@Jake Lo @Hervé Hi, good news! i got the touchpad working without any weird behaviours and discriminations. i used the VoodoooPS2Controller version found on my first post from github, which did the magic. i will attach it here should someone too facing similar problem on big sur could also try it. Here is my touchpad info when i used linux to check maybe it could help. I: Bus=0011 Vendor=0002 Product=0008 Version=0310 N: Name="AlpsPS/2 ALPS DualPoint TouchPad" P: Phys=isa0060/serio1/input0 S: Sysfs=/devices/platform/i8042/serio1/input/input6 U: Uniq= H: Handlers=mouse2 event9 B: PROP=9 B: EV=b B: KEY=e420 70000 0 0 0 0 B: ABS=260800001000003 E6430_Big_Sur_VoodooPS2Controller.kext.zip

i was able to locate it but i don't wanna mess anything there as i have no idea on where to begin and what to change. I will use wireless mouse it seems to be working perfectly. Thank you @jake lo @Hervéme too i don't know any touchpad that works that way. Thank you once again for your help

So basically with fingerZ i have to go down this road (attachment 1) There's no much settings in config.plist to adjust Voodoops2controller plugin voodoops2trackpad (attachment 2)

@Jake Lo @Hervé i tried the Dr. Hurt's Bronxteck compiled v6 from both link (they the same), guess what? it worked but with a strange or maybe not discriminations. Cursor won't move when i use my finger tips to control but moves when i use my "finger palm" or moves when my finger is horizontally positioned on the touchpad (how does the touchpad even knows which side of finger is controlling it?) Another weird or maybe not thing is, "two finger" gesture or tap does NOT discriminates. It works correctly no matter which side of the finger is controlling the touchpad. I tried going through accessibility maybe it could be some settings but nothing of such is in there. I mean of course i can manage and adapt to the "will" of the touchpad if there's no fix. Thank you.

@Hervé thanks for clarification on my Broadcom card, i have 2 intel alternative which is quite supported when i checked openintelwireless website. Please can you give me a link or search word to easily locate the version of voodooPS2controller you were referring? The EFI @Jake Lo made for me already contained the version of Dr Hurt's VoodooPS2Controller (see attachment) but not "compiled by Bronxteck". I went to several thread made by Bronxteck but couldn't locate it and also your E6230 thread.

@Jake Lo @Hervé Thank you, Olarila's big sur worked. I have some few issues or maybe some questions. After installation 1. My wireless is not working or perhaps not supported but bluetooth works perfectly (Broadcom BCM94313HMGB). Please is there a fix? 2. My touchpad kinda works but hardly, sometimes needs to touch it hard before responding and after few movement it stops. Something like not sensitive enough i guess and i try looking at settings maybe i could find something relating to sensitivity but nothing so i guess it is kext problem. 3. (Not all that important to me) Some of my apps overlaps the dock and its not resizable, is it a kext problem or apps problem? below is an attached screenshot. Thank you once again for your assistance.

@Jake Lo, @Hervé Hi, please after big sur download am facing an error when trying to create a bootable mac os x big sur drive. I have downloaded different big sur dmg (2) but i have the same error. 1. i used balena etcher on windows to create bootable then copied my efi folder, my laptop recognise it but no installer found on the bootloader. 2. used transmac to restore image but still wont recognised the installer on the drive only bootloader menu with no installer. 3 . i installed mac mojave and use the command to create the bootable drive but am facing an error which i don't know if my dmg files are corrupted or i need to install something to make it work. this is the command to create bootable i suppose sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled and this is my error temp$ sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled Password: dyld: Library not loaded: @executable_path/../Frameworks/IAESD.framework/Versions/A/IAESD Referenced from: /Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia Reason: no suitable image found.

Please anyone with a known working big sur dmg should help me out. thanks.

@Hervéyah i downloaded hackintoshShop distro but am now downloading non modified from apple. i will test it immediately i finish downloading.

i have re-upload previous images again @Jake Lo The LowRes config works. i am able to boot big sur now without any panic error but the graphics transition is bit slow or not smooth enough. Is there something i need to check to make it okay? i got error when i tried to install it. Could it be corrupt big sur dmg or opencoure error?

@Jake Lo I tried it by making the following changes A23 bios and 1366x768 resolution so i did the following in propertree on windows Deleted these from ACPI folder 1. DSDT-A24.aml 2. SSDT-i5-3320M.aml 3. SSDT-i7-3520M.aml 4. ssdtPRGen.sh and i updated the your original config.plist file not the LoRe.plist with changes made above 1. ACPI>ADD changed DSDT-A24.aml to DSDT-A23.aml 2. left SSDT-i5-3340M.aml as it is same as mine I didn't succeed in booting to the installer interface. Had some errors which i screenshot for debugging and to track down the error. I am attaching them in their order of occurrences and a log from OC. After failure on bios A23 i upgrade it A24 and reversed the changes made earlier but i faced the same error. But i noticed ACPI>DELETE you have "Drop CpuPm" and "Drop Cpu0Ist" set to "false" Anyway i love the bootloader theme 00:000 00:000 AAPL: #[EB|LOG:INIT] 2021-04-29T11:28:09 00:071 00:071 AAPL:

Hey my "Hope" , thank you very much i will try it as soon as possible and get you feed back.

thanks mate, but i have decided to give up after reading, testing and failing for days on all kinds of tutorials and EFI folders. At a point my hdd and modular bay stopped working. My laptop wont boot anymore with those things mentioned above connected and i flash BIOS versions again, finally downgrading it to A03 saved my ass. Am gonna cool down for awhile and wait for someone's already working EFI folder for my model or someone generously prepare one for me. I understand i am a total noob to this that's why everything seems difficult and always failing. Even catalina won't install. Thank you man for your help. NB: i spent several days on dortania without success

hey sorry for late reply, i was reading to equip myself with some basic as am very dumb. 1. i removed SSDT-PLUG from the acpi 2. replace VoodooHDA with latest AppleALC from here 3. i update the config with Plist Editor Pro <dict> <key>BundlePath</key> <string>AppleALC.kext</string> <key>Comment</key> <string></string> <key>Enabled</key> <true/> <key>ExecutablePath</key> <string>Contents/MacOS/AppleALC</string> <key>MaxKernel</key> <string></string> <key>MinKernel</key> <string></string> <key>PlistPath</key> <string>Contents/Info.plist</string> </dict> and disabled VoodooHDA. 4.Since am good on Capri something, i left it untouched Lastly i am confused of this "It's important that you get NVRAM working as this will ensure active/selected screen brightness is retained throughout reboots or sleep/wake cycles." How do i make the nvram working?

Thanks for the reply, how do i apply "Capri framebuffer + SSDT-PNLF" to my efi folder to solve the issue.? Do i need to generate SSDT-PNLF for my model as i did with SSDT-PM.aml? I don't mind much about touchpad as i use external mouse most of the time. Glad to know bios version is not that much of a problem as am free to upgrade back to A23. I know i sounds lame as am kind of new to hackintosh world.

Hi everyone am trying to install big sur on my laptop but currently using Mojave which is working perfectly with the exception of touchpad and Atheros AR9485WB-EG Wireless card. I followed this and downloaded EFI files for OC bootloader. i generated my SSDT.aml as instructed in the post and replaced it. The main problem is after OC verbrose screen, the backlight will go off immediately on the apple logo. The temporal workaround to bring the backlight back is "fn + arrow up" but it will go off randomly again and if i don't do that quickly the laptop will go to sleep and i will have restart the installer again. What i have tried so far; regenerated my own SSDT.aml tried latest whatevergreen and lilu kext tried flashing back and forth dell BIOS version Tried recommended bios settings from this site Tried Herve's EFI file in this post and touchpad is not working All didn't solve big sur backlight abnormality So my question is, is there a way to fix the backlight issue with a kext or drivers ? If am to stuck with mojave, is there a way to use whatever is making my touchpad working when booting big sur using EFI from here? Is there something am missing? Is there working EFI available for my model? Note: Mojave works with any bios version i flash regardless of warning to flash A12 Thanks everyone.
