Would you please share your opencore efi. I have Xeon E5 to and cannot get big sur installers to but. Not even preinstalled big sur boots. Please?

I have the lenovo S30 which has ALC662v3 but AppleALC nor voodooHDA works. Anyone care to share his/hers EFI-folder?

Does your Audio work? Care to share Clover.folder?

Would you mind posting your EFI-folder for this setup as I have S30 to?

No nothing installed there. Thought it was good meassure. The install is all vanilla.

Thanks Pavo!! ;) it booted just fine of my Usb so I put it on the disk and rebuild cache and permissions. Only DP works with DP-audio. HDMI is dead and if I put in a connection there to a screen the computer locks up. HDEF is in ioreg but missing in Sound prefs. HDEF and HDMI didn't work with...

Actualy I think the ssdt-patch i wrote about here will do it... #100 Anyways here is the debug.zip ioreg: ioreg-after-my-patch.ioreg Is it possible to add the rename NPE7.display@0 to NPE7.GFX2 from Original_SSDT-2.aml and add the same rename to...

Thanks for helping. I tried it but no dice I saw it is actually there (HDEF) but not in Audio prefs. I posted in the other thread.

Wonderfull I will have a read through it. Thanks for pointing it out!

I have the same problem. I see from your ioreg that you also need to rename NPE3.display@0 to something like NPE3.GFX2 for it to work with MacNB SSDT. I added some info in this thread... #100

Problems with HDEF audio device not working/non visible. Show up in IOReg tho. 1. Audio device HDEF is visible in IOReg but not in system information nor in audio pref so it cannot be used. 2. Mojave 10.14.2 / Lenovo S30 4352 / BIOS 60A / E5-1620V2 / Sapphire RX 580 Nitro+ 3. Used Toledo HDEF...

I cannot get HDMI working on Sapphire RX580 Nitro+. Got both DP working including Audio. But as soon as I connect HDMI system locks up. If I have the HDMI in when starting up it works but the screen connected to HDMI is just blank (although it stays on so it gets some kind of signal). The odd...

I tried using SSDT and also the Lilu.kext and Applealc.kext. The dreaded ALC662v2 doesn't show up. I tried the long thread of Realtek https://www.tonymacx86.com/threads/applehda-realtek-audio-guide.234732/ but it doesn't explicitly say anything about C602/X79 more than I seems to not be natively...

Hello, I think the clover files are in my debug.zip in the bottom of the third post. I used T480 DSDT to get HDMI working and it is in the debug.zip. I havent come any further since then, the big problem is the elantech touchpad.

Would you mind sharing your S30 clover folder? SimplyRyan and jim2046?

@ryanejohnson Could you share your clover folder for the S30?

With the kernelxcpm it reboots right after the first 15 textrows of the bootprocess where all the dots are.

I need help getting powerManagement and USB 3.0 working. I have Lenovo Thinkstation S30 with AMD 7750 and 128GB ram running fine except that USB 3.0 does not work and powerManagement seems off. CPU is always running at 1.2 Ghz which is way below normal base of 3.7Ghz. Turbo I never seen it use...

OK. Haven't really found anything working. What did you have in mind? Seems the ones out there is old. Maybe the particular model is not supported.

Most things are working now. Except for the touchpad which is new Elantech supposedly on PS/2. It says no touchpad attached and no multi gesture working not even scroll. I attached new debugfiles. I cannot get an ID for the device. In windows it seems to be attached to PS/2 but still no dev ID...
