Pen Not Working on macOS (Device Disconnected in GAOMON Driver)

If your GAOMON pen is not working on macOS and the driver shows "Device Disconnected," follow the steps below to identify and fix the issue.

1. Does the pen work without the GAOMON driver installed?
   • Before troubleshooting the driver, check whether the pen works when macOS is using its default input system.
     1. Uninstall the GAOMON Driver - How To Uninstall The GAOMON Driver (for Mac)
        1. To open the GAOMON driver, click the GAOMON Tablet in the top‑left menu bar
        2. Select Preferences
        3. Click Uninstall
           
     2. Reconnect the Tablet
        • Unplug and replug the USB cable after uninstalling the driver.
     3. Set Display to Mirror Mode (Pen Displays Only)
        1. If you are using a screen tablet(e.g., PD series):
           1. Go to: Apple Menu → System Preferences → Displays → Arrangement 
           2. Select the GAOMON display → Right‑click → Mirror for Built‑in Display
              
        2. If you are using a non‑screen tablet, skip this step.
     4. Test the Pen
        • Try moving the pen on the tablet surface.
        • If you use PD1560 or M106K, plug the pen in to charge while testing.
2. The pen works without the driver — what now?
   • If the pen moves the cursor when the driver is uninstalled, the issue is driver‑related.
   • Solution: 
     1. Reinstall the GAOMON Driver - How To Install The GAOMON Driver (for Mac)
     2. After reinstalling, restart your Mac and test again.
3. The pen still doesn't work even without the driver — what should I try next?
   • If the pen does not respond at all when the driver is uninstalled, the issue is likely hardware‑related. Try the following steps:
     1. Change the USB Port
        • Connect the tablet to a different USB port on your Mac.
     2. Try a Different USB‑A Adapter
        • If you are using a USB-C-to-USB-A adapter, switch to another adapter and test again.
     3. Test on Another Computer
        • Connect the tablet to a different Mac or Windows computer.
     4. Try a Different Micro USB Cable
        • If your tablet uses a detachable micro USB cable, replace it with another one and test again.
