Latitude E7470 Opencore Catalina 10.15.7 Post installation help


Recommended Posts

Hello, I have managed to install it on the hard drive but I'm having some problems still:

- Track-pad not working

- No Sound

- HDMI Out - When connecting an external monitor the internal display blanks and I loose all the control since the mouse and menus do not appear in the external monitor.

- Ethernet Adapter not working


Somethings that shouldn't work are working surprisingly:

- Wifi and Bluetooth


Dell Latitude E7470m Intel i5 6300, 8 Gb RAM, 256 SSD, Audio Realtek.


Any help is much appreciated.

For external HDMI video, close the lid for a second until external monitor becomes primary. Then open the lid.

or sleep the computer 1st, then wake it up. HDMI video will work correctly

If you have Intel wifi /BT, replace / add appropriate kexts which you seem to have already

I have removed  SMCDellSensor.kext but the laptop refused to start.

After Changing the Voodoo with the version advised also gave the same results.

So everything back to the same.

I have changed the layout ID to 11 and Audio was fixed. Thanks.

This one was also referred by Takobaba. Thank you all.
