Hello all,
I know this topic has been discussed in depth already in many other forum posts, but I have not had any success with any of the proposed solutions so far, so I thought I would ask to see if maybe something has changed.
I recently upgraded my Mac from Snow Leopard to Mavericks (v10.9.5). As many of you probably already know, Mavericks causes the following error when uploading a sketch:
avrdude: stk500_recv(): programmer is not responding
My understanding is that the issue derives from the fact that Apple has released their own FTDI drivers.
I have tried to disabled this driver with the following (often recommended a solution):
cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns
sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled
sudo touch /System/Library/Extensions
And then restarted my computer.
I then reinstalled the VCP FTDI driver.
After doing this I can see the /dev/tty.usbmodem1421 device, but I still get the above error when uploading a sketch.
"ls /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns" shows AppleUSBFTDI.disabled
"ls /System/Library/Extensions/" shows FTDIUSBSerialDriver.kext
Has there been any changes since this solution was originally posted that I should be aware of?
I also have the PL2303 Prolific driver installed, could this be causing a problem?
I should also add that I have verified that my Arduino and usb cable are not the problem, by uploading a sketch successfully from another machine.
