To disable Nvidia Card (Easy Way)

 

you can simply use this DSDT Patch:

https://github.com/Ramalama2/UX301_DSDT/blob/master/6.%20Experimental/DSDT%20Patches/%5BALL%5D%20Nvidia%20PowerOff.txt

 

Cheers :-)

 

Great patch but i can't make a clean original DSDT of her laptop... If you can.. ?

Hey, do you think that your patch is compatible or can be modified to work on my dsdt? I have a Nvidia GTX 765m and a Intel HD4600

 

DSDT https://www.dropbox.com/s/vx30qnw4l270qcc/DSDT.aml

IOREG https://www.dropbox.com/s/4rffijvra3verdw/XMG%20C702.ioreg

 
Is it important that I create my DSDT with AIDA64, or can I create my DSDT with DSDT Editor on Mac?
I use Clover v.2330.

 

 

can you reupload your ioreg and give me a clean (vanilla) dsdt+(all)ssdt's?

I got some Problems.
 
First is, I don't find the option "ACPI Tools" on Windows 8.1 at the actual AIDA64 Version. But I have found a older Version 3.20.2600 and there ist the option "ACPI Tools".
The Program says that my Motherboard was not found or is Unkown.
 
Second is, that when I use the old Version of AIDA64 in ACPI Tool and click on Save Table I see 7 Lists of SSDT.
Which one you need?
 
 
Should I upload all?
 
Here is a Zip with all SSDT 1 to 7 from up to down and the actual DSDT.

What is your right laptop ?


You can also use Clover because it can patch your DSDT on the fly, no problem with asl errors ^^

And with clover, you can get iMessage natively (i have see your post and it is a big problem with chameleon :()

I use already the latest Clover...how can I use it on the fly?

 

My Laptop is a XMG C703 similar as MSI GS70.

How did you get iMessage natively?

iCloud worked and so on, but iMessage show me a notification, that I must contact the support...

Disassemble them correctly:

# in Terminal, with recent iasl
iasl -da *.bin *.aml
These patches for DSDT:

into method label ADBG replace_content begin //nothing end;
Remove all the lines 'Zero' starting at line ~6258.

 

You then have a DSDT which will compile with no errors.

 

Hi, RehabMan:

Can you help me for similar modification of my DSDT and SSDT to disable Nvidia Optimus GTX 880M ?

I have tried in vain by DSDT Editor or IASL due to too many errors.

My laptop is Asus G750JZ and Audio is Realtek AL-282 with working Speaker output now.

If possible I need HDMI audio for internal Intel HD4600 too.

I have got these DSDT & 7 SSDT with AIDA64 Business version 4.30

If you disassemble correctly, and use ACPI 5.0, your DSDT compiles almost error free. (remove all the 'Zero' lines, remove Arg0 line causing second error)

Hi, RehabMan:

Thanks for your help.

Following your advice there are 3 errors remained in my DSDT.dsl

Can you help me to correct these errors ?

Because I need error-free to get the final DSDT.aml

You did not disassemble correcty... with SSDTs as context. Place all OEM SSDTs and DSDT in a single directory and disassemble with 'iasl -da *'

I'm facing a problem with Optimus turned off. When I restart my computer, it shuts down. I know that this is due the Optimus being turned off and I need to turn it on inside the PTS method. My problem is that I have disabled the card using a SSDT. I don't know how to turn it on from a SSDT or calling an external method from a SSDT during PTS and WAK. Can someone help me turn on the card from SSDT? Thanks.

We do the same thing on the ProBook. You use an External declaration to gain access to the methods in SSDT from DSDT. These are the DSDT patches we use:

into definitionblock code_regex . insert
begin
External(\_SB_.PCI0.PEGP.DGFX._OFF, MethodObj)\n
External(\_SB_.PCI0.PEGP.DGFX._ON, MethodObj)\n
end;

into method label _PTS code_regex ([\s\S]*) replace_matched
begin
If (CondRefOf(\\_SB_.PCI0.PEGP.DGFX._ON)) { \\_SB_.PCI0.PEGP.DGFX._ON() }\n
%1
end;

into method label _WAK code_regex (Return\s+\(.*) replace_matched
begin
If (CondRefOf(\\_SB_.PCI0.PEGP.DGFX._OFF)) { \\_SB_.PCI0.PEGP.DGFX._OFF() }\n
%1
end;
The paths to _ON/_OFF may be different in your SSDT, so be sure to tweak the patch as necessary.

I'm not even touching the DSDT but only adding _DSM methods and other things that I need in a SSDT which is injected by Clover (DSDT free Clover config). The _PTS and _WAK methods do not exist in the SSDT where I have turned off the card. Can I reference to the _PTS and _ WAK in the SSDT? How? And will that overwrite the methods with the ones defined in DSDT? Thanks again.

 

My SSDT is similar to this one as decribed by Stevo here

DefinitionBlock ("SSDT-1.aml", "SSDT", 2, "APPLE ", "Optimus", 0x00001000)
{
    External (\_SB_.PCI0.PEG0, DeviceObj)

    {
        Method (_INI, 0, NotSerialized)
        {

            }
        }
    }
}

 

OK, pretty weird way to do it, and some strange code you have there (the 'if (1)' is especially curious) but...

 

There exists an SSDT somewhere in your system (OEM SSDT) that has the _PS3 method you're calling (why you're not calling _OFF, I'm not sure). So you can reach those methods (_ON or whatever) from DSDT just like you can reach them from the ssdt-1 you show above.

 

There is no way to change the behavior of _WAK/_PTS in DSDT without patching the DSDT itself.

 

Note that your _INI method defined in that SSDT likely overrides any _INI method already defined in one of the OEM SSDTs at the same path (\_SB.PCI0.PEG0). Maybe that's what you want, but you should be aware that the _INI code intended to execute (provided in OEM DSDT) will not execute. You can't have multiple methods of the same name at the same path... one will "win."

Can I copy the _WAK/_PTS methods to SSDT and just add the _OFF/_ON methods to it including what was originally there? Will it work.

 

Regarding the way I'm turning off the card. I was doing it earlier with just calling the _OFF methods but people recommended to so it through _PS3 as _PS3 method is in defined in most systems and will probably work without looking at the SSDT table for Optimus(OFF can be DOFF or OPOF). It was one recommended by the developers of Bumblebee project. The same way is defined in the first post of this topic.

You can creare a link to _OFF/_ON method in your dsdt by using External

External (\_SB_.PCI0.PEG0.PEGP._OFF, MethodObj)

than you can call _OFF in _PTS/_WAK/_INI in your dsdt. Make sure you included the ssdt containing _OFF method along with the patched dsdt/

No. Methods defined in DSDT always take precedence over methods with the same name found in an SSDT.

External (\_SB_.PCI0.PEG0.PEGP._OFF, MethodObj)
than you can call _OFF in _PTS/_WAK/_INI in your dsdt. Make sure you included the ssdt containing _OFF method along with the patched dsdt/

 

You missed part of the discussion. For some reason, webcivilian is averse to modifying the DSDT.

RehabMan - I already have a patched DSDT that works :)

 

I'm just trying this new method of not using a patched DSDT and using Clover to do patching on the fly. I guess I will patch in the _PTS and _WAK sections of the DSDT using Clover.

With Clover's support for "floating regions" (FixRegions_10000000) in a patched DSDT, there is little reason to expend so much effort to not patch DSDT.

      Hello a few days ago I installed a wireless card to get wifi called: Broadcom DW1820A model: 94350ZAE. Could someone help me to modify my efi folder to let the card work correctly? When I switch on the laptop everything is running ok in verbose mode but when later it appears the Apple logo to finally load everything all the computer get stucked so I can’t do anything (there is only the apple logo and a bar), the only way to use my laptop is disabling the wifi card from bios or using the boot arg: brcmfx_driver=1, and I don’t know why it happens this.
      I tried to follow/use some guides but I can’t fix it, so I need help from a professional of Hackintoshes…
      My laptop is a DELL vostro 5568 8 gb ram, i5 7200 2,4GHz, intel hd graphics 620 and the ssd 250gb.
      Here you can download my efi folder and a IOreg file of my computer
      If you need more information etc tell me.
      I only can upload 10mb and my efi folder is 25mb so I'll upload the most important files.
      Thankyou.

      Salve a tutti,
      ho provato diverse volte ad installare macOS sul mio laptop ma sempre senza successo, non riesco mai ad arrivare nemmeno all'installer!
      Ho tentato ormai diverse configurazioni/driver ma non capisco mai da cosa siano derivanti gli errori o i blocchi che mi trovo davanti e sto quindi cercando aiuto per capire come procedere 
      Nello specifico il config che sto provando ad utilizzare non mi trova per niente la partizione con l'installer, mentre un altro vecchio (presente sempre nella cartella di clover allegata con estensione .orig) si inchioda subito dopo la scelta della partizione di avvio.
      Qualcuno mi sa dare una mano su come superare ciò?
      Grazie in anticipo,
       
      Giacomo
       
       
      P.S. Le mie specifiche sono:
       
      - Modello ASUS N552VW-FI202T
      - Schermo 3840x2160
      - CPU Intel Core i7-6700HQ
      - RAM 16GB ddr4 2400mHz
      - Intel HD Graphics 530 + nVidia 960m 4GB (anche funzionasse solo la Intel sarebbe perfetto)
      - SSD 256GB
      - HDD 1TB

      The laptop in question: Acer TravelMate 8472 TM8472 (Model: ZQ3)

      The manufacturer specifications:
      Intel Core i5 520M 2.4GHz TurboBoost to 2.93GHz 3MB L3 Cache 14.0" 16:9 HD LED backlit LCD (specifically a AU Optronics AUO313C B140XW03 V1 - Thank you, HWiNFO64 !) with the embedded First Generation Intel HD Graphics IronLake, no nVidia graphics (Dissembling the machine clearly shows where it would be installed for the higher end option) The display resolution issue was resolved by following this guide: https://www.insanelymac.com/forum/topic/286092-guide-1st-generation-intel-hd-graphics-qeci/ The display - AU Optronics AUO313C B140XW03 V1 - was found to be a LVDS by searching for the Product Specification PDF as, again, Debian did not want to do " sudo intel_reg_dumper " and a lot of hopping from safe boot to regular boot through the GRUB2 and Chameleon bootloaders I found that Alternative 1 and 2 1X works but Alternative 1 gives me some really cool looking unintended gitched after effects "You're weird." I know. 4GB DDR3 Memory [it has been swapped out for the maximum that it can handle of 8GB] 320GB HDD (Western Digital, I wouldn't have it any other way...) The original has been swapped out with a same size to preserve the OEM recovery partitions unfortunately both of them are 5400RPM ("Why don't you go SSD?" I know the technology has become better but I still do not have a whole lot of trust in it - If you want to argue about it, sorry, Imma gonna ignore it. If it works, why change it) DVD-Super Multi DL Drive This fine dime will drive you nuts... there is a designated system managed eject button, much like on an actual Mac, that is next to the second wireless switching button. Do not press eject as the laptop is first booting up unless you want it to lockup before or during the BIOS boot screen "Acer Nplify™ 802.11 b/g/n" 6-cell Li-ion battery VERY NICE - NO MATTER WHAT OS I AM RUNNING, IT... FREAKING... LASTS  
      "Okay... what does it really have?" Well, all of the specifications listed above and then:
      "Atheros" Bluetooth; so says Hardware Vendor Detection from the Acer Support website - Broadcom; so says HWiNFO64 from PortableApps.com And then the sticker on the bottom says Foxconn BCM92046 ! ! ! (MAKE UP YOUR MIND!!! FOXCONN, ATHEROS, OR BROADCOM?!?!?! WHICH IS IT?!) Chicony 1.3M Camera (works no matter what if your into that stuff) LAN by Broadcom (BCM57760) WLAN by Broadcom (BCM943225HM) (No cellular modules are applicable to this model, there is a disabled mini PCI-E socket inside that is only good for a fourth expansion board USB port...) Alcor card reader (registers as a regular USB drive/stick to all operating systems unless you install the drivers in Windows, then it registers as whatever you shoved in there) EGISTEC fingerprint reader where a scroll button would be (works only in Windows after you install it) Synaptics TouchPad - TWO FINGER SCROLLING EVERYWHERE, yes can you tell that I actually do like this function? The Trackpad and Keyboard are handled by AppleACPIPS2Nub and ApplePS2Controller kexts I regretfully obtained mine from the other macx86 [I KNOW! I AM SORRY! I AM NOT HAPPY ABOUT IT EITHER!] I cannot help it if mine is just being really picky (at least I am admitting it, besides, they don't seem too friendly over there, they didn't seem to like the matter I installed 10.6 on a Pentium 4 3.4GHz and on an Atom netbook and the result was them just simply deleting my account [just for me to go back and remake it to dissemble their stuff to see what they stole... again...]) Intel 5 Series Audio but Conexant drivers work in Windows, weird. I use VoodooHDA 2.8.7 in Mac OS, anything older seemed to do NOTHING and a freaking telephone modem by Conexant but the Windows drivers are Liteon Did I mention that this thing is from 2010? "Why do you have such an old outdated-?" Because my work gave it to me for free  
      FakeSMC V6 and Plugins to use HWMonitor 6.16.1372 to its full potential  
      (I also have the HFS+ drivers installed so I can read [only] the files on the Mac partition)
       
      "How is it setup right now?"
      It is multibooted with:
      Microsoft Windows 7 Ultimate "That's on its way out very soon!" I have my ways of not being dumb online... I still use Windows XP online (*cough cough* Deepfreeze *cough*) Remix OS, a port of Android-x86 (very discontinued, looking into other versions) Niresh Mac OS X 10.8 with Chameleon "Why?" It's the last version of the big cats. Did you notice that they never did Lynx? Debian Linux KDE   "How did you do all of that?" And with a non-(U)EFI BIOS and no EFI partition, sorry, that is not what this thread is about... it was a metric ton of fun to get to work... LOTS of disk swapping and DBANs... and OSes like to manipulate partitions in each of their own ways and prevent other ones from installing without causing other conflicts like linux making a bunch of partitions because you told the Mac OS installer to format the drive with EFI in mind instead of MBR and so you have Windows, Linux but no Mac because the BIOS is only looking for FOUR partitions only and everything hits the fan including the kitchen sink...  
      "So what are you annoying us for?"
      Good question, because I am usually an introvert and usually just keep looking for answers but I could not find some. Jumping to it...
       
      What does not work and I would like thoughts on Bluetooth does not register, used to on previous installs (sorry, I did not pay attention to see if this was caused by me updating to 10.8.5 but that was necessary for the below functions) (It does not work in Debian either - Ignore) LAN and WLAN  - I have found Kexts (somewhere, I think I just lost them... dang it...) for the WLAN but I have yet to try them, nothing for the LAN I know this is cheating but I read that The NDISulator for FreeBSD (HINT HINT) is a port of NDISwrapper for Linux that runs Windows XP network drivers in Linux or BSD Brightness controls work from the middle down on the "Sun" brightness overlay, I got this far from following this: https://www.insanelymac.com/forum/topic/287133-guide-backlight-brightness-for-intel-80860046-1st-gen-hd-gma-5700mhd/ but I am kind of thinking of trying: https://www.insanelymac.com/forum/topic/287133-guide-backlight-brightness-for-intel-80860046-1st-gen-hd-gma-5700mhd/?do=findComment&comment=2214344 . My "magic number" is: 0xF        I used DSDTEditor in Windows, since I figured all the drivers are loaded, to extract the DSDT and compile something that somewhat works... Wake from sleep issue - I tried the above guide for that but I get no backlight and I can see that the cursor in the password field is not flashing when I use an external light source, but it will reboot when I press Ctrl + Alt + Power "button" (it is actually a slider) and then also clear my freaking CMOS right down to the clock... yeah I have the ACPI fix implmented and it usually works... DVD Player.app reports that no viable vidoe device was found (personally I don't care about the DVD Player.app problem, just wanted to put that out there for the heck of it)  
      Likely causes of: Bluetooth (BCM92046), WIFI (BCM943225HM) - So, I USED TO be able to turn on the WIFI from within Windows then reboot into Mac OS and have it work but I noticed recently that the indicator light for them extinguishes BEFORE it reboots now. When Windows or Android load, it lights up-- "No... really, captain obvious?!" --anyways working "No really Sherlock!" so OBVIOUSLY, the OS has to activate them... and preferably ignore the wireless switching button For the WIFI module, if you omit the 9 and HM in a search, results appear! Brightness - Will get reset to full "Bright light! Bright light!" when a "Load System Defaults" is applied from within the BIOS settings but like the WIFI and Bluetooth the OS will forcefully take control of it LAN (BCM57760) - I dunno...  when I search it, nothing comes up...  
      "Dude, what in the world is the point of this machine?" Cross platform software and driver development...
       
      Any help pertaining to the Bluetooth, WIFI, LAN, bizzar brightness and wake after sleep backlight issue would be wonderful... Thank you for your time and I hope that I helped anyone else out with some of their own issues pertaining to the Acer TravelMate 8472 TM8472 ZQ3 Medium-low model laptop...

      ACPI and Clover config for Acer Aspire v5-571PG
       
      Tested on Catalina 10.15.1 and Clover EFI 5098 (Should work on MacOS 10.9.x - 10.15.x)
       
      Not Working:
      - sd card reader
      - Atheros AR9462 (use a compatible USB wireless adapter, see below)
      - Touchscreen (MacOS 10.15 only)
       
       
      Notes:
      Disable Secure Boot and enable Legacy Boot. Legacy Mode is recommended.  
      **To reset your BIOS, power on the pc and hold the power button for about 30-40 seconds or you can short G2101 (RAM SLOT 1)**
       
       
      About the Atheros card:
      You can install ATH9KFixup (you will also need additional patches on 10.14+ to restore Atheros support) to enable this card, however,
      it will break sleep on MacOS 10.14+, it can freeze your OS at any time and it can freeze your network settings.
      Because of its instability it is highly recommended to buy a USB wireless adapter.
       
      You can find a list of working adapters, and the drivers, here.
       
       
      Additional things you will need:
      Latest Clover config (AcerAspireV5-571pg - CCE Bank) from here CloverEFI (download) or OpenCore (download - Untested) WhateverGreen (download) VoodooPS2 (download) VirtualSMC + SMCBatteryManager (download) AppleALC (download) Lilu (download) Mieze Realtek RTL8111 (download)  
      CloverEFI drivers you will need:
      ApfsDriverLoader EmuVariableUefi FSInject DataHubDxe VBoxHfs (if you have hfs partitions)  
      Remember to install BIOS drivers if you enable Legaby Boot.

      Acer Aspire V15 V5-591G - Catalina 10.15.1
      Original link:
      https://osxlatitude.com/forums/topic/11355-acer-aspire-v-15-v5-591g-catalina-windows-10/
      (Note: mine is 55TU version, but the bootpack will work fine with another versions of 591G, for example: V5-591G-71K2, -764Z, -59PU, etc.)
      Specifications:
      - Motherboard: USOPP_SLS (Skylake-H PCH)
      - BIOS: Insyde Corp. v 1.15
      - CPU: Intel Core i5-6300HQ 2.3 GHz (Skylake)

      - Battery: 6 cell 56Wh / 5040mAh
      - Connectors: 
      1x SD Card Reader 2x USB 3.0 (1x USB Charging), 1x USB 2.0 1x VGA 1x HDMI 1x 3.5mm microphone/audio combined jack connector 1x Ethernet (Rj-45) - Keyboard & Touchpad: Multi-Touch & Multi-gestures ELAN 501 Touchpad, Backlight Keyboard.
      Working:  
      - Wi-Fi (with BCM94352Z)
      - Bluetooth hand-off (With BCM94352Z)
      - Full Graphics enabled on HD 530: ig-platform-id: 0x191b0000 (HD 530 Mobile)
      - Display: if default colour profile is corrupted (blue is not actual blue but purplish) Use "Rec. ITU-R BT. 709-5" Color Profile (System Pref. -> Displays -> Color)
      - HDMI & VGA Outputs: AppleGraphicsDevicePolicy.kext Clover patch
      - Audio (ALC 255): (Internal Speakers, Internal Microphone, Headphone jack with AppleALC, ALCPlugFix -> layout-id=17)
      - Ethernet Realtek 8168/8111: RealtekRTL8111.kext
      - App Store, Messages, FaceTime, Siri, iCloud (native)
      - Integrated webcam (native)
      - 3.0 USB (native)
      - Touchpad and Keyboard (ELAN501): Fn keys are good, the weird thing is the Brightness key. On my keyboard it's Pause Break:Br-up, Fn+F12:Br-dwn-> To fix this try Karabiner (VoodoPS2Controller.kext), - for gestures try SmartTouchpad drivers
      - Battery info: Install ACPIBatteryManager.kext with Kext Utility or other installer.
      - Sleep Mode
      - SSD with TRIM enabled (to enable trim, open Terminal and write "sudo trimforce enable")
      Not working:
      - Original Wi-Fi (Qualcomm Atheros QCNFA344A):  unsupported, you need switch to BCM94352Z or just use a mini usb wifi dongle.
      - NVIDIA GeForce GTX 950M: Optimus not supported.
      - Card Reader: Unsupported -> Can't really fix because I don't have any SD Card at the moment, maybe can be fixed by adding Prod & Ven IDs to AppleStorageDevices.kext, I never used it anyway. name: "USB2.0-CRW" Prod ID: "0x0129" Ven ID: "0x0bda  (Realtek Semiconductor Corp.)"
      For Wi-Fi:
      - 1st method: You can choose an external USB wifi dongle (I used TP-Link Archer T1U (5GHz support), TP-Link has official macOS drivers, you just need to install it
      - 2nd and I think the best method: Replace your M.2 Qualcomm Card with a compatible BCM94352Z card (you will have hand-off Bluetooth too), just install the kexts (enabled with BrcmFirmwareRepo.kext, BrcmPatchRAM2.kext, FakePCIID.kext, FakePCIID_Broadcom_WiFi.kext, they're all in my attached zip). You could buy this card from ebay, aliexpress, or amazon
       
      Issues:
      - None
      BIOS Settings:
      - BIOS version 1.15 (irrelevant)
      - Secure Boot: Disabled
      - Touchpad: Advanced
      - Boot mode: UEFI
      Getting ready for Installation:
      - Download the Catalina install zip (bootpack & postinstall): acer_aspire_V591G-55TU_cata.zip
      Installation:
      - Create an installer with any method you know (- Mac: createinstallmedia - Windows: Transmac, Vmware, Win32diskimager)
      - Copy my Clover folder to the USB's EFI folder
      - Boot with the Installer USB
      - If you stuck in boot, reboot and in the Clover bootloader select "config_debug.cfg" -> you'll have more informations about the freeze
       
      Please open the README.rtf in my install zip for more informations about the USB Installer & Post installation!
      On Catalina the System folder is read-only, so you need to remount in rw to modify System/Library. 
      If you have a single RAM and getting panic at boot, then you need to edit the "config.plist" with these (SMBIOS->after "Version 1.0"):
      ->Edit "Frequency" and "Size" to match your RAM values
      <key>Version</key> <string>1.0</string> <key>Memory</key> <dict> <key>Channels</key> <integer>1</integer> <key>SlotCount</key> <integer>1</integer> <key>Modules</key> <array> <dict> <key>Slot</key> <integer>0</integer> <key>Size</key> <integer>8192</integer> <key>Frequency</key> <integer>2133</integer> <key>Type</key> <string>DDR4</string> </dict> </array> </dict> </dict>  
      PowerManagement  fix:
      Set HWPEnable=YES in Clover (already set), CPUFloor to "700", Frequency to "2300" and "3200"(Normal and Turbo, if you have i7-6700HQ version then it should be "2600", "3500") and "FrequencyVectors" from "0x0d000000" to "0x07000000" in "S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Mac-A5C67F76ED83108C.plist", MSR _xcpm_idle Patch to KernelToPatch in Clover (If you have High Sierra, change "MatchOS" to 10.13):

      <key>KernelToPatch</key> <array> <dict> <key>Comment</key> <string>MSR 0xE2 _xcpm_idle instant reboot(c) Pike R. Alpha</string> <key>Disabled</key> <false/> <key>Find</key> <data> ILniAAAADzA= </data> <key>MatchOS</key> <string>10.14</string> <key>Replace</key> <data> ILniAAAAkJA= </data> </dict> </array> Reboot, and it's 800MHz in idle state, same on Windows.
       

      Elan SmartTouchpad
      I only use scrolling, one-, double- & tripletap
      If you want to try other gestures go to this link for more informations, options (v4.6.5) ->  DETAILS ABOUT THE SMART TOUCHPAD DRIVER FEATURES
      Fn Brightness keys not working with this, tried several things without success. With VoodoPS2Controller it's working, but you'll have no gestures (neither scrolling).
       
       
      Before updating to a new version of Catalina please update kexts (and clover if necessary) to newer versions to avoid kernel panics.
      Generate a serial number with Clover Configurator.app (open up your config.plist with CC then -> SMBIOS -> Serial Number -> Generate New)
       
      Catalina & Windows 10 Dual-Boot:
      Dual-boot clean install (on one drive), UEFI Only:
       
       Boot into your Mac installer, Create 2 partitions in GUID table (1 for Win (I used FAT32 but I think it doesn't matter what you choose), 1 for Mac),   Install Mac, boot with your USB, mount your EFI partition (use terminal or an EFI mounter app), create an EFI folder (if there is no folder), copy the CLOVER folder I attached to the EFI folder, restart,  Boot into your Win installer, Format the partition you created for Win, install.   Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       5.  You're done! It will booting into Clover when you start the system, and you can select Win or Mac (or another OS if installed on a 3rd partition).
       
      Dual-boot with Windows installed first (on one drive), UEFI Only:
      If you already have Windows and you don't want to lose all your data there is a hope:
      I created a video from this restore method: [Hackintosh] Dual-Boot High Sierra & Windows - when Windows already installed - no data waste - UEFI
      You need bootable Mac Installer and a full system restore image (link is in my video's description).
      (You may see errors if your EFI partition is not 200 MB)
       Boot into your Windows, resize your partition or create one for Mac.  Boot into your Mac installer and in Disk Utility format the partition you created.  Restore from image: select your full system restore image.  When it's finished restoring you just need to restart, then boot to the system with your usb.  When you successfully booted to Mac desktop, mount your EFI partition (use terminal or an EFI mounter app), open EFI, you will see there is a Microsoft folder already (don't touch that!). Copy my CLOVER folder to the EFI folder then Restart.  Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       7.  You're done! You can select your old Windows and your new macOS!
      (Only tried with Windows 8/8.1/10. I don't know Windows 7,etc.)
       
      IF YOU GETTING ERRORS DURING MAC RESTORE:
      - Make sure you have partitions in GPT
      - Windows using 100 MB EFI and will annoy the Mac restore. Don't worry, just ignore the errors.
       
      IF YOU GETTING ERRORS DURING WINDOWS INSTALLATION (could not be formatted, etc):
      - Make sure you have GPT partitions, and GPT (UEFI) installer, also disconnect all external storage drives (except the installer USB)
       
      IF YOU USED RESTORE METHOD THEN CAN'T MOUNT YOUR EFI PARTITION (No EFI partition found):
      - It's because your EFI is not 200 MB or not an "Apple" original EFI,  but do not worry, try another EFI mounter, or mount from terminal (I used EFI mounter v3: Getting errors, but you can mount and use without problem)
      - You also could "mount" the EFI from Windows:
      1st method: open cmd in administrator mode and type:
      diskpart list vol (Now select the "System" volume,(FAT 32) For example I select 4) sel vol 4 list part (Select System type partition, for example 2) sel part 2 assign letter=b (This will "mount" your EFI partition) Open Explorer++ or TotalCommander in administrator mode to manage EFI remove letter=b (This will "unmount" your EFI) 2nd method: open cmd in administrator mode and type:
      mountvol b: /s (This will mount your EFI) Open Explorer++ or TotalCommander in administrator mode to manage EFI mountvol b: /d (This will unmount your EFI) Thanks to all OSXLatitude members for helping me out! (Jake Lo, Hervé, Bronxteck, black.dragon74)!
