Hi Guys,
I installed ''macOS Sierra'' on a Dell E6420 i7 with Nvidia dedicated Gpu. Everything's seems to works except that the laptop not remembers the audio level when I boot again from sleep or from zero it put the level on the maximum level (it can be very annoying if I not remember this and play a song direct after the start of my computer) and that I not see the brightness indicator level on screen when I reduce or augment the brightness some guys telling me I have to setup the NVram to the audio level problem but how do it ? And if you have a solution about the brightness indicator level and the cdmi port not working I will take it too.
Thanks in advance
