OS X Mavericks (10.9) - IMPORTANT

OS X Mavericks (10.9)- IMPORTANT PLEASE READ

Update

A new USB driver implemented by Apple in Mavericks breaks the USB communications between DMXIS/D-Pro and any Enttec USB-DMX interface.

Solution

The solution is to disable the new Apple driver using the following utility (click here to download)

FtdiDriverControl app

  • Simply run the utility, click the button and type in your password.
  • You must be logged into OS X as an admin user (verify this from System Preferences > Users & Groups)
  • You must have a non-blank password configured (see http://support.apple.com/kb/PH13861
Technical stuff

Both DMXIS and D-Pro use the FTDI D2XX driver to communicate with Enttec hardware. For some (as yet unknown) reason, Apple have written their own D2XX driver for Mavericks, effectively disabling any application which uses the standard D2XX library. It's likely that this problem affects every D2XX application on the planet, not just DMXIS & D-Pro, so I'm sure the next 72 hours will reveal a few complaints on the Interwebs, hopefully some further discussion, and perhaps an official solution. We'll need to wait and see.

In the meantime, our original advice remains - do NOT install Mavericks. If you already have and are stuck with it, use the workaround above.
