How to fix sleep/wake issue on bigsur ?

Hello everyone,

I recently got my hackintosh up and running using opencore 0.6.3,

everything works except for waking up from sleep.

​

I've tried USB mapping using hackintool and export the kext to the kext folder under efi, oc clean snapshot the config list, now the USB ports work so does the fenvi t919.

However, when I press sleep or lock (lock button first takes me to the lock screen then sleep after 3 seconds), my pc goes to sleep with "No connection" showing on my monitor, when I move my mouse or press a key on the keyboard, my Apple Watch gives me "Unlocked mac by this apple watch" but monitor still showing "No connection".

Can anyone advise me on how to fix this?

​

My specs:

i5-6500 using iGPU

GA-B150-HD3

Fenvi T919

​

Thanks in advance!
