I'm getting the following error with a genuine Arduino Uno on Mac OSX10.11 El Capitan when uploading to it (the green light is on, the orange light flashes intermittently while attempting to upload). Here's the error:
avrdude: stk500_recv(): programmer is not responding
I've tried all the solutions I can find. I've selected the correct port and board. I've tried pressing the
reset button before uploading. I've tried different USB cables. I've tried unplugging and replugging everything. I've read this:

I tried the FTDI fix, (but not sure if was actually able to disable the mac drivers, or which drivers are now running, the example I tried is for for OSX 10.10 Here). I ran into the following issue in the Terminal:
Mac-Pro:~ m$ cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns
Mac-Pro:PlugIns m$ sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled
mv: rename AppleUSBFTDI.kext to AppleUSBFTDI.disabled: No such file or directory
I don't get why it says
No such file or directory because
AppleUSBFTDI.kext definitely exists as a package in the Extensions folder, but I guess it's talking about another file named that in the plugins folder? Confusing ... Was this moved in OSX 10.11 and should I rename this package in the Extensions folder?
I did download and install the old FTDI drivers, but I don't know if they're actually the ones working right now? How do I clarify that?
Any ideas how to get this working?
I also tried on an old Mac Laptop 10.6.8 - Snow Leopard, and had the same issue :(
