The instructions below have seemed to work for anyone here at Alorium Technology that was observing the FTDI issues. We have found uninstalling the third-party drivers to be a solution. This potentially leads to the mysterious port disappearance issue. So, if you have followed an upgrade path from an older version of the OS without native FTDI support to a new version that has it, there can be contention between the native and third-party drivers. Somewhere around the release of macOS 10.12 Sierra (and maybe earlier), native support for FTDI drivers was included. Earlier versions of Mac OS X did not support FTDI drivers, so users would have to install third-party FTDI drivers. The exact cause of this problem is not certain, but it seems to be related to Apple’s support, or lack thereof, for FTDI drivers in the operating system. Since we’ve seen this issue pop up internally and with many customers, we decided to share what solution has been working for us so far. Rebooting the system can temporarily restore the port, but the problem eventually comes back. The symptoms we have observed generally include the spontaneous loss of the USB serial port connection to the board or loss of the port after disconnecting and then reconnecting the board from the USB programming cable.
Since our boards use an FTDI chip for USB-to-serial communication, we have witnessed some of these issues when working with our boards using Mac and macOS. You can see the below dialog boxes if you have installed driver successfully.
Solution: I am doing all the programming in OS X on another Mac (luckily I have. Download Driver for the Mac OS X version, named 2.2.18 (32bit) Open the driver file which you just download, and double click FTDIUSBSerialDriver104105106107.mpkg After double click, you will see an installer window. Ongoing macOS FTDI driver issues plague many users connecting the Arduino IDE to boards that use an FTDI chip. Install Arduino Uno drivers XP or Windows7 for USB to serial converter.
