ssprod Posted April 21, 2016 Share Posted April 21, 2016 Greetings! E6420-i7 2640m-Nvs4200M Using this guide (https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-el-capitan-clover-guide/&do=findComment&comment=54621)combined with the specific DSDT for the gpu, my new monkey is running extremely well, great performance after i generated a specific SSDT+Jakes DSDT ( E6420_Nvs4200M = E6420 + DSDT.aml.zip), however with Optimus Enabled, it will not output to HDMI and it is my understanding that it won't be possible. With Optimus disabled,I have tried Jake's "DSDT-NVS.aml" (https://osxlatitude.com/index.php?/topic/7478-dell-latitude-e6xxxe7xxx-yosemite-install-guide/) as well as Wern's (http://www.insanelymac.com/forum/files/file/342-latitude-e6420-nvs-4200-dsdtaml/?st=10#commentsStart) but both hold at GeForce Sensors, then render a black screen. Any assistance would be most appreciated. Thanks very much! Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 21, 2016 Moderators Share Posted April 21, 2016 Try switching smbios to MBA6,2 with Wern's DSDT. Link to comment Share on other sites More sharing options...

ssprod Posted April 21, 2016 Author Share Posted April 21, 2016 Thanks for the assistance, Jake.. With your suggestion, Wern's DSDT with my original EFI and modified smbios gets me to boot w/ Optimus disabled, but i've lost USB and still no HDMI video. I've attached Werns DSDT, my SSDT and original .config. Archive.zipFetching info... Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 21, 2016 Moderators Share Posted April 21, 2016 Try Wern's Config file Link to comment Share on other sites More sharing options...
ssprod Posted April 21, 2016 Author Share Posted April 21, 2016 Same result, no HDMI, no USB. Just to note, I've installed Clover @ Legacy, noticed he's referring @ UEFI mode. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 21, 2016 Moderators Share Posted April 21, 2016 With Wern's Config, are you able to boot to Desktop with the smbios MBP8,2? Link to comment Share on other sites More sharing options...
ssprod Posted April 21, 2016 Author Share Posted April 21, 2016 Jake, yes indeed. Both 8,2 and 6,2 boot to the desktop. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 21, 2016 Moderators Share Posted April 21, 2016 try this. Modded Wern's config with USB patches. For HDMI, do you mean video or audio? HDMI video should work with Optimus disabled. config.plist.zipFetching info... Link to comment Share on other sites More sharing options...
ssprod Posted April 21, 2016 Author Share Posted April 21, 2016 Sorry Jake, still no USB or HDMI Video. The HDMI monitor powers on when the system boots, however the message "monitor is going to sleep" flashes every 10 seconds. I'm using the last config. and Wern's DSDT. Please see attached. Optimus is not checked in the bios. Bios version A22. Thanks for your efforts. dsdt+config+kexts.zipFetching info... Link to comment Share on other sites More sharing options...
