@Timewalker - we look forward to seeing you on the T420 thread soon...

Notes:  (sorry about off-topic here)

 

BIOS: There is a modded bios for your new box to remove white-list and enable other adv features  - BUT STAY ON v1.46 !!! though.

USB3 - and there seems to be a report of using Rehabman's GenericXCHI kext for USB3 on el capitan for this Renaisas chop . as you know i have T420 (not T420s) - but others will be interested in your findings.

@vusun123 - well i am not familiar with this technique - can you share a link or details to provide more info?

 

history: most of the edits in the DSDT go back to almost 4 years ago - before clover etc - and not change much since Yosemite. The T420 model as you know is getting a bit "old", and any bios updates from Lenovo have not been very often in the last several years.  For example, I am using BIOS 1.46 from 2013 - since there is a modded version to defeat wifi whitelist. The latest BIOS 1.48 (2016) seems to be harder to mod - and folks are advised to stay on 1.46.

 

@peter7816 - cool about the W520...

 

are you leveraging the mods in the T420 DSDT? and kext set? the keys on brightness is 
1) the PNLF device in the DSDT - which is now very simple.

2) IntelBackLight.kext

 

not sure if the model would make a difference for you? generally the MBP8,1 model works well for this class of machine.

Brightness issue:

 

are you using ACPIBackLight.kext or the newer IntelBacklight.kext?

the newer IntelBackLight.kext doesn't require much in terms of DSDT additions ... my PNLF device looks like this now:

Device (PNLF)
                {
                    Name (_ADR, Zero)  // _ADR: Address
                    Name (_HID, EisaId ("APP0002"))  // _HID: Hardware ID
                    Name (_CID, "backlight")  // _CID: Compatible ID
                    Name (_UID, 0x0A)  // _UID: Unique ID
                    Name (_STA, 0x0B)  // _STA: Status
                    Name (XOPT, 0x06)
                }

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 Update

  • Updated to Clover r3566
  • Updated 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.
