Well, may be it's not supported in modern versions of macOS.

Sorted with following SNB patch: 01 02 04 00 10 07 00 00 10 07 00 00 // vanilla: nb of connectors -> "04" 05 03 00 00 02 00 00 00 30 00 00 00 // vanilla: laptop's own LCD display 02 05 00 00 00 08 00 00 05 00 00 00 // patched: HDMI, display port #5 (built-in port) 03 04 00 00 00 04 00 00 06 00 00 00 // patched: DP, display port #6 (docking-station port) 04 06 00 00 00 04 00 00 07 00 00 00 // patched: DVI, display port #7 (docking-station port)

Further to additional tests with forum member MikeGiff, the following SNB framebuffer patch supports direct DP output (tested out of docking station to DP screen): 03 04 00 00 00 04 00 00 06 00 00 00 The tests were validated with combinations of dual-screens setups: built-in LCD + DP built-in LCD + DVI DVI + DP 01 02 04 00 10 07 00 00 10 07 00 00 // vanilla: nb of connectors -> "04" 05 03 00 00 02 00 00 00 30 00 00 00 // vanilla: laptop's own LCD display 02 05 00 00 00 08 00 00 05 00 00 00 // patched: HDMI, display port #5 (built-in port) 03 04 00 00 00 04 00 00 06 00 00 00 // patched: DP, display port #6 (docking-station port) 04 06 00 00 00 04 00 00 07 00 00 00 // patched: DVI, display port #7 (docking-station port)

You'll have to find the correct settings for the Radeon HD5450 then. At least, it's properly detected so it should work. Oh, I think I know where you got your stuff from... http://www.insanelymac.com/forum/topic/312656-guide-macos-sierra-1012-dell-optiplex-780-760-755-790/

Try this one instead: config.plist.zip If it does not work, use latest Clover Configurator v4.55 to edit the config file and try the various AMD5000Controller offered. Remember to save the config file after each change.

Try this DSDT. DSDT.aml.zip Basically, I've moved the GFX0 device that was injected/declared under PCI0.PEG0 (i.e. a PCIe slot) to PCI0.CPI4, i.e. the PCI slot under which the card registers in IOReg. Let me know how it goes. Try the different AMD5000Controller FBs as/if required. Don't hesitate to post a zipped/compressed copy of your EFI Clover folder too so that we can check the Clover config too.

I don't think you read anything past my initial questions on X3000 accelerator kext in my previous answer.

Your IOReg screenshot shows exactly what you had to look for; so the card is seen and that's good news. You said you tried all the framebuffer settings but what about the card id in the accelerator kext? Was it already there? It not, did you add it? The thing is your DSDT contains what appears to be a valid patch for an HD5450 card and the patch fakes dev id 1002:68E0, i.e is the default one supported by the accelerator kext as shown below (extract of 10.13's X3000 accelerator kext): <key>AMDCedarGraphicsAccelerator</key> <dict> <key>ATIEnableWideBlitSupport</key> <true/> <key>ATIUseTearingWideBlit</key> <false/> <key>CFBundleIdentifier</key> <string>com.apple.kext.AMDRadeonX3000</string> <key>GpuDebugPolicy</key> <integer>0</integer> <key>IOClass</key> <string>AMDCedarGraphicsAccelerator</string> <key>IODVDBundleName</key> <string>AMDRadeonVADriver</string> <key>IOKitDebug</key> <integer>0</integer> <key>IOMatchCategory</key> <string>IOAccelerator</string> <key>IOPCIMatch</key> <string>0x68E01002</string> <key>IOProbeScore</key> <integer>200</integer> <key>IOProviderClass</key> <string>IOPCIDevice</string> <key>IOSourceVersion</key> <string>0.0.0.0.0</string> <key>IOVARendererID</key> <integer>16908288</integer> </dict> ` However, the DSDT patch is inserted in device PCI0.PEG0.GFX0. This can only work if it matches your IOReg device and I've got a feeling it does not... Save the output of IORegistryExplorer, zip it and attach it here so that we can check things out and adjust the DSDT patch if necessary. By the way, which version of OS X/macOS are you running?

It's because you inject those through the Clover EFI folder, not cache them through /L/E (or /S/L/E) which is better... This being said, there's nothing to worry about.

HD3000 only supports 2 x concurrent displays, not 3. As such, you can get dual external displays if and only if the lid is closed. Once you've applied the appropriate SNB framebuffer patches, all will work.

I'll have to verify that, it's been a while since I last played with this...

APFS is very slow on mechanical HDD only. Ok on SSD...

RE: post #24, trying to declare device 413c:8158 compatible with device 413c:8143 through your envisaged code... <key>413c_8143</key> <dict> [....] <key>CFBundleIdentifier</key> <string>com.apple.iokit.BroadcomBluetooth20703USBTransport</string> <key>CFBundleIdentifier - 2</key> <string>com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport</string> <key>IOClass</key> <string>BroadcomBluetooth20703USBTransport</string> <key>IOClass - 2</key> <string>BroadcomBluetoothHostControllerUSBTransport</string> <key>IOProviderClass</key> <string>IOUSBHostDevice</string> <key>IOProviderClass - 2</key> <string>IOUSBHostInterface</string> [...] <key>idProduct</key> <integer>33091</integer> <key>idVendor</key> <integer>16700</integer> <key>Compatible-idProduct</key> <integer>16868</integer> <key>Compatible-idVendor</key> <integer>17201</integer> [...] </dict> ... well, hmm... would be quite exotic and -of course- completely, how to say this?, wacky! Did just simply make that up? Kexts and kexts patching are no cocktails in which you add/mix ingredients and then shake, you know. So, no that would not be the way to go. Why? Well, because: the way it's written, it would attempt to declare device 413c:8143 (i.e. DW1550 BT module) compatible with device 413c:8158, i.e. the other way around. it would try to refer to 2 x separate kexts (BroadcomBluetooth20703USBTransport + BroadcomBluetoothHostControllerUSBTransport) it would try to declare multiple same parameters in series (CFBundleIdentifier & -2, IOClass & -2, IOProviderClass & -2) it would try to declare invented parameters (Compatible-idVendor and Compatible-idProduct) What you need to do to inject your device was explained several years ago in post #4 of this thread or here in my E6220 guide. As it happens, you already have all the necessary information to do this. The patch does not even have to be made to the Bluetooth transport kext itself but can be injected in FakeSMC in the same fashion tat was described here for AGPM tuning for instance. If your module is a BCM2070x device, you may need to apply Rehabman's firmware patches too, though I did not see yours in there list. But it's quite an old device after all...

Your grep command filters for a kext containing "Fake" in its name... Is it the case for the names of the PlugIns? PlugIns are kexts just like any other driver. You should see them loaded (or not) in your SysProfiler->Software->Extensions section. But rest assured that they are loaded or HWMonitor would not show the info it currently does. If you see no GPU entry in the T° section of HWMonitor at any time, even after waking the laptop, it's pretty safe to say your nVidia dGPU is fully disabled; permanently.

First of all, check whether it's seen in IOReg with IORegistryExplorer. If it is, it should normally just be a matter of injecting the correct device id in the accelerator kext AMDRadeonX3000 kext ff it's missing there and calling on the correct ATI/AMD frame buffer (should be one of the AMD5000Controller family). Can all be done through Clover Configurator if you run Clover. You'll need to set "Inject ATI" of course.

You can use HWMonitor app (calls on FakeSMC Plugins) to verify if nVidia GPU remains turned off after wake from sleep. In SSDT-12, it's most definitely turned off at startup through the _INI method of device SB.PCI0.RP05.PEGP: Method (_INI, 0, NotSerialized) // _INI: Initialize { Store (Zero, \_SB.PCI0.RP05.PEGP._ADR) _OFF () } I've not seen calls to turn it On or Off after wake in the DSDT.

Check the IOGraphicsFamily patch in Clover's config file with CloverConfigurator tool, section Kernel & Kext Patches. It should be: Find: 01007525 Replace by: 010000EB25 and your config file may have the patch details of a previous OS X version in place.

There's a good chance your system returned to default hibernation mode #3. Check this with pmset -g Terminal command, then follow the FAQ tuto on disabling hibernation. Unless you set laptop to support hibernation with Clover, you need to revert to plain old sleep mode. https://osxlatitude.com/index.php?/forum/161-faqs-tutorials/

Either you remove the patch you made or you re-install a backup you took.

It's disabled, so you can clearly remove it... But that will not make any difference.

HD4000 ??? You're very mistaken. That's Ivy Bridge integrated graphics... You stated it yourself: you have HD4400 graphics, i.e. one of Intel's Haswell iGPU. You're meant to use Azul Layout #12 (layout-id 0x0a260006) and fake desktop HD4600 is 0412.

Those issues and limitations are already clearly posted on Chunnann's original thread at InsanelyMac (see from post #21); let's not unnecessarily duplicate info here, it's best to report issues to Chunnann directly in at IM. The above facility is a mere adaptation of Chunnann's work posted here. For the record, only AR946x cards appear to run at decent speeds to date. NB: Re: macOS versions, you obviously meant 10.13 and 10.12 (not 10.3 and 10.2)

No fix to date.

You should look at the E6540_Optimus pack in that case. The pack posted for the E5440 is for Intel graphics only.

Check the FAQ section re: supported wireless cards.

Waterwolf, it's be useful (for you) if you would read the existing guides for that laptop model, where absolutely everything is detailed and available. Really everything. Your Clover configuration is a bit messy: You have no compiled SSDT table for your CPU in the ACPI/patched folder, only a source text file... As such, do not expect to have any proper CPU power management at all. If you read Pike R Alpha's blog, you should be able to generate the table properly, especially as the script does ask you all the right questions... Your Clover config.plist points specifically to several ssdt files that do not exist! ssdt.aml + ssdt-0.aml + ssdt-1.aml + ssdt2.aml. Your Clover config.plist has unnecessary options selected in its Boot section, but never mind, they don't do any harm. In the Kernel & Kext Patches section, you can remove the KernelPm patch, it's useless on Sandy/IvyBridge; you only need the AppleIntelCPUPM patch. You can keep the AppleRTC patch if you want of course. You have the correct IDT 92HD93 AppleHDA patches in the Kernel & Kext Patches (as confirmed by JakeLo); consequently, I cannot understand your post #24; late night mistake probably... Your kexts folder is quite wrong; for instance, you've copied the FakePCIID_XHCIMux kext but missed the parent kext FakePCIID without which the former will simply not work. For some obscure reasons, you've posted that you've installed VoodooSDHC kext. This is a big mistake for at least 2 reasons: it causes issues with sleep & wake your DSDT already has the patch to make the O2 card reader work OOB (though the injected info differs a bit from the patch we usually apply) So, if you want your E6230 to work well, the 1st thing to do is to generate the compiled SSDT table for CPU Power Management and adjust your Clover config.plist accordingly (Drop DMAR + SSDT CPUPm + SSDT CPU01st and remove those useless SSDT entries in Sorted Order). Wrong: Correct: If the SD card reader does not work OOB, adjust the patch in the DSDT from this: Return (Package (0x08) { "compatible", Buffer (0x0D) { "pci14e4,16bc" }, "name", Buffer (0x0D) { "pci14e4,16bc" }, "model", Buffer (0x18) { "O2 Micro SD Card Reader" }, "IOName", "pci14e4,16bc" }) to this: Return (Package () { "compatible", Buffer (0x0D) { "pci14e4,16bc" }, "model", Buffer (0x18) { "O2 Micro SD Card Reader" } }) as described in the reference thread on the matter posted here.
