With this 840 G3 works perfectly fine for BS 11.2.3, but cannot get updated to 11.4 (starts boot then reboots, never getting to GUI)

That is OC 0.6.6 (I suppose it must be updated to 0.6.9 for 11.4, but never got round to it yet) (even OC 0.6.5 is OK for 11.4)

edit:

In the end I simply gave up on this update

Instead used full 11.4 USB installer (with same OC 0.6.8 EFI) and upgrade/update worked perfectly fine

Did you ever have trackpad buttons (left/right) working?

As I can no longer edit post no 1 attached is fully working Clover folder for Optiplex 3046 SFF

CLOVER.zip

Thanks, audio with above works, also added in config

                <dict>
                    <key>Comment</key>
                    <string>change _DSM to XDSM</string>
                    <key>Find</key>
                    <data>X0RTTQ==</data>
                    <key>Replace</key>
                    <data>WERTTQ==</data>
                </dict>

this machine uses H110 chipset so created ssdt-lpc (using MaciASL)

DefinitionBlock ("", "SSDT", 1, " ", "SSDT-LPC", 0x00003000)
{
    Method (_SB.PCI0.LPCB._DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
    {
        If (LEqual (Arg2, Zero))
        {
            Return (Buffer (One)
            {
                 0x03                                        
            })
        }

        Return (Package (0x02)
        {
            "compatible",
            "pci8086,9cc1"
        })
    }
}

, so AlppleLPC loads,

kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc

Adjusted USBs using [Guide] Creating a Custom SSDT for USBInjectAll.kext

 

All works as good as one could expect

HDAUDIO\FUNC_01&VEN_10EC&DEV_0255&SUBSYS_1028079B&REV_1000

 

-> i.e. Realtek ALC255

Using DP works all the way.

Boots fine from HD

Ofcourse audio does not work, and I will want to make proper dsdt edits, but that is a good start

 

Thanks for help

Without USBInjectAll.kext it is exactly the same, stuck on "Waiting on boot-uuid-media"

 

With USBInjectAll.kext gets stuck on this with HDMI connection:

 

 

I realized that at this point is swaps the display to DP, so with both cables connected it installed OK

 

Sepster

I have tried this config, sadly it made no difference to the outcome

 

 

I can get a bit further using USBInjectAll.kext but then I get KP

 

 

 

 

 

Trying to install High Sierra on Optiplex 3046

I can not even get to installer screen due to waiting on boot-uuid-media

 

USB2 stick in any of the (back or front) USB ports

 

 

Original ACPI attached.

Help appreciated

Fully working steps:

1. Clover is attached

2. Used config from this post

3. Needed Lilu.kext & IntelGraphicsDVMTFixup.kext as recommended in this post and USBInjectAll.kext to be able to boot installer

4. Audio works with AppleALC.kext as per this post

5. Post install bits are in this post
