Administrators Hervé Posted November 12, 2017 Administrators Share Posted November 12, 2017 I guess you can look into the thread about the 7480 with TB16 posted in this very section. 1 Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 20, 2017 Moderators Share Posted November 20, 2017 Systems with Broadwell / Skylake / Kabylake CPU such as Latitude E7450 and Inspiron 5548, you'll need to set the DVMT prealloc to 96MB in order to bypass KP and to enable full graphics with full QE/CI. For more info, see here. /!\ New Development: If you don't want to mod the BIOS as it might be difficult for some models, you could skip this step by adding 2 new kexts to /EFI/Clover/kexts/Other Lilu.kext & IntelGraphicsDVMTFixup.kext Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 21, 2017 Moderators Share Posted November 21, 2017 Copy kexts from /EFI/Clover/kexts/Other /LE to /Library/Extensions Repair permissions and rebuild cache sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / Reboot to Clover GUI, hit F4 on the keyboard, Continue booting to OS X . See if Audio is working. So both keyboard and trackpad are not working? Follow instructions from here to debug issue 1 Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 21, 2017 Moderators Share Posted November 21, 2017 remove these from /S/L/E, repair permission and rebuild cache AppleHPM.kext, AppleIntelLpssI2C.kext and AppleIntelLpssI2CController.kext Reboot. Download the attached, change permission and load the kext manually See if touchpad works. sudo chown -R root:wheel VoodooI2C.kext sudo kextload VoodooI2C.kext VoodooI2C.kext.zip 1 Link to comment Share on other sites More sharing options...
