#2100046 Lenovo ThinkPad T420 with UEFI Only

Posted by tluck on 03 January 2015 - 12:24 AM

@walid-wahthe built-in intel wifi will not work. you need to replace it with a OSX-compatible chip/card. there are a number of broadcom or atheros options. or you can get a USB version. @dreddtechwell you can make a new symbolic link and then rebuild the caches. do this:cd /System/Library/Extensions/AppleHDA_20672.kext/Contents/MacOSsudo rm AppleHDAsudo ln -s /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDAsudo touch /System/Library/Extensions

@ballistic - ok well then I suspect something is not configured properly (2 different revs perhaps?). IMO it seems easier (i.e. not having to sort out dependency and pre-requisites for network and audio kexts) to install all custom Kexts to the /S/L/E. Then have these same essential kexts (exact same copy from /S/L/E) on /EFI/CLOVER/kexts/Other readily available for situations where is not practical to install in /S/L/E such as the OSX Installers.   my gigabyte mobo is not very different than yours, but  basically I use 3 custom kexts - FakeSMC, RealTek Network, and Audio for ALC889.  (My AppleHDA-ALC889.kext must be installed in /S/L/E) here is my config.plist for reference: config.plist.zip 1.38KB 9 downloads my system log shows this for FakeSMC $ grep -i smc /var/log/system.logDec 31 13:14:14 localhost kernel[0]: FakeSMCKeyStore: startedDec 31 13:14:14 localhost kernel[0]: FakeSMC v6.14.1364 Copyright 2014 netkas, slice, usr-sse2, kozlek...

@all - i reposted a new bundle with clover r3108 - the change is I recompiled it to remove (annoying) text before the GUI.  @dauren - hmm not sure. you should have DP buffer/port available? are you using the zip/config.plist from my guide?can it find it on cold boot up? if you look at the kexts do you see these kexts$ kextstat|grep -i grap 77   15 0xffffff7f812ea000 0x47000    0x47000    com.apple.iokit.IOGraphicsFamily (2.4.1) <12 7 5 4 3 1> 78    0 0xffffff7f81bea000 0x2e000    0x2e000    com.apple.driver.AppleIntelSNBGraphicsFB (10.0.0) <77 12 11 7 6 5 4 3 1> 80    0 0xffffff7f81c77000 0x67000    0x67000    com.apple.driver.AppleIntelHD3000Graphics (10.0.0) <77 12 7 5 4 3 1> 97    2 0xffffff7f82011000 0x3000     0x3000     com.apple.driver.AppleGraphicsControl (3.7.21) <77 12 11 7 5 4 3 1>  119   ...

Posted a new bundle here: Clover UEFI on T420 Guide I started using VBoxHFS as it seems to be a tad faster.Note: the Clover installer will not replace HFSPlus-64.efi if present, so manually remove it if you would like to try the alternate driver. Happy New Year! 26-December-2014 UpdateUpdated to Clover r3094Updated FakeSMC.kext to v6.14.1364 for better Yosemite support  (included install pkg to install HWMonitor.app)Updated VoodooPS2Controller to v1.8.13 (has T420 configuration in Info.plist files - and is more consistent with RehabMan's code Branch)Updated ACPIBatteryManger.kext to v1.55 (to be consistent with latest rev)Using VBoxHfs-64.efi instead of HFSPlus-64.efi

@slice  i finally figured out what is causing VboxHFS.efi to list a bogus Microsoft boot option as compared to HFSPlus.efi. I recall Dr Hurt and others mentioning the same issue. well clover is not finding an extra bootmgfw.efi as suspected - it finds a leftover /boot file and just presents in the GUI (a no-op on click). this file is a legacy clover boot file from when I used to boot via MBR.  @warraisraw - as mentioned - move to clover and be done! getting intel speed step including turbo is generally a simple matter of SSDT and using the right product/model. like mbp6,1 or mbp8,1. - the i5 520m is a pretty common CPU in the 2010/11 era.  Yeah, I want find the problem or difference between both bootloaders, only for this I used Chameleon, for make a dump and compare with the Clover dump. Was only for not install all OS's again. The problem:Chameleon: Turbo FrequenciesClover: No Turbo Frequencies in addition to above suggestion... yo...

@jacekg -  easy to fix - the OSX installer likes to convert your disk into a logical volume. so just revert to regular volume by command line:the clover installer seems to get lost otherwise (i.e. looks at your disk1 and doesn't see EFI partition)sudo diskutil corestorage revert /

#2095284 OSX on DELL Vostro 3450 / Inspiron N4110 / XPS L702x UEFI Clover

Posted by tluck on 15 December 2014 - 03:44 PM

@sheepster - FWIW, the latest Clover packaged versions on SourceForge (2999-3050) continue to work just fine. (I'm actually on 3056 as i generally do a daily build) and all have been working great for me on similar HW (T420). One thing to mention perhaps, is recently the VBoxHFS driver was reworked and seems to work as well if not better than the HFSPlus.efi driver ... and in fact seems to be a tad faster.

@njdowdy 1) the VGA port on the T420 will work if you the config.plist i posted as it patches the frame buffers to use VGA instead of DVI on a dock station. the port is not auto sensing. so boot with VGA plugged in. i bought  a display port to VGA adaptor which is a bit more dynamic. 2) for windows UEFI installation: using Disk Utility to make a windows partition will convert the PMBR to MBR on GUID which confuses the windows UEFI installer. to make a partition for windows, i use gpt from the command line to add a windows partition.

@dr hurt.  are you using HFSPlus or VboxHFS efi drivers? seems like i had an odd entry with vbox and then after replacing it with HFSPlus.efi it went away.

#2090723 New Driver for Realtek RTL8111

Posted by tluck on 30 November 2014 - 09:25 PM

well ... good news seems to be coming (or here) with 10.10.2. i just installed the 10.10.2 seed and both Rehabman's (1.2.3) version and Slice's version (3.1.3) seem to be stable once again. obviously, i have not done a lot of testing.... but it played a video for about 25 minutes and then I switched drivers. Where as, when on 10.10.1 streaming the same video and in 5-10 minutes it hangs.

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?

Posted by tluck on 18 November 2014 - 02:36 PM

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...
