The problem is, when you installed the drivers, you didn't allow the installation through the OS security. Follow the instructions here.
Hi,
I've just receive a last Macbook Pro with touch bar and USB-C, I've got a big problem with the bultin soundcard of the DJM 900NXS and the Macbook.
Before I'm connecting the USB directly from my previous Macbook to the DJM 900 NXS for record or use the bultin soundcard.
Now, the Pioneer software recognize the DJM but the DJM didnt show on the sound option, Ableton, or any audio logiciel.
I'm using Mac Os Mojave (10.14.2), my DJM is up to date with 1.3.2 firmware. I've tried with two type of USB cable :
I've tried with this one : https://www.amazon.fr/Cable-Matters-USB-C-Imprimante-Scanner/dp/B00UUBRV9C/ref=sr_1_3?ie=UTF8&qid=1545053675&sr=8-3&keywords=USB+C+to+USB+B
Ant this connector : https://www.amazon.fr/Rampow-Adaptateur-USB-vers-3-1/dp/B07J5CDJ9Z
There is some screenshot of my problem :
Pioneer software show the DJM connected
I've the 1.4.1 software (but it's showing 1.4.0 it's weird)
And there is no soundcard DJM900 appear on Mac Os !
But the Mac seen the DJM 900 connected.

Hi, I've do the installation correctly, the system dont block the system extension and I'm in Mac Os Mojave...
Try this:
- disconnect the DJM from USB
- run the UNinstallation app from within the package
- reboot your computer
- install the drivers
- check that the OS allowed the installation
- connect the USB
- open the Audio MIDI Setup to see if the DJM-900nexus appears as an audio device
I have the same problem!!! :(
"The problem is, when you installed the drivers, you didn't allow the installation through the OS security. Follow the instructions here." This link, doesn´t work
Looks like they updated the document and I hadn't updated my bookmarks -- sorry!
