"Mac Precision Touchpad" driver installed
In case the Mac Precision Touchpad
driver is installed, a Magic Trackpad 2 will not work properly with the Magic Trackpad Utilities.
- With a wireless Bluetooth connection, a Magic Trackpad 2 doesn't work at all. That other driver must be uninstalled.
- With a wired USB connection, a Magic Trackpad 2 works but isn't detected by the "Magic Trackpad Utilities" application. It's enough to reinstall the Magic Trackpad Utilities driver. However it is highly recommended to uninstall that other driver as well.
Wireless Bluetooth connection
To make the Magic Trackpad Utilities work with Bluetooth connections the Mac Precision Touchpad driver must be uninstalled.
Explanation
Usually only one device driver can be installed per device which prevents that incompatible drivers are loaded at the same time.
However Windows has a driver stack where filter drivers can be placed at various levels. The Magic Trackpad Utilities driver sits at a lower level in the driver stack than the Mac Precision Touchpad driver. As a result both drivers are loaded at the same time and block each other.
