You don`t have the option to switch between the IntelHD and GT540m on your BIOS???

no this is the problem but there is a possibility to fix it with software?

Using software unfortunately no (when both GPU`s are recognized yes)...



There`s some guys that apparently, using a patched DSDT, was able to power off the IntelHD one to force OS X use the NVidia one on this thread > Nvidia Gt5xxm Dev - Project OS X Forums

Take a look and tell the results...

tomorrow i will go to register to this page an try it, thanks for your help
good night
