Y50-70 UHD/4K(1080P) OpenCore5.8 10.15.4
BIOS settings
To start, set BIOS to Windows 8 defaults.
Then insure:
- UEFI boot is enabled
- secure boot is disabled
- enable Legacy Boot (but UEFI first) and you may experience less boot time glitches
For the UHD model, the DVMT-prealloc BIOS setting must be changed to 128MB. One of two methods can be used:
- use a EFI shell to change the DVMT-prealloc from the shell.
- use a patched BIOS which unlocks the advanced menu
Also, be aware that hibernation (suspend to disk or S4 sleep) is not supported on hackintosh.
- sudo pmset -a hibernatemode 0
- sudo rm /var/vm/sleepimage
- sudo mkdir /var/vm/sleepimage
