tanya Posted December 3, 2020 Author Share Posted December 3, 2020 @jake Lo Thanks! your config did it: Working HDMI! Look at this! : from the left to the right: Dell Latitude 3400 - USB-C to HDMI convertor (ali-express 5 € ) - build in HDMI out A very useable system: above all expectations! Working: everything, except the Trackpad (and VGA-out, but I guess, that is impossible) @Jorge1964 You have to use the Opencore bootloader, not Clover. You can use this EFI.

Moderators Jake Lo Posted December 4, 2020 Moderators Share Posted December 4, 2020 This one looks like the old one, none of the fixes are applied, like the SMBios name and the HDMI patches. Are you sure this is the latest export? Link to comment Share on other sites More sharing options...
