 The imbushuo MT2 USB driver is a UMDF driver. Windows Driver Signature Enforcement does not block the loading of self-signed UMDF drivers. This unfortunately does not apply to KMDF drivers such as the imbushuo bluetooth driver for the MT2 and this is the reason why this project only supports the USB version of the driver. On a personal note I prefer to use the MT2 via USB: the MT2 can be switched between different computers without problems, no worries about the battery, the driver cannot bluescreen the PC and the USB version of the imbushuo driver in particular has proven to be very stable over the years.
 
 When you click on "Install Driver" in the Control Panel, all MT2s connected to the system are disabled and then the AmtPtpDeviceUsbUm.dll file is updated directly in the Windows Driver Store. The owner and ACL of the file are modified to allow copying, and are restored to their original state at the end of the procedure. At the end of the copy, the MT2 is re-enabled. This procedure is not supported by Microsoft, but is commonly used during driver development and does not put system security at risk (as long as the file you are copying is trusted).

+**If your Magic Trackpad 2 is with Lightning Port (before Oct 2024), the installation is finished. If it is with USB-C (after Oct 2024) then this further step is necessary:**

+Manually choose the drivers in Device Manager for the Human Interface Devices with the Instance Path that matches this: ```USB\VID_05AC&PID_0324&MI_00\***``` & ```USB\VID_05AC&PID_0324&MI_01\***``` to be the Apple USB Precision Touchpad Device (User-mode) by Bingxing Wang (imbushuo). This can be done by double-clicking the device item in Device Manager -> (Details Tab) Update Driver -> Browse my computer for drivers -> Pick from list of drivers -> Uncheck Show compatible hardware.
