Based on "catmater" post

My system configuration

  • CPU Core i5-6300u
  • Intel Graphics 530
  • SSD Intel M.2 512G
  • Touchpad + Trackpoint 

 

Work almost all: 

  • CPU scaling
  • Video with HDMI output 1920 x 1080
  • Sound speaker stereo
  • Headphones sound in jack
  • Mic (Siri also work)
  • Touchpad with some two fingers gesture + Trackpoint
  • Full level backlight
  • Wifi and bluetooth (wifi card replace with dw1560 - BCM94352Z)
  • Ethernet card
  • USB ports
  • Sleep

 

Not working

cardreader (no kext support yet)

NTFS-3G it makes OS hang and not response (no panic) need to power it off. (Use Mounty for R/W NTFS)

 

 

Don't forget after install or upgrade to Catalina 10.15 to copy files from Copy2LE folder to /L/E  and change permission / rebuild cache

 sudo cp -r Copy2LE/* /L*/E*/

 sudo chmod -Rf 755 /L*/E*

 sudo chown -Rf 0:0 /L*/E*

 sudo kextcache -i /

 

 

And of course don't forget completely turn off hibernate for a quick wakeup after lid open. 

sudo pmset hibernatemode 0

sudo rm -f /var/vm/sleepimage

sudo pmset hibernatefile /dev/null

 

My EFI Clover also has kext for Mojave supported. Just change the  kext/other-mojave to kext/other and using config-Mojave.plist
