#2244310 Lenovo ThinkPad T420 with UEFI Only

Posted by tluck on 18 June 2016 - 07:26 PM

on occasion (often), i get a dead trackPoint on boot up. meaning the red knob doesn't  move the pointer or top buttons don't work. The trackpad and lower buttons do work. However,  a sleep/wake cycle will turn the trackPoint items on. but now with the newer kext, the trackPoint is working on startup very consistently.  i will post a new bundle with this new kext. 18-Jun-2016 UpdateUpdated to Clover r3566Updated FakeSMC kexts (and included installer for HWMonitor.app)Updated VoodooPS2Controller kext to latest rev

@mr_yellow - that's a good hack! btw, i just compiled the latest voodoops2 kext from RehabMan (v1.8.24) and will push that out soon. Seems to get the trackPoint working better from a fresh boot. and apparently works better on the next rev of OSX.  So when the Sierra (10.12) public beta is available, i will test it out.

@goodguess - if the laptop has an nvidia/optimus card the external ports may be connected to the that unused gfx card vs intel HD3000 and yes 10.11.5 is straightforward upgrade. just download the combo update from the app store.

@R1kz - search this thread for gestures. the short answer is they are implemented in VoodooPS2Controller for 1,2,3 fingers with certain key mappings. The lenovo trackpad is not an apple (magic) trackpad so you can't have everything.

so if anyone is looking for a new LCD replacement for 1600x900, I am very happy with this part:  LG LP140WD2 (TL)(G1) for $43 on eBay- which is a glossy vs matte finish(TL)(D2). this LCD is very bright white vs (grayish) in comparison to the original LCD - even better than my 24" HP (sadly). my 8yr son cracked his LCD and i decided to give him my original LCD and keep the new one for me! - very big difference.

@tetonne - well it looks like the pmset tool is checking for invalid values now - and will only accept 0,3,25... but if you edit the plist file you can probably change it directly. in /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist here is what i use for my son's T420...$ plist-print.bash com.apple.PowerManagement.plistDict {   Custom Profile = Dict {   AC Power = Dict {   Hibernate Mode = 7   Wake On Clamshell Open = 1   System Sleep Timer = 60   Disk Sleep Timer = 10   TTYSPreventSleep = 1   Hibernate File = /var/vm/sleepimage   Display Sleep Timer = 30   }   Battery Power = Dict {   Hibernate Mode = 7   Wake On Clamshell Open = 1   System Sleep Timer = 10   Disk Sleep Timer = 10   TTYSPreventSleep = 1   Hibernate File = /var/vm/sleepimage   Display Sleep Timer = 5   }   }   LastSleepUU...

bluetoothmust be turned on by: 1) enabled in BIOS2) windows (leave on)3) then when you boot up OSX you will see the green light. and the OS will be happy. so to install windows. .. the cleanest method is to delete the 2nd OSX partition and replace with a window partition using gpt.the windows installer can do this (sort of) - last time i used the windows installer, it created a 2nd EFI a bunch of other partitions. here is script that will remove the last partition and replace with windows type of partition (unformatted) - so when you go into windows installer you can format this partition and install windows to it.#!/bin/bash# add 2nd windows partition - to keep PMBRif [[ $1 == "" ]]; thenecho usage: $0 diskexitfi# list partitionsmkfifo /tmp/mypipesudo gpt -r show $1 |grep "GPT part" >> /tmp/mypipe &n=0while read b s i gpt part dash tdon=$(( n+1 ))#echo loop $n $b $s $i $gpt $part $dash $tindex=$istart=$bsize=$sdone < /tmp/mypiperm /tmp/my...

@denva - glad to have another member to our forum! The issue is that current versions of OSX don't support VGA very well. So attaching a VGA monitor (analog) is passive vs digital (active). The best solution for you is get a DP cable to attach your monitor on a digital port. when DP is connected to the system will not sleep when you close the lid.

@dirtyMetis - i think there is a separate forum/thread for T430/530 that may point out any key differences. i looked at quite a while ago but do recall there was a lot in common. but yeah often the mixed gfx (switchable/optimus) can be challenge.

@superwkn - well it looks like the graphics artifacts that was plaguing me a few short weeks ago.- did you update your config.plist that sets CsrActiveConfig to 0x43- slide=0 boot arg- and use the standard graphics kexts - vs any rollback etc.- how much memory do you have - 8 GB seems ideal. also, you could try using OsxAptioFixDrv-64.efi (needs 0x43 setting) instead of the "Fix2Drv"

since there is manual control for TRIM (came in at 10.10.4 - so not that new :) ... maybe it is best to take the trim patch out the config.pist - which to my understanding is to disable the check for Apple SSD and turn on TRIM for any SSD

@tetonne - the clover config includes a TRIM patch so you probably won't need anything else. 

#2232277 Clover General discussion

@arsradi - one way to "purge" the MBR on GTP is the procedure i outlined (remove windows partition from GPT disk) will remove the MBR and replace with PBMR.  diskutil is geared towards bootcamp which likes to use MBR - dual boot UEFI with Clover is the way to go on a hack. so you need PBMR otherwise the windows installer finds a MBR and gets confused. gdisk - can do it as well -  convert the MBR to PMBR.

@rehabman - there is a way to get 7.3code to use older SDKs - so as before -in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs$ ls -l total 16 lrwxr-xr-x  1 root  wheel 40 Mar 21 21:20 MacOSX10.10.sdk -> /Applications/Xcode_SDKs/MacOSX10.10.sdk drwxr-xr-x  5 root  wheel  170 Oct 20  2020 MacOSX10.11.sdk lrwxr-xr-x  1 root  wheel 39 Mar 21 21:20 MacOSX10.9.sdk -> /Applications/Xcode_SDKs/MacOSX10.9.sdk but now edit the new key MinimumSDKVersion in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Info.plist $ diff Info.orig.plist Info.plist 87c87 <  <string>10.11</string> --- >  <string>10.9</string>
