melamangiata Posted August 17, 2020 Share Posted August 17, 2020 Hello, these are my pc specs: i5-4460 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.
