tecnology's support group and getting a reply (wasn't expecting that!) they recommended removing their driver and relying on the built in Apple FTDI driver (AppleUSBFTDI.kext). I did this and all now works. Future Technology's email said:Since 10.9 (Mavericks), OS X has included built-in partial support for some FTDI devices in VCP mode. Starting with 10.11 (El Capitan), Apple's own driver seems to be sufficiently comprehensive that many customers will not need to install FTDI's own VCP unless they wish to use its advanced features such as baud-rate aliasing and configurable latency times.
Hi -I am running into the same issue as you. I have OS X 10.12 and an Arduino UNO, but I don't see the port I need. I've tried disabling the Apple drivers and nothing changes and I have installed the FTDI drivers and CH34x drivers. Nothing still.What do you mean by "removing their driver and relying on the built in Apple FTDI driver"? How do you remove their drivers?Thanks,Sara
