Installation Guide

Post Installation Guide

(WIP)

Post install almost everything works,but audio via jack doesnt work, need to disable gfx to save power

  • Open Clover and put the following configurations
  • Use these kexts(All up to date as of Jul 31st 2018). You can get latest kexts if provided kexts are older
  • Fix Audio and input jack(the above kext files in conjuction with Clover conifg will takecare of this)
  • Disable 1050/ discrete graphics. https://www.tonymacx86.com/threads/guide-disabling-discrete-graphics-in-dual-gpu-laptops.163772/ . In my case i had to patch only one SSDT-8.aml file .In Clover config put SSDT-PNLF.aml file last in load order. You can check screenshot in Clover ACPI section.
  • Fix powermanagement-(already provided in clover config)
