Could be your PS2 controller kext; which one are you using?

Calm down please! And no-one has accused you of any sort of misbehaviour, quite the contrary in fact... The method remains the same, only the PS2K notification values change, that's all. Which is why I wrote "this kind of patch"... In fact, you should be able to refine your patch by further experimenting with it in order to establish which of the 3 x values of each set (10/206/286 & 20/205/285) actually apply to your Inspiron model. I'm pretty sure only 1 of the 3 applies and you would actually find that the BRT6 SSDT provided by Jake also works once you apply the appropriate notification values. Getting the correct keystroke codes is the key here, hence why I linked to the original post/thread where it is clearly mentioned. Nothing else to it and certainly nothing dark or nasty behind my post.

We have known, detailed and used this kind of brightness keys patch for many years on laptops such as the E6xxx or E7xxx series... But thanks for this particular useful contribution for the Inspiron 5570. https://osxlatitude.com/forums/topic/8285-refined-alps-touchpad-driver/?do=findComment&comment=84779 https://osxlatitude.com/forums/topic/8285-refined-alps-touchpad-driver/?do=findComment&comment=84815 https://osxlatitude.com/forums/topic/12129-latitude-e7250-with-i5-5300u-hd5500-and-1366x768-lcd-high-sierramojavecatalina/?do=findComment&comment=93508

Seems OP is using a distro... -> "HackintoshShop.com". @truceFR We don't support distros here, far too much trouble. Please download a genuine Big Sur installation package off Apple/AppStore and follow the numerous guides we've got here for these E6x30 models.

Ice Lake computers are only supported from Catalina, so don't waste your time trying to install High Sierra on yours. See our OS X/macOS section if you need further details on general support specs. Don't use any old version of Clover either (r511x/r512x minimum).

It's as I thought: you're using the CPU power management SSDT not suitable for your i5-3340M but made for a quad-core i7-3630QM. I suggest you grab the i5-3340M SSDT I had posted in my bootpack, rename it to "SSDT-PM.aml" and replace your current invalid table by it. You should also only use 1 (one) x SSDT "EC" table; you've placed 2 (two) in your ACPI folder.

I see you've got SSDT-BRT6.aml installed. Things may depend on the PS2 controller kext you're using.

Simple matter of removing all those erroneous lines of "Zero"... DSDT.dsl.zip

I would not use some of the contents of my E6230 bootpacks on an E6430 with nVidia GPU. BIOS differnsubstantially so patched DSDT ofE6230 does not really apply. Then, there is the matter of graphics and screen resolution. E6230 is LoRes 1366x768 and therefore uses LoRes Capri frame buffer layout 0x01660003. That's not useable on systems with higher res. So, post your system's specs and a (zipped) copy of the EFI folder you're using. An indication of the bootloader you're using and its version would be very useful too. There's a good chance you've not applied the correct CPU power management settings but that's just a guess.

Did you update your OC config to reflect the change of SSDT PNLF table, then reset NVRAM before rebooting?

Clover config of the pack contains disabled settings for DW1820A wireless card. Enable or remove as appropriate. Caching add-on kexts from /L/E is faster than injecting them from E/C/k/O. After any kexts modification, whether to /S/L/E or to /L/E, repair permissions and rebuild cache. Edit: 17 Jan 2024 Revised bootpack with modified SSDT-GPRW patched ACPI table to fix intermittent loss of Bluetooth on wake.

For proper 4K output, patching BIOS to set DVMT pre-allocated memory to 64MB or 96MB is mandatory. Boot a USB key with ModGrubShell installed on it as explained here and set variable 0x432 to 0x02 or 0x3: setup_var 0x432 0x3 exit Default value is 0x1 for 32MB (0x2 is 64MB, 0x03 is 96MB). Once the change is applied, no need to inject patched Framebuffer memory settings (fbmem/stolenmem) as properties in your bootloader's config. Bear in mind that this DVMT adjustment can be removed by resetting BIOS to default settings.

Ok about the nVidia dGPU. Re: brightness control: Yes, SSDT-PNLF table from Dortania's OpenCore site Yes, keep the GFX0 to IGPU renaming in your OC config (it appears to be in place already) Yes, replace any PNLF table in ACPI folder by the one obtained from Dortania's site; if you open it up with maciASL, it should refer to GFX0, not IGPU.

I don't think you should be using that SSDT-PNLFCFL on a Haswell laptop. Given that you rename GFX0 to iGPU in your OC config, I'd have used the regular SSDT-PNLF table, as is, i.e. with references to GFX0. NB: I note that you've not disabled the nVidia dGPU; is that normal?

Brightness control restored in 11.3 on my E6230 after removing device PNLF from the patched DSDT (it was a very old patch of mine) and adding SSDT-PNLF table (from Dortania). @draskostar watch out with your ACPI settings with regards to iGPU: if you have renamed GFX0 to IGPU in your patched DSDT rather than through bootloader's ACPI device renaming, you'll also have to rename GFX0 to IGPU in SSDT-PNLF too.

That's one of them (Slice's). I use this one (old versions by Rehabman forked off Kozlek's work): https://bitbucket.org/RehabMan/os-x-fakesmc-kozlek/downloads/

Maybe VirtualSMC and its sensors are not appropriate for iStats Menus app; you could try to switch to FakeSMC and its sensor PlugIns to compare behaviour. I've just tried v5.32 on my old C2D Vostro200 desktop (all my Hacks run with FakeSMC) and the usual CPU, thermal or other fan and SSD sensors were reported and shown.

Must be a local error on your side; just tried from a Win10 PC with Edge and no issues at all. Whether logged in or not.

Lost brightness control too on my E6230. I have PNLF device built into the patched DSDT; it was something I had added years and years ago; need to remove that and opt for SSDT-PNLF table as posted on, say, Dortania. This may fix the brightness issue.

@Sadhiq please try and use the forum Search facility in the future... Thank you.

@Leonardo.schellenberg Mieze just posted a new version v2.4.2. https://www.insanelymac.com/forum/topic/287161-new-driver-for-realtek-rtl8111/page/63/?tab=comments#comment-2756300

Try and follow the Dortania documentation for OpenCore: https://dortania.github.io/OpenCore-Post-Install/#how-to-follow-this-guide https://dortania.github.io/OpenCore-Post-Install/misc/nvram.html#cleaning-out-the-clover-gunk

ACPI tables: You already have the SSDT-PNLF in your OC ACPI folder, so all is covered. You need to remove SSDT-PLUG though and disable it in your OC config. Graphics/Capri framebuffer properties: All suitable/necessary properties are already injected in your patched DSDT (see _DSM Method under IGPU device). Kexts: Remove VoodooHDA and replace with AppleALC (its' a Lilu plugin). Audio will then work with alcid 12. You shouldn't use USBInjectAll alongside USBPorts. Latter is usually generated having initially booted with the former. So try without USBInjectAll to begin with. I invite you to consult my E6230 guides for details of the kexts I've used and what they do. Versioning is also detailed in case you need to update those that may be old. It's important that you get NVRAM working as this will ensure active/selected screen brightness is retained throughout reboots or sleep/wake cycles.

Backlight should work OOB with the right settings in place: Capri framebuffer usual patching + SSDT-PNLF. TouchPad should also work OOB with the VoodooPS2Controller available in my E6230 guides; the kext works 100% in all E6x30 models of the range. Maybe yours is faulty or possibly disconnected; check that out. Latest BIOS are Ok to use for sure as long as you apply the FBMem patch that reduces memory from 16MB to 8MB (glitchy graphics otherwise).
