My Dell Inspiron 14 3421 specs: BIOS: A13 Chipset: Intel HM76 RAM: 4GB DDR3 CPU: Dual-Core Intel Core i5-3337U (Ivy Bridge) @1.8GHz GPU: Intel HD 4000 Display: 14" LCD, 1366 x 768, LVDS Audio: Realtek ALC282 TouchPad: Synaptics Wifi+BT: Dell Wireless 1704 Ethernet: Realtek PCIe FE Family Controller Bootloader: OpenCore 0.6.0 ## What work? * USB 3.0 * Audio (layout id=3) * Ethernet * Keyboard and Synaptics mouse (Brightness Hotkey, used to be breakless and the fix is updated to the troubleshooting page) * DVMT Pre-Allocated 32MB (WEG manual) * Webcam * NVRAM (emulated) ## What don't work? * Dell Wireless 1704 (need replace) * iService (need to call Apple) * SD card My EFI is here on Github: EFI Thanks for reading my article.

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

It now can read my BIOS it now and make a backup (although there is a problem in the parse: "FileHeader: file alignment 10h is greater than parent volume alignment 8h") but I still can't find CFG Lock and I've tried to extract it into a readable file but didn't work, too.

@Jake Lo I've tried this before and I've receive this error:

@Jake LoSorry for that, I've run in cmd this: path/to/O14A13.exe /writeromfile and then the extracted file is here (It also contain the O14A13.exe): CFG Lock.zip

My laptop does have CFG Lock, though. I've tried running VerifyMSRE2.efi but it has shown that my laptop has registered MSRx0E2 protection so it does have that kind of Lock but I can't find CFG Lock in the BIOS image

Is there any way to unlock the CFG-Lock in my laptop, DELL INSPIRON 3421. My BIOS is O14A13 (link: https://www.dell.com/support/home/en-vn/drivers/driversdetails?driverid=dcgmv&oscode=wt64a&productcode=inspiron-14-3421). I've try using the /writeromfile but when open the file with UEFITool (link: https://github.com/LongSoft/UEFITool/releases) but when open it, it shown some errors and when I find the word "CFG-Lock", it shown no things although I can find the Unicode string "CFG". Thanks a lot for reading my article and helping me. For the turning off CFG-Lock guide that I'm using is here: https://dortania.github.io/OpenCore-Post-Install/misc/msr-lock.html#what-is-cfg-lock

@Hervé, @DiogoSilva48, I've found a newer kext here: https://github.com/VoodooSMBus, it still in beta and I don't know if it work for PS2Elan. Anyway, it is a hope, too.

I've installed MacOS Catalina 10.15.5 with OC 0.5.9 DEBUG on my DELL INSPIRON 3421. Although I've used VoodooInput, VoodooPS2controller (by dortarnia) and ApplePS2SmartTouchPad (from) but I couldn't tap with 3 fingers (1,2 fingers are work well but not 3,4,5 fingers). Are there any way to solve this. Many thanks. Loc’s MacBook Pro.zip Config.zip

That it. I've finally fix it. Thanks a lot and by the way, do you care if I share this post with other people who have the same issue as me

I'm using Opencore (OC) 0.5.9 DEBUG version for installing hackintosh in my DELL INSPIRON 3421. Although the VRAM=1536mb and the display is default for scaled, there’re still lots of noise, stripes on the screen so I’ve surfed the net for a way to solve this headache maker problem and finally, I’ve found one on this group (the link is here: https://osxlatitude.com/forums/topic/11004-e6230-upgrade-to-mojave-has-anyone-had-success/page/2/?tab=comments#comment-90011) , although it’s for Clover config.plist but I’ve put them in OC config.plist (Kernel->Patch) but didn’t solve it. Is there any help to make it work correctly My DELL INSPIRON specs is here: BIOS: A13 RAM: 4GB DDR3 CPU : Dual-Core Intel i5-3337U, 1,80GHz Graphic: Intel HD Graphics 4000 Monitor: 14" LCD 1366 x 768, connector LVDS Audio: Realtek ALC282 Wifi card: DW1704 Broadcom 802.11n LAN: Realtek PCIe FE Family Controller Here is some picture about my problem as well as my config.plist (sorry that I’ve delete the platforminfo because it has my real MAC address) Thanks a lot Config.rar Videos.rar
