- Video Card: Intel HD4600 -> Tick.png Work. QE/CI and Metal.
- Chipset: Intel QM87 -> Tick.png Work.
- Mini DisplayPort -> Tick.png Work. But no audio, yet.

- VGA -> Cross.png Not work. Normal.

- Audio: ALC292 -> Tick.png Work.

- WiFi/Bluetooth: Intel AC 7260 -> Cross.png Not work. Replaced with DW1560 BCM94360CS2 (need whitelist removal).

- Ethernet: Intel I217-LM -> Tick.png Work.

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:

16GB (2x8GB). No mistery here. Just upgade.

 

- Wireless upgrade:

Previously I have the DW1560 working almost perfectly, now replaced with BCM94360CS2 that is full native supported. 

More info below.

 

Todo

 

- Make DP audio work.

- Make Card Reader work.

- Make trackpad appear in System Preferences

- Make Instant Hotspot work.

 

 

What you need to install

- Running install of macOS
- One USB flash drive of 8GB or bigger
- macOS Catalina install app
- Clover EFI

- Clover Configurator

- Some KEXTs and SSDT patches


How create create the install flash drive
 
Prepare install flash drive


Format the flash drive with GUID partition mapping and name it "Install".

- Open Disk Utility.
- Click in View, then "Show All Devices".
- Select the destination flash drive, then Erase.
- Name: Install, Format: Mac OS Extended (Journaled) and Scheme: GUID Partition Map

 

Create install flash drive

Open terminal and run this command:

sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Install --nointeraction

This will take about 30 minutes.

Install bootloader

Download the CloverEFI from official repository (used 5097) and install only with these options on "Install macOS Catalina":

 
- Install for UEFI booting only
- Install Clover in the ESP
- UEFI Drivers - Recommended Drivers - AudioDxe (Just to have nice sound on boot)
- UEFI Drivers - Recommended Drivers - FSInject (I still don't know if it's really necessary)

- UEFI Drivers - File System drivers - ApfsDriverLoader (Support to APFS partitions)

- UEFI Drivers - File System drivers - VBoxHfs (Support HFS/HFS+ partitions)

- UEFI Drivers - Memory fix drivers - AptioMemoryFix (Fix the memory management of de UEFI/BIOS)

 

FileVault 2

 

If you plan to use FileVault 2, you need to download additional drivers, since what comes with Clover is not up to date and use VirtualSMC instead of FakeSMC.

Follow instructions bellow:

 

From current Clover installation, check these options to USB keyboard/mouse work on password screen:

- UEFI Drivers - Human Interface Devices - UsbKbDxe

- UEFI Drivers - Human Interface Devices - UsbMouseDxe

 

After Clover install will be created a partition named EFI and mounted in Desktop. Usually the path is /Volumes/EFI/.

 

Download the versions 2.1.0 and 2.0.9 of AppleSupportPkg from: https://github.com/acidanthera/AppleSupportPkg/releases

We need the last version of AppleGenericInput.efi that is inside 2.1.0 and last version of AppleUiSupport.efi that is inside 2.0.9.

OR download attached bellow.

 

Put in /Volumes/EFI/EFI/CLOVER/drivers/UEFI/

 

That's it! FileVault 2 will work without problems.

 

 

1095967549_CapturadeTela2019-10-20as15_04_47.png.9a1d24b0ec40193e22826af623173ccd.png2133199866_CapturadeTela2019-10-20as15_04_50.png.7fa20729d6fef9acb4bf02bc7c6a4456.png195894321_CapturadeTela2019-10-20as15_04_55.png.8f0432527715441c03becf64a7661acb.png2029242469_CapturadeTela2019-10-20as15_46_33.png.3486be7485cadca2c3d5335b96cb5351.png

 

 

Make things works

 

After Clover install will be created a partition named EFI and mounted in Desktop. Usually the path is /Volumes/EFI/.

 

- Replace the /Volumes/EFI/EFI/CLOVER/config.plist with mine attached below

- Put SSDT-L440.aml attached below in /Volumes/EFI/EFI/CLOVER/ACPI/patched/

 

Generate your Serial, MLB and SmUUID

 

- Open the replaced config.plist with Clover Configurator (used 5.6.2.0)

- Go to SMBIOS, click few times in "Generate New" in Serial Number and SmUUID.

 

Copy the Clover Configurator to flash drive because you will need later.

 

Download those Kexts and put in /EFI/CLOVER/kexts/Other/

 

- Download the VirtualSMC from here. I used all Kexts and UEFI driver (put VirutalSmc.efi inside /Volumes/EFI/EFI/drivers/UEFI/) from version 1.0.8 (If you followed the steps to enable FileVault 2 above, skip to the next item).

Download the Lilu.kext from here. I used the version 1.3.8.

- Download the VoodooPS2Controller.kext from here. I used version 2.0.4.

- Download the IntelMausi.kext from here. I used the version 1.0.2.

Download the VoodooHDA.kext from here. I used the version 2.9.2. (Need to turn up the volume on Info.plist, more instructions below)

Download the WhateverGreen.kext from here. I used the version 1.3.3.

Download the USBInjectAll.kext from here. I used the version 2018-1108.

 

Important! If you are coming from my previous Mojave guide, please note that I am using some kexts from other repositories / authors.

 

 

Audio volume adjustment

 

- Open the Info.plist inside VoodooHDA.kext/Contents/ with TextEdit.app or any text editor of your choice.

- Change:

<key>PCM</key>
<integer>90</integer>

to:

<key>PCM</key>
<integer>140</integer>

Or, download the versions 2.9.2 attached bellow.

 

 

Keyboard swap Command with Option (optional)

 

- If you prefer, you can swap Command and Option keys, to map Win Key - Command and Alt - Option.

- Change /Volumes/EFI/EFI/CLOVER/OEM/S400CA/UEFI/kexts/10.15/VoodooPS2Controller.kext/Contents/PlugIns/VoodooPS2Keyboard.kext/Contents/Info.plist:

<key>Swap command and option</key>
<true/>

to:

<key>Swap command and option</key>
<false/>

Or, download the version 2.0.4 already adjusted attached bellow.

 

 

Wifi and Bluetooth (BCM94360CS2 + M2 NGFF adapter)

 

Recently I replaced the DW1560 with BCM94360CS2. Now I have fully wireless and bluetooth working (including Instant Hotspot) without any kexts.

 

See: 

 

 

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 (Ask on UEFI hack forums over there to someone patch for you. Every dump is unique, so mine don't work to you.);
4. Fix RSA signature;
5. Reflash BIOS;

6. Replace wireless card;

7. Remount your laptop;
8. Done.

 

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 /Volumes/EFI/EFI/CLOVER/kexts/10.15/

 

Download the AirportBrcmFixup.kext from here. I used the version 2.0.3. (To enable Wireless)

Download the BrcmBluetoothInjector.kext, BrcmFirmwareRepo.kext and BrcmPatchRAM3.kext from here. I used the version 2019-10-17. (To enable Bluetooth)

Download the BT4LEContinuityFixup.kext from here. I used the version 1.1.4. (To enable Handoff and Continuity)

 

Keep in mind that the bluetooth kexts are currently in development and the official releases will be available in future in the repository: https://github.com/acidanthera/BrcmPatchRAM/releases

 

 

Now you can start the installation 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.

Choose the flash drive (white icon).

 

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.
 

Choose the internal disk (gray hdd icon) if not already selected.


The second part of the installation will begin. This will take 16 minutes.


 

Post installation
 
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 make the system disk bootable.

Open the Clover Configurator from flash drive that you copied before.

Mount and open the flash drive EFI partition. (Inside Clover Configurator, Mount EFI -> Select flash drive in Efi Partitions list -> Mount Partition -> Open Partition)

 

Copy the EFI folder to desktop.

 

Go back to Clover Configurator, unmount the EFI partition of the flash drive and mount and open the EFI partition of internal disk.

 

Move the EFI folder from Desktop to EFI partition of the internal disk.

 

Eject the flash drive.

 

Move all Kexts from EFI partition of internal disk to /Library/Extensions and make kext cache, with those commands in Terminal:

sudo mv -R /Volumes/EFI/EFI/CLOVER/kexts/10.15/* /Library/Extensions/
sudo chmod -R 755 /Library/Extensions
sudo chown -R root:wheel /Library/Extensions
sudo kextcache -i /

Restart the system.

 

 

It's done!

Hi @Sergo_51, I really didn't understood you. Are you having problems with Bluetooth, is that it? You can use the BrcmPatch3 kexts like in my guide above:

Hi @Helda, my mistake!

 

My bios have MSR unlocked so I don't need the flag AppleIntelCPUPM = true, but a non-modded BIOS need this enabled.

 

I updated the config.plist in the guide. Change the flag with Clover Configurator or download the config.plist again.

Thanks for the guide! Successfully installed on my Lenovo L440.:)

However, there are a couple of questions:
1. How to connect a 4k monitor? When I connect the same monitor to this laptop on Windows or Linux, the resolution is 3840x2160 (60 hz), and here it is only 2560x 1600 (60hz)
2. The touchpad does not work at all. How to turn it on?

Thanks!

@ludufre, have you gotten OpenCore to work with L440? I'm wondering if it will be possible to run Big Sur on this laptop.

      Hello. I am experiencing a problem with my Catalina vanilla installation.
      My Dell 7567's screen is constantly blinking. This started in the installer and persisted after successful installation. Apart from the mentioned, the system is working perfectly fine.
      I am able to disable the backlight completely by pressing F11/brightness down button. I am barely able to see the on-screen text using a desk lamp afterwards.
      I have tried installing AppleBacklightFixup.kext, Lilu.kext and WhateverGreen.kext and setting my SMBIOS to iMac18,1 but none of those proposed solutions have helped me so far.
      To illustrate the problem, I have recorded a video (link) of my laptop booting into the installer and then shutting down. I have also included my CLOVER folder.
       
      I would appreciate any help or advice.

      Update: On October 24, 2020, using clover to solve the macOS11 beta10 boot problem, you can now enjoy macOS11beta10, and the compatibility of subsequent versions is not guaranteed.
      HIDPI uses a modified version. You can directly execute the hidpi script to get a better experience. If you lose the repair, it is not within the scope of my support.
      Support upgrades without destroying the integrity of the original image.
      There seems to be a problem with the shortcut keys. If you can help solve it, thank you for your contribution.
       
      Perhaps it was the first NEC (Lenovo) Lavie Z HZ550 to install hackintosh. I hope more people who like Lavie Z series can experience Hackintosh at HZ550. She is really great.
       
      I found HZ550 & HZ750 on the Chinese website, which is amazing. It weighs only 790g, 13.3 inches, and the standard 2k screen, which is too attractive to me. I am a Hackintosh enthusiast. I think HZ550 or HZ750 with MacOS is the best Unfortunately, the Lavie Z series is not listed in China, only exists in the Japanese and American markets, and in the Japanese market is the NEC brand, while the American market uses the Lenovo logo.
       
      Fortunately, I got an HZ550 from Taobao. Yes, not HZ750. In comparison, HZ750 has more touch screens and 360 ° flip. These are hard to attract me. More importantly, HZ750 is about 200g heavier than HZ550 That's why I chose HZ550. Well, because he is only 2,000 RMB.
       
      The specific introduction can refer to NEC Japan official website:http://nec-lavie.jp/products/hz13b/
       
      The HZ550 hardware list I obtained:

      Advantages: small size, light weight, 2K screen, 8G memory, 512g SSD, keyboard feels good, and wireless network card can be replaced, which is unimaginable in today's thin and light books.
      Disadvantages: The sound is small, almost the same as the mosquitoes.
       
      Ok, bragging is over!
      In order to use the wireless network, I changed the wireless network card from inter 7265 to BCM94352ZAE. Some people called it DW1560. It is uncomfortable that in China, this card and his elder brother DW1830 were hyped to a high price of 480RMB. of. Fortunately, I bought it early, and this card is also very stable under win10, and there is no high delay and outage. The hard disk should be PM951 of Samsung, not PM981, which is lucky.   Before installing Hackintosh: You need to prepare a 16G U disk, SanDisk is not a rough choice for making MacOS installation disk, I used the latest MacOS Catalina 10.15.5, got config.plist from Rehabman, and put together an EFI, the latest version of clover and kext drivers. Thanks to Rehabman and the developers of the Black Apple community. I do n’t like that OC team very much.
      Make an installation disk: If you have a computer running MacOS, you can use the command line to make it, if you do n’t have a computer running MacOS, you can try VMware, I know that the insanelymac forum allows discussion, or use ether to write the image to U disk, use the EFI I provided to boot into the installation process.   BIOS setting: Press F12 at boot to enter the BIOS settings, Tab switches to "Security-Secure boot", set to "DISable", this is what we need, and switch to "Boot -Boot devices", set the U disk as the first boot item You can directly enter the clover guide interface, please follow it for google it.
      It is worth noting that the remaining space of your EFI partition needs to be greater than 200M, otherwise, the disk format will be wrong. In addition, the format partition format is APFS, do not choose to encrypt, your data is not valuable, at least you must have this awareness of Hackintosh, the file safe is also the same, do not enable, do not use to find your mac, otherwise, change the machine, OK .   Fortunately, no additional ssdt patch is required. All the patch functions are implemented through clover. The flat Apple is turned on. This is to solve the problem of the flower screen. You can find a solution yourself.
      Experience your black apple, this will bring a better experience than MacBook Pro.

      I have been trying to get my Lenovo G570 i5 2430M with HD3000 (id: 116) to work for almost 2 months. Mountain Lion works flawlessly but Mavericks onwards, display stays off with the exact same setup (Chameleon: Extra folder with smbios mbp8,1 included in attachment)
       
      I'm able to boot and see the screen with remote desktop but internal display stays off.
       
      found an old post which fixed issue for few users
       
      I understand HD3000 is natively supported till High Sierra, which is why I'm totally baffled and out of ideas to proceed with.
       
      Any help is greatly appreciated
      Thanks

      In this thread, I have fully documented the installation of macOS Catalina on my HP EliteDesk 800 G4 Mini. It is a PERFECT HackMini8,1 and is running very well for me without any issues. I hope this documentation helps you to install macOS on your hack. Please leave feedback if you think there is anything I can improve and let me know if you have any questions.
      **********************************************************************************
       
      Background
      This is my first "modern" hack supporting UEFI and my first hack using Clover "on-the-fly" patches.  My previous hacks
      Laptop: Thinkpad T61 / Nvidia NVS 140m Laptop: Dell Latitude E6410 / Nvidia G3100m Desktop: Gigabyte G31 / GeForce 9600 Desktop: Biostar TH55HD / Sapphire Pulse RX580 (Google "Catalina Biostar TH55HD" and look for user name deeveedee)  
      are all perfectly running Catalina and I patched them all "manually" - all DSDT patches applied with MaciSL with virtually no Clover on-the-fly patching and all booted Legacy Clover.  This UEFI hack was MUCH easier and took about 20 hours vs. a combined hundreds of hours for the old hacks.  I wanted a hack that was a little more future proof and I think this is it.  I hope you enjoy this as much as I am enjoying it.  It is a perfect MacMini8,1.
