roniez Posted April 5, 2017 Share Posted April 5, 2017 Hello.I am attempting to install macOS Sierra on my e7450 with discrete nvidia 840 and intel 5500 as per guide:https://osxlatitude.com/index.php?/topic/8514-dell-latitude-e7450-clover-uefi-only/It's refering to changing the DVMT in the guide to ensure windows reports 96mb. Mine currently reports 128, bios reports 64and using setup_var 0x15b in uefi shell shows that it is set to 0x03. I get the Prohibitory symbol on boot after using the stick that was created. A15 Bios version.And wondering if anybody could have any idea on what i am doing wrong.Kind RegardsRoniez Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 5, 2017 Administrators Share Posted April 5, 2017 Since Optimus (dual GPU) is not suported on Hackintposhes, I'd say you need to disable Optimus in your BIOS to run only off the iGPU. Then boot in verbose mode to see where the system hangs (if it still does). Link to comment Share on other sites More sharing options...
roniez Posted April 5, 2017 Author Share Posted April 5, 2017 Unfortuently i dont have an option to disable the nvidia card (optimus within the bios settings) Does anybody know of a bios version that allows this or if there is anyway to disable it with uefi shell?

Moderators Jake Lo Posted April 5, 2017 Moderators Share Posted April 5, 2017 The discrete will need to be disabled by DSDT patching. The file from my guide is for HD5500 only. Boot to Clover, hit F4. Compress and attach the Origin folder found in /EFI/Clover/ACPI. Also for DVMT, you need both 0x15b ad 0x15c set to 0x3, NOT just 0x15b Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted April 5, 2017 Administrators Share Posted April 5, 2017 if you used sierra 10.12.4 to make your installer make sure to download latest clover as well any clover below 4049 will not boot it correctly. Link to comment Share on other sites More sharing options...
roniez Posted April 7, 2017 Author Share Posted April 7, 2017 I am using the latest macOS installer from appstore, I will have the compressed Origin folder uploaded today, was travelling for a few days. EDIT: Redone the usb installer and now it worked fine, did not need to disable optimus in bios (not possible) did not need to patch the DST to disable it (might have occured manuallly) Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 7, 2017 Moderators Share Posted April 7, 2017 Should still patch DSDT to disable the discrete card otherwise it'll drain up your battery. If you look under Graphics/Display in System Info, you should see both graphics card loaded, even though the discrete is not being use. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted April 7, 2017 Moderators Share Posted April 7, 2017 As you can see, the discrete is loaded as Display which is draining your battery. Boot to Clover, hit F4. Compress and attach the Origin folder found in /EFI/Clover/ACPI. Please include the version of BIOS you're exporting this from. Link to comment Share on other sites More sharing options...
roniez Posted April 7, 2017 Author Share Posted April 7, 2017 i booted to clover and hit F4 but nothing happend so i rebooted back in to OSX and used EFI mounter and compressed the origin folder from there. hope it is sufficent. https://1drv.ms/u/s!ApOJpGp8IGHR8wbkbp2e6Yr9E9RS Dell Bios: A15 Clover: Latest Avalible Link to comment Share on other sites More sharing options...
