A bit of reading shows that the touchpads on modern Macbooks use BCM5974, which "reports both mouse and keyboard events via different interfaces of the same usb device." [https://www.kernel.org/doc/Documentation/input/bcm5974.txt]. This is different from the original atp hardware, and there might be some additional work required here. I'd prefer to add support for something recent. Referring to the sources of the bcm5974 driver in linux, I find we should aim for something at least as recent as a MacbookPro8 (unibody, March 2011) or MacbookAir3,2 (unibody, late 2010). thanks, --=20 --5iGhfPB9eI6B3K3aMwlRIWdQCE0vSsWts Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.20 (GNU/Linux) iQIcBAEBAgAGBQJS5MUSAAoJEPU+O5mH1kD8kJMP/2IDNODKNYCEOA3vzd1JvRTi +S3Bmdc1QeBdkT/HZ3Elp+u/4LJSx8H47aCloGS8NulNwvi5j9wpL0eaxEsH/QEv 6+2CdbPRopOshscJXuZIF7oXcgiDo3PY9ElOCwpsl5jlKuiWjtjayMkfBs+nrM80 ADCrBvW/QaFF0iuW+M6Tr8tJYcnN0jvlk4Y+wClnpnsk+QHcJAdRrKkI/Har+lox uaWzTsCGaqTVtYdfc9smUJz5D0mZSuayYqpmVpqK6+ZMfdpPpSdI7AucDF80JdKG cecG+6kNjna0XgjccYjmjFsozEC4MGaz3wOHMz+0iY04RpZnHHAJdvyZmcLh4oQz 31FcKO04u81O6FypekvQm707m+z/tVyGiXKKVoWUf96EqKyEDt+2c1o7L6X7Pfkg tIh3cIxsmjerSQoeFCrJzD0eY5CL7isF7F6M8yBjqX7U/w8YMWcUucn2WPFCCF/Y MhzdYOm2flhpcjYLmVoQ3264vZbYVrY3t2QnlcFahY/iSr8dX1S+AwQJjR+1FLn8 1g34ZqHubpgYpxwkhodJvmIvruMmSV1BzytS0aZKk5jsv7AxlwyBk88nk8g7rCcS 6KVeGvSF4qOT3SzAxQYULtkaSNrXls8Irg0d6K4Ac8/gODMRlr6/2Pvjt+khSwAN T5ki8FZXCJwrwnbzzT1p =L2xm -----END PGP SIGNATURE----- --5iGhfPB9eI6B3K3aMwlRIWdQCE0vSsWts--
