andradejose Posted March 23, 2018 Share Posted March 23, 2018 Hi, I had a fully working HS setup but all of a sudden it stopped working. I am in the process of re-installing Mac OSX. I lost the USB drive used for the initial install so I created a new one following what guides available here. I have used the latest Clover (4411), latest Lilu.kext, latest IntelGraphicsDVMTFixup.kext, and generic Sierra EFI and the Bootpacks E7470_1.17.5_HS.zip OR E7470_1.17.5_HS-alternate.zip at no avail. The installation freezes, I have attached my compressed EFI and a picture of the frozen screen for your review. Thanks. EFI.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 23, 2018 Moderators Share Posted March 23, 2018 Try updating BIOS to 1.17.5. If that still doesn't work, then export new DSDT/SSDT for patching. Link to comment Share on other sites More sharing options...
andradejose Posted March 23, 2018 Author Share Posted March 23, 2018 Unfortunately, I won't be able to update the BIOS. How do I export DSDT/SSDT? Link to comment Share on other sites More sharing options...
andradejose Posted March 23, 2018 Author Share Posted March 23, 2018 I have attached a screenshot of the KP of the broken HS install. I believe my wife might have updated to the latest HS version causing it to stop working. Any chance that installation is still salvageable? It says multiple times "EAPDFix: Failed to find Audio device HDEF" Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 23, 2018 Moderators Share Posted March 23, 2018 Try going into Options when you see the Clover loader, use the right arrow to navigate Select ACPI patching-> Tables Dropping-> Go all the way down and deselect Drop all OEM SSDT Check all the Drop "SSDT-xx" below that Select Return Change DSDT name: BIOS.aml or anything other than DSDT.aml Select Return, Return Hit spacebar to select Verbose mode + debug 0x100 mode See if you could boot with those settings To extract DSDT/SSDT, boot with the USB installer. When you see the Clover screen, hit F4. Only takes a second, all done in silent in the background. Compress and attach /EFI/Clover/ACPI/Origin folder from the USB installer Link to comment Share on other sites More sharing options...
andradejose Posted March 23, 2018 Author Share Posted March 23, 2018 Wow, you first advise got me back into my desktop in HS. Now the Audio, screen brightness control, Bluetooth and WiFi are not working anymore. I won't be attempting a new install. I would rather try to get the current install fully functional again. Can you please advise how to get them working? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 23, 2018 Moderators Share Posted March 23, 2018 Right, all that are not working because you bypassed all the patches done with the DSDT/SSDT. Try repairing permission and rebuild cache and then reboot. Link to comment Share on other sites More sharing options...
andradejose Posted March 23, 2018 Author Share Posted March 23, 2018 I repaired permissions, rebuilt cache and rebooted. Still getting Kp with same error "EAPDFix: Failed to find Audio device HDEF". I have attached the /EFI/Clover/ACPI/Origin folder if needed. origin.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 23, 2018 Moderators Share Posted March 23, 2018 Try this, boot back to system, replace the Config.plist and DSDT/SSDT to /EFI/Clover/ACPI/Patched. Make sure to remove and not merge E7470_andradejose.zip Link to comment Share on other sites More sharing options...
andradejose Posted March 23, 2018 Author Share Posted March 23, 2018 Replaced filed, repaired permissions, rebuilt cache and rebooted. Still get a KP. I am not able to boot using the "ACPI patching-> Tables Dropping->etc" option. I was able to replace the Config.plist and DSDT/SSDT with the original ones, I can now boot with "ACPI patching-> Tables Dropping->etc" option.
