macOS High Sierra 10.13 introduces a new security feature that requires user approval before installing pioneer DJ ‘s new driver software described as below.

(Note: this does not affect drivers that were already installed before updating to macOS High Sierra 10.13)

When installing pioneer DJ ‘s driver software for the first time on macOS High Sierra 10.13, a pop-up like the screen shot below will appear.

When you see a “System Extension Blocked” message (screen shot above), please click “OK”. You will then need to allow the driver install process to complete. Please follow the instructions below.

1. Open “System Preferences” and click “Security & Privacy”.

2. When the “Security & Privacy” opens, you will see a message below: System software from developer "Pioneer DJ Corporation" was blocked from loading. This message is present in the “Security & Privacy” for only 30 minutes after starting driver installation. When this message does not appear, please install the driver software again.

3. Click “Allow”.

4. When your hardware is connected to your Mac, disconnect and re-connect the hardware.

This issue only affects new drivers installed after updating to macOS High Sierra 10.13. If you have installed drivers for your hardware on a previously macOS or OS X version, you will not run into this issue.

The DJ equipment that requires the above procedure when installing the driver software are as follows: DJ MIXER, DJ CONTROLLER.
