LG Gram 17Z90N Hackintosh

Opencore Version: 0.8.5

Work In Progress

• I have had this laptop since November, spent so many hours on this (so far I havent found anyone who has had success) and Finally got it to work YAY!
• I am excited to get this fully finished but still have more to do! Will update when I fix whats not working!

Instructions

1. BIOS Settings

2. Generate SMBIOS

• https://github.com/corpnewt/GenSMBIOS
• MacbookPro16,2
• Follow Guide to Add to config.plist - https://dortania.github.io/OpenCore-Install-Guide/config-laptop.plist/icelake.html#platforminfo

3. Boot Installer

• Boot Opencore, select installer, and Install Big Sur. (Youll have to Create a MacOS Big Sur installer)

Notes

• The NVME Drive that comes with this Laptop is a SKHynix 512GB which is not supported by Mac OS, Please replace it as it will not boot with it installed. (I bought a WD SN750 500GB that worked great).
• If the system Crashes, Kernal Panics, or you manually shut it down you will have to re-enter BIOS settings above. (Havent figured out how to save them even if it kernal panics)
• Fixed - Graphics glitches when booting then is completely fine after the first 10-20 or so seconds. (Fixed Thanks to 1OldSWguy)
