#2089272 Lenovo ThinkPad T420 with UEFI Only

Posted by tluck on 25 November 2014 - 06:41 PM

@xchlee - - a few questions:1) are you using your own DSDT? the DSDT i package is for the T420 not a T420S? there is a config.nodsdt.plist that you can try out to see if that gets you booted.2) is your disk MBR or GPT/GUID? can you boot using verbose to see where it stops (instead of seeing apple icon?). if you have the exact same EFI folder on the HD as USB - it is hard to understand why one boots and the other does not. @rolitab - the video is too low resolution to really see what you are describing. hmm. did you try setting your LCD to 50 HZ instead of 60?- the ripple effect to check quartz/ce - change System Preferences/Mission Control - to set Dashboard as Overlay. then add a widget in the dashboard. will ripple on addition - does not do this when "as space".

All - updated the bundle once again. Minor change but is about a regression to remove the drop MCFG table by default. Optimus users ... if want to drop that table for whatever reason, do so at your own discretion! 24-November-2014 UpdateClover r3029 - or download r3021.Consolidated kexts into Other folder vs 10.10, 10.9 since they are all the same.ThinkPad Theme - minor tweaks to add Yosemite 2014.  This theme revised and committed to Clover source tree.Updated select kexts - AppleHDA_20672.kext fixed for 10.10.2 dependency (works for 10.9. and 10.10)Removed drop MCFG table from config.plist files.Reason is I get this error when I drop MCFG table... which doesn't look good to me. so I prefer to leave the table and not get the error! Nov 24 12:23:11 Toms-Mac kernel[0]: ACPI_SMC_PlatformPlugin::registerLPCDriver - WARNING - LPC device initialization failed: C-state power management not initialized

The v3.1.2 kext was working for me on my H61-USB3 system on 10.10.0 - but now on 10.10.1 - v8111 ethernet - hangs after about 20 minutes of network traffic. will post some logs soon - but was wondering if others are seeing issues?

All - i just reposted the bundle - somehow the Other kexts were missing in the one from yesterday. sorry. after you install AppleHDA_20672.kext in /S/L/E Check the file  /System/Library/Extensions/AppleHDA_20672.kext/Contents/MacOS/AppleHDA test -L /System/Library/Extensions/AppleHDA_20672.kext/Contents/MacOS/AppleHDA && echo This is a sym-linkif you see "This is a sym-link" output then you are ok. Meaning, this file needs to be an actual symbolic link - not a text file with the filename in it.not sure what zip/unzip does this - mungs up the symlink do this is if not right:cd /System/Library/Extensions/AppleHDA_20672.kext/Contents/MacOSsudo rm AppleHDAsudo ln -s /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA .sudo touch /System/Library/Extensionssudo kextcache -u /The benefit was is really cool: able to upgrade from 10.10.0 to 10.10.1 with absolutely no kext changes. No need to post-install Audio and BT kexts - they just worked...

@osgaldo  do you have a way to connect the T420 disk to your Gigabyte system directly - like external USB ?if so, it's obviously  a lot faster to clone disk to disk with tools like Carbon Copy or just raw dd (vs say rsync over the network) I recommend UEFI boot for the T420 disk - which means format as GPT/GUID. I have generally moved away from MBR formatted disks and do not miss it! (i have one hybrid disk - GPT with MBR for VMware tho.) my OSX and Windows all boots nicely from a GPT disk -  i didn't have to reinstall windows. one trick is to dd (raw disk) the windows partition from an MBR disk to a GPT disk.  The just install the MS boot stuff in the EFI. Then you just have to run the microsoft repair to fix the BCD file in EFI and then life is good.  I just went through all this, as my dual-boot 750GB disk had some bad blocks had i just replaced it. So i wrote a script to reformat the new one using GPT (to avoid getting a MBR in place...

@adrenalation - if you have a logical root volume, i recommend revert to regular. thats seems to fix things for clover to figure out which partition to mount etc. run: sudo diskutil corestorage revert /

@sot_22 - well good news. I figured the x220 would behave the same as T420 for native NVRAM - i.e. without EmuVariable. @juxtaposse - you will need to take your keyboard out and replace your intel chip ... then you will have instant happiness! wifi does not work from the bottom slot (which is for mSATA and WWAN).

@stuppy et al, yes fusion71au is spot on.  there are plenty of posts about how to obtain and use the MLB and ROM values from a real mac. Thats what i did - and was happy to find out the working RtVariable method will not disappear.  I find the RtVariables very easy to implement. search imessage_debug. I posted some info in the T420 thread in my sig. and if you inject MLB/ROM it not change the model of your system at all.

Folks - Reposted the new zip today as I am not sure I got kexts updated right. sorry. 23-October-2014 UpdateClover r2967 - or stay on r2953 - it is still fine.Recompiled VoodooPS2Controller.kext v1.8.13 with added Lenovo T420 sections for Keyboard/TouchPad/TrackPointBumped the ACPIBatteryManager.kext up to v1.53Added Platforms.xml file for use with Docking Station (and No-Dock default) option in AppleHDA_20672.kextThis last thing is an option is to support people who have a Dock (Station). And perhaps not confuse the many who do not have a Dock. There are 2 files in AppleHDA_20672.kext/Contents/ResourcesPlatforms.xml.zlib.dock and Platforms.xml.zlib.nodock The "dock" version adds the 2nd audio output called "Headphones" and a 2nd Input "Line In" - both of which are on the Docking Station itself.IF you have a dock - then just replace the Platforms.xml.zlib file with Platforms.xml.zlib.dockIF you DO NOT have a dock, then...

@skoon432 - glad you are up and running again. sorry you had such a hard time.very surprising that the partition order matters. but ok. Perhaps when installing windows first, microsoft installation is doing something with the PMBR vs MBR and then confusing the OS X installer. are you booting windows via UEFI or MBR? I recall there are some tricks to make the DVD iso boot UEFI. I also remember making a separate UEFI USB installer for Win7.  anyway to answer your question: config.plist has a Boot section - to stop the countdown, change the boot countdown from 5 to -1see the clover wiki section for more info. @matthewpstro - glad you got it going. changed the instructions to say - reset to bios to defaults - and validate/set a few items! thanks.internal speakers - try plug/unplug headphones 2 times to see if output changes to Internal Speakers from headphones. (1 first output option - 2nd is dock)if you just see the overlay and don't hear any sound blips - make sure...

Posted by tluck on 22 October 2014 - 08:05 PM

T420 users:posted a new bundle with updates to 2 kexts. 1) ACPIBatteryManger.kext is now 1.53 (latest) 2) VoodooPS2Controller is still at v1.8.13  - however, I revised the VoodooPS2Controller kext to be consistent with RehabMan's stock version. Meaning, I kept all original default/alternate options in there but I added a Lenovo T420 sections that will pick up the DSDT PS2K variables LENOVO T420 to override defaults for the Keyboard, TouchPad and TrackPoint. This will allow you more easily tweak any variables that you might want to change. The current T420 section variables are just the ones that are different than the defaults - but you can add others to override. Note: if you are NOT on T420 or more specifically not using the DSDT provided with the PS2K mods, then you may want do a similar thing to add the PS2K DSM to identify your model etc. Thanks to RehabMan for building great tools! @myeyre - yeah the menubar sound widget will sync - but...

Posted by tluck on 21 October 2014 - 06:55 PM

@rajesheber  a similar thing happens on the T420 with an external monitor on DP when booting WITH the Lid closed. Then, if one opens the Lid, the LCD remains black  but powered.  If i boot with the Lid open with an external monitor and then I close the lid all is fine. can reopen without issue.  This behavior seems to be related to the presence of the ACPIBacklight.kext. Meaning if i remove that kext, then I can boot with the Lid closed with an external monitor. in this case, the LCD will show up ok when opened. i was meaning to ask RehabMan the developer of the ACPIBacklight kext, if he has thoughts about this. it may be that i have not properly implemented it on the T420? anyway, it was low priority since i usually boot with the LID open! so i guess there are 3 options:1) boot with LID open then close it after later.2) remove ACPIBacklight.kext to see if that makes a difference for you.3) see if others (such RehabMan) can provide s...
