Why cant my macbook air see my dj controller when i plug it into my usb port

Hey there Crmonty,

Thanks for reaching out to the Apple Support Communities. If having issue with your USB device not working as expected when connected to your MacBook, give the steps listed in the following resource a try that can help: If a USB device doesn’t work with Mac - Apple Support

- Check the power, port and cable connections: Make sure the USB device is turned on and its cables are properly connected. If your computer has more than one USB port , switch the device’s cable to another port. If you still can’t use the device, contact the manufacturer for more information.

If you can use the device after switching ports, connect another device to the first port. If you can’t use this device, shut down the computer and unplug it from the power outlet. Wait about a minute, then plug it back into the power outlet and start up your computer.

If you still can’t use a device with the port, your computer may need to be serviced. See Find out how to service or repair your Mac.

- Check for missing software: Make sure you installed the latest software for your device. Visit the manufacturer’s website for any updates.

- Check the USB hub: If the device is connected to a USB hub, make sure the device and the hub are the same speed. Connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on.
