zekica2 Posted February 12, 2018 Share Posted February 12, 2018 I'm trying to install High Sierra on Dell Latitude E5450 Intel i5-5300 with HD Graphics 5500 (no dedicated GPU) The Bios Version A07 SATA SSD (Samsung EVO 850) that is in AHCI mode I have tried using bootpack from: https://osxlatitude.com/index.php?/topic/10207-e5450-fresh-install-high-sierra-and-few-problems/ But I'm stuck at "Still waiting for root device" (the attached screen is exactly before the message). Here are the "origin" AML files (from my system) and the clover folder (removed binaries but kept all info.plist for kexts to fit in 2MB). Clover version is rev 4330 (UEFI mode). BIOS DVMT is set to 64MB (using the utility that I can't remember the name since I set it up for Sierra) I even tried cloning the USB stick (install partition) to the SSD and booting from there, but the same happens. What am I doing wrong? Thank you in advance. Note: I had Sierra successfully installed on this laptop, and I have High Sierra successfully installed on another E5470 with Skylake booting with the same Clover version. e5450-origin.zip e5450-clover.zip Link to comment Share on other sites More sharing options...

Administrators Bronxteck Posted February 13, 2018 Administrators Share Posted February 13, 2018 looks like you need to drop a oem ssdt table or need the fixheaders patch Link to comment Share on other sites More sharing options...
zekica2 Posted February 13, 2018 Author Share Posted February 13, 2018 FixHeaders was already enabled, but FixRegions wasn't. The installer now boots correctly. I'll mark the topic as solved once I install the OS. Link to comment Share on other sites More sharing options...
zekica2 Posted February 13, 2018 Author Share Posted February 13, 2018 Thank you for your help! I have managed to make everything work (except WIFI, but that's ok). Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted February 13, 2018 Administrators Share Posted February 13, 2018 if your wifi is intel based then it needs to be replaced as there is no native support for them in osx Link to comment Share on other sites More sharing options...
