My computer uses a few days normally then suddenly in clover does not show mojave partition.
All other partitions of windows are displayed normally.
My mojave partition is apfs format.
I have been like that 3 times already.
When I use the r driver to restore the mojave partition, it will return to normal in the clover.
This issue made me lose many important files and took a lot of effort to restore.
Please help me solve this problem!

Do R-Driver. It breaks the map parition of the hard drive. If you want to backup, use a time machine or carbon copy for safety. Don't waste your time researching or hiring a service that searches some r-driver files. All types of sida he thought to install 1 machine that brought through the computer as well as any machine should upload to share as right.

Quite typical on (Dell?) Haswell laptops. My E6440 does the same. There is no fix that I know of...

I have try this way on my young brother's M4800 :

-> Copy your EFI to USB

-> add VoodooHDA to Kext/Others of clover on USB

-> Boot with clover of USB to macOS

-> Play some video with audio

-> remove USB of your computer

-> restart and boot to macOS (It's will boot from your hard driver EFI)

-> tada.... audio work again.

let's try it and show me your results

p/s: audio always losing after panic or after restart from windows.

i have replace M4800 with Clevo P775DM3-G (i7 7700k desktop + 1080).

sorry.

Hi, I have managed to get my g751jl laptop working with El Capitan. Everything that I care about working is working except for the Thunderbolt port. This is a bigger issue for me as I was going to use it in a recording studio with Logic but I can't connect any firewire soundcards using Apple's thunderbolt to firewire adapter as it seems that thunderbolt is not working. I'd prefer not to spend $1000 on high end USB soundcard and use what I have. Plus I'd like to be able to take the laptop into any recording studio, use Logic and plug it in to what they have there. For this I need the thunderbolt port working on my Asus g751 otherwise I'd need a real mac.

 

Has anyone managed to get thunderbolt working in OS X on their g751?

 

I read that setting BIOS to thunderbolt 'legacy' mode is recommended to work in OS X but the BIOS of the g751 does not have that option. Is there any other way to get thunderbolt working? It is intel thunderbolt.

dear sir!

can you share your vBIOS dump by Clover (Press F6 to save graphics firmware into /EFI/CLOVER/misc)

thanks

 

If you suspect a CMOS reset by the OS, there are 2 things you can try:

 

1) patch your DSDT RTC device from:

       Device (RTC)
       {
           Name (_HID, EisaId ("PNP0B00"))  // _HID: Hardware ID
           Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings
           {
               IO (Decode16,
                   0x0070,             // Range Minimum
                   0x0070,             // Range Maximum
                   0x01,               // Alignment
                   0x02,               // Length          ---> Set to 2 by default
                   )
           })
       }

to:

       Device (RTC)
       {
           Name (_HID, EisaId ("PNP0B00"))  // _HID: Hardware ID
           Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings
           {
               IO (Decode16,
                   0x0070,             // Range Minimum
                   0x0070,             // Range Maximum
                   0x01,               // Alignment
                   0x08,               // Length          ---> Changed to 8
                   )
           })
       }

2) Install the pre-patched AppleRTC kext

 

You may try either/or as well as both at the same time but it may not fix your issue.

 

Alternative to DSDT RTC direct patching:

with the current BIOS you get an option to select through which graphics card external ports(HDMI/mDP) are connected discreet or internal.

 

have tested with both modes. you can have the external display connected through intel hd530 also.

wow, please check your system by Aida64 and tell about your Internal Information (Monitor Name, Monitor ID, Manufacturer)

here 's example : 

linux is failing on this case, bro.
linux is not good at all. 
you must check with VBIOS to known it

Hi guy!

Today i will talk about M4800.

Multi-Prototype:

May be all people don't know or don't care: "M4800 have 2 prototype of Motherboard" <--- it's the dead point that i discovery. 

Prototype 1: Dell Motherboard LVDS TRPM M4800 (full lucky):

+ use LVDS for internal Display (with max resolusion is Full HD)

+ can disable Switch Graphics (run only Quadro/Firepro) full performance, full external port.

+ if don't want Quardo/Firepro can run with optimus.

---> Replace Wifi + upgrade WWAN/mSata SSD ----> a monster of Workstation Mobile.

Prototype 2: Dell Motherboard EDP TRPM M4800:

+ use eDP for internal Display - eDP full HD / HD+ (not so lucky):

+ can not disable Switch Graphics. (black screen)

+ cannot export sigal to HDMI/DP/VGA

+ internal Display use intelHD 4600

+ Quadro/Firepro can use for any Software use Cuda/OpenGL for render/editor. (can disable Quadro/Firepro by DSDT).

---> Replace wifi + upgrade WWAN/mSata SSD ----> a monstar too ( but smaller than Prototype 1).

i'm not sure but may be Prototype 3 for 4K display use DP (don't have intelHD4600):

+ use DP for internal Display - that may be good if can inject monitor by some key or may be bad because don't have intelHD 4600

How check:

Use Ubuntu Live:

command is: Xrandr

<image updating>

Check VBIOS

<image updating>

Use Aida64 report

<image updating>

Prototype 1: install OSX very very easy.

Prototype 2 (is my M4800): very very easy with enable Switch Graphics. (not talk about it).

let's talking about disbale Switch Graphics! - big issuse with black screen.

.... updating......

next day i will update more. ...

more image, more infomation, and more about same hardware (M6800, Zbook 15 Dream Color, 8570w Dream Corlor, ROG 120Hz 3D screen ... ).

thanks for watching.

not work on my hardware. 

something wrong.
give your linux iso file, i will check my system.
 
upload your Aida64 report hardare.
 
here you are : only nvidia (disable optimus)

 
and here is some image when open my Display by tourvis
 

 

If "Switchable Graphis" options in BIOS is Enabled, your display is connected via eDP and use Intel HD4600 GPU.

If "Switchable Graphis" options in BIOS is Disabled, your display is connected via LVDS and use nVidia Quadro GPU.

Please check it, if you have the same results

wrong!

M4800 only one internal port on mother board. not dual port. 

it about hardware not software.

kOn,

 

No I haven't got it working yet.

The nVidia card is Quadro K1100M

The Laptop display is connected via eDP not LVDS and is QHD+ 3840x2160.

 

What I've tried.

Followed guides to completely disable the nVidia card (patch DSDT, SSDT), but this completely knocks out the display as soon as DSDT loads I didn't try the EDID injection with this, but I believe this is not worth trying.

 

Now I want to go full nVidia, but I feel I need to inject more info into the DSDT to get this thing working right.

If I take the laptop apart and remove the display connector then I get the Optimus setting in the BIOS. but as soon as I plug the Display back onto the motherboard, it goes back to only using nVidia.

it about NVCAP

a Hope for eDP : Asus G750 (only GTX770m , no have optimus ) use eDP port for internal Display.

Default all
 
Sata is AHCI
 
enable optimus
 

All file you need on My current Signature

 

Here are the results from

xrandr --listproviders

 

Providers: number : 1

Provider 0: id: 0x2d9 cap: 0x1, Source Output crtcs: 4 outputs: 8 associated providers: 0 name:NVIDIA-0

 

Here are the results from

xrandr

 

Screen 0: minimum 8 x 8, current 3840 x 2160, maximum 16384 x 16384

VGA-0 disconnected (normal left inverted right x axis y axis)

DP-0 disconnected (normal left inverted right x axis y axis)

DP-1 disconnected (normal left inverted right x axis y axis)

DP-2 disconnected (normal left inverted right x axis y axis)

DP-3 disconnected (normal left inverted right x axis y axis)

DP-4 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 346mm x 194mm

   3840x2160      60.0*+   48.0  

DP-5 disconnected (normal left inverted right x axis y axis)

DP-6 disconnected (normal left inverted right x axis y axis)

 

+ xrandr --listproviders say DP-4 connect to your internal display

+ Can  eDP  support with QHD+ display ? I don't think so.

Why QHD+ system do not have intelHD (optimus enable):

+ intel HD 4600 can not support with QHD+ resolusion -> the main reason for Dell disable optimus.

+ nvidia K1100M can support with 4 display 4k 

i sure your system easyer more than my system because Real Mac not support with eDP ( only support with LVDS, HDMI, DP, DVI ).

my connector is eDP :

+ rampage's method inject for desktop not for mobile
+ research "aapl boot-display"
* read more on isanelymac.

your internal Display connect at DP4
research more about inject nVidia to DSDT.
set boot-display-port = 4 
use SMBIOS imac 14.2

+ Clover all time
+ Can you see "Build-in-display" on Brightness slide bar ? (no external display)
 
issue is your internal display's connector type.
 
run live Ubuntu 
-> open terminal
-> type : xrandr --listproviders
-> enter 
--> copy all result to here.
 
i hope your result don't have eDP port.
