Lenovo ThinkPad T420 with UEFI Only

I used the updated t420 package and was able to boot from the USB.

On the T420, I installed over my old installation, and still have the issue of no display. If there was something in my old System folder causing this, wouldn't the installer have wiped out my old System folder? 

I guess the next step would be to wipe the drive clean and do a completely fresh install. Is there any way to access Finder from the booted installation USB, so that I can save any files I have on the system drive that I might want to keep? I am aware I can copy files around via the command line, but I'd rather not. My HD is an mSATA SSD, and I have no adapters for it, so I can't just pull it out and put it in an external. If not, would a live Linux distro be able to read the macOS drive?

i would try not injecting graphics with Clover first? did you try to increase brightness with SrcLck/Pause? i have been fooled by that.

I did a fresh install tonight, and all is well. I did find the newer zip you posted and used that for the last 2 attempts (the non-fresh and fresh.)

Before the fresh install while I was having the no-display issue, I did try the brightness keys. They would indeed adjust the brightness of the back light, but the screen was still displaying black. This was using the Fn+Home/End. I saw the Pause key mentioned somewhere and pressed that as well. Is Pause/SrLck a different brightness control? I also had tried the external DP displays on both the laptop and dock, but one thing I did not try was the VGA outputs.

But it's all good; I realized after poking around in Terminal for a bit that I had already backed stuff up to the secondary HDD in the laptop back when I first upgraded to High Sierra and thus didn't really have anything on the main drive to back up. I just wiped it clean and it was no big deal, just have to reinstall a few things. It would have been nice to figure out what the issue was in case it happens again, and future OS upgrades are still going to be scary on this thing, but I'll deal with them when the time comes.

I was also previously experiencing the occasional lock ups on both the T420 and T520, so it's good to hear that this has went away? Other than that, the only issues I have with them is with the occasional lines and artifacts in app windows, which I understand can be caused by low quality RAM? I'll have to swap a few sticks around and see what happens.

Thanks for the help and advice, not to mention the great guide for these machines!

@tluck Thanks for fixing it. It works for me now. I was able to install High Sierra on T420. What external wifi usb do you recommend? Will any work?

@copperspeed

there are several mac supported USB Wifi adapters. For example: I have one from ASUS N-10. and there are some other by RealTek (RTL), or TP-Link etc

So far so good. The blank screen thing did come back on one boot, but on the next reboot it was fine.

I've also had lockups yesterday and today. Both involved Safari, when clicking either the URL box or the tabs. There were times in the past where lockups were always while using Safari. Does anyone else have issues like this- lockups only when using Safari?

It kind of sucks- while I'm normally a big fan of the newer Firefox, Safari is zippy as hell when it comes to web apps I use for work. I'm going back to Firefox and see if I can make it through a work day without a lockup.

@tluck what's the deal with Clover these days ? It's been nearly 2 months since the last Clover update on Sourceforge, and only thanks to your Clover build I was able to install 10.13.4 on my spare laptop

@vusun123 - no idea why there isn't a recent build on SF? I just build my own package of course! how's things with you!? 

@copperspeed -  is your headphone stuck? i would perhaps put a headphone in and out a few times? I don't have low volume problem with my T420. what is your system - please create a profile in your signature.

Hi guys, using this guide and files for a while now in Sierra, all good , thank you very much!

However, I need to upgrade to High Sierra now (iPhone updated to 10.3 -> latest xcode version in Sierra can't work with that etc -> Need High Sierra and a newer xcode version).

I used AppStore to download High Siera. It did start the process of updating, but when I get to the part to select the HDD where to install it doesn't want to accept the HDD macOS I am using (Saying the it's missing the firmware partition).

I tried to follow the 2.3 steps from the guide to no avail. 

Also I don't understand the meaning of

"

  1. Manually mount and install of the ESP bits to disk0 by following the same procedure as for the USB.

"

Other that I tried everything I could think of. 

Thanks in advance!

Hi, I need your help.

yesterday I had to reinstall High Sierra on my T420. All is working fine with the latest Clover.zip package. But after wake from sleep my power led and sleep led on the cover keeps flashing.

Everything else works fine after sleep. I need to reboot, of course, for both leds to stop flashing.

 

Do you have ideal what can cause that? I have disabled hibernation and removed sleep image (hibernate mode set to 0).

OK I think I found the problem. For many years I had installed external disk in CD Bay instead of CD Drive. When I put CD Drive back, or just remove the external drive from CD Bay, led behaves as it should. So something is not right with the external drive sitting in the cd bay, then.

Hmm, I also have a HDD in my CD bay, maybe that is my problem. Oh and it's a m2 SSD in an adapter  that is in the CD bay and my macOS boots from it. I guess I should try switching the drive to the main bay.

Another strange thing is that I got a downloaded version of the installer (macOS 10.13.1) to try. And it does see the hard drive and starts the installation process, but when it restarts I choose the macOS install from the menu (Clover?) and after the Apple logo with the loading bar finishes loading, I get a the Prohibitory Symbol....

Hopefully this information will give more insights for the person who is willing to help.
Thanks!

Does anyone else get the occasional line flickering on the display? Also, has anyone else got a problem with the laptop not going into sleep when the lid is closed? I suspect that Mail is misbehaving, as it also prevents shutdown until forced to quit.

I get the line flickering and random lines and artifacts through windows that are open sometimes. I've read that it can be from poor quality RAM. I'm not sure what constitutes good vs. poor quality; I've tried switching RAM around between a few different brands, making sure to use the same kind of stick in both slots, but it didn't help. The same RAM works fine in Windows.

I find that it's predominantly in videos, including those on Facebook. Often consisting of one band but occasionally two running across the video. It does however also manifest in some other applications. I'm not sure if it's a RAM issue, appears to be more of a driver issue to me.

Hi all,

 

1.Is there an option to create bootable flash without using mac computer?

2.If i do not need wifi connection do i need to use modded bios?

3.What is the preffered bios version that  I can use on my laptop since for t420 I see version  from 1.46 and above but what about W520?

 

Thank you all for your great help and all information written here.

      Run Vanilla OS X El Capitan, Sierra, High Sierra or Mojave in VirtualBox 5.x.x on a Windows Host
      Following on from my previous guide on how to create a VMware virtual machine running Vanilla OS X El Capitan in Windows, I’ve decided to write a similar guide for creating a VirtualBox El Capitan VM. 
       
      The virtual machine should be useful for testing El Capitan and also for creating installers for use on a real machine/hackintosh.
       
      There are other tutorials and videos on the net about running OS X on Windows machines using pre-made VMDK disk images but you can never guarantee what else is in there….
       
      I’ve gathered info for this guide from several threads in the Multibooting and Virtualisation section of this forum and also the wider internet eg
       
      @colt2 HOW TO: Create a bootable El Capitan ISO for VMware
      @dsmccombs comment on faking Ivybridge Processor
      @E:V:A http://forum.xda-developers.com/showpost.php?p=55572430&postcount=6
      @Tech Reviews video tutorial https://www.youtube.com/watch?v=t7X07U63lwg.
      VirtualBox Forum: Status of OSX on OSX
       
      Requirements
         Intel PC with four or more CPU cores running Windows 7 X64 or later OS (2 or more cores needed for OS X)    4GB or more RAM (2GB or more will be needed for OS X)    Hard Disk with at least 40GB free for Virtual Machine    Oracle VM VirtualBox v 5.0.34    Install OS X El Capitan app and Mac or Hack to prepare installation iso <-- Now, no longer necessary to have previous access to a Mac or Hack by building the Installer.app from scratch - see post#75    16GB or larger exFAT formatted USB stick to transfer El Capitan iso from Mac/Hack to Host PC  
      Prepare Installation ISO on your Mac or Hack
      1.  On your Mac or Hack, download "Install OS X El Capitan.app" from the App Store into your Applications folder.
      2.  Download and unzip the CECI.tool (attached to this post) into your ~/Downloads folder. The commands in this executable script are shown below for informational purposes.  Note: you will need approx 16GB of free space on your hard disk for the script to complete.
       
       
       
      3.  Open OS X terminal, then run the following commands to execute the script:
      cd downloads chmod +x CECI.tool ./CECI.tool 4.  At the end of the process, you will have an El Capitan iso on your desktop - copy this onto an exFAT formatted USB for use on the PC Host later.
       
       
      Create an El Capitan Virtual Machine in VirtualBox
      1.  Open the VirtualBox program and click the "New" button to create a new VM.
       

       
      2.  Select Mac OS X and Mac OS X 10.11 El Capitan (64 -bit) for Operating System type and version.  I named my Virtual Machine "El_Capitan", then clicked next...
       

       
      3.  Leave the Memory size at the recommended 2048 MB, then click next.
       

       
      4.  Choose to "Create a virtual hard disk now", then click the create button.
       

       
      5.  For the hard disk file type, the default is VDI (VirtualBox Disk Image) but I have selected VMDK for inter-operability with VMWare.  Click next...
       

       
      6.  For Storage on physical hard disk, I have chosen the default Dynamically allocated (grows larger to a set limit as you need more disk space).
       

       
      7.  On the File location and size screen, you can set the location of the new virtual hard disk and its size - I recommend changing disk size to 40GB or larger.  When you click the create button, you will now see your new VM in the VirtualBox main GUI.
       

       
      8.  Click the settings button on the Main Menu to tweak a few settings....
         a.  On the System/Motherboard tab in Boot Order, you can uncheck the Floppy Drive (who has these now?)
       

       
         b.  On the System/Processor tab, you can increase the allocated CPU cores to 2
       

       
         c.  On the Display tab, you can increase the allocated Video Memory to 128MB
       

       
         d.  On the Storage tab, click on the icon of the Optical Drive and select "Choose Virtual Optical Disk File". 
       

       
      Navigate and select the El Capitan ISO we created earlier...
       

       
         e.  Click the OK button to finalise the VM settings.
       
       
      Patch El Capitan vbox configuration file with DMI Settings from a Mac
      1.  From the start menu, type cmd and click run as administrator to open an administrative command prompt. 
       

       
      2.  Choose a Mac Model similar to your host system, then type the following lines, followed by <enter>  after each line.  Make sure you first close all VirtualBox Windows and the VirtualBox program, otherwise any changes you make won't stick...
       
      Eg iMac11,3
      cd "C:\Program Files\Oracle\VirtualBox\" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-F2238BAE" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1 MacBookPro11,3
      cd "C:\Program Files\Oracle\VirtualBox\" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "MacBookPro11,3" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-2BD1B31983FE1663" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1 Macmini6,2
      cd "C:\Program Files\Oracle\VirtualBox\" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "Macmini6,2" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-F65AE981FFA204ED" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1 3.  Optional- For some host systems eg those with Haswell and newer CPUs, you might have to spoof an older CPU to avoid VirtualBox errors.  You can try from one of the following if this happens:

      To spoof Lynnfield i5 750 CPU
      VBoxManage.exe modifyvm "El_Capitan" --cpuidset 00000001 000106e5 06100800 0098e3fd bfebfbff To spoof IvyBridge CPU
      VBoxManage.exe modifyvm "El_Capitan" --cpuidset 00000001 000306a9 04100800 7fbae3ff bfebfbff or
      VBoxManage.exe modifyvm "El_Capitan" --cpuidset 00000001 000306a9 00020800 80000201 178bfbff 4.  Close the command prompt window.
       
       
      Installation of El Capitan
      We are now ready to start the El_Capitan Virtual Machine....
       



       
      Installation should be relatively straight forward, just following the prompts of the OS X installer:
      1.  Select language, agree to legal terms
       

       
      2.  Use Disk Utility from the Utilities Menu to erase and format the virtual hard drive as a single partition GUID Mac OS X Extended.  I named my drive "Macintosh HD" but you can enter whatever you like eg El_Capitan.
       

       
      3.  Quit DU and choose Macintosh HD to install El Capitan on.
      4.  After 20-30 min (depending on how fast your system is), the installation will complete.  At this point, unmount the El Capitan ISO by clicking the Devices menu from the VM window, click Optical Drives, then choose Remove disk from virtual drive.  The VM is now ready to reboot into OS X from the virtual hard drive.
      5.  At the welcome screen, choose your country and keyboard layout.  You can skip transfer information, location services and logging in with your Apple ID if you wish…
      6.  Create a User Account and select your Time Zone.  You can skip sending diagnostics and usage data to Apple….
      7.  Finally, you will arrive at the El Capitan Desktop.
       

       
      8.  Network/internet and audio should work OOB but on my system, the sounds were distorted.  Unfortunately, there is no QE/CI and the VM resolution will be fixed without the ability to dynamically resize the VM window (no VirtualBox additions for OS X guests atm). 
       
       
      Customization with VBoxManage
      1.  You can change the default resolution of 1024*768 (after shutting down the VM) with the VBoxManage command from the Windows Administrative Command Prompt:
      cd "C:\Program Files\Oracle\VirtualBox\" VBoxManage setextradata "El_Capitan" VBoxInternal2/EfiGopMode N (Where N can be one of 0,1,2,3,4,5) referring to the 640x480, 800x600, 1024x768, 1280x1024, 1440x900, 1920x1200 screen resolution respectively.
       
      Update:  For VirtualBox 5.2.x, the command for changing screen resolution has changed...
       
      VBoxManage setextradata "<MyVM>" VBoxInternal2/EfiGraphicsResolution XxY (where X=Horizontal screen resolution, Y=Vertical screen resolution)
      eg
      VBoxManage setextradata "<MyVM>" VBoxInternal2/EfiGraphicsResolution 1280x1024 2.  Adding serials and other SMBIOS details for the System Information Screen
      VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemSerial" "W8#######B6" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiBoardSerial" "W8#########1A" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemVendor" "Apple Inc." VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemFamily" "iMac" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiBIOSVersion" "IM112.0057.03B" A listing of known issues with Mac OS X guests can be found in the VirtualBox Manual - link https://www.virtualbox.org/manual/ch14.html.
       
      Vanilla Mavericks and Yosemite, Snow Leopard from Retail DVD
      The same VM settings for El Capitan will also boot and run vanilla installations of OS X Mavericks and Yosemite .  Attached to this post are installer scripts to create bootable Mavericks (CMI.tool) and Yosemite (CYI.tool) ISOs for VirtualBox and VMware.
       
      With the respective OS X installer apps in the Applications folder, download and run the installer tools using terminal ie
       
      To create a Mavericks ISO on your desktop
      cd downloads chmod +x CMI.tool ./CMI.tool To create a Yosemite ISO on your desktop
      cd downloads chmod +x CYI.tool ./CYI.tool Here is a screenshot of the VM running Mavericks 10.9.5...
       

       
      Finally, those without a Mac/Hack to prepare the install media can purchase a retail Snow Leopard DVD directly from Apple and install OSX 10.6.3 on their virtual machines (Snow Leopard, Lion and Mountain Lion run quite happily in VirtualBox with 1 CPU, 1-2 GB of RAM and the rest of the settings unchanged from above).  Once you update by combo update to SL 10.6.8, you can directly download El Capitan from the App Store for free .
       

       
      UPDATE macOS Sierra 10.12 to 10.12.6: For macOS Sierra, use CSI.tool in post#51.
      UPDATE macOS High Sierra 17A365:  For macOS High Sierra, use CHSI.tool in post#73.
      UPDATE macOS Mojave Beta:  For macOS Mojave Beta, use CMJI.tool on page 4 of thread.
       
      Good luck and enjoy

      Une petite mise à jour du topic pour confirmer le bon fonctionnement du patch à la volé de Clover (r3561) avec macOS Sierra.
       

       
       
       
      -----------------------------
      Mise à jour 24/08/2015
      -----------------------------
       
      ok, très bien,
       
      comme pour la HD6770, la nouvelle méthode du patch à la volé est de nouveau fonctionnel et avec les dernières versions de Clover.
       
      pour ma part, je suis sur El Capitan DB7 et Clover r3259
       

       
       
      par contre, je suis toujours obligé de m’aider de l’astuce avec FakeSMC pour que mes kexts soient toujours chargés, mais au moins cela marche.   
       
       
       
       
      et pour config.plist, cela donne ça :
       

       
       
      ceci est juste un exemple avec ma HD4830, il va de soi que vous devez mettre Device-ID de votre carte graphique !!!
       
       
       
       
       
      Salut à tou(te)s
       
      Comme certain(e)s le savent, les cartes graphiques dites "Exotiques" ne sont pas supportés par le système d'exploitation d'Apple.
      En sus d'ajouter l'identifient de la carte graphique (Device ID) dans l'Info.plist du ou des kexts concernés, il faut aussi interagir sur la partie "binaire" du kext par le biais du "patching".
       
      Dans notre cas, les cartes graphiques exotiques sont les cartes AMD (anciennement ATI) de la série HD 48xx, et plus précisément les HD 4830, HD4850, HD4870x2 et HD4890.*
       
      Donc le but est de faire fonctionner ces cartes graphiques de manière stable et fluide en activant QE_CI, chose nécessaire pour en profiter pleinement du système d'exploitation.
       
      * Juste avant de commencer, vous l'avez peut-être remarqué, la HD4870 n'est pas sur la liste suscitée et pour cause c'est que cette carte graphique est nativement supportée par le système d'exploitation d'Apple. Son Device ID est 0x94401002 que vous pouvez trouvé dans l'Info.plist des kexts concernés et c'est celui-ci que nous allons utiliser afin de le remplacer par le Device ID de notre carte graphique.
       
      ** Ce tuto est fait pour fonctionner sous OS X Mavericks, mais il doit fonctionner aussi avec les autres. La seule chose différente c'est l'adresse binaire à patcher.    
       
       
      Très bien, comme le titre le suggère, nous allons voir comment faire reconnaître ces cartes graphiques sous Clover et obtenir par la même un QE_CI activé et parfaitement fonctionnelle.
       
      Je vais utiliser ma Sapphire HD4830 512 MB GDDR3 PCI-E (comme cobaye    ) pour ce test et qui a pour Device ID 0x944c1002.
       
      Pour que ce test réussisse, nous allons donc utiliser ces 2 kexts, à savoir AMD4800Controller.kext (pour la partie QE) et ATIRadeonX2000.kext (pour la partie CI) et allons ajouter notre Device ID dans l'Info.plist. via le tweak "KernelAndKextPatches"
       
      Donc les valeurs à entrer dans notre config.plist sont celle-ci :
      <key>KernelAndKextPatches</key>     <array>         <dict>             <key>Name</key>             <string>AMD4800Controller</string>             <key>InfoPlistPatch</key>             <string>Yes</string>             <key>Find</key>             <string>0x94401002</string>             <key>Replace</key>             <string>0x944C1002</string>         </dict>         <dict>             <key>Name</key>             <string>ATIRadeonX2000</string>             <key>InfoPlistPatch</key>             <string>Yes</string>             <key>Find</key>             <string>0x94401002</string>             <key>Replace</key>             <string>0x944C1002</string>         </dict>     </array> Comme vous pouvez le voir, la clé "InfoPlistPatch" sert à injecter notre Device ID "uniquement" dans Info.plist, sans y toucher à la partie "binaire" de nos kexts. La clé "Find" a pour fonction de trouver le Device ID que l'on veut remplacer par le notre en utilisant la clé "Replace".
       
      Très bien, maintenant comme nous l'avons dit au début de ce tutoriel, ajouter notre Device ID n'est pas suffisant pour faire fonctionner pleinement notre carte graphique, il faut encore interagir sur la partie "binaire" de nos kexts. Dans notre cas, il va falloir agir uniquement sur un kext, çàd sur ATIRadeonX2000.kext et plus particulièrement sur ATIRadeonX2000.kext/Contents/MacOS/ATIRadeonX2000
       
      Et pour cela, nous allons faire comme ceci :
      <key>KextsToPatch</key> <array> <dict>     <key>Name</key>     <string>ATIRadeonX2000</string>     <key>Find</key>     <data>0F8394010000</data>     <key>Replace</key>     <data>909090909090</data> </dict> </array> Là nous pouvons voir que la clé "InfoPlistPatch" n'est pas utilisée et donc ces valeurs n'auront aucun effet sur l'Info.plist mais agiront uniquement au niveau de la partie "binaire". 
       
      Et voici les valeurs en leur forme complète que vous devrez ajouter dans votre config.plist
      <key>KernelAndKextPatches</key>     <array>         <dict>             <key>Name</key>             <string>AMD4800Controller</string>             <key>InfoPlistPatch</key>             <string>Yes</string>             <key>Find</key>             <string>0x94401002</string>             <key>Replace</key>             <string>0x944C1002</string>         </dict>         <dict>             <key>Name</key>             <string>ATIRadeonX2000</string>             <key>InfoPlistPatch</key>             <string>Yes</string>             <key>Find</key>             <string>0x94401002</string>             <key>Replace</key>             <string>0x944C1002</string>         </dict>         <dict>             <key>Name</key>             <string>ATIRadeonX2000</string>             <key>Find</key>             <data>0F8394010000</data>             <key>Replace</key>             <data>909090909090</data>        </dict>     </array> Très bien, maintenant il ne nous reste plus qu'à autoriser l'injection des kexts, sans quoi le patch ne fonctionnera pas. Et nous allons le faire via le tweak "InjectKexts" comme ceci :
      <key>SystemParameters</key> --> clé principale <dict>       <key>InjectSystemID</key>       <true/>       <key>InjectKexts</key> --> sous clé       <string>Yes</string> </dict>  
       
      Si certain(e)s d'entre vous préfèrent utiliser le logiciel "Clover Configurator" pour plus de facilité, voici comment entrer ces valeurs :
       
      Allez sur l'onglet "Kernel And Kext Patches" et faites comme ceci :
       
       
       
      *Ne faites pas attention sur le majuscule/minuscule, cela ne fait aucune différence
       
       
      Et pour injecter les kexts, aller sur l'onglet "System Parameters" et mettez l'option Inject Kexts sur Yes comme ceci :
       

       
       
      Voilà, vous n'avez plus qu'à enregistrer les ajustements, redémarrer votre pc et apprécier le résultat.
       
       
      MAIS ... seulement voilà ... il y a un problème ... 
       
      Quoi ? 
       
      Initialement, les kexts ne sont pas présents dans le kernelcache à cause de "OSBundleRequired=Safe Boot" (ils ne sont pas chargés en local par défaut mais en mode sans échec) et donc le patchage "à la volé" (on the fly) ne fonctionnera pas.
       
      Donc quoi, tout ça pour rien ?
       
      Non, bien-sûr, voici l'astuce pour remédier à cela :
       
      Dans un premier temps, il vous faut booter l'OS sans kernelcache. Si vous utiliser Clover Configurator, il vous suffit juste de cocher l'option "No Caches" dans l'onglet "System and Parameters" ou bien vous le faites directement dans votre config.plist :
      <key>SystemParameters</key> <dict>       <key>InjectSystemID</key>       <true/>       <key>InjectKexts</key>       <string>Yes</string>       <key>NoCaches</key>       <true/> </dict> Ceci aura donc pour effet de bloquer kernelcache et obliger boot.efi de charger le kernel et les kexts séparément. Clover et FSInject vont ensuite intercepter tous les chargements des kexts par boot.efi et changer "OSBundleRequired=Safe Boot" en "OSBundleRequired=Root" à la volé (on the fly) et forceront boot .efi à charger les kexts. Et ensuite dans un second temps, Clover va patcher l'Info.plist de ces deux kexts et la partie binaire de ATIRadeonX2000, kernel va les charger et ils seront rattachés à votre carte graphique.
       
      Une fois ceci fait (donc les kexts utilisés), il vous suffit de faire sudo touch /System/Library/Extensions. Ceci créera un nouveau kernelcache qui cette fois-ci contiendra vos kexts utilisés. Ensuite il ne vous reste plus qu'à redémarrer normalement (en décochant l'option No Caches dans Clover Configurator) et le patch fonctionnera à merveille.
       
       
      Oui, mais ... là aussi ...
       
      Quoi encore ?
       
      Seulement voilà, pour une raison ou une autre, il peut arriver que kernelcache se reconstruit tout seul et le patch "à la volé" ne fonctionne plus.
       
      Alors je fais quoi moi en attendant ?
       
      L'astuce la plus efficace pour le moment est d'injecter les infos de vos kexts à l'intérieur de l'Info.plist de FakeSMC.kext comme des IOKitPersonalities additionnels.
       
      ????Kézako????
       
      Ces infos vous les trouverez dans l'Info.plist de ces 2 kexts, sous IOKitPersonalities. Les voici :
       
      Pour AMD4800Controller.kext
      <key>Controller</key> <dict>         <key>ATY,Cardinal</key>         <dict>                 <key>aty_config</key>                 <dict>                         <key>CFG_NO_PP</key>                         <true/>                 </dict>          </dict>          <key>CFBundleIdentifier</key>          <string>com.apple.kext.AMD4800Controller</string>          <key>IOClass</key>          <string>AMD4800Controller</string>          <key>IOMatchCategory</key>          <string>IOFramebuffer</string>          <key>IOName</key>          <string>AMD4800Controller</string>          <key>IOPCIMatch</key>          <string>0x94401002 0x944a1002</string>          <key>IOProbeScore</key>          <integer>65050</integer>          <key>IOProviderClass</key>          <string>IOPCIDevice</string>         <key>aty_config</key>          <dict>                 <key>CFG_NO_PP</key>                  <false/>                  <key>CFG_PAA</key>                  <integer>0</integer>                  <key>CFG_USE_USCN</key>                  <false/>          </dict>          <key>aty_properties</key>          <dict>                  <key>PP_GFXClockGatingEnabled</key>                  <integer>1</integer>          </dict> </dict> Et pour ATIRadeonX2000.kext

      Et voici donc l'Info.plist de FakeSMC.kext dans son intégrité, vous pouvez jeter un oeil, histoire de voir à quoi cela ressemble :
       
      FakeSMC_Info.plist.zip
       
      Et pour les moins casse-têtes, voici FakeSMC.kext modifié que j'utilise pour charger les 2 kexts :
       
      FakeSMC.kext.zip
       
       
      Voilà, avec ceci, vous n'aurez plus besoin de savoir si oui ou non les kexts sont dans le kernelcache.

      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.
