Lenovo ThinkPad T420 with UEFI Only

I'm doing so many test with different types of setup and configurations that I've didn't noticed that... I mean sleep doesn't work as expected sometimes but I was always blaming something else than the DSDT. I guess I should look closer into it.

What UEFI Bios version you are at now? And can you write down the steps to reproduce the sleep problem.

Also I have hibernatemode disabled:

sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage

 

I use the original 1.43 bios now.

 

How does your system run now then? I am running OSX only now, and I use it for school every day (Yeah it's a bit tricky but it does work much better then Windows).

 

 

EDIT: disable hibernate works really well, it goes to sleep faster (immediately) and it wakes up with the same speed as well!

 

Can you tell me how your testing with the other sound kext is going? I can't get it to work yet, I've read trough the tread but I'm not much wiser yet haha.

 

I can confirm that everything that worked before update keeps working after update to 10.8.2 btw. It runs really stable and fast, much better then with chameleon and non-efi use.

 

Joke is, that with the use of EFI, you really get all the "toys" you have with a real mac. Like you mentioned in your first post. Even Bootcamp seems to be working.

In general I'm very happy about the result, but there are few little things that are still bugging me.

- brightness is lower than default (i use bottom-right corner to put display to sleep and wake it up for better brightness)

- SD card reader not working (though I use the pci-express to SD-card adapter)

- it would be nice to have a better mouse driver

Yeah indeed. Brightness is not really an issue in my case, because I use mine for school. Which means, I use lower brightness anyway for longer battery life, but I put it to sleep every now and then as well.

I was searching the net for a possibility to use multitouch like the newer MacBooks have (three finger window switching etc), would be great it there just was sectretly hidden button to turn multitouch options in prefpane for touchpad...

 

can you tell what you have done to make sound kexts from the project you mentioned? I didn't get the way he got it to work.

I always install new kexts by /Extra/Extensions/ using myHack | myFix so just put the patched AppleHDA.kext in there and move the original one from /L/S/E

sudo mv /System/Library/Extensions/AppleHDA.kext /System/

and run myFix (Quick mode)

So I got ML installed and ran the myHack however I have no sound or network. I'm trying to learn how to generate a DSDT but haven't been successful yet. Do I need to reinstall?

 

 

machine type: 4179w1f

 

 

 

Thanks....

No there's no point for reinstalling. Beside the HD (Low resolution) screen you have basically thesame hardware specs like I do. So again... rename the 4180A32 folder inside EFI/OEM/ to 4179W1F and use this dsdt: dsdt-143001.zip but change the DualLink to 0:

"AAPL00,DualLink",
Buffer (0x04)
{
0x00, 0x00, 0x00, 0x00
},

place the edited dsdt file in

EFI/OEM/4179W1F/ACPI/patched/

As for sound driver read post #30

I am doing this on my Lenovo T420 (Type 4178-6WU) with SN R8-Y2BLZ. I have tried different DSDT files as well. I keep getting hung on ACPI_SMC_PlatformPlugin::InitFanThrottleControl - Waiting for AppleSMC

What else am i missing. I am using a FAT32 USB with CLOVER2 and your EFI update from the first post.

Looks like FakeSMC.kext is not loading ... make sure you have it in:

EFI/kexts/10.8/ or in case you renamed my folder to your model name in OEM/41786WU/kexts/10.8/

Thanks for the quick reply. Same issue even with FakeSMC in both folders. I do have dual video cards on this verison. Could that be the issue?

The more information you give the better chance to resolve your issue.

- what OSX version you are trying to boot?

 

Update: Try disabling OEM table DMAR in Clover option during boot and report back

Today I've made a display override for my HD+ Panel (1600x900) based on MacbookPro9,1(DisplayVendorID-610/DisplayProductID-9cc7) and named it Lenovo LCD.

The display profile default is warmer using this file and I have added some extra resolution choices in scaled mode.

back to clover 1050 cos with 1090 i got that :

 

Yes I'm using Clover r1062 cause latest builds broke cpu detection (thus I get fuzzy sound) and graphics are messed up.

BTW1: what is the DeviceProperities string injection good for?

BTW2: whats your full serial number and hows is your CPU detected in 1050? (Is it 2.6GHz or 2.59GHz)

 

Nice little app for beginners that just want to add the "Display LCD" for the unknown panel. Thanks for bringing this up.

As pointed out in private message from Tetonne I have notice that iMessage is not working for our HacBooks and I think the key to resolve that issue is:

1. Ethernet binding to en0 (first network device)

2. Proper MLB serial number (17 digits)

 

I have enabled and disabled my iMessage account few times to check if its working permanently... and all just works :)

Hello!

 

Thanks A LOT for your post. The last laptop I hacked was a Dell notebook and that was 6 years ago, so I'm basically a newbie regarding the latest procedures to get OS X running. Things have improved dramatically for what I can see and the community is now strong and really vast.

 

After a series of unrelated events I've ended up really fed up with Apple and want to experience other hardware and fresh air but need and prefer to use OS X. I need a stable reliable system that's why I like very much the UEFI approach, it's clean and elegant, congratulations on the work done.

 

I shall be looking for a relatively updated second hand laptop, and my eyes were set on a Thinkpad since they seem solidly built and reliable. Plus I like the rugged 80's look... I must be getting old.

 

It looks like the job is really advanced on the T420... Would it work similarly on a x220 or is it a completely different beast? I like the screen resolution of the T420 but prefer the size of the X220.

 

One more question, are the T430 or the X230 theoretically approachable with this method or do you foresee some hardware obstacles that make the hack impossible. I'm trying to get the most stable and functional Thinkpad that is possible.

 

Regards and again thank you for your work, really appreciated.

He he yes I guess we are getting older cause I have a macbook pro but I prefer to use my T420 as my main hackbook computer :)

From the x220 spec I can see you will be good to go with the UEFI method (Sandy Bridge with Intel HD 3000) as for T430 and X230 I'm very optimistic cause I see more and more commits in clover that deal with Intel HD 4000 thus I see no reason why this shouldn't work.

 

To be honest I'm curious how will this work on other UEFI enabled ThinkPad's that is why I welcome all models specified below to join in and share their experience.

- what OSX version you are trying to boot?

 

Update: Try disabling OEM table DMAR in Clover option during boot and report back

 

I have tried disabling OEM table DMAR. That went further. I got to as far as the screen where it's asking for mouse/keyboard (bluetooth) which i had and then KP. I think it's the recovery screen and I got as far as being able to partition a new drive before it KP once.

 

I am running on Lenovo T420, i7 with 16GB of RAM and 256GB SSD drive. For the install media, I am using a 2GB standard USB stick formatted as FAT32 then Ran Clover with EFI option (not standard and both of the 64bit checked) on the latest clover. As for the OSX, I have a MBP 15" retina and I downloaded ML 10.8 on there thru the store. I made a 8GB boot USB with that.

 

Thanks for the help so far. Do you need any particular info. I am trying to get the message before KP but it keep rebooting before I can even write it down.

I see you have upgraded the RAM and HDD. Wait, you say 16GB of RAM is possible in T420!? Do tell more about the upgrade and what ram you are using.

 

You are getting closer... Dropping DMAR table will be essential for you cause you have new installer 10.8.2 (you will fix that later with AppleACPIPlatform.kext).

The KP is most likely your CPU - in clover try unchecking P and C states generation, than try SSDT table drop unchecked etc. Also experiment with different UEFI Bios settings (try using Intel HD 3000). Good luck and report back.

try Clover_v2_r1112 but went back to Clover_v2_r1050 cos i got that

 

 

Help would be great

i try to move dsdt.aml

no result

 

boot.log under 1050

under 1112

The systemlog says that you are running r1050 but anyways. (ok You have added the seccond one) :) 1112... This is because latest Clover builds are using DualLink enabled by default. Just disable it in config.plist and see if this helps.

I figured it out. It was the dropping DMAR and going to bios and turning off the NVIDIA optimus mode off. That took care of the whole install and all.

 

Yes I got the T420 about 2 years ago. So it was right as the T430 begin to come out. The motherboard can handle 16GB RAM. I am dual booting right now. One SSD (128) holds Win8. The 256 is partitioned in 2. Half for data shared between 2 OSes and half for OSX. Working good so far. I also got a small USB wifi module so that goes in the USB slot by the battery bay so it's out of the way. Just remember to turn of the power feature on BIOS.

 

Well, 3 things so far: 1:Not sure which format to use but clover is now installed on mac HD and still does not show up as bootable drive thru BIOS. 2:Audio is not working but I assume some kext is missing or needed to be modified. And finally 3: Everytime OSX is booted, Bluetooth keeps searching for Keyboard. Odd. Typing from T420 on Mac mode so it's good so far though. Thanks for all the help.

Niece to see you progressing with the setup.

 

The bluetooth "phenomena" is normal cause OSX doesn't accept PS2 devices as valid controllers (keyboard/mouse) and thinks that they aren't connected. Just disable the bluetooth check.

As for audio. You are most likely using wrong driver or missing one. Now that you have OSX running update your post with DarwinDumperReport available here.

Thank you Kogen Mantis, UEFI is a great way to go (and install). My 4236DE2 build is flawless (sound,sleep,display port) with a quick load (UEFI w/ clover IS quicker). Had to add a vodoo battery kext. After playing with several DSDTs I used manwe150's from the other T420 big thread with the "DualLink to 0"fix from post 32 (I have the low resolution monitor). Changed the folder name on EFI partition and bingo. I was getting that black screen before the dual link fix, although connecting an external monitor worked.

 

I simply swapped the drive to my wife's 420: 4177CTR. And all but sound works. No folder change. System profiler even shows her 16 RAM at 1600 MHz(GSkill) and a Firewire port. I can't wait to try the Firewire with a MIDI external soundcard I have.

 

My wife's is a refub but a hellava Macbook. One thing, I put win7 on another Partition and clover wont boot it. Even if the bios is only legacy.myKexts.zip

      - First version.
       
      What works and what does not
       
      - Processor: Intel Core i5-4300M ->  Work. All SpeedStep stages.
      - Video Card: Intel HD4600 ->  Work. QE/CI and Metal.
      - Chipset: Intel QM87 ->  Work.
      - Mini DisplayPort ->  Work. But no audio, yet.
      - VGA ->  Not work. Normal.
      - Audio: ALC292 ->  Work.
      - WiFi/Bluetooth: Intel AC 7260 ->  Not work. Replaced with DW1560 (need whitelist removal).
      - Ethernet: Intel I217-LM ->  Work.
      - Card Reader: Realtek RTS5227 ->  Not work.
      - Keyboard and Touchpad ->  Work.
      - Webcam ->  Work.
      - Fingerprint Reader ->  Not work. Normal.
      - USB3.0 ->  Work.
      - Sleep ->  Work.
      - Airdrop, Handoff, Instant Hotspot and Continuity ->  Work after replaced wireless.
       
       
      Extras
       
      - FullHD 1920x1080 display upgrade: 
      Replaced with AU Optronics B140HAN01.1 30pin eDP (B140HAN01.2 and B140HAN01.3 also compatible).
      Apparently same screen as Dell Latitude E6440, E7440, Lenovo Ideapad U430 and E129.
       
      - CPU upgrade:
      Replaced the stock Intel Core i5 4300M 2.6Ghz (3.3Ghz turbo) 6M cache with Intel Core i7 4700MQ 2.4Ghz (3.4Ghz turbo) 6MB.
      I initially had problems with overheating. The processor ran at full load above 90 degrees.
      After using a quality thermal paste I can work between 70 and 80 degrees.
      Acceptable taking into consideration that the new processor has 47TDP versus 37TDP which is recommended.
      I also had no problem consuming the battery while charging. The original 65W source seems to have figured out.
       
      - Touchpad upgrade:
      Replaced the stock with T460 touchpad.
      This is serious: you have to do it! It should be stock. Touchpad with precision and absurd quality!
      Just do it!
       
      - RAM upgrade:
      No mistery here. Just upgade.
       
       
      Todo
       
      - Make DP audio work.
      - Make Card Reader work.
      - Upgrade CPU to i7-4712MQ (Ordered. It's on the way) Done, but received i7-4700MQ (47w TDP, with good paste I have no overheating)
      - Replace touchpad with T460 model (Ordered. It's on the way) Done. Sensitivity and perception of quality much better. I recommend 100%!
      - Sierra Gobi5000 4G LTE modem EM7355 (Ordered. It's on the way. I hope works. ) Done, but not work. Recognize but not connect. I already gave up...
      - Upgrade to 16GB RAM Done
      - Make trackpad appear in System Preferences
       
       
      What you need to install

      - Running install of macOS

      Create install flash drive

      Open terminal and run this command:
      sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/Install --nointeraction This will take about 30 minutes.
       


      Install bootloader

      Download the CloverEFI from SourceForge (used 4934) and install with this options on "Install macOS Mojave":
       
      - Install for UEFI booting only
      - Install Clover in the ESP
      - UEFI Drivers - ApfsDriverLoader-64
      - UEFI Drivers - AptioMemoryFix-64


       
       
      Make things works

      Will be created a partition named EFI and mounted in Desktop.
      - Replace the /Volumes/EFI/CLOVER/config.plist with mine attached below
                    If you have modded BIOS with Advanced Menu and enabled 128MB DRAM-prealloc use 128MB_DRAM-prealloc_config.plist.zip
                    If no, then use 32MB_DRAM-prealloc_config.plist.zip
      - Put SSDT-L440.aml attached below in /Volumes/EFI/CLOVER/ACPI/patched/
       
      Generate your Serial, MLB and SmUUID
       
      - Open the replaced config.plist with Clover Configurator (used 5.3.2.0)
      - Go to SMBIOS, click few times in "Generate New" in Serial Number and SmUUID.
       
      Download those Kexts and put in /EFI/CLOVER/kexts/Other/
       
      - Download the HWSensors 3 from here. I used the FakeSMC.kext, ACPIMonitor.kext and IntelCPUMonitor.kext inside of DMG version r196.
      - Download the VoodooPS2Controller.kext from here. I used version 2018-1008.
      - Download the IntelMausiEthernet.kext from here. I used the version 2018-1031.
      - Download the Lilu.kext from here. I used the version 1.3.6.
      - Download the VoodooHDA from here. I used the version 2.9.1 and patched the sound volume (attached below).
      - Download the WhateverGreen.kext from here. I used the version 1.2.9.
      - Download the AppleBacklightFixup.kext from here. I used the version 2018-1013.
      - Download the USBInjectAll.kext from here. I used the version 2018-1108.
      - Download the ACPIBatteryManager.kext from here. I used the version 2018-1005.
       
      - Download the VirtualSMC.kext from here. I used version 1.0.2. Replaced with FakeSMC of the HWSensors 3 r196 package.
      - Download the FakeSMC.kext from here. I used the version 2018-0915. Replaced with VirtualSMC.kext due 10.14.4 issues on update.
      - Download the AppleALC.kext from here. I used the version 1.3.4. Replaced with VoodooHDA.kext due mic not working.
       
       
      Wifi and Bluetooth (DW1560 / BCM94352Z)
       
      Unfortunately, some notebook manufacturers are currently blocking the replacement of wireless cards. They want you to only use the models sold by them. And of course, none of them from Lenovo for this notebook model is compatible with MacOS.
       
      If you try to start with an unauthorized wifi card for them, you will receive a screen error:
      1802: Unauthorized network card is plugged in - Power off and remove the network card. Since this check is done directly in the BIOS, the only solution is to modify it.
      But since nothing is easy in this life, there is one small big problem:
      - The BIOS update procedure does not allow you to use modded files as it used to be.
      - You will need to physically reach your BIOS on the motherboard and make use of a USB BIOS reader/writer.
       
      So what you need to do:
      1. Disassembly your laptop;
      2. Dump your BIOS with an USB BIOS reader with SOIC8 clip (to not desolder from the motherboard);
      3. Patch it (In addition to removing the whitelist, add the advanced menu);
      4. Fix RSA signature;
      5. Reflash BIOS;
      6. Replace wireless card;
      7. Remount your laptop;
      8. Done.
       
      Soon, I'll provide step by step in this process. Probably until end of this week.
      In the meantime, if you need to, send me your dump that I do steps 3 and 4 for you.
      I also add the Advanced Menu so you can increase to 128MB the DRAM-prealloc.
       
      To fix a Modded BIOS to remove the 5 beeps on boot, you need this guide: https://www.insanelymac.com/forum/topic/337333-guide-fix-insyde-h2o-bios-signature-5-beeps-on-lenovo (traduzido: pt-BR)
       
       
      After replaced the wireless card. Download those Kexts and put in /EFI/CLOVER/kexts/Other/
       
      - Download the AirportBrcmFixup.kext from here. I used the version 2.0.0.
      - Download the BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext from here. I used the version 2018-0505.
      - Download the BT4LEContinuityFixup.kext from here. I used the version 1.1.2.
       
       
      Now you can start the instalation without problem (I guess).
       
       
      How install
       
      UEFI Setup Configuration and Installation

      UEFI configuration
       
      My BIOS is the latest: 1.93 (J4ET93WW) 

      - Shutdown and insert the flash drive.
      - Power on with F1 pressed to enter BIOS setup.
      - Change value: Config - Intel(R) AMT - Intel(R) AMT Control to DISABLED
      - Change value: Security - Security Chip to DISABLED
      - Change value: Security - Anti-Theft - Intel(R) AT Module Activation to DISABLED
      - Change value: Security - Anti-Theft - Computrace to DISABLED
      - Change value: Security - Secure Boot to DISABLED
      - Change value: Startup - UEFI/Legacy Boot to BOTH, Legacy First and CSM Support = Yes
      - Save & Exit Setup (F10)
       
      - Now, hold the F12
      - In the list, select your flash drive.
       
      The installer will start. 
      
      Format destination disk

      Format the disk with GUID partition mapping and name it "Macintosh".

      - Select Disk Utility in the list, then press Continue.
      - Click in View, then "Show All Devices".
      - Select the destination Disk, then Erase.
      - Name: HD, Format: APFS and Scheme: GUID Partition Map

      Close Disk Utility.
      
      Select "Install macOS", then Continue.
      Follow instructions in screen.

      After install

      After first part install the system will reboot. Maybe you have to press F12 again and select the flash drive.
      
      The second part of the installation will begin. This will take 16 minutes.
       

      Post installation

      Install bootloader
       
      When the second part of install finish, the system will reboot again.

      After performing the user initial setup and go to the desktop, you need to install Clover on internal disk.

      Open the Clover installer inside flash drive that you copied before.

      Use same options above but choose the system partition this time.

      Now you need to replace the EFI folder inside your destination disk EFI parittion, with EFI folder inside flash card EFI partition.

      If the flash drive EFI partition of your destination disk or flash drive is unmounted:
      Mount with terminal "sudo diskutil mount /dev/rdiskXs1". To know what X is, use "diskutil list", most likely is 0 for destination disk and 1 for flash drive.
       
      Then, eject the flash drive.
       
      Last step
       
      Move all Kexts from EFI partition to /Library/Extensions, with those commands in Terminal:
      sudo mv -R /Volumes/EFI/EFI/CLOVER/kexts/Other/* /Library/Extensions/ sudo chmod -R 755 /Library/Extensions sudo chown -R root:wheel /Library/Extensions sudo kextcache -i / Restart the system.
       
       
      It's done!
       
       
      Updates
       
      System update 10.14.3
       
      - Updated with success;
      - Everything works perfectly after reboot;
       

       
       
      System update 10.14.4
       
      - Updated Clover to 4910.
      - Updated Lilu.kext to 1.3.5 and WhateverGreen to 1.2.7.
      - After first reboot the update progress stoped with:
      GTrace synchronization point 4 Unsupported CPU Unsupported PCH hmm.. mismatch sizes: 3100 vs 20 It was still possible to start the previous installation, selecting "Macintosh" as opposed to "macOS Install" in Clover.
      So I created a flash drive with Clover 4910 and put only my config.xml, SSDT-L440.aml, the updated Lilu.kext and WhateverGreen.kext. And I decided to test VirtualSMC instead of FakeSMC.kext.
      With this I was able to install update 10.14.4. After installation I can boot normally, even with FakeSMC.kext that already in /Library/Extensions.
      I do not know what exactly happened, but now works everything like was previously.
       


       
       
      System update 10.14.5
       
      - Updated Clover to 4934.
      - Updated Lilu.kext to 1.3.6 and WhateverGreen to 1.2.9.
      - After first reboot the update progress stoped again (like 10.14.4 update) with:
      GTrace synchronization point 4 Unsupported CPU Unsupported PCH hmm.. mismatch sizes: 3100 vs 20 It was still possible to start the previous installation, selecting "Macintosh" as opposed to "macOS Install" in Clover.
      I decided to rollback to FakeSMC.kext but this time with the version of HWSensors 3. Link above.
      With this I was able to install update 10.14.5. After installation I can boot normally.

      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.
      “CONDIZIONI OBBLIGATORIE”
      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”.
      Immagine 
      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
      Immagine  
      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"
      Immagine 
       
      =====================
        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
      Esempio
      ===========================
      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.... 
      BENE…IL PROCESSO DI CREAZIONE E’ INIZIATO…
      AVREMO CIRCA 20/30 MINUTI DI TEMPO LIBERO A CUI DEDICARSI A CIO’ CHE VOGLIAMO………………………………………..  
      COLGO L’OCCASIONE PER FARVI NOTARE LA VELOCITA’ E LA SICUREZZA DI QUESTO METODO
      CONFRONTATE QUESTO CON IL TERZO METODO E NOTERETE CHE CON UN SOLO PASSAGGIO, OSSIA IL COMANDO DATO AL TERMINALE, FACCIAMO IN UNA SINGOLA OPERAZIONE TUTTI I VARI STEP DESCRITTI SULL’ ALTRO METODO.
      DETTO QUESTO, MOLTO IMPORTANTE E’ SOTTOLINEARE CHE COSI’ FACENDO EVITEREMO ERRORI  DI DISTRAZIONE RIGUARDO AI PASSAGGI O FRAINTENDIMENTI.

      Potete adesso passare ad installare il bootloader Clover sulla vostra usb.
      *NOTA*:
      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)
      ==========================
      Bootloader
      **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.
      Immagine 

       
      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

      ** Ricordate che avrete accesso a questa cartella dopo aver montato la partizione EFI**
      ===========================
      Per installazione Legacy
      Immagine 
      ===========================
      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”
      Immagine 
      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
      Immagine 
      5) Sezione BOOT: Sole se si sta installando Yosemite mettete il flag su kext-dev-mode=1
      Immagine 
      6) Sezione RT Variables: Se si sta installando El Capitan oppure Sierra, aggiungere i valori: BooterConfig= 0x28, CsrActiveConfig= 0x67
      Immagine 
      7) Sezione System Parameters: Su inject kext mettete YES
      Immagine 
      ===========================
      Nota: Su El Capitan, è stato introdotto SIP (System Integrity Protection)
      Info:
      ===========================
      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
      Immagine 
      
      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
