Thanks Hervé, your last advice worked, display stay alive without disconnecting HDMI

Hi Hervé, Some news with some progress. The system boot and I have now graphics acceleration but with some issues. At the boot end, the display goes black, come back with the login display ,and then goes black again and stay black. I must disconnect hdmi connector and reconnect it to get the display again and after it is running correctly with acceleration. Here joins are the new files Have you an idea ? Many thanks for help EFI.zip Vorke.ioreg

Yes DVMT i did this several times but i thought that Watevergreen was doing this now. I will try to apply these patches

Same result, black screen and reboot. I have only HDMI output on this Nuc so no possible to see change in IOReg. Do you think I can modify acpi tables in the bios like in the beginning to increase Vram ?

This miniPC has an hdmi output. It is using a mobile processor as the one i had i my previous Dell Latitude 5590. As you said, consequences are a slow running but without glitches.

Thanks for answer Hervé. I tried with : AAPL,ig-platform-id 00001259 and device-id 16590000, black screen and reboot again and again. If i remove device-id line and let only the first one, i can access the desktop. In fact, on the first line, i can put anything, it can boot, only the second line give me a black screen and reboot

Hi, I use a "simili Nuc" bought some years ago. I tried to install MacOS on it. I could do it, Ventura is booting and working partially, but not possible to activate video acceleration. Here are some characteristics, name is Vorke V2 : - intel equiped with a i5-8250u, 16 Go ram, network running, video running but with Intel Graphics 620 7mb displayed. OpenCore 0.9.8, kext and drivers removed. Many thanks for help. Regards Serge VorkeMAC.ioreg EFI.zip

Thank you for answer, I have seen a post on another forum talking aboute I2C I will try too post on it. My laptop is 90 % finished so I can now wait for a final solution. Your help greatly permitted to me to go forward Thanks Jake

Hi Jake, Very busy this week. I m quite sure keyboard is PS2 so all buttons are on a the same board as touchpad. Do you think I must try to re install High Sierra ? PS: Just tried, I had already installed high Sierra on an external same result, no buttons .. ?

Jake, I have been thinking about what you said concerning buttons driven in keyboard kext. I can boot this laptop windows 10. is there a window or dos program which would permit to give this answer ?

Hi Jake, I looked in windows touchpad id is \_SB.PCI0.I2C1.TPD1 I think touchpad include buttons (not part of keyboard)

Yes, click by tapping is ok and 2 fingers tap for right clic also ok.

Hi Jake, I discovered that the trackpad is working but not the buttons ! no action on clic. I mostly use mouse but in this case I used only trackpad with buttons I will try to analyse your patches (to try to understand ...) An idea ?

Hi Jake, Really, many thanks for all, that will be very helpfull for me. Very kind of you. I hope this post will be useful for somebody with 8th generation processors. Have a nice day.

Hi Jake, Again good news, slider is working. I think one file SSDT-PNLF or SSDT-ALS0 was corrupted. Compile it again, and all is working. I upgraded successfully to 10.13.6. Many thanks for help. PS : Please, what was the patches list you apply to my origin files ?

Hi, Solved for sound -> appleALC.kext, sound working up to 1.2.7 version, after, no sound hardware detected. Have you an idea Jake, for slider missing in monitor settings ?

Good news Jake, Trackpad is working great !! I just lose sound and I had to put back some files in clover/kext folder to make it work I will look which ones are mandatory. Your patched acpi files work, nice job. In monitor preferences, slider is not present. I am quite sure I saw it working.... so many manipulations, I can't remember what was done. Here are ioreg files. Thanks for all 5590_after.ioreg 5590_before.ioreg

Hi Jake, Thanks for answer, i will test after work

Hi Jake, Here are specs: Dell Latitude 5590 - Bios 1.3.2 (last) - Cpu i5-8250U - 16Go Ram (2 X 8Go) - Clover 4617 - High Sierra 10.13.4 installed on Sata SSD (not NVMe) - Graphics working except backlight cursor not presentDSDT and SSDT - Sound ALC3246 (working) - Network Intel I219-LM (Working) - Wifi DW1560 (Working) - Keyboard (Working) - Touchpad not working (i2c certainly) I would like to learn how to patch DSDT and SSDT files, I tried several times without success Hope this will help origin.zip CLOVER.zip

Hi Bronxteck, Thanks for your answer, i just started to work on this. I managed to boot it with clover but after 3 months practice about patching, i have not understood yet what are the mandatory patchs to apply on origin files (got with Clover F4) as quoted in your message "plus your standard laptop issues like back light, audio, WiFi, bt, track pad/keyboard (these might be on an i2c bus) sleep/wake/shutdown, power management" I applied patchs in clover boot (no acpi patching) but for example, to have trackpad running need to patch DSDT file, and i would like to apply the patchs in clover directly in acpi. I can attach Origin folder if needed. Many thanks for help

Hi everyone, Has somebody successfully installed High Sierra on a Dell 5590 (coffee Lake processor equiped i5-8250U) ? Regards

Ok thanks Jake, I started to practice patching using your advices. Many problems encountered were with the numerous syntax errors even if you try to recompile without modifying anything. For some of them, i don't know what to do (to remove) in the code ??

Hi Jake, I tested again with Sierra and High Sierra it crash. That is strange, everything changed when I installed a NVME in the laptop. Now everything is ok with the bootpack that I have posted previous post except touchpad. High Sierra is installed on a sata ssd. What patch is needed for touchpad ? Thanks for help

Tried just now, same crash.. Everything working except touchpad with files attached. An idea ?? Edit : I don't understand which patch or other needed for Touchpad, it doesn't come from kext because running under Sierra Working.zip

Sorry Jake i am not aware of all acronims. here is what i can see, all above is scrolling too quicly EDIT : Could you please post again clover folder complete i am not sure about all options in config.plist and all kexts. Thanks
