@adam sallimou Your touchpad is not yet supported in the current release. I added support for your touchpad in a test version for you to try. Replace the AlpsHID and VoodooI2CHID kext with the ones in the AlpsHID_PTP.zip.
AlpsHID_PTP.zip
EDIT: Version v1.1 on github also contains additional ProductIDs to support PTP touchpad version: https://github.com/blankmac/AlpsHID
If the kexts works for laptops not already in the compatibility list please join https://gitter.im/AlpsT4USB-TEST-Room/community and let me know about your success or possible shortcoming/improvements.
