avrdude: ser_open(): can't open device "/dev/cu.usbmodem641": No such file or directory ioctl("TIOCMGET"): Inappropriate ioctl for device Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
Those are the error messages. Its an Arduino Nano Atmega328 and I have the right board selected. However under "tools" the port seems to appear as /dev/cu.Bluetooth-Incoming-Port.
Its really annoying as this board used to work, I've tried manually downloading an FTDI but to no avail. Same with switching ports, restarting the SDK and resetting the board.
