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

Click on the link and follow the instructions

I follow the step and I get this ''You forgot to press F2 or Fn+F2 at clover boot screen.
Please reboot and press F2 or Fn+F2 to dump preboot log.'' and I tried F2 key only and reboot and retried Fn+F2 its not working...

No, if the file is created with F2, you won't encounter that error when running the debug script

 

Boot to the Clover screen. Press F2 and F4. Then continue booting into OSX

Now run the debug script
