I'm currently running into massive issues when trying to turn my Elegoo UNO R3 into a MDS (MAC Deployment Stick), the program I'm running compiles okay but when i try and upload it i get the error below:
avrdude butterfly_recv() programmer is not responding
Until it says Serial port not found or device not connected (something like that)
I've checked in ports and its connected to /dev/cu.usbmodem4211(Arduino/Genuine UNO), ive seen forums stating it needs to be /dev/tty.usbmodem but the drivers is tells me to install doesn't work.
I'm running Mojave 10.14.4 which the latest Arduino build. I've also tried on High Sierra and OS Yosemite to no avail. Can anyone help with this issue
