If the touch works but affects your other display, then you need to move the mouse pointer to the MP Controller display. This can be done automatically when you touch the MP Controller display instead of manually having to move the cursor by using UPDD . Additionally, here are some other utilities that can move the mouse cursor to other displays. Model 1A Touch Function The Touch hardware shows as "Multi-Touch by G2TSP" in the System Report. UPDD is required for touch functionality on MacOS Catalina and later for Model 1A. See here If it does not show up in the System Report, it is a connection issue. Connect the cable provided directly on the Mac (not through a hub or docking station or the Y-cable) and reload the System Report. Using a stylus with the touchscreen: The touch screen does not work a stylus but it does work with pens that have a rubber tip. These are Capacitive Stylus Pens, as this one 2. MacOS Full screen mode and Window mode The MP Host plugin can operate in Full screen mode and Windowed mode. You can select this option from the right click menu We recommend running the MP Host "In Window" mode and disable the MacOS top bar for secondary displays via Mission Control, Spaces. See how to do this  here If Spaces is not disabled then "In Window" mode will show up the top bar of Mac OS on top of the MP Host window. If you run the MP Host in Fullscreen mode, then the top bar will not show up on any display. 3. Stylus pen for the touch screen You can use a stylus pen made for capacitive touch screens.

Mac - Hide the MacOS top bar from the MP Controller First, set the Main display in macOS to be your other display, not the MP Controller Then, In Mission Control, under System Settings,  disable  the option: "Displays have separate spaces" Choose "Log Out..." from the Apple Menu Log back in as you would normally.  See tutorial video on YouTube You can also move the top bar as shown  here To move the Dock, right click on the Dock and choose another position for it: Note that, if the display arrangement is vertical then the Dock will appear at the bottom of the bottom display. It's not possible to set the Dock at the bottom of the top display. If the current possition of the Dock is on the MP Controller, choose another option and it will be moved to another display. For example, if it is on the Right of the MP Controller, choosing Left will be moved to the left side of the adjacent monitor that is on the left of the MP Controller.     5. MacOS Dock appears on the display of the MP Controller If you place the displays on top of each other (Display arrangement) Mac OS places the dock on the bottom display  This is done by Mac OS and it happens with all displays. If you arrange them side by side then the dock can be placed on either display. 6. Select the target monitor for the MP Controller The first time you load the MP Host plugin, it will be displayed on your main monitor.  You need to select the target monitor from the big window of the MP Host plugin. Right click anywhere on the main black area of the big window and from the menu under Monitor, select the target monitor which will be the last  monitor in the list. When you right click anywhere on the empty area of the main window the following menu will show up as shown in this video The same principle applies to other MP Controller plugins or apps. Each app has it's own properties file in the /MP/Host folder where it stores the selected target monitor. Troubleshooting the right click: If you don't see the menu when you right click, see the following suggestions: 1. On the Mac, using a Mac mouse, e nsure you have set the Mouse button Secondary Click to "Click on Right Side" If you are using an Apple Magic Mouse, you have to press the  Control key and hold it while you right click to generate the right mouse click. 2.  The controller display should be set as Extended Display . Check the arrangement of your displays. It is adviced to place the mp controller left ofr theright of your main display, on Mac or Windows.  3. Try using a mouse that has a right click button instead. 4. Additionally, if you installed UPDD you can right click by touch and hold on the main area of the MP Host plugin. 7. Mac - MP Touch Utility for moving the mouse cursor to the touch screen MacOS does not support touch displays natively and it sees them as a mouse trackpad. This means that when you touch the touch screen the mouse will move at the current location. If it is on your main monitor it will move the cursor there just like a mouse. To address this problem we have created a small utility that takes the mouse cursor automatically to the controller's touch display when it detects a touch gestrue on the controller's display. The utility supports Model 2A. The installer/uninstaller can be downloaded from  here While this utility serves its purpose, UPDD provided by Touch Base for the MP Controller is a more advanced tool that offers many benefits and although it is optional we recommend it. See here If you are already using UPDD you should not install this utility because it will conflict with UPDD. Uninstall UPDD and install this utility. The installer will not let you install it if UPDD exists on your computer. How to install Run the installer and enter your password when asked. Click Allow when asked about System Events. and then click OK  Enable it in Accessibility under Privacy and Security The application should be running and there is a small icon on the top bar. Click on the icon  Select the controller's display (it should be the last display on the list, 1920x1080) Click on Check Permissions, you should see a pop up window Now, quit the Utility and open it from Applications To test it, tap once on the touch screen, you should see the mouse cursor go there at the center of the display. From there you can use it normally on the touch screen. It will start automatically every time you login on your Mac. If you decide to get UPDD later on, you can run the uninstaller and install UPDD.
