rykerza Posted October 17, 2014 Share Posted October 17, 2014 Hi, I've been desperately trying in vain, to get Yosemite to install on my Dell E5540.My Specs: Dell E5540 with I5-4310U @2GHz8GB RAM Intel HD4400 with Nvidia Gforce GT720MIntel Ethernet I218-LM Network Card(I've disabled the un-suported Intel WIFI)AHCI is Enabled for SATA I've followed the below guide to no avail (along with other guides in the forums) https://osxlatitude.com/index.php?/topic/6461-guide-e7440-with-clover/&do=findComment&comment=36589 Not once have I been able to get to the Installation screen. Could someone please enlighten me as to what I'm doing wrong... (With Mavericks I tried the patched Mach_Kernel for 10.9.4 which also resulted in a continuous boot loop) I've attached my EFI Folder along with the modified DSDT.aml file.All Im looking to do, is to get LAN / Sound & Video working on Yosemite.

makzinations Posted October 19, 2014 Share Posted October 19, 2014 i updated a few files and your config. i did not touch your acpi folder. You sir, you are a genius! I'm not commenting a lot on all forums but your zip package worked instantly without any modifications on my Latitude E5540 without GTX graphics card. I never got any version (DP, Beta, GM or even the Final) of Yosemite to get into the installer. THANKS A LOT!!!! Link to comment Share on other sites More sharing options...
rykerza Posted October 19, 2014 Author Share Posted October 19, 2014 @ BronxtechThank you for your help, however I'm unfortunately not as lucky as makzinations.Mine is still ending in a reboot loop.I added the -v option behind the ones already set and took a photo where it reboots.I set the Bios to defaults (except for SATA which is set to AHCI and VT-d is disabled)The screenshot is attached... Am I missing something? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted October 19, 2014 Administrators Share Posted October 19, 2014 no I'm not sure. maybe you guys need to compare bios versions also i see i2c do you have a touch screen? Link to comment Share on other sites More sharing options...

Administrators Bronxteck Posted October 19, 2014 Administrators Share Posted October 19, 2014 try adding the nvidia to your config plist using clover configurator. or you need to turn off optimus in bios or in your dsdt. Link to comment Share on other sites More sharing options...
rykerza Posted October 21, 2014 Author Share Posted October 21, 2014 @ BronxteckThat did the trick! Thank you so much for all your help! =)I've attached my working EFI folder for anyone else who would like it!I now just need to figure out how to get sound & VGA display out working and I'll be a happy man!*UpdateSound is now working using VoodooHDA-v2.8.6 installer pkg, however no sound out through headphone jack (anybody know how to fix this?)No VGA output yet though... anyone know of a edited kext for HD4400 to allow display to a 2nd monitor?
