Nice, i managed to do it.  Thanks.  How would i go about doing the same on my x1 carbon 4th generation?

what type of graphics on that box? 

 

you can make a template for your system in the Panel_Backlight.plist my script. 

just hack the script to suit your box. 

 

there are 4 lines in that template file now.

4800 is intel HD4600

g780 is intel HD4000

T420 is intel HD3000

T460 is intel HD520 

 

each have 17 values defining a curve from zero min to max

Can somebody help me answer this question? I have a T460 (not T460s or T460p) that has Intel Wireless-AC 8260NGW. I see BCM94352Z (Dell DW1560) as the best-recommended replacement WiFi Card at various places. However, before ordering I wanted to ensure compatibility.

 

Per https://wikidevi.com/wiki/Dell_Wireless_1560_(DW1560) it seems to have a U.FL Antenna Connectors. 

But 8260NGW has MHF4 Antenna Connectors per https://wikidevi.com/wiki/Intel_Dual_Band_Wireless-AC_8260_(8260NGW)

 

So I wanted to know if people who have used DW1560 in their T460, did they use some kind of adapters for the antenna connectors or is the information wrong in wikidevi.com?

 

I also know that there's another variation of BCM94352Z (Lenovo 04X6020). This has MHF4 per https://wikidevi.com/wiki/Foxconn_T77H543.00 but seems to have a different socket connector.

 

8260NGW and DW1560 are like this...

04X6020 has like this...

i used BCM4352Z NGFF M.2 (aka Dell DW1560). i dont remember what the slot looks like.  to see if the 2nd cutout is needed or not to install the card. depending on the slot requirement, then maybe the 2nd card would work as well?

The 2nd cutout is needed. You can do it with a small jigsaw. There are a few who did it.

Be careful, it is your own risk.

I am using a org Apple WIFI BCM94360CS2 with adapter.

The bottom cover has a small dent, which I can live with.

Therefore the complete WIFI and bluetooth Kext and Patches are not needed.

Handoff, Continuity and Apple Watch unlock is working.

Sorry to respond so late but the x1 carbon has the same graphics as the 460 so i was able to do it on that machine as well. The only issue i have with my carbon is that even though it has an i7 6600u cpu, it still lags even with an nvme ssd whereas the 460 is running on a 500gb hard drive. I'm finally going to upgrade to an ssd on the 460 tomorrow when my ssd arrives. Hopefully i can upgrade to high sierra and then mojave from the app store.

I'm trying to upgrade the screen on my T460 to the high res screen.. Any particular screens i should be looking for? I'm looking at this particular one from ebay and the seller wants me to remove my current screen from laptop to compare the part number for compatibility.  I just want to do one job with  knowing one screen will work.

For some odd reason, my 460 doesn't seem to want to shut down from MacOs High Sierra. I could've sworn it worked from Sierra. Even when I try to turn off by pressing power button it restarts.

Do you have the USB Restartfix in place?

I recently bought this dw1830 over ebay. The card works but I'm wondering what is this black patch on the back side. The seller said its used item removed from another laptop but do you think it's some bad/quick fixing hidden behind the patch. I've not tried removing the patch because otherwise the card is working but I'm thinking of quick/dirty fixing which might reveal after some use.
Do you think I should take this up with the seller?


I'm saying this because something similar happened some time ago when I ordered a laptop keyboard from ebay. It said and looked brand new, worked well for couple of weeks and then went completely dead.

Hey @verleihnix I would like to take your approach of using the original Apple WIFI BCM94360CS2, I found this on eBay - https://www.ebay.ca/itm/Wireless-AC-Wifi-Bluetooth-Card-BCM94360CS2-For-MacBook-Air-13-A1465-A1466-GW/273112300004?hash=item3f96c2f9e4:g:iOAAAOSwn~JaqySc:rk:4:pf:0

I was wondering if this works and what adapter are you referring to? Something like this - https://www.ebay.ca/itm/BCM94360CS2-Card-To-NGFF-M-2-Key-A-E-Adapter-For-Mac-OS-and-Hackintosh/391512537270?hash=item5b27f738b6:g:wIEAAOSw42JZGAtx:rk:2:pf:0 It says on the description it doesn't fit on laptop so I was not sure.

 

Thanks!

Thanks @verleihnix for the link to the adapter and a picture of your laptop, I see it bulging out :) I think it looks very similar to the one I posted from eBay and AliExpress is cheaper so I'll order from it!

 

Question about the original Apple WiFi BCM94360CS2, would this be ok?

https://www.ebay.ca/itm/Wireless-AC-Wifi-Bluetooth-Card-BCM94360CS2-For-MacBook-Air-13-A1465-A1466-GW/273112300004?hash=item3f96c2f9e4:g:iOAAAOSwn~JaqySc:rk:4:pf:0

Sorry for asking so many follow up questions!

Just another compatibility note: T460/HD520 config works perfectly on my T470/I5-6500u, which also has intel HD520 graphics.

i just found this out on my T420 - that WhateverGreen kext may conflict with the AppleBacklightInjector kext. and if Whatevergreen wins then you may not have a display brightness slider. i will merge BackLight Injector stuff into WhateverGreen so it will not be a conflict.

Hi, I read your post and also https://octoperf.com/blog/2018/10/22/thinkpad-t460-how-to-install-macos/.
I'm using T460s (i7 6600u/16g/512g SSD/HD 520).
In others case, their screenshot of clover home screen, the first option is "boot macos install from install macos xxxxxxx", but my case is "start ueft shell 64", seems that clover does not recognize my macos disk partition.
Then I try to use "start ueft shell 64", but it only shows black screen without any response.
I already config the correct BIOS CONFIG, MACOS USB INSTALLER.The picture below is my macos USB installer, the first partition is EFI, the second is macos.

So can you help me with this?
Thanks a lot.

yes. worth a shot.  you can easily change in SSDT-PS2K-T460.dsl and recompile it.

Reinstall the kext to /L/E or to /EFI/Clover/kext folder

 

Hi tluck, verleihnix,

 

I'm also facing the same problems with trackpad. If I do quick swipes, the pointer doesn't move in proportion to the swipe but rather is very jerky (feels sticky). If I do slow swipes, then its ok.

I tried using the latest rehabman's version but exactly the same problems. I confirmed that Rehabman's version has all the corresponding T460 related changes (three buttons, clickpad etc.) so I'm continuing to use it but with your SSDT-PS2K-T460.

I'm using the latest v2018.10.12 release with T460 and the SSDT-PS2K-T460.aml has the BogusDeltaThreshX/Y=800. 

 

I resolved the jerky mouse pointer movement by

1. Commenting everything under "Synaptics TouchPad", Package() except "Thinkpad", ">y", in the SSDT-PS2K-T460.dsl, recompiling into .aml, replacing the previous one in EFI

2. Modify the Info.plist inside the kext by changing BogusDeltaThreshX/Y=800 (default values were 100)

3. Rebuilt kextcache

4. Mouse movement problem is gone, I can do quick swipes now

 

However, the scrolling with two fingers swipes is still jerky / sticky. Is there any documentation on the different attributes (like BogusDeltaThreshX/Y, ScrollResolution etc.) so that we can play with?

 

On a different note, why the kext did not account for the values in SSDT? Because the SSDT already had a Bogusxxx value of 800 and the mouse behavior was exactly the same in your latest voodoops2 kext as well as rehabman's version. The problem got only fixed by modifying the Info.plist inside the kext.

 

Secondly, is there a way unload / reload voodoops2controller kext or just the trackpad plugin inside it, so that I won't have to restart for testing different values?

I tried doing a "kextunload -b org.rehabman.voodoo.driver.PS2Trackpad" and my macos got reset. 

 

Thanks in advance for any help.

I using VoodooPS2Controller.kext from relase Lenovo-T460-Clover-2018.04.04 working fine with Mojave 10.14.2 .but any of rehubman's relase Voodoo version work well without use SSDT-PS2K-T460.dsl to make three buttons working.If use .dsl clickpad will lag with finger touch although three buttons are effecting.I tried many versions of SSDT-PS2K-T460.dsl but seems doesn't matter what contents inside all failed to improve this issue.My model is T460p with this problem when using rehubman's publish.Dose other three buttons user working fine?

Just a simplification note on configuration of my T470 (i5-6500U). 

 

Latest WhateverGreen (1.2.5) + Rehabman's base SSDT-PNLF enable backlight injection fine. slider and brightness keys work fine. 

 

Directions:

 

remove AppleBacklightInjector.kext from /Library/Extensions, add new WhateverGreen.kext, rebuild cache. 

 

build SSDT-PNLF.dsl and add to ACPI/patched (remove SSDT-PNLF-T460)

 

Modify config.plist per:

      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 1.1.9.
      - 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 config.plist inside your destination disk EFI parittion with config.plist inside flash card EFI partition.

      The flash drive EFI partition is unmounted. Mount with terminal "sudo diskutil mount /dev/rdiskXs1". To know what X is, use "diskutil list", most likely is 1.
       
      Last step
       
      Copy all Kexts from flash drive to /Library/Extensions, with those commands in Terminal:
      sudo cp -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;
       

       
       

       
      And last but not least

      [GUIA] Correção de assinatura BIOS Insyde H2O
       
      Recentemente comprei um notebook Lenovo L440 pra instalar o macOS Mojave e fui substituir a placa wireless pela DW1560 porque a atual não é compatível. Descobri que existia uma whitelist de placas permitidas que as fabricantes estão adotando recentemente (no meu caso utiliza uma bios Phoenix Insyde BIOS H2O).
       
      Procurei em fórums de BIOS MODDING e encontrei pessoas que fizeram o patch pra mim. Só que após substituir a BIOS notei que o computador ficava apitando 5 vezes todas vez que ligava e fui me aprofundar no caso. E foi aí que descobri como resolver isso e por isso criei esse guia baseado nas informações que achei em alguns fóruns russos.
       
       
      Prefácio
       
      Quando a BIOS falha no teste te integridade, algumas funcionalidades Intel AMT param de funcionar e é emitido uma sequência de 5 apitos duas vezes no boot.
      Após modificar para remover whitelist (habilitar placas WI-FI não autorizadas), destravar MSR 0xe2 (hackintosh), habilitar menu avançado, etc. a BIOS não vai passar no teste de integridade causando esse problema.
      Essa verificação de integridade é feita através da assinatura RSA do bloco da BIOS chamado TCPABIOS (mais informações abaixo) com a chave pública no formato modulus 3 também armazenada na BIOS.
      Esse bloco TCPABIOS armazena os checksums de cada volume da BIOS.
       
      O que faremos é gerar novos checkums para esses volumes que foram modificados, gerar um para de chaves RSA (privada e pública), assinar esse bloco com a chave privada e substituir a chave pública.
       
       
      Ferramentas necessárias
       
      - EFITool NE alpha 54: https://github.com/LongSoft/UEFITool/releases
      - HxD 2.1.0: https://mh-nexus.de/en/hxd/
      - OpenSSL: http://gnuwin32.sourceforge.net/packages/openssl.htm (Download -> Binaries)
      - Microsoft File Checksum Integrity Verifier (FCIV.exe): https://www.microsoft.com/en-us/download/details.aspx?id=11533
       
      Passo a passo
       
      Vamos abrir a BIOS modificada, localizar o bloco TCPABIOS e entender sua anatomia.
       
      1. Abra a BIOS no HxD
       

      (Vamos utilizar nesse guia a BIOS modificada no fórum MyDigitalLife.com pelo usuário Serg008 para o notebook Lenovo B590)
       
      2. Busque a palavra TCPABIOS:
       


       
      3. O bloco começa com TCPABIOS e termina com antes de TCPACPUH
       

       
      4. Anatomia:
       
      54 43 50 41 42 49 4F 53 48 31 38 34 61 31 31 2F
      32 36 2F 31 33 49 42 4D 53 45 43 55 52 00 FD 27
      34 2A 35 AB 41 26 39 E3 32 E5 B6 8A D6 49 5B 0B
      77 F9 82 58 48 00 00 00 CE 18 1F 00 00 00 03 00
      00 00 00 00 00 00 27 00 00 00 00 00 00 00 00 00
      00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
      00 00 00 00 00 00 00 00 00 00 00 FF FF 83 04 D4
      52 52 95 C5 D7 21 55 78 0E 5C AD 47 EE C4 3D 1D
      C1 EC 69 03 2B 51 A5 42 61 96 22 F9 7B 88 57 B7
      A8 9D D0 20 DB 5B 11 10 55 07 84 6C 62 DF FA 2F
      6A A8 43 0C 8A 40 AF 79 0D 31 DB 5A 5D C8 2F EB
      F8 7C 87 B0 A6 3D 2A 88 AE 91 9D 88 E3 AA 85 E3
      5A B3 91 7F 28 68 1F BA 92 C4 7E 10 F5 1A 7E 75
      A9 6F CE C0 4F BA FA 79 A5 98 2B 50 60 BA 09 73
      7B 03 D1 0C 3E A2 9C 44 DF E9 F2 92 34 7B
       
      Cinza: Nome e informações do bloco
      Vermelho: Informações dos volumes (Checksum e Cabeçalho)
      Azul: Separação da lista de volumes para a assinatura do bloco
      Verde: Assinatura do bloco TCPABIOS são os últimos 128 bytes
       
      Lista de Volumes:
       
      Cada volume tem o formato: 00 FD 27 34 2A 35 AB 41 26 39 E3 32 E5 B6 8A D6 49 5B 0B 77 F9 82 58 48 00 00 00 CE 18 1F 00 00 00 03 00 00 00 00 00
                                                      (prefixo 3 bytes + checksum 20 bytes + offset 4 bytes + tamanho do volume 6 bytes + separador do fim 6 bytes)
       
      Os volumes são enumerados e utilizam o primeiro byte no prefixo para isso (00 FD 27), começando do 0.
      A BIOS utilizada nesse exemplo possui somente um volume, mas no caso de mais de um volume, seria: 00 FD 27 .., 01 FD 27 ..., 02 FD 27 ...
      - Checksum é o cálculo SHA1 do volume.
      - Offset é a posição do volume dentro da BIOS. Os bytes ficam invertidos, nesse caso seria 00 00 00 48 ou seja: 48h
      - Tamanho do volume também está com os bytes invertidos, então: 1F18CEh
       
      Então é isso. Precisamos corrigir essas informações (checksum, offset e tamanho)
       
      5. Para extrair os volumes abra a BIOS com o UEFITool e veja como identificar os volumes (nosso exemplo há somente um volume, se houvessem outros estariam também dentro de EfiFirmwareFileSystemGuid):
       

       
      Na BIOS original, circulado em vermelho podemos ver o nosso volume.
      Observe que em azul temos Offset e verde o tamanho. Exatamente como verificamos acima no HxD. Já na BIOS modificada vemos que está diferente o tamanho:
      Oridinal: 1F18CEh
      Modificada: 1F12D5h (vamos precisar disso mais tarde)
       
      6. Vamos extrair esse volume escolhendo a opção “Extract as is...”
       
       
       
      7. Utilize esse comando para obter o checkum desse volume: fciv.exe -sha1 File_Volume_image_FvMainCompact.ffs
       

       
      Agora temos o checksum que é 396e0dc987219b4369b1b9e010166302ce635202
       
      8. Substitua as informações no bloco TCPABIOS:
       

       
      Observe que o tamanho do volume precisa ter os bytes invertidos, então se o total são 6 bytes e é 1F12D5h, fica D5 12 1F 00 00 00 no lugar de CE 18 1F 00 00 00.
      Se o offset for diferente, também realizar o mesmo procedimento invertendo os bytes.
      Checksum alterar de 34 2A 35 AB 41 26 39 E3 32 E5 B6 8A D6 49 5B 0B 77 F9 82 58 para 39 6E 0D C9 87 21 9B 43 69 B1 B9 E0 10 16 63 02 CE 63 52 02
       
      Faça esse procedimento para cada volume na BIOS.
       
      9. Agora precisamos gerar o checksum de todo o bloco TCPABIOS mas sem considerar os últimos 131 bytes, ou seja desconsiderar de FF FF 83 + 80 bytes da assinatura anterior.
       
      Copie para um novo arquivo no HxD e salve como tcpabios
       

       
      Utilize o comando para gerar o checksum desse bloco: fciv.exe -sha1 tcpabios
       

       
      Checksum do bloco TCPABIOS: 0da6715509839a376b0a52e81fdf9683a8e70e52
       
      Crie um novo arquivo no HxD e adicione 108 bytes com 00 e cole o checksum no final e salve como tcpabios_sha, ficando assim:
       

       
      10. Agora vamos gerar a chave privada RSA com modulus 3: openssl genrsa -3 -out my_key.pem 1024
       

       
      Assinar o arquivo tcpabios_sha: openssl rsautl -inkey my_key.pem -sign -in tcpabios_hash -raw > tcpabios_sign
       

       
      Agora aproveite para gerar a chave publica: openssl rsa -in my_key.pem -outform der -pubout -out my_key_pub.der
       

       
      E gerar modulus 3 da chave pública: openssl rsa -pubin -inform der -in my_key_pub.der -text -noout
       

       
      Copie e cole a chave em um arquivo de texto para utilizar daqui a pouco. Remova todos os “:” e coloque tudo em uma única linha, ficando assim:
       

       
      11.   Abra o arquivo tcpabios_sign no HxD, copie o conteúdo e substitua a assinatura no final do bloco TCPABIOS:
       
       
       
      12. Agora vamos localizar na BIOS o local da chave pública e substituir. Essa chave começa com 12 04 e termina com 01 03 FF e fica após o bloco TCPABBLK.
       
      A chave fica assim: 12 04 + 81 bytes + 01 03 FF. Faça uma busca por 01 03 FF para localizar mais facilmente. Verifique se antes dos 81 bytes tem os bytes 12 04 para ter certeza que achou.
       

       

       
      Agora substitua pela chave pública que ficou anotado no arquivo de texto anteriormente, ficando assim:
       

       
       
      Salve e está pronto. Sua BIOS está assinada e pronta.
