Fix FTDI DMX interface & Arduino on OSX 10.9+ Mavericks

Apple recently decided to make their own FTDI driver with the release of OSX 10.9 Mavericks. This broke compatibility with Arduino & USB DMX interfaces based on an FTDI chip. Here is how to disable the new driver and use the old FTDI driver. All your apps will be working again like they should.

Compatible with OSX Mavericks+ 10.9.0 / 10.9.1 / 10.9.2+

Fix FTDI Drivers

First, download the “OS X FTDI Driver Control” app Here, extract and run the application :

FtdiDriverControlApp

On the main screen, it should say that the FTDI driver is “ENABLED”, this means that the Mavericks driver is loaded and your DMX software does NOT work. to disable the driver, click the big button:

FtdiDriverControl_Main

The app will ask for your admin password,

FtdiDriverControl_pw

Fill in  your password and click “Ok”. Your Mavericks driver is now Disabled and your software should work again.

This fix the OpenDMX alright. But i must share my experience using QLC+ with a Emtec OpenDMX in one USB port and an Arduino in other USB port. I could only use one device with this fix.

This fix does not seem to work on Yosemite it seems to disable Apple’s FTDI Driver but new FTDI driver does not work?

Doesn’t work on the latest Mac OS X Yosemite DP build. Did you find solution to fix it?

Any progress. Yosemite has been a seamless transition except for killing my ability to communicate to all my FTDI devices

Anyone figure out how to get the FTDI chip sets to work on the usbserials for Yosemite? I can see my device and it works enough to see the scrolling command-line-interface of my serial application, however I’m unable to use my keyboard to put any input into the terminal emulator software, regardless of the emulator I’m using “SecureCRT, terminal, etc.”

Hi Steven, I am a noob at programming and stuff, even with the manual of FTDI i didn’t get my interface working on a mac. The first two steps were doable for me, but i couldn’t copy the file into that library or so. The interface works fine on a windows laptop, but i rather prefer my Macbook. After i didn’t get any further with the manual of the website of FTDI, i tried this step. But, of course, because i can’t install the driver, my macbook can’t find the driver so this didn’t work either. What can i do… Read more »
