4. Mac - Model 1A+/2A : Troubleshooting the Touchscreen

Modified on Fri, 7 Jun at 5:24 AM

You need Mac OS Mojave or above for the touch function to work.

UPDD does not have to be installed for the Mac OS to detect the Touchscreen hardware.

First, we need to check if the Mac OS finds the Touch hardware.

Follow the steps:

1. Connect USB-C to USB-A cable directly to the Mac’s USB port without going through a hub or the Y-cable or any other middleware.

2. Then connect the HDMI for video signal (if there is no video signal the monitor will power off).

Alternatively to the hdmi, you can try a Thunderbolt (USB-C to USB-C) cable directly on the Mac, but the best method to test is with the provided USB-A cables.

3. Open the System Report of the Mac and check under the USB Tree, it should display

MP Touchscreen

Manufacturer: MP Controller Touch Display

Alternatively to opening the System Report (needs to reopened every time you unplug a USB device), you can download 'this' small utility app (right click and click "save link as..." to download it) which when you run it, it shows if the MP Controller’s touch software is properly connected and found by Mac OS.

Please note that the cursor of the mouse must be on the MP Controller for the touch function to work properly . If it located on your main monitor and when you touch the screen it will move the mouse in the main screen. UPDD transfers the touch on the MP Controller screen area automatically, regardless of the position of the mouse.
