Hi, new to the board and was looking for some info to get started with the dell latitude 7280.

 

 

Intel Core 7th Generation i7-7600U Processor (Dual Core, up to 3.90 GHz, 4M Cache, 15W

Intel® HD Graphics 620

audio: Realtek ALC 3246

swapping out the wlan card with:  XPS 15 9550 WLAN DW1830

Is sierra or high sierra easier install?

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

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?

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
