@Jake Lo I may be talking nonsense but we agree that I need to keep these kexts enabled: -VoodooPS2Controller -VoodooPS2Controller.kext/Contents/PlugIns/VoodooInput -VoodooPS2Controller.kext/Contents/PlugIns/VoodooPS2Keyboard -VoodooI2C.kext/Contents/PlugIns/VoodooGPIO -VoodooI2C.kext/Contents/PlugIns/VoodooI2CServices -VoodooI2C -VoodooI2CHID And then, I install according to your advice?

Is there a specific order to install VoodooSMBus & VoodooRMI ?

I found this on github: https://github.com/VoodooSMBus/VoodooRMI Do you think it's related ?

Hi you all, Finally, I have succeeded in an installation that is not yet 100% but almost. Shout out to @Jake Lo & @Hervé for your precious advices & technical helps. The only thing that is still not working is the trackpad which is quite basic. As soon as I touch the trackpad, the pointer goes to the left. I have to use a second finger to select something and a second Tap to open something. I tried various kexts (VoodooI2CHID & VoodooI2CSynaptics) but still no real working trackpad. Maybe there are still errors in my config.plist. I think I'm about at the same point as @denkteich is with his configuration. I'll keep looking on my side. If you ever think of something while checking my files, I'm interested HackBook-Latitude-5510.ioreg config.plist.zip

@Hervé Yes I found a VoodooI2CSynaptics. Do I need to uninstall some kexts ? Or just add that VoodooI2CSynaptics ?

@ Hervé Thanxalot for the info. So I need to uninstall the VoodooI2C kexts ?

@Jake Lo I haven't found out what type of trackpad is on my Latitude 5510! I read on some forums that it could be a Synaptics. Is it possible?

@Hervé Yes I got the Tackpad PrefPan . I enabled, disable and re-enabled Tap to click just in case but it's not working properly. There are another SSDTs from @Jake Lo folder I didn't installed yet: -SSDT-GPRW.aml -SSDT-USB-Reset.aml Do you think I need to install it ? I'm gonna try just in case. I will learn from my own mistakes I also see that I have SSDT-XOSI.aml in my ACPI folder and it is not in Jake’s folder. I will try to uninstall it to see if it has any impact.

@Jake Lo I added SSDT-TPDX. Trackpad is working now but it's a bit strange. There is just the pointer who's moving but I can't select or open anything. I have to press the left button to select or open something. I added SSDT-BRT6 & SSDT SSDT-OCWork-dell from your EFI/ACPI folder too.

@Jake Lo ok thanx I deleted all the uncheck kexts. I tried to enable VoodooPS2mouse and trackpad but no diffrerence. Trackpad still not working. I'm gonna check what kind of touchpad is it I still hope to find a solution Thanxalot for your help by the way? All your advices have been are absolutely awesome. You rule !!!!

I'm new here and very happy to see a nice hackintoshing community. I started to make some hackintoshes in 2009 and i like it. Since I never quite hackintoshing. Hope it's not gonna disappear with the new ARM M1 chip. Cheers

@Jake Lo Yes I did. Maybe it's a dumb question but is it normal that some kexts are desactivated ?

I still can't solve the trackpad issue Any suggestions ?

@Jake Lo I made a new fresh install. I first installed Catalina with the OpenCore method. Then I upgraded directly to Big Sur with the AppStore. Then I used the EFI Latitude 5510 folder you posted. I had a compatibility concern with OpenRuntime r12, r11 was required. Then I remembered that @murkie posted different EFI.zip. I took the last one he posted. I mix with your files to find the good settings. After several tries, I managed to make an EFI file that works well. Everything works like a charm (Graphics, WIFI, Ethernet, Bluetooth, HDMI, Audio, Camera, Keyboard, Backlight, Hotkeys, Volume buttons, fn Key for brightness, Sleep/Wake). Only the trackpad does not work at all. It drives me crazy Ahahaha Latitude 5510 HackBookPro.ioreg config.plist.zip

Hello Jake, Yes I tried it in the 1st place but no trackpad with it I got WIFI, Ethernet, Audio who's working with your files but the headphone input works strangely. The sound is extremely saturated. Now I tried to add SSDT-DGPU but my screen stay black after Big Sur start to load.
