@jus12 - cool. thanks.  i will try out your settings in a few days. i am in Puerto Rico on vacation without my T420 - so i cant test anything until i get back home.

 

@jenyunhuang - yes F8 (if you use the newer Key mapping) or PrtScr is supposed to turn off/on TrackPad - windows has a similar thing.

 

it the same VoodooPS2Controller kext as before but with different settings.  you can use the key mappings or not. but if you want to use the kexts in the older packaging thats fine too. there are differrent Info.plist options to switch behavior to suite your needs.

 

@NSCXP2005 - remember the Lenovo touchPad is not an apple (magic) TrackPad - so can do some 1,2,3 finger gestures and similar features because of RehabMan's kext/driver.''

@tluck after some more testing, I figured out that in general, writing into defaults works fine. The only missing point (for me) was the two finger double tap as right click (this can be enabled in the voodoops2trackpad.kext). So you cannot use only voodoops2trackpad.kext only, as if you disable the defaults clicking=0 nothing will work. I hope that makes sense.

Hey all just a note. For my Thinkpad t420 the keyboard did not work until after I installed and ran the kext install script. Not sure if that's intended but just a heads up. Don't give up. you may need a USB keyboard. Till after Install.

 

Also any progress on The Volume and Brightness keys working on Sierra? I'd offer to help but I don't know where to start.

After nice few days clean run on my macOS Sierra on W520 I got kernel panic:

 

any clues where can I start to investigate?

Hi all,

 

Is there any difference between the T410 and T420 apart from the nVidia dedicated GPU?

Hi jus12,

 

if I get your posts right, you have Sierra running with Nvidia and built-in display. Do you think you can share your settings (DSDT, config.plist, bios settings, EDID, display overrides, kext used)?

 

I'm running a W520 myself and only get a black screen when booting with discrete only. 

 

Thanks!

Yes. Everything. CPU, GPU, PM, Aspect Ratio. 

 

PS. You have a nice laptop to run osx

Tried to to an update from 10.11.6 to 10.12 (Sierra) via app store ... seems like that is a no go. Getting Kernel Panic after reboot ... seems like something related to VoodooPS2Controller ...

Hi @la0011, to get this work I only needed to change smbios to 10.1, I also disabled intel injection and enabled Nvidia injection in clover. After that all booted nicely, then I installed also NVIDIA alternative web drivers for Sierra (don't take the older driver for Sierra not the latest as that latest drivers don'w work).

Before the install I did upgrade Clover to 3811 and downloaded the zip but I only installed KEXTs via:

 

cd ~/Downloads/T420/EFI/CLOVER/kexts

sudo ./_kext-install.command

 

Then after reboot I went to app store and attempted to install Sierra. Restoring from backup currently, will give it another try. This time will use the clover that you have bundled in the zip and follow all the steps listed in post OS installation. Will report back with results later.

@roki303 -  

 

Sierra 10.12.0 is a bit buggy and not surprised there could be a random KP.  

 

getting the latest zip (and kexts) installed properly before installing Sierra is the right way to go. its a good practice to keep the same kexts both the /ESP (/Volumes/ESP/EFI/CLOVER/kexts/Other) and HD /Library/Extensions

 

Then the upgrade via App Store should work ok. I opted to install the Betas and they are working much better.

So after restore from backup I was able to progress a bit more. I did use the guide again to upgrade kexts and install clover. I also did VoodooPS2Deamon script that is in the same directory that kext_install script. I think that did the trick for me. I was able to upgrade to Sierra  via app store, log in, etc  but after successful install and first reboot I'm getting stuck on crossed out O sign and not able to boot. It boots into with -x -v flags. 

 

Progress but still stuck ... will play around with it a bit more see if I can figure it out but since my El Cap was flawless I'm actually leaning towards going back to that and wait a bit more for things to settle a bit.

Thanks jus12, I'll try disabling Intel injection, I don't think I tried that yet. SMBIOS is set to 10.1 as well.

 

But still, maybe you can share some more information. Did you set Bios to Discrete only or to Optimus? What DSDT are you using? Are you using the kexts provided here for the T420? Intel Backlight kext for example?

 

Maybe you can share your DSDT and config.plist?

 

I tried Nvidia Web drivers, but after restart I can't even open the Cconrol panel. Might be a seperate problem though. Which driver version is it you are using?

@budkin - i didn't use a USB keyboard when i upgraded from El Cap to Sierra.

 

i updated all my kexts on El Cap (in /Library/Extensions)

rebooted etc to make sure everything is in good order. 

then download the package to upgrade to Sierra

 

- but warning 10.12.0 is flakey. 10.12.1 should be out pretty soon - they released a Beta 5 recently. so you can see that are fixing a LOT of things.

 

recommend you create a recent working Clover-based OSX USB Installer in case you need to get to an OSX command prompt - can be El Cap. Say for example, you dont have a 2nd HD to boot from as a backup.

@tluck

 

the problem is I don't even have El Cap installed. I'm on Arch linux right now. Keyboard doesn't work in both Sierra's and El Cap's installers. I installed El Capitan using the archive from your post half a year ago and everything worked fine

@budkin - thanks for pointing that out.

 

 

i just posted a new zip - where I removed the symbolic links for Info.plist in Keyboard kext that do not work when installed in the ESP.  sorry.

 

now the for OSX installers - the PS2 keyboard will work (again) - just (re)validated.

 

not often needed - unless you need the command line!

if you usr dsdt to enable discrete graphics,,no need nvda_drv=1 and webdrive...i set  Bios to Discrete only

Thanks xtdd, how did you enable discrete graphics in dsdt? Can you share your dsdt/sdt and config.plist?

Hi everyone.

 
Sorry for my language but, unfortunately, I'm not good at English :(
 
My problem is jumping mouse when connected to the secondary monitor.
 
When two monitors (laptop and external) are enabled everything is ok.
But when I turn off the external monitor to work on the T420 screen - my mouse going crazy, lags, jumps etc. I turn back a second monitor - again, everything is ok.
 
I recorded a short video to present my problem.
 
 
Normally when I move the mouse cursor suddenly he lags by which interrupts and jumps on ...
 
What could be the reason?

@xtddd. Sorry I have no experience with with Discrete gfx on Thinkpad. In fact my general recommendation is to use integrated gfx unless you know what you are doing.

      Hola a todos, primero que nada estoy muy contento de a ver econtrado un foro de español sobre hackintosh.
      Mi problema consesite en que descargue unos drivers de esta pagina: https://github.com/chris1111/Wireless-USB-Adapter-Clover
      Seguí los pasos instale los kets en la carpeta EFI/CLOVER/OTHERS todo tal cual como dice ahi la instalación. luego segui los pasos de configurar la red dentro de configuracion del sistema etc.
      Lo cual el nombre me quedo en en0.
      El driver o kets funciona bien es reconocible por el S.O de hecho conecta la red, pero me dice que no tiene IP AUTO ASIGNADA Y LA OTRA QUE HAY UNA DESCONEXION A CADA RATO(como que desconectaras y conectaras el dispositvo usb a cada rato)
      Me gustaria que me ayuden con eso si es posible, Muchas Gracias!!

      I am making a minimal Clover build for the fastest boot possible with the boot6 file in legacy mode.
      While looking at the preboot.log, I noticed that there is a line without explanation (at 0:892). Apparently, whatever it is, the execution time of it is close to 2 seconds, more than 55% of the total logged boot time in the current configuration. This does not change whether I use USB 2 or USB 3 port.
       
      Is there a way to eliminate or speed up the above? Also, is there anything else you can suggest to improve the performance based on the below log file? Which moment in the boot process corresponds to the start time in preboot.log?  
      The last thing I would like to understand is the delay/timeout after the boot6 file has loaded, and the number 6 disappears from the screen. For about 2 seconds or slightly less, I can press any key, and then it will enter the BIOS-like interface from the boot6 file. Without further knowledge, it seems like those 2 seconds are just delay time, and only after that is CLOVERX64.efi actually started, which, I presume, is approximately when the preboot.log timer starts. So, if the aforementioned is correct, can I get rid of this delay as well? Note that I am using the boot1f32 file to chain-load boot6, which does not include the initial 2-second wait period for a keypress.

      Lenovo T460 macOS with Clover Guide
      Latest Release on GitHub (February 2020) Updated to Clover r5104 Updated Lilu based kexts - Lilu, ALC, WEG Updated acidanthera VoodooPS2 kext v2.1.1 the older 1.9 to the Misc Folder as an option.
        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.

      I used this command: diskutil info disk0s2 | grep -i "Partition UUID" | rev | cut -d' ' -f 1 | rev

      But I accidentally removed the wrong disk and now my main windows drive is not appearing in the bootloader. I can't figure out how to get it back. I tried resetting my windows drive, but I kept getting an error. I also reset my mac and reinstalled Catalina.

      Im having similar issue with my HS setup, dell latitute 3480, i5-7200U
      Once the hdmi plugged in, the laptop display went blank, only could see the external tv
      But, when i put my laptop to sleep & wake up again, both screen got display (hdmi still connected)
      Even the hdmi could be plugged off & in (after sleep), the laptop display is fine
       
      What could be the culprit?
