@heavyhdx. Has to do with how safari decrypts and digitial rights info built into the lcd. We dont have it. You can edit the voodoops2trackpad info.plist and look for finger Z. Reduce to say 30 @avdo. Dock works. No dsdt change needed. I use the dp to my monitor. Dont think you need to change anything to add the usb3 card

Yeah. Safari cant decode it. Long story. But chrome is the way to go for html5 streams

@Tetonne - mine is the same for Displays in System Preferences. 2 tabs Display -  for Resolution and Brightness controlColor - to change the color profile - i use Lenovo LCD - which matches the /System/Library/Displays/Contents/Resource/DisplayVendorID-xxx to the injected EDID of the LCD

change the patch in config.plist to this - it will just patch the levels and not add VGA<dict>   <key>Comment</key>   <string>Patch Framebuffer Levels</string>   <key>Find</key>   <data>   AQIEABAHAAAQBwAABQMAAAIAAAAwAAAAAgUAAAAEAAAH   AAAAAwQAAAAEAAAJAAAABAYAAAAEAAAJAAAA   </data>   <key>Name</key>   <string>AppleIntelSNBGraphicsFB</string>   <key>Replace</key>   <data>   AQIEABITAAASEwAABQMAAAIAAAAwAAAAAgUAAAAEAAAH   AAAAAwQAAAAEAAAJAAAABAYAAAAEAAAJAAAA   </data> </dict>

appleALC is generalized HDA implementation and supports a wide variety of audio codecs (on Hackintosh). https://github.com/vit9696/AppleALCseems to work well for me. try it out. remove /Library/Extensions/AppleHDA_20672.kextand install these 2 kexts (in the attached zip) instead.  unzip the zip say in Downloadscd ~/Downloads/AppleALC_Lenovochown -R 0:0 *.kextchmod go-w *.kextsudo cp -a *.kext /Library/Extensionssudo mv /Library/Extensions/AppleHDA_20672.kext /Library/Extensions/AppleHDA_20672.kext.NUsudo kextcache -i / Attached Files  AppleALC_Lenovo.zip 567.87KB 12 downloads

@trifero - my longtime friend, I wasn't offended at all - or took it the wrong way at all.  it's all good. no problem here. you are welcome. sincerely welcome. questions for the forum:i have added the Lenovo T420 Conexant 20590/20672 to AppleALC.kextfor now I replaced usr-sse2's implementation for the Yoga as it was using ID 12 - which is very close to T420. anyway...is there interest to move that HDA kext solution instead of the AppleHDA_20762.kext?does anyone use the Dock audio profile? and then again, this may fall under the category: why fix it if it is not broken?!

well sure blame me! I strive to keep this zip up to date and working. sorry if it broke someones system. Recently, i moved to GitHub for the zip to keep a history of releases. so folks have options. why update? There are some changes in macOS that requires a newer Clover. but some then some changes in Clover after 4052 to simplifly things for the GFX config seems to backfire. but also note some of the recent posts have been for people changing to FHD screen. * which are out of scope for my standard guide* - The zip and guide support the T420 for standard LCD - 1366x768 or 1600x900. Anything beyond this laptop, is going to require some extra tweaking or retrofit.

@avdo - the current DSDT is compatible. you should be able to use the x220 disk or clone it (just change the ESP files - like DSDT). but an upgrade to sierra is not a bad idea either.

@somez - logs looks ok. the kext messages in Clover log is about the redundant set in ESP (for installers etc - not used if you install kexts in OS /L/E ) Thinning failed: EFI\CLOVER\kexts\Other\AppleHDA_20672.kextFailed to load extra kext (executable not found): EFI\CLOVER\kexts\Other\AppleBacklightInjector.kext so these 2 messages are ok/expectedHDA has symbolic link to binary (doesn't work from ESP)BacklightInjector is just property injector - no binary Extra kext: EFI\CLOVER\kexts\Other\IntelBacklight.kextwe don't need it anymore when AppleBacklightInjector.kext is presentmanually remove this one ---^

@jkdans- is your screen 1600x900? if so try this mount ESPcd /Volumes/ESP/EFI/Clover/ 1) edit config.plist - change Inject Intel true to Inject Intel false        <key>Inject</key>   <dict>   <key>Intel</key>   <false/>   </dict> 2) cd ACPIcp dsdt.edid.aml patched/dsdt.aml reboot

I think the code in IntelGraphicsDVMTFixup is sound.Problem is in Lilu...I will need more time to become familiar with the Lilu code. For now, I'd rather use KextsToPatch.  It is simple and reliable.@RehabMan - i really agree the frame buffer patch method is better than patch the assertion.Bravo to you for cracking the code for us lap-toppers with immutable bios!!! @sherlocks- i figured out why the DVMTFixup 1.1.3 was not working.- not a problem with Lilu- need change your patch count for each pattern Unlike, the old method which is a patch to avoid assertion, RehabMan's new buffer patches have more that 1 occurrence. so here is an example : changed number 1 to 7 matches for 01030303 00002002 00005001                     const uint8_t find2[]   = {0x01, 0x03, 0x03, 0x03, 0x00, 0x00, 0x20, 0x02, 0x00, 0x00, 0x50, 0x01};   const uint8_t replace2[] = {0x01, 0x03, 0x03, 0x03,...

@sherlocks - thanks for weighing in here. i was able to sort of re-create the black screen problem. Black screen happened when i turn off Inject Intel in Graphics section AND there is no EDID or DualLink set in the DSDT.  so if turn off clover gfx injection, and boot with a different DSDT with EDID and DualLink=1 then gfx works.
