pspfreak Posted November 25, 2016 Share Posted November 25, 2016 I followed the guide from here: https://osxlatitude.com/index.php?/topic/9383-dell-e6220-i7-2620m-clover-detailed-guide/ My E6420 is the HD 3000, i7 2620m, 900p screen version. I can not for the life of me get past the dreaded still waiting for root device. I have made sure all my bios settings match the ones that are linked in the guide to no effect. I'm using a OS X Yosemite VM in VMWare workstation 12 on Windows 10 but that shouldn't matter too much, should it? I have tried boot flags such as -v -x, -v -x -s, those kind of things.

Administrators Bronxteck Posted November 26, 2016 Administrators Share Posted November 26, 2016 those last few lines look like its the ps2 trackpad initializing. try another version compatible with sierra. also what bios revision is the E6420 at? there are fixes for ahci detection at around a16. looks like a23 is latest one.

pspfreak Posted November 26, 2016 Author Share Posted November 26, 2016 I know its the latest, whatever was in 2016, just updated it a month or so ago unrelated to this. Maybe I could try taking the trac pad driver out for now, to see if thats the problem. Edit: This is what I have before the garbled text after removing the tracpad kext.

Administrators Bronxteck Posted November 26, 2016 Administrators Share Posted November 26, 2016 are you using a dsdt or ssdt from another model laptop? try booting with cpus=1 option Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 26, 2016 Moderators Share Posted November 26, 2016 The error is due to USB issue. Check you have AHCI enabled in BIOS again. Try leaving out the SSDT.aml Link to comment Share on other sites More sharing options...
pspfreak Posted November 26, 2016 Author Share Posted November 26, 2016 I had to remake the flash drive cause I messed it up, and now im further back.. no idea what i did.

Administrators Hervé Posted November 27, 2016 Administrators Share Posted November 27, 2016 KP due to vanilla AICPUPM kext... If you use Clover, enable the AsusAICPUPM patch. If you use Enoch, you should either use NullCPUPM kext or the pre-patched AICPUPM kext. You may refer to my E6220 guide (and pack). Link to comment Share on other sites More sharing options...

I'll try that but I just wanna ask, is the ssdt required for boot of the installer? Or can that be done afterwards Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 28, 2016 Moderators Share Posted November 28, 2016 Afterward is fine. Link to comment Share on other sites More sharing options...
pspfreak Posted November 28, 2016 Author Share Posted November 28, 2016 Good news.. kinda.. I got a lot further this time. I followed your guide Herve, minus the ssdt.aml. Now i'm getting stuck here. Link to comment Share on other sites More sharing options...
