Has anyone out there come across a different solution? This does not seem to be working for me. I can get the 1.5.8 IDE to communicate with my Uno, Mega, and Due, but I just purchased 3 Nanos and I can't get any of them running or my lilypad. I have switched out the USB cable a few times and tried both the mv of the Apple Driver as well as trying to use the Prolific Driver. I still am getting no recognition of a usb serial port. If I run ls /dev/tty.* with my Uno attached it reads usbmodem1411 or usbmodem1a121 depending on which USB I use, but with the nano or lilypad attached there is no response. I am using OS 10.9.5 and IDE 1.5.8 with FTDIUSBSerialDriver.kext.
For any others who haven't been able to solve this one yet: if, like me, you decided to go with the cheaper chinese kick off arduino clone boards and had problems similar to this one, please check the following forum post, as it solved the problem for me:http://forum.arduino.cc/index.php?topic=289518.0And another blog site that explains the whole process really simply for noobs like me:http://kiguino.moos.io/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.htmlActually the dude has even mirrored the relevant driver that solves the problem without having to find it on an all chinese or all russian website!
This procedure fixed my problem on Mac OS X 10.9.1 with Arduino 1.0.5 and an OSEPP Uno R3 PlusI was brand new to Arduino and was of course very disappointed when I could not get the simple Blink sketch to load.I searched for quite a while before coming across this post and even then it was with the aid of a colleagueSince this is going to be a problem for anyone with a recent Mac OS it would have been nicer if there was a more prominent way of alerting Mac users. Are Apple aware of the driver issue? Is it an actual problem with the Apple driver or a problem with the way Arduino 1.0.5 is trying to access the driver? I don't really like regressing the driver so it would be nice to know that someone, somewhere is working on a permanent fix for this... Do we need to post somewhere else to get Arduino development to take a closer look?This is the sort of problem that one associates with Windows rather than the Mac!
