Select AddDTGP in Clover Configuration ACPI section
Look at your ioreg, you have two PNLF. You patched the DSDT, remove all the following (from DSDT):
Ok I fixed all that thanks to you
I tried to change AAPL,ig-platform-id and device-id as suggested
Values were 00009B3E and 9B3E0000
I changed to 0000A03E and A03E0000
Then it boots but with unaccelerated graphics and 7MB memory
Is that corrrect ? Should I change something else in the properties ?
So I kept current platform/device id then i tried your proposal for SMBIOS/platform
0x3EA50004 with MacBookPro15,2 SMBIOS = black screen
0x3EA50005 with MacBookPro15,2 SMBIOS= black screen
0x3EA50009 with MacBookPro15,2 SMBIOS = OK ! but still grey screen after sleep
or
0x3E9B0000 with MacBookPro15,1 SMBIOS = OK ! but still grey screen after sleep
0x3E9B0006 with MacBookPro14,1 SMBIOS= black screen
0x3E9B0007 with MacBookPro14,1 SMBIOS= black screen
For those tries I just changed for the graphics (example) :
<key>ig-platform-id</key>
<string>0x3E9B0007</string>
Should I change something in pci devices properties too ?
or try to follow some guides about black screen after boot on mojave (I read about some patching with hackintool, but not sure it will help to solve my case ...)
Now I am lost ... what should i try ?
hopefully you are there
