- 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)
