VII. Important thing

> All kext below should be updated from my git for this laptop:
    + AppleALC.kext ( Verb changed to support ALC295 in 7591, layout 13 modified to work with combojack )
        > Find it here: https://github.com/tctien342/AppleALC
        > Find Combojack here: https://github.com/tctien342/ComboJack
    + CustomPeripheral.kext ( Fake apple device, change it if you have different devices )
    + VoodooPS2Controller.kext ( Fixed panic when work with voodooi2c )
    + CPUFriendDataProvider.kext is for my 9300H, maybe it different for you, using https://github.com/stevezhengshiqi/one-key-cpufriend to regenerate it if your cpu is different. 

> After update or install MacOS: Please run rebuilt your kext ( Using Kext Utility or something can handle it ) for stablity and your stoping trackpad.

VIII. Step to install

1. Prepair an Mac installer in USB with Clover added ( Use unibeast to create it )
2. Replace EFI folder in USB EFI partition with this shipped EFI folder
3. Boot into USB and select MacOs installer
4. First boot Trackpad will not work, need and mouse connect through USB, Follow mac install instruction you can find it on tonymacx86 or other hackintosh forum
5. After install success, boot into MacOS, run ComboJack Alc295/ComboJack_Installer/install.sh in terminal
6. Use Kext Utility to rebuild kext then reboot
7. This time trackpad and audio will working normally, then you need to use Clover EFI bootloader to install clover to EFI partition
8. After install success, using Clover Configurator to mount your USB EFI partition then copy it to your System EFI.
9. After System EFI replaced by your EFI, Using Clover Configurator to change SMBIOS, generate your serial and MBL
10. Optional to fix iMessenger if you dont have compatible wifi card
    + Go to https://www.browserling.com/tools/random-mac an click GenerateIP and pick an Mac address
    + Put it into SSDT-RMNE.dsl in fake ethernet like below and save as aml file then copy to ACPI/Patched in clover
    + Copy NullEthernet.kext into your clover->kexts->other

IX. WIFI Replacement

Using new card ( DW1820A tested)

Using DW1820a

+ Mine is CN-0VW3T3 0x106B:0x0021, not tested in other verizon yet
+ You need masked your pin like this: https://osxlatitude.com/forums/topic/11540-dw1820a-the-general-troubleshooting-thread/?do=findComment&comment=91179
+ Add flag below into boot flag
+ Add Devices below into Clover -> Devices -> Properties
    + PciRoot(0x0)/Pci(0x1d,0x6)/Pci(0x0,0x0)
        > AAPL,slot-name: WLAN
        > compatible: pci14e4,4353
        > device_type: Airport Extreme
        > model: DW1820A (BCM4350) 802.11ac Wireless
        > name: Airport

+ Add kext to clover:
    + AirportBrcmFixup.kext
    + BrcmBluetoothInjector.kext
    + BrcmFirmwareData.kext
    + BrcmPatchRAM3.kext
    + BT4LEContinuityFixup.kext (Handoff fix? maybe)
    brcmfx-driver=1 brcmfx-country=#a #(wifi fix)
    bpr_probedelay=100 bpr_initialdelay=300 bpr_postresetdelay=300 #(blue fix after sleep)

<> Other support card like DW1560 and DW1830 you can google and test it, much easy than DW1820A

Using usb wifi
