Making specific hardware work with macOS requires understanding which components are supported and what patches may be needed.
Step 1 — Reset NVRAM and SMC
Use the OpenCore picker to reset NVRAM (hold Space at the picker).
Step 2 — Check Physical Connections
Verify that all internal cables are properly seated. Reseat RAM and storage if the system is unstable.
Step 3 — Verify Kext Coverage
Each hardware component needs a specific kext. For trackpads use VoodooI2C, for brightness use WhateverGreen.
Step 4 — Test Sleep and Wake
Disable Wake on LAN in BIOS and test sleep/wake reliability.
Expected Results
- Sleep and wake work reliably
- All peripherals are recognised by macOS
- System temperatures are reported correctly

Original Question: "BigSur - disable sleep?"
I’ve unchecked put hard drives to sleep where possible, but it keeps going to sleep.
I use plex media server so need it to be awake.
Is there a fix for this?
