Actually, I have asked the kexts' dev and he said that that kexts don't work on Ivy Bridge and older, I don't why, he said that he haven't get his kexts working on any Ivy Bridge/older system

Sorry, that look doesn't good, do you mind trying this, then: https://github.com/VoodooSMBus/VoodooRMI/pull/38

No, I have make a issue to kexts's developer and he said that the kexts have some problems with the RMISMBus with Ivy Bridge and older CPUs. how about you, did you manage to make that kext work with OpenCore by disabling VoodooPS2Mouse, Trackpad and did you try this before: You could try using an SSDT to set _STA to zero for that PS2 device? Not entirely sure that'd work. It would make it dissapear I think from the IOService plane at least. DefinitionBlock(/* I forget all this */) External (\_SB.LPCB.PS2M, DeviceObj) // This may not be the exact path to PS2M Scope (\_SB.LPCB.PS2M) { // or whatever the path is If (_OSI("Darwin")) { _STA = 0x00 } } } Another alternative you could try doing is changing _HID to be something other than a PS2 device, using something similar to above. I'm gonna test this on my end I guess, and see what I come up with. That said, I've not needed to do something like this, all I've needed to do is prevent VoodooPS2Mouse/VoodooPS2Trackpad from loading. Setting Enabled to false for those in the Config.plist is enough The link is here: https://github.com/VoodooSMBus/VoodooRMI/pull/38#issuecomment-669643309

Did you try disable the VodooPS2Mouse and Trackpad before and did you try this then: https://github.com/VoodooSMBus/VoodooRMI/pull/38#issuecomment-669643309. Sorry for asking too much

OK, Enable 2 quirks is fixed. This problem is quite weird then, in the BIOS do't have CFG and I've asked a DELL Experts for this but funny that just keep spamming crazy message. Anyway, thanks

My laptop is Ivy Bridge so do I need SSDT-Plug then? I've used the [ssdtPRGen.sh](https://github.com/Piker-Alpha/ssdtPRGen.sh) Thanks

Well, In my BIOS as you give me (Thanks for this!) show my laptop doesn't have CFG Lock so I have tried to disable AppleCpuPmCfgLock for AppleIntelPowerManagement.kext and AppleXcpmCfgLock for the Kernel(XNU) and I have received this issue. I don't know if this is another problem beside CFG-Lock-related issues so I want to ask here for helping from some kindly guide to help me fix other errors (not CFG Lock)

I've done the SSDT-EC here: Results.rar ACPI.rar

@Hervé I did do that (my DSDT have _STA method), SSDT-EC I mean. Here is my ACPI and my DSDT.aml if you want ACPI.rar Results.rar

I'm using OpenCore 0.5.9 to install MacOS 10.15.5 on my laptop DELL INSPIRON 3421 but I'm stuck in at this. Can anyone help me. I also include the pictures as well as some log for better troubleshooting. Thanks for reading my mes sage opencore-2020-08-02-112415.rar

I’ve tried to used the VoodooRMI.kext, VoodooSMBus.kext (from here: https://github.com/VoodooSMBus/VoodooRMI) but my synaptic trackpad didn’t work (Even I’ve tried disable VoodooPS2Mouse,Trackpad and then VoodooInput inside VoodooPS2 as wel, it can’t moved). I had used the troubleshoot page, too. As you see, there aren’t any SMBus-related SSDT and I’ve modified the VoodooSMBus.kext, too. Here is my EFI as well if you want. Thanks a lot for reading my message. P/S: I also tried to add these patch from here: https://github.com/leo-labs/macOS-ThinkPad-T480s/blob/EFI.zipmaster/EFI/CLOVER/config.example.plist#L500-L535 but my mouse still can’t move

@Jake LoThanks a lot for trying to help me. I think the best way now is to contact DELL as soon as possible (I've just sent them a message for that, may be help). By the way, how could you extract my BIOS then, I've tried but didn't work, even I've tried the newest version from here: https://github.com/LongSoft/Universal-IFR-Extractor/releases.

@Jake LoHere is my ROM file then: Fixing CFG Lock.zip
