This is easy to fix (at least for 300dpi), just change the definition of
the scanner from BGR to RGB in the backend genesys_devices.c and
Genesys_Model hp2400c_model = {
   0, 24, 48,                   /* RGB CCD Line-distance correction in
pixel */
   COLOR_ORDER_RGB,             /* Order of the CCD/CIS colors */
   SANE_FALSE,                  /* Is this a CIS scanner? */
   SANE_FALSE,                  /* Is this a sheetfed scanner? */

Yes it does, when moving head back after lamp warm-up, but does not hit
hard, needs to be fixed.

Can't really help you there, no experience with Mac.
