I just installed macOS Mojave 10.14 Beta and when i connect an Arduino to the USB port, nothing appears in my Arduino IDE ports list.

if i try ls /dev/tty.* i just see /dev/tty.Bluetooth-Incoming-Port connected. On macOS 10.13 everything was working ok. I tried reinstalling the driver ( http://www.ftdichip.com/Drivers/VCP/MacOSX/FTDIUSBSerialDriver_v2_4_2.dmg ) many times, I also tried following https://learn.sparkfun.com/tutorials/how-to-install-ftdi-drivers/mac but the port never appear. Suggestions?

It's one of the problems of upgrading your system too early on Apple. You will just have to wait for a few days for the device drivers to be fixed. I remember my printer not working when I upgraded to High Sierra. It started working a few days later. The best thing to do is to report this to Apple support. There are other people who are also reporting this bug stackoverflow.com/questions/50731843/… – Nitro
Thank you. I had to install the Beta because I develop apps for iOS. I also tried to write to ftdichip support. – voidbrain
@voidbrain were you able to solve this? – acrogenesis
MacOS beta 3 (8A326h) solved the problem. The port is available again. – voidbrain
Just wanted to follow up. After the Mojave public release, devices show up and software and connect to the COM ports and seems to send and receive data, but I think not all parts of the communication are working fully. I have a device that is sending data back from a request, but I think it's not seeing changes in RTS / CTS / DTR properly. – stef
