Hello, these are my pc specs:



H97M-D3H Gigabyte

HD 4600 as a gpu

4gb DDR3

SSD 256gb


I attach my EFI folder, i removed only the mac serial.


I installed Catalina 10.15.6 with OpenCore 0.6.0, every things is working except for the wakeup.


I put the pc in stop form the apple icon, the monitors turns off, the pc turns "off".

When i push a keyboards button the pc turns on also the monitors turns on, but the screen is still black. Force rebooting is required. Any advice?


Thank you.
