Introduction

What is vTouch Support?
vTouch allows for touch feedback control for external monitors connected to a Mac.
The touch function relates to the processing of the touch events (tap, press, gestures, etc.) performed on the touch device. A common list of touch events and system actions are predefined and can be configured as suits.

NOTE:

Initial Setup

Where to get vTouch Support
vTouch can be downloaded at the “Download” section of each TD display’s product page.
After the download completes, launch the setup file and follow the on-screen directions to install the software.

1. Click the UPDD_06xx.pkg file to open the installation.
2. Input your MacBook password to install the driver.

3. Run the installation to complete the installation process.
4. After a successful installation, there should be two (2) UPDD application icons shown on the top menu bar – UPDD Commander and UPDD Console.

Installing vTouch on Big Sur

For Intel Systems
1. Run the installer.
2. Grant the kernel extension (kext) permission to load, but do not reboot.

3. Grant both updd.app and UPDD Commander.app permission to use Accessibility features.
4. Wait for the installer to finish and restart your system.

For Silicon (M1 chip) Systems

1. Enter the macOS Recovery environment.
2. Go to: Utilities > Startup Security Utility.
3. Select your system, then click Security Policy.
4. Click the button for Reduced Security.
5. Check the box next to Allow user management of kernel extensions from identified developers.
6. Click OK and enter your administrator password when requested.
7. Restart your system after the UPDD installation has completed.

NOTE:

• The reboot will likely be blocked if the installation is still running.
• You must retain the Reduced Security security level for the kernel extension to load in ARM processors.

Installing UPDD in Big Sur
Below are the observed differences when installing UPDD kernel extension version. These instructions refer to drivers created on or after 8th December 2020 that carry the new universal binary codeless kext.
Intel systems The new codeless kext file caused kext load error 71 (an unknown error). You still need to give manual permission to load the kext via the “Allow” button in the Security and privacy dialog to approve the installation of the UPDD software.
Silicon systems In our initial tests with the new codeless version of the kext we were not asked for permission to load the kext nor required to reboot for the kext to load. However, your system may still ask to grant permission to load and require a reboot as shown below. If this is required, and you have not granted permission, Kext error 27 will likely be shown in the UPDD Console. You have to reduce system security to allow the kext to load.

Connection Methods

In addition to downloading the driver, ensure that your monitor and MacBook are properly connected via:

· USB Type-C to USB Type-C

· USB Type-B to USB Type-A

Using the Applications

This section will describe the general use and operation of the UPDD applications.
UPDD Commander
UPDD Commander can setup touch behavior definitions in all applications.

Setup Touch Behaviors for All Applications The touch function options are based on the Mac trackpad. The Touch function relates to the processing of the touch events (tap, press, gestures, etc.) performed on the touch device. A common list of touch events and system actions are predefined and can be configured as suits.

Setup Touch Behaviors for Specific Applications If the touch behaviors under All Applications are not enough for your use case, you can customize touch behaviors for specific applications. To activate, ensure UPDD Commander is open and go to: View > Show Hidden Application Groups.


NOTE: It is recommended to set behaviors for All Applications only. 10

Adjusting the Settings
