Rev 4004

Code introduced in Rev 3710 to modify the boot character only works for

Start64H1.com, Start64H2.com, Start64H2.com, Start64H4.com

and corrupts the boot code for

Start64H5.com, Start64H6.com, start32H.com2

Modified ebuild.sh to exclude modifying the corrupted boot code

Rev 4020

A possibility to patch boot.efi on the fly and a possibility to disable some of these patches from Clover GUI.


What is "boot.efi"? 

Clover is Boot Manager providing us a chooser between different OS bootloaders:

bootmgfw.efi for Windows

grubx64.efi for Linux

boot.efi for MacOS.

Each substance of MacOS has own boot.efi located on the same volume in /System/Library/CoreServices/

This is EFI application working in EFI environment provided by UEFI BIOS or by CloverEFI.


What boot.efi does?

- create DeviceTree and fill it with initial information from EFI (SMBIOS, ACPI, DeviceProperties etc)

- load kernel, kexts, caches...

- make memory map

- performs start OS, or hibernate wake, or NET load, or something else

- ask user for password at FileVault2

- other preOS procedures


Is it opensource? No.

But we have some similar sources to see how it works

     macosxbootloader (Hackintosh version).    

and by Pike'R Alpha at github. I don't know the origin of the sources.

//	created:	4:11:2009   10:40
//	filename: 	Console.cpp
//	author:		tiamo

Looking at the sources we can find what to patch for our purpose.

Rev 4028, 4030, 4031

  • Renamed build_gcc5.sh to build_gcc6.sh and modified to build GCC 6.3 toolchain with LTO support.
  • To build with GCC 6.3, still use -gcc53 toolchain parameter to ebuild.sh.
  • Corrected mistake in r3730 that made -gcc53 toolchain use native GCC instead of cross-compiler.  Update: In Rev 4030, location of GCC for -gcc53 toolchain is determined based on whether building on Linux or Darwin.
  • Added script buildmtoc.sh to build mtoc from cctools-895.  Default install location is $TOOLCHAIN_DIR/bin/mtoc.NEW.
  • Update: In Rev 4031, adapted CloverPackage/makeiso script to work on Linux.

Rev 4034

  • build_gcc6.sh built both native Darwin GCC and cross-compile GCC for linux-gnu.
  • Clover does not use the native Darwin GCC.
  • native Darwin GCC was only used to build the cross-compile binutils and GCC.
  • Xcode can build the cross-compile binutils and GCC.
  • Eliminated the building of native Darwin GCC from build_gcc6.sh.
  • The cross-compile binutils and GCC are now built using Xcode.
  • Eliminated dependence in Clover on mere existence of $TOOLCHAIN_DIR/bin (the cross-compile tools are in $TOOLCHAIN_DIR/cross).  However, if you build nasm with buildnasm.sh - it is still placed in $TOOLCHAIN_DIR/bin and run from there.

Rev 4050 - 4052

  • Created XCODE8 toolchain with following differences from XCODE5
  • Uses clang native -target x86_64-apple-darwin instead of hybrid -target x86_64-windows-macho.
  • #defines EFIAPI to __attribute__((ms_abi)) similar to GCC builds.
  • Uses __builtin_ms_va_list for VA_LIST.
  • Changed BUILDRULEORDER from "S s nasm" to "nasm S s" so nasm is used on assembly sources.

This toolchain exposed some type mismatches for functions with EFIAPI.  Also exposed some use of incorrect va_list in variadic functions that are not EFIAPI (present in OpensslLib and GrubFS).  These issues are present in GCC build as well, and should have been discovered.  They weren't, and GCC generates incorrect code in some of the cases.  Anyhow, I fixed all these instances.
[Edit: apologies to GCC, it's set to -mabi=ms in tools_def.txt, so uses ms_abi on all functions.  GCC does discover the type mismatches without this setting.]


A brief history of va_list issue with -target x86_64-windows-macho, just for the record

  • Before LLVM clang 3.7, Apple clang 7.3, this target only had __builtin_va_list.  This implementation worked (other than some bugs in old versions of Xcode), but it creates a va_list that is incompatible with the one created by Microsoft in Win64 ABI.
  • [Microsoft implements va_list using a char* which points to the parameters spilt on the stack and is passed by value.  The clang implementation places the Microsoft va_list in a struct that has same build as sysv_va_list (24 bytes, 16-byte aligned), and passes the sysv_va_list by reference (address of the Microsoft va_list).]
  • LLVM clang 3.7 to 3.8.x, Apple clang 7.3 to 8.0 had a __builtin_ms_va_list for this target.  The va_list was a char* the same as Microsoft, passed by value.  It generally worked, but there was a bug that __builtin_va_arg would not always advance the pointer by the correct # of bytes (LLVM bug 27663).  This bug has not been fixed, but instead, the target no longer supports __builtin_ms_va_list and gives a compile-time error message when this type is passed to __builtin_va_arg.  It can't be used anymore.

In -target x86_64-apple-darwin, there is an implementation of __builtin_ms_va_list, which works similar to the Microsoft one (and same as GCC.). In this target it is necessary to use __attribute__((ms_abi)) to get Win64 ABI for a function.  There are other side-effects of using this target.  For example, any Win64ABI function that calls a SYSV_ABI function spills the SSE registers XMM6-XMM15.  This is because they're considered non-volatile in Win64ABI, but volatile in SYSV_ABI.  As a result of this overhead, the code generated by XCODE8 is generally bigger than the code generated by XCODE5.
I've also compared XCODE8 with -flto and -fno-lto, and there's almost no difference in the size of CLOVERX64.efi.


Edit: For the record, Apple's boot.efi is compiled with clang+mtoc, -target x86_64-windows-macho and uses __builtin_va_list for VA_LIST.

Rev 4049

Compatibility with 10.12.4 installer.

It has new boot.efi location and will not work with previous Clover revisions.


Rev 4053

Use UTC time for nvram.plist.

The problem is a file on HFS+ partition has UTC modification date while same file on FAT32 (EFI partition) has local time.

Clover will compare several nvram_plists found on different partitions to decide who is newer. In this case time zone difference leads to bug.

This commit modifies save_nvram script to make same time stamp.

Rev 4110

Fixed External Clock calculation and QPI.
No more need to follow this process. Clover automatically resolves it now.
Note: Real Mac’s report a hw.busfrequency = 100000000

To achieve that with Clover here’s what to do:
1 - Drop SMBIOS table type 132 for Sandy Bridge and newer CPU’s. Clover does this if you set QPI to a string value of 0.
2 - Set SMBIOS table type 4->ExternalClock to 0 (or 25Mhz as a real Mac). This currently has to be done in the source code and re-compile Clover.

Rev 4111

Improved CPU log
 - Finally: ExternalClock=25MHz BusSpeed=100000kHz CPU=2300MHz PIS: hw.busfrequency=100000000Hz

added NvidiaNoEFI thanks to FredWst. link

 - If I choose Nvidia injection with bad EFI bios screen is coming scrambled.

Rev 4130

improved DualLink if can't read correct resolution

 - Support DualLink in GUI


 - Clover can read correct resolution on most of system. but can't read correct resolution on some system. example, lenovo laptop. Link

 - Default DualLink auto-detection. if has problem to read resolution, try

   Low resolution(1366x768-) - DualLink = 0

   High resolution(1400x1050+) - DualLink = 1

		<integer>you want</integer> 

Rev 4132

Fixed DualLink in GUI

 - DualLink is only applicable to intel graphics and amd radeon graphics except nvidia graphics(confirmed from RealMac).


Rev 4135

Added option to easily use debug in GUI

 - Easily use debug of KernelAndKextPatches in GUI. no need to set "Debug = true" on KernelAndKextPatches in config.plist. 

 - Of course, it supports "Debug = true" on KernelAndKextPatches in config.plist if want to always see debug log

Rev 4154

Boolean "KernelIvyXCPM" under "KernelAndKextPatches" to enable XCPM on Ivy Bridge CPUs. It looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

Note: If you had to enable AsusAICPUPM/AppleIntelCPUPM in the past to bypass AICPUPM kernel panic, then you might also need to turn on KernelPm with the new KernelIvyXCPM. Thanks to @ACIDSkyRU for pointing this out.

Rev 4161
check for BiosVersion and BiosReleaseDate by Sherlocks
- if user has old BiosVersion and BiosReleaseDate at config, no more need to always update manually.
- The clover judges the user's BiosVersion and BiosReleaseDate and keeps them up-to-date.
- Of course, it is based on the latest clover platformdata. The newer BiosVersion can be used at config by user when update macOS.
- User can avoid problems such as Thunderbolt update messages on some smbios or high Sierra installation problems.

Standard BiosReleaseDate : MM/DD/YY or MM/DD/YYYY
-The standard format differs depending on the model. Clover automatically adapts this part to the model. Either of these can be used at config.


Rev 4162

Rev 4170

Added ability within the Clover GUI to set/unset Nvidia value for
NvidiaSingle and NvidiaNoEFI

The NvidiaNoEFI change was made by suggestion and patch by FredWst
reference topic here -> http://www.insanelymac.com/forum/topic/306156-clover-bugissue-report-and-patch/?p=2443062

The parameters are readed (if exist) from config.plist

This is a handy way to test those value without edit the config.plist to find the
expected result.

Rev 4195

Set backlight control for Nvidia mobile cards.

Снимок экрана 2017-09-06 в 23.47.50.png


In my case there are:

DSDT_FIX: AddPNLF_1000000

OEM SSDT NvdTable, but _DSM -> ZDSM corrected by Clover. No new _DSM

No additional kexts.


A trick to assign keys to reduce/increase brightness:

insert temporarily USB keyboard

Control Panel -> Keyboeard -> Shotcuts -> Screen (appeared due to USB keyboard)

assign F1 to Reduce brightness and F2 to Increase. No other combinations!

After removing the USB keyboard assigning will continue working.

Rev 4200

Compatibility with Windows 7.

Old fix FixDarwin_0002 made ACPI behaviour like Windows XP (Windows 2001 SP #). Usually it gives OSYS=0x7D2.

It is too old for modern computers. For example USB3.0 may not work.

So I made new fix "FixDarwin7_10000" which makes compatibility with Windows 7 SP1 (Windows 2009). It should gives OSYS=0x7D9.


Discussion: I will not make Windows 2012 or 2016 because MacOSX is more ACPI system and more oriented on DSDT then W2012 which has own drivers no matter what ACPI said.

Rev 4202

Kext Injection Management.

Allow user to disable specific kext(s) in Clover/Options/Kext Injection Management. This provide user flexible to debug kexts especially in new system.


Rev 4204

User can block plugin kext in Kext Injection Management as well.


Discussion: some users also require disable kext injection in config.plist as well. 


Rev 4208

Fix APFS installation issue on ESP/EFI partition by Rehabman.


Rev 4209

Remove options that are unrelated to Clover in menu by Slice.  Because we now have more general way to disable specific kext injection.

      Budget Workstation MacOS 10.14.1 build: z370 AORUS Gaming 5 - i5-8600K - RX 580 - UHD 630
      flawless iGPU/dGPU integration, fast FCPX editing/rendering, great overall performance for ~$1200 / ~£1000
      Update: updated WhateverGreen and Lilu, then updated OS to 10.14.3 and everything is fine! Even iMessage, which previously I hadn't been able to make work, is now working - possibly the update flushed the NVRAM?
      I'm gonna come straight out and admit it - I used newb tools which are considered taboo on InsanelyMac, and so this isn't so much an installation guide as it is a green flag to anyone considering the same hardware. My first and previous Hackintosh project was just over ten years ago and this site was massively helpful, so this is my (very small) way of giving back.
      CPU: Intel i5-8600K 3.6GHz hexacore (contains UHD 630 iGPU)
      CPU Cooler: be quiet! Pure Rock Slim (no paste needed, and fan facing front)
      Mobo: GIGABYTE z370 AORUS Gaming 5 (WIFI)
      RAM: 1x 8GB CORSAIR Vengeance LPX C16 2666MHz (in first slot)
      GFX Card: Sapphire RX 580 NITRO+ SE
      SATA: used ports 0, 1, 3, 5 (HDD problems when connected to port 4)
      HDD: generic
      DVD Drive: generic
      PSU: EVGA 500W Semi Modular (but you should get 650W!)
      Case: CoolerMaster CM590 III
      Fans: 2x stock case fans (one sucky on front, one blowy on back), 3x be quiet! BL046 120mm fans (two blowy on top, one sucky on front). Airflow near-perfectly balanced.
      With the Clover configuration, you want to pay close attention to all things relating to graphics. There are some specific settings for ACPI, Boot, Devices and Graphics which should be copied exactly in order to get the iGPU and dGPU to work in perfect harmony. For instance, make sure you use ig-platform-id 59120003 rather than 59120000 if you want FCPX to be usable. With the right settings, FCPX will not only run, but run flawlessly.
      I was not able to figure out how to make NVRAM/PRAM behave itself, and I got errors when I tried to issue relevant commands. As a result, I could not at first get iMessage to work properly. It worked once on my first installation attempt but not from subsequent attempts. This Clover configuration therefore has no consideration whatsoever toward iMessage reliability - however, iMessage ended up working somehow, anyway - I noticed it after I'd updated to 10.14.3 but this may just have been coincidence.
      Onboard WiFi does not work. There is no driver for it. I'm using wired ethernet to a bridge router as it was cheaper than getting a compatible PCI card.
      Audio is working well after I installed the z370 audio patch, then the ALC1220 codecs, then AppleALC.
      With kexts for generic 3rd party SATA and generic 3rd party eSATA, my HDDs and DVD drive work perfectly well.
      Sleep/Wake functions run perfectly. iCloud functions run perfectly. Shutdown leaves the mobo LEDs on, annoyingly.
      My USB 3 ports seem to suffer from low power output, and I don't know why.
      Overall, this system appears to run about as well under MacOS 10.14 Mojave as it does under Windows 7. I would solidly recommend this build to anyone looking to build a computer for workstation purposes, on a budget.

      Good morning, everyone, I'm sorry if I was wrong in choosing the topic but I need help.
      I have found it extremely difficult to mount a Hackintosh in my acer.
      I5 2430m 2.4 6GB RAM
      Mobo P5we0 - Intel intel Graphics 3000
      At the moment I have not found out what my audio codecs are.
      but I'll leave the link on the motherboard.
      however, my real problem is several.
      I have already used the itakos image, I have already used several images that could be installed normally and that after installing the image I do not have internet via cable or wireless.
      And another, I already looked in other forums and I know that I will be called a donkey in the logical question but I have not been able to install the [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url] or clover to start from the Hard Disk, so I do not know what to do.At the moment I still do not know if there has already been someone who has already installed the High Sierra or just the Sierra in this notebook model and obtained permanent success.
      If anyone can help me, I'll be grateful.
      Installations without success, but with the system already installed in ACER;
      All with the same symptom. Starting only by the bootable USB stick and without internet connection via cable and wireless.

      Since rev 4844 Vector Themes are supported and there are ready-to-use Clovy by Clovy, cesium by Slice and BGM_SVG by Blackosx.
      You may see it's structure to create own theme
      Now I want to add vector graphics support in Clover. See rev 4560 and later.
      It is not working yet but designers may begin to create Vector Themes.
      It supposed to consist of SVG elements and has design size. It will be rendered to any screen size scaled from design size.
      What application in macOS can create SVG graphics?
      Inkscape is not working in macOS 10.11+. Pity.
      LibreOffice Draw works with SVG but buggy.
      Boxy SVG cost 10$ but looks good enough. It creates the best in simplicity files and have more then enough features.
      Illustrator is good but expensive.
      How to improve SVG file?
      Clover has restricted support for SVG. It is your job to make compatible file and as small as possible to speedup rendering.
      Some helps:
      Help:Inkscape – From invalid to valid SVG Inkscape files
      From invalid to valid SVG Adobe Illustrator files
      From invalid to valid SVG files of other editors: BKchem, ChemDraw and CorelDRAW
      Help:Illustrator – Assistance with creating and saving SVG images in Adobe Illustrator that will pass W3C validation
      User:Quibik/Cleaning up SVG files manually
      Later I will write own instructions specific to Clover abilities.
      How to create SVG fonts?
      You can google to find ready-to-use SVG fonts.  I found some problems with too beaty fonts: slow rendering and overflow crash. Be careful.
      You can get ttf or otf fonts and convert them into svg by using online WEB services. Not a problem to google.
      But then I want to find a way to simplify the font to reduce a size and speedup rendering.
      You can create own font by FontForge It is opensource and available for Windows, Mac and GNU+Linux. It creates otf font which you can convert to svg font.

      App alternative:
      ESP Mounter Pro: per montare la partizione EFI
      Vi illustrerò tre metodi per creare la usb, ma sono ben distinti… quindi usatene soltanto uno
      Metodo 1: “Install Mac_OS_X.command” Metodo 2: “Create Install Media di Apple” Metodo 3:  Metodo Manuale Alla fine delle preparazione dell’installer, tutti i metodi necessitano l’installazione del Bootloader Clover sulla a vostra USB.
      PUNTO 1: che la vostra usb sia stata preventivamente nominata USB (caratteri maiuscoli) Tabella di partizione GUID e la formattazione in  Mac esteso Journaled.
      PUNTO 2: che l’installer di OSX si trovi in Applicazioni
      Utility Disco 
      Selezionate la pendrive, andate su “partizione”, selezionate “1 partizione”, impostate Mac OS esteso journaled e date il nome USB, poi in basso cliccate su opzioni e scegliete Tabella partizione (GUID), poi “applica”.
      Riporto nuovamente l’operazione sopra citata adoperando dal nuovo Utility Disco introdotto su El Capitan.
      Rimane ovviamente invariato nome della usb in ==>> USB (maiuscolo), la formattazione in Mac esteso Journaled e sia la mappa partizione in GUID
      Da utility disco selezionate la usb, cliccate su inizializza.
      dal menù a tendina scegliete la relative impostazioni
      Procedura effettua da High Sierra è la stessa della precedente, l'unica attenzione e operazione da aggiungere in primis  è cliccare nel menù a tendina in alto sulla sinistra di utility disco e selezionare "mostra tutti i dispositivi"
        METODO 1: "Install_Mac_OS_X.Command" Lo script che trovate allegato in fondo alla guida permette la creazione dell’installer in maniera automatica
      Include la possibilità di scelta di tre versioni di osx
      Yosemite El Capitan Sierra Il risultato finale è come quello del metodo "manuale" descritto nella guida, per cui l'installazione avverrà in un solo passaggio, non in due come con il metodo createinstallmedia. 
      Offre inoltre la possibilità di inserire un kernel patchato, utile, per esempio, per chi usa AMD.
      Rimane invariato il nome dato alla usb in USB, mappa partizione e tipo di formattazione
      Se la vostra usb non sarà rinominata nel modo corretto, verrete avvisati dal terminale, quindi non dovrete far altro che apportare la relativa modifica e rilanciare nuovamente lo script
      Metodo 2 
      L'intento è quello di usare la procedura fornitaci direttamente da Apple, "createinstallmedia", introdotta  con Mavericks. 
      Tale metodo prevede l’uso del terminale che via via se ne sta perdendo il “valore e l’uso”
      Inizialmente per i neofiti potrà sembrare problematico ma alla fine non è così.
      Durante il post installazione alcune operazioni ne richiedono l’ uso.
      Perciò mi sono chiesto perchè, qualora uno volesse, non far conoscere da subito un po’ questo “strumento”???
      Per favorirvi vi ho allegato i comandi già  “pronti”, i quali li potrete copiare ed incollare sul terminale.
      A questo punto aprite il terminale, copiate ed incollate il comando sottostante e premete invio, digitate la vostra password e premete nuovamente invio.
      Comando per creare USB con Yosemite:
      sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction  
      Comando per creare USB con El Capitan
      sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction Comando per creare USB con Sierra 
      sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ Sierra.app/ --nointeraction Per creare USB con Hight Sierra o Mojave usate --> C_I_M (aggiornato per 10.14)
      Funziona con il drag & drop sul terminale, in questo caso non vi è necessità che la usb sia nominata in un determinato modo ed essendo basato su create install media ovviamente funziona da 10.9 a 10.14.... 
      Potete adesso passare ad installare il bootloader Clover sulla vostra usb.
      Avendo usato questo metodo l'installazione si dividerà in due fasi, perciò dopo il primo riavvio e necessario far partire nuovamente l'installer, selezionare lo stesso disco senza formattarlo.
      Finita questa ulteriore fase , l'installazione sarà terminata
      METODO "MANUALE"....  (lascio per futura memoria-Compatibile fino a 10.12)
      **Nota:** Installazione in UEFI  dipenderà dalla scheda madre in vostro possesso, quindi se non supporta tale opzione , il bootloader dovrà essere installato in  modalità Legacy.
       Vi invito, qualora non sapeste questa informazione, a recarvi nel sito ufficiale del produttore e controllare le informazioni a riguardo
      Fatto questo dobbiamo installare  Clover sulla usb.
      A seconda del tipo di Bios o al tipo di installazione che vogliamo fare UEFI o Legacy avremo ovviamente configurazioni diverse in questa fase.
      Lanciate il pkg.

      Cambiate la destinazione di installazione ad USB oppure Install Mac_OS_X (a secondo del tipo di creazione eseguita)
      Successivamente clicchiamo su "Ad Hoc"
      Per Installazione UEFI
      Mettete i flag   : Installazione solo per avvio UEFI
                               : installare Clover nella ESP
                               : Driver64UEFI  AptioMemory --> (consigliato) 
                               : Driver64UEFI  ApfsDriverLoader --> (consigliato) --> sostituisce l'uso del driver apfs.efi
                               : Selezionate l'altri driver come da successiva immagine,
      *Nota: Altri driver che si possono usare  al suo posto  sono:
      Proseguite con l’installazione.
      ** Ricordate che avrete accesso a questa cartella dopo aver montato la partizione EFI**
      Per installazione Legacy
      Impostazione per config.plist:
      Con clover configurator “montate” la partizione EFI della usb.
      1) Per fare questo nel menù di sinistra, cliccate su “Mount EFI”
      2) individuate la partizione relativa alla vostra usb, a questo punto montiamo la relativa partizione EFI  selezionando l’apposito pulsante “Mount Partition”
      3) Successivamente cliccate su “Open Partition”.. recatevi in EFI/Clover ed aprite il config.plist
      4) Sezione ACPI: Disabilitate tutti i fix sia del menù 1 che del menù 2
      5) Sezione BOOT: Sole se si sta installando Yosemite mettete il flag su kext-dev-mode=1
      6) Sezione RT Variables: Se si sta installando El Capitan oppure Sierra, aggiungere i valori: BooterConfig= 0x28, CsrActiveConfig= 0x67
      7) Sezione System Parameters: Su inject kext mettete YES
      Nota: Su El Capitan, è stato introdotto SIP (System Integrity Protection)
      Recatevi in EFI/Clover/kext/10.x 
      X= alla versione di osx che state installando. Per esempio se installerete Yosemite dovrete recarvi nella cartella 10.10, con El Capitan in 10.11….ecc
      Se non ci fosse tale cartella, createla e nominatela voi a “modo”.
      Copiatevi all’interno FakeSmc.kext
      *Nota se venite già da altre vostre configurazioni, oltre kext sopra citato ,potete mettere gli altri necessari per il vostro hardware
      Stessa cosa se avete DSDT e/o SSDT potete copiarli in EFI/Clover/Acpi/Patched
      Per High Sierra:
      Scaricare il driver apfs.efi a fine guida, collocarlo:
          --> EFI/clover/Driver64UEFI se stiamo usando UEFI
      --> EFI/Clover/Driver64 se stiamo usando Legacy
      Per chi volesse continuare ad usare HFS vi rimando a questo post:
        Come installare High Sierra in HFS direttamente dalla usb  
      Utenti Laptop:  Nel 99% è obbligatorio disattivare la grafica discreta Nvidia/Amd per installare questo nuovo osx
                                     Quindi aggiungete --> SSDT-Disable_DGPU.aml.zip
                                     in EFI/Clover/acpi/Patched della usb
      Per Mojave:
      Scaricare il driver apfs.efi per 10.14 a fine guida, collocarlo:
          --> EFI/clover/Driver64UEFI se stiamo usando UEFI
      --> EFI/Clover/Driver64 se stiamo usando Legacy
      Versione di clover non antecedente a V_4015
      Volete usare HFS?
      E' possibile fare un installazione diretta su altro disco o partizione, nel caso può essere usato anche per effettuare aggiornamenti...
      nel caso guardate...
       Mojave in HFS 
       Oppure direttamente da usb  
      Fatto questo avrete la vostra USB bootable per installare OSX.
      ………Non scordatevi Fakesmc.kext da mettere nella relativa cartella…. senza il quale non farete mai il Boot......
      *NOTA: se usato il terminale per la creazione della usb, l'installazione si dividerà in due fasi, perciò dopo il primo riavvio e necessario far partire nuovamente l'installer, selezionare lo stesso disco senza formattarlo.
      Finita questa ulteriore fase , l'installazione sarà terminata
      **NOTA** Se avete processori Broadwell,Skylake o Kabylake...usate FakeSmc.kext e relativi sensors che trovate all'interno del secondo pacchetto.. (potete usarlo anche sui precedenti senza problemi, essendo una versione più aggiornata ha ulteriore supporto per le cpu più recenti)
      Update: Fakesmc e sensors versione 6.26
      Post installazione... post #2           
       Buon Hack….. 
      Aggiornamento:Install_Mac_OS_X.command.zip (compatibile da 10.10 a 10.12)
