Hi, I'm gona to install newest MacOS Sierra on my M4800, so I appreciative your any knowledges and advices, which will be helpful. Thanks

For those, who have problem with audio after update OSX to 10.11.4, those files and patches are needed (for Dell Precision M4800/M6800): Needed kexts to S/L/E: AppleHDA.kext (must be original from 10.11.4, without patches!)

Hi, new problem is here after update to 10.11.4 on m4800. Audio is not working with newest AppleHDA.kext.

Yes, that's the problem in precision m4800 and m6800 and also in other laptops with optimus. So If I want to use external monitor with this laptop under OSX, LCD screen on laptop has full brightness and it can't be reduced.

Hi, At 1st: to get full Intel HD4600 performance on my dell m4800, I must install to S/L/E FakePCIID and FakePCIID_Intel_HD_Graphics, and also ig-platform-id 0xa260006 At 2nd: modify Azul FB to enable HDMI or DP output, but I tried several modify this framework and HDMI or DP still doesn't work.

no, the display brightness can not be reduced, if you have Nvidia Optimus disabled in BIOS and OSX runs with Nvidia Quadro only. I have the same problem with Nvidia Quadro K1100M on Dell Precision M4800. But if I enable Nvidia Optimus, OSX runs on Intel HD4600, the brightness can be reduced usin keys FN+F3 I think, but GPU performance is very poor and HDMI or DisplayPort doesn't work, so I can't use larger external LCD monitor.

What about sound? Is it working normally on your M6800?

Hi, I have the same problem, but not every time. Maybe properly DSDT patch can do make it work, f.e. delete other batteries in DSDT.

Could somebody upload VBIOS for Nvidia Quadro K2100M from Dell Precision M4800? You can use app GPU-Z in Windows to obtain VBIOS file. Many thanks.

Just one patch is needed I think. What aboud SSDT for GPU nVidia? It is necesary to patch this SSDT to disable discrete GPU, some _OFF method? Because if I enable "Switchable Graphics" in BIOS, system boots and run on Intel HD4600, but in About this Mac I see 2 GPU: intel and nvidia too.

Ok, could you check my files? FakePCIID is from this link and it is latest version 2015-1229 (Release) AppleIntelFramebufferAzul.kext is pateched with HexEditor intel HD4600, HDMI.zip

Ok and do you try it on El Capitan 10.11?

OK, I need some advice or help with it. I try to explain my steps, which I done: 1) Install kexts to S/L/E: FakePCIID.kext, FakePCIID_Intel_HD_Graphics.kext, FakePCIID_Intel_HDMI_Audio.kext 2) add 0x04128086 to FakeID->IntelGFX (into config.plist) 3) add binary patch for AppleIntelFramebufferAzul to KextPatches (into config.plist) Result: - Laptop display works with full GPU Intel HD4600 (1536MB), it's recognized properly as internal display 15,5" (1920x1080) - Backlight is at highest level and it can't be reduced by keys FN+Down, FN+F3 - Audio doesn't work - Video HDMI or DP output doesn't work

Can I add this patch under Kext patched section in Clover config.plist? Kext to patch: AppleIntelFramebufferAzul Find: 01050900 00040000 87000000 Replace: 01051200 00080000 87000000

If I try to wake up on battery power, it goes to hibernate mode I think and from this mode laptop can't be wake up. I must cancel hibernate mode during boot in Clover. If I try to wake up on AC power adapter, wake up works normally.

I tried this method day last day. I got full GPU with Intel HD4600, but with this method I lost HDMI and DP video output and I needed it, because usually work on external 24"LCD display.

Of course that HDMIAudio.kext is needed. I upload new attachement M4800 v.2.zip

problems may be with this: 1: my SSDT.aml is for CPU i7-4800mq, yours is i7-4810mq I think, so try it without this file 2: to work my wifi Dell Wireless 1550 I must insert device and vendor ID to Info.Plist here: /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contents and handOff+5GHz support with this wireless_bcm9435-110-v4.0c.command 3: your display, it is LCD TN, or IPS? wireless_bcm94352-110-v4.0c.command.zip

Sleep doesn't work properly. Closing LID doesn't work. Only button Fn+sleep works or apple logo+sleep (left corner at top). But system Fans is still running, screens go to black. Wakeup works and also HDMI works after wakeup. USB 3.0 (2x on the left + 2x on right side) work and also eSata port works and it is recognized as USB 3.0 port. USB 2.0 work too, but these ports are internal, for BT... You need DSDT patch for USB 3.0 + needed kext to works in 10.11 El. Capitan. I post all files later. Update: there are needed files for Precision M4800: - config.plist for Clover - patched ACPI DSDT.aml, SSDT.aml for CPU - kexts for Clover (10.10, 10.11) - kexts to S/L/E (AppleHDA is vanilla without any patches, version 272.51.3 from OSX 10.11.2) BIOS: load default configuration, SATA set to AHCI. - Switchable graphic Disabled - internal display brightness is at highest level and can not be changed (need resolve this problem), nVidia Quadro K1100M full GPU performance + HDMI, DP output, - Switchable graphic Enabled - internal display with changeable brightness level (Fn+Up/Down key), but with poor GPU performance. HDMI, DP output works with full GPU performance. LOOK AT THIS THREAD

Without 3 kexts I got Nvidia Graphics. Ok I will try your files from M6800 and post result. P. S. Your photo in link is from M4800, not from M6800. M6800 is 17,3", so it must have wider borders on the left/right side Update #1: After installing HDMIAudio.kext, my sound from internal speaker or headphone jack stopped work. And now only from HDMI output works (connected Sony TV via DP) So then I checked your DSDT from M6800 and my from M4800. Its are very similar, so I start make sound working again. I checked HDAU and HDEF in your DSDT and correct in my DSDT. Then I remove every used kexts for sound, removed every patches in Clover config file used for AppleHDA and AppleHDA_ALC292. Then I install yours kext AppleHDA, CodecCommander and HDMIAudio again and voila, SOUND WORKS!!! Internal speaker, headphone jack and also HDMI output. So I would like to THANK YOU.

I tried it and also with additional kexts FakePCIID, FakePCIID_Intel_HD_Graphics and FakePCIID_Intel_HDMI_Audio installed in S/L/E. Result: Internal display works on Intel HD 4600 (1536MB) with better performance + sound works too. But HDMI or DP output doesn't work. I have 24" Dell Monitor and 42"TV Sony. Any of them doesn't work. When I removed these 3 kext mentioned above, HDMI and DP ports works, also together, so I have 3 display connected (internal display, 24" LCD and 42" TV) but with sound from internal speaker or from headphones.

Yes, but I make sound working with clover patches for AppleHDA and AppleHDA_ALC292 + installing needed kexts to S/L/E: AppleHDA_ALC292.kext CodecCommander.kext EAPDFix.kext

Ou realy? I think 2nd DSM method has been added after appling patch. Because before patch I found only one. Ok, I try to figure out and use orher needed kext to resolve my problem.

Now I use newer patch and B0D3 is renamed to HDAU without errors. But nothing with HDMI/DP sound output changed. Still work sound from internal speakers or from headphones. Could you check it? acpi patched.zip
