My fans are quiet on Sierra with my T420s i7-2620@2.7GHz. Maybe dust on the fans?

 

@pcace there is a option/fix to fan speed/heat. instead of relying on the bios to change fans speed which only seemed to run at 2 speeds. The "heat-step" DSDT versions has modified method to change fans speed depending on CPU temp - this requires using it + ACPIPoller.kext - both outlined in the Guide. you can modify temp triggers to match your needs - but there are 7 levels if I remember.

Hey there!

 

thank you again and again for your great work here!!

I kind of missed the point here ;) i am using the heat-step dsdt. And it is kind of working. I just realized, that under windows the fan can go up to 6500rpm. And i really would love to see that behaviour on the mac too. Not everytime, but when i am using this T420 in very hot environments... ...i do get scared, that i could ruin the machine - working at +100°C for hours and hours...

 

Any idea how to achieve that?

 

Cheers and thanks!!!!

 

PS.: i do know about this here: 

/* FAN control START */
                        If (LGreaterEqual (Local0, 0x55)) // CPU Temp is >= 85C
                        { Store (0x07, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 7 - Maximum Speed 
                        Else {
                        If (LGreaterEqual (Local0, 0x50)) // CPU Temp is >= 80C
                        { Store (0x06, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 6 
                        Else {
                        If (LGreaterEqual (Local0, 0x4B)) // CPU Temp is >= 75C
                        { Store (0x05, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 5 
                        Else {
                        If (LGreaterEqual (Local0, 0x46)) // CPU Temp is >= 70C
                        { Store (0x04, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 4 
                        Else {
                        If (LGreaterEqual (Local0, 0x41)) // CPU Temp is >= 65C
                        { Store (0x03, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 3 
                        Else {
                        If (LGreaterEqual (Local0, 0x3C)) // CPU Temp is >= 60C
                        { Store (0x02, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 2 
                        Else {
                        If (LGreaterEqual (Local0, 0x01)) // CPU Temp is >= 01C
                        { Store (0x01, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 1 - Lowest Speed 
                        }
                        }
                        }
                        }
                        }
                        }
/* FAN control END */

But it seems that Fan Mode 7 is around 4500rpm. Wich is not the fastest it can go...

 

cheers

Hey, just a quick answer (+ question) to my last post. 

 

i did look at a acpi patch for controlling fan speed on linux and found out, that there are 2 more modes to 0-7. 

there is also mode 64 and mode 128. mode 64 is supposed to be "disengaged" mode, mode 128 is "auto" mode. 

if i try to use either one of them, nothing happens. 

so what i did is, open up my dsdt.dsl (former name dsdt.heat-step.dsl) in the efi/acpi folder with maciasl and swiched the line: 

                        If (LGreaterEqual (Local0, 0x55)) // CPU Temp is >= 85C
                        { Store (0x07, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 7 - Maximum Speed 
                        Else {

 

to 

 

                        If (LGreaterEqual (Local0, 0x55)) // CPU Temp is >= 85C
                        { Store (0x40, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 7 - Maximum Speed 
                        Else {

 

saved it as aml, rebooted but nothing happens (yes, i am using the acpi kext in /Lib/ext..... Is there any reason why i would not be able to engage this mode??

here are some links:

https://forum.thinkpads.com/viewtopic.php?t=107512

https://www.thinkwiki.org/w/index.php?title=Code/ibm-acpi-0.11-2.6.13-fan.patch&action=raw&ctype=application/octet-stream

 

Cheers and THANKS!!!

 

 

EDIT: I dont quite know what happened, i did some reboots and now it is working!?

the aml is looking like that now: 

/* FAN control START */
                        If (LGreaterEqual (Local0, 0x55)) // CPU Temp is >= 85C
                        { Store (0x40, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 7 - Maximum Speed 
                        Else {
                        If (LGreaterEqual (Local0, 0x50)) // CPU Temp is >= 80C
                        { Store (0x07, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 6 
                        Else {

                        Else {
                        If (LGreaterEqual (Local0, 0x3C)) // CPU Temp is >= 60C

                        Else {
                        If (LGreaterEqual (Local0, 0x01)) // CPU Temp is >= 01C
                        { Store (0x01, \_SB.PCI0.LPC.EC.HFSP) } // Set FAN Mode 1 - Lowest Speed

                        }
                        }
/* FAN control END */

Thanks!!!

You have T420, right? Where did you get your keyboard config file? Could you upload it here please?

Yes, got the same files... but no response from Play/Pause/Stop keys. Also I have brightness on the ScrLk and Pause keys...

How can I reset the files? Install the kexts again?

@freddie

FN+arrows give me iTunes back/play/forward

install the lastest VoodooPS2Controller from the zip.

and if you replace the SSDT-T420-PS2K.aml with the SSDT-T420-PS2K-keys.aml

and these keys will do the same.

thanks tluck, I have re-installed VoodoPS2Controller.kext with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], but still nothing. do I have to set something in the config.plist? (sorry for the noob questions)

do you have the DSDT and SSDT from the zip in place too? 

 

I've just went through your guide here at insanelymac. Where should they be?

Thanks!

Sorry tluck, I've expressed myself wrongly.

I have followed your guide to install hackintosh on my T420s, but I don't know how to install/configure these DSDTs or SSDTs you are talking about... I see the ones for the keyboard on my EFI folder, but I'm not sure if they are wel configured or installed. Do I have to use Clover Configurator?

@freddie 

 

the ACPI files are in the EFI/CLOVER/ACPI folders 

clover reads ACPI/patched/DSDT.aml and SSDT*aml

the SSDT updates/sets a variety of values for the keyboard and TrackPad - so you dont have to edit the kext.

and there is a newer SSDT (in ACPI not ACPI.t420s) to remap keys to make it more like a real mac - called SSDT-PS2K-T420-keys.aml (and the source .dsl) file

these ACPI files have 2 identifiers - LENOVO and T420 to match the DSDT/SSDT and the properties in VoodooPS2Controller.kext.

 

Note: i dont know if the keyboard is different on a T420s vs T420. and it would help if you listed your system in your signature. i dont have a t420s so i dont update the ACPI.t420s files. but they are somewhat consistent.

Hi @tluck

Thank you very much for your efforts

 

I have E560 and I found this topic

https://www.tonymacx86.com/threads/stable-lenovo-e560-full-work.248842/

 The guy use your T460 file to make E560 working

 

I have the same E560 but I have a different CPU and I don't know if I should do any changes to his files?

And I should I make my own files like DSDT and SSDT and config.plist and do the patchs?

if so how to do that?

 

I am sorry to ask you about another laptop but I will be very grateful if you could help me

Well, I tried the different SSDTs but none of them made the Play/Pause work.

 

I've used Karabiner-EventViewer to see what happens when I press these keys, and there's no event being recorded... don't know what to do :( Is there a way to remap these keys?

Are you sure that this key isn't broken on your keyboard? Strange that certain special functions work but not this one.

      Hi, I'm kind of lost when scrolling to Clover Configurator, so I decided to use an EFI from the web and just configure the most basic stuff. But that sadly didn't work, im always getting the attached screen IMG_0054.HEIC (and I don't know whether all the errors are listed, as I can't scroll). 
      Anyways I thought it'd be better to do a custom setup. Can anyone give me some help with what to choose in the settings? Here's my rig:
      i7 8700k
      Asus z370-G (Rog Strix)
      gtx 1060 6gb
      samsung ssd (SATA)
      WD hard drive
       
      Your help would be much appreciated!
    • By kylon
      A big thanks to wegface for teaching me a lot of things.
       
       
      Tested on Catalina 10.15.4 and Clover EFI 5104 (Catalina Patcher)
       
      Not Working:
      - realtek sd card reader (pm me if you have a fix)
       
      Notes:
      **CPU patches are disabled, if you are using a locked BIOS you must enable them**
       
      Clover EFI:
      - Install it in UEFI Mode and change your hdd partition table to GPT.
      - You will be able to install ANY OS in EFI mode, even if this pc does not support EFI at all! (No guide available for this)
       
      You will need:
      My unlocked BIOS (OPTIONAL) (here) Latest Clover config from CCE Bank (here) (asus k53sj-kylon) Rehabman Voodoo PS2 Controller (here) acidanthera AppleALC (here) acidanthera Lilu (here) acidanthera VirtualSMC (here) acidanthera SMCBatteryManager (here) acidanthera SMCLightSensor (here) acidanthera WhateverGreen (here) Mieze Realtek RTL8111 (here)

      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 BCM94360CS2 (need whitelist removal).
      - Ethernet: Intel I217-LM ->  Work.
      - Card Reader: Realtek RTS5227 ->  Not work.
      - Keyboard and Touchpad ->  Work.
      - Webcam ->  Work.

      - Sleep ->  Work.
      - Airdrop, Handoff and Continuity ->  Work after replaced wireless.
      - Instant Hotspot ->  Not 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.
       
       

       
       
      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)

      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.

      Lenovo T460 macOS with Clover Guide
      Latest Release on GitHub (March 2020) Updated to Clover r5105 Updated Lilu based kexts - Lilu, ALC, WEG Added AirportBrcmFixup.kext
        Various Tweaks over Last months The zip file is a complete Clover ESP (/EFI) bundle and kext pack for the Lenovo T460. The current file bundle is tested on Sierra. 
      Note: I never got the GFX fully working on El Capitan. 
      Full Clover file set - config.plist etc. Includes all custom kexts Includes custom DSDT/SSDT scripts and patches Utility scripts The zip bundles are posted to GitHub: https://github.com/tluck/Lenovo-T460-Clover/releases
      Caveat: The T460 systems used here was configured with: i5-6300U, Intel HD Graphics 520, 1920x1080 touch screen. If you have a different system model, then extract the ACPI files and use the included scripts to create a set of files consistent with your system type and BIOS version. See below for details.
      Credits: RehabMan, Shmilee, vusun123, TimeWalker, Mieze from which, much of their work and help is/was was used to get the T460 to this point.
      Devices and aspects working:
      Ethernet -  Intel I219LM is enabled via IntelMausiEthernext.kext WiFi/BT - substitute the Intel WiFi/BT with a compatible Broadcom or Atheros chip Audio - ALC293 codec implemented via AppleALC.kext (the old AppleHDA_ALC293 and CodecCommander kexts are not needed) PS2 - ClickPad + TrackPoint + all 3 buttons - using a modified VoodooPS2Controller to support new layouts - and added some custom Fn key maps based on 440/450 dsdt USB - implemented via custom SSDT + USBInjectAll kext. All USB3/USB2 ports are intel-based and work -  3 external USB and internal Camera, BT, etc  Sleep/Wake - the sleepwatcher package and custom sleep/wake scripts are used to help with sleep/wake for BT and PS2 devices. Note: have not tried to implement the SD card reader - no driver found.
