Hackintosh Power Management for macOS Sonoma/Sequoia

• This guide provides step-by-step instructions for configuring power management, sleep mode, and hibernation on a Hackintosh running macOS Sonoma or Sequoia.
• It includes BIOS/UEFI settings, OpenCore configuration, and pmset commands to optimize your system's power behavior.
• Step-by-Step Instructions with Commands and Explanations.
• In my case Sleep works perfectly great in all modes without waking up.

# config.plist
HibernateMode to None in Misc -> Boot

1. BIOS/UEFI Settings
Recommended Settings:

• ErP Ready: Disable
• Wake on LAN: Disable
• Wake on USB: Disable
• HPET: Enable High Precision Event Timer
• ACPI S3: Enable Suspend to RAM (S3 sleep)

2. OpenCore Configuration: Add Required Kexts
Ensure the following kexts are in your EFI/OC/Kexts folder and added to config.plist:

• dortania.github.io/builds: Download
• NVMeFix.kext: Download
• USBWakeFixup.kext: Download
• HibernationFixup.kext: Download
• RTCMemoryFixup.kext (Optional): Download

3. OpenCore Configuration: Enable Necessary Quirks

☢️ (Optional)

# Use only if sleep or hibernation isn't working properly
# In most cases, it works without these parameters

#`DiscardHibernateMap`: Discards the hibernate memory map.
   Enable the DiscardHibernateMap (Optional): Booter -> Quirks -> true

# `DisableRtcChecksum`: Disables RTC checksum validation.
   Enable DisableRTCChecksum (Optional): Kernel -> Quirks -> DisableRTCChecksum -> true

# `EnableWriteUnprotector`: Allows writing to protected memory regions.
   Enable the EnableWriteUnprotector (Optional): Booter -> Quirks -> true

4. Check Current Power Settings and Assertions
Run the following command in the terminal:

pmset -g

pmset -g assertions

• Go to Energy Saver (for desktops) or Battery (for laptops).
• To open the pane, choose Apple menu > System Settings, then click Energy in the sidebar. (You may need to scroll down.)

Option	Description	Command (Don't use this cmd)
Low Power Mode	Reduce energy usage for computers that are always on (e.g., servers) and minimize fan noise.	sudo pmset -a lowpowermode 1
Prevent automatic sleeping when the display is off	Prevent your Mac from going to sleep automatically when its display is off.	sudo pmset -a sleep 0 (system never sleeps)
Wake for network access	Allow your Mac to wake from sleep to provide access to shared resources (e.g., printers, Music).	sudo pmset -a womp 1 (enable Wake on LAN)
Start up automatically after a power failure	Automatically start up your Mac after a power interruption.	sudo pmset -a autorestart 1
Enable Power Nap	Allow your Mac to check for email, calendar, and iCloud updates while sleeping.	sudo pmset -a powernap 1

5. Set Hibernate Mode
Configure hibernation mode based on your use case:

Mode	Behavior	Use Case
0	Disables hibernation. Uses Suspend to RAM (S3 sleep).	Systems with sleep issues.
3	Safe Sleep. Saves RAM to disk but keeps RAM powered.	Laptops, systems with battery backup.
25	Deep hibernation. Saves RAM to disk and powers off completely.	Desktops, servers, long-term storage.

Commands:

# Deep hibernation (recommended for desktops/servers)
sudo pmset -a hibernatemode 25

6. Configure Sleep and Display Sleep

# Both options work, my choice is `Options 1`

# Options 1. Prevent System Sleep While Keeping the Display Off
sudo pmset -a sleep 1                            # System sleeps after 1 minute of inactivity
sudo pmset -a disksleep 5                      # Disk sleeps after 10 minutes of inactivity
sudo pmset -a displaysleep 5                  # Display sleeps after 10 minutes of inactivity

# Options 2. Prevent System Sleep While Keeping the Display On
# sudo pmset -a sleep 0                           # Set the sleep timer to 0 (system never sleeps)
# sudo pmset -a disksleep 0                    # Prevent the disk from sleeping
# sudo pmset -a displaysleep 5                # Set the displaysleep timer to the desired time (e.g., 5 minutes)

7. Disable Unnecessary Wake Events

# Prevent the system from waking unexpectedly
sudo pmset -a womp 0                          # Disable wake on network access (Wake on LAN)
sudo pmset -a acwake 0                        # Disable wake on AC power
sudo pmset -a powernap 0                    # Disable Power Nap
sudo pmset -a proximitywake 0             # Disable wake on proximity (nearby devices)
sudo pmset -a tcpkeepalive 1                # Enable TCP Keep Alive during sleep mode
sudo pmset -a ttyskeepawake 1              # Keep system awake if remote session is active
sudo pmset -a networkoversleep 0              # Disable network access during sleep

8. Configure Auto Power-Off

# Set the auto power-off delay to save energy.
sudo pmset -a standby 1                       # Enable standby mode for all power sources
sudo pmset -a standbydelaylow 1               # Enter standby mode immediately (1 second)
sudo pmset -a standbydelayhigh 1              # Enter standby mode immediately (1 second)
sudo pmset -a autopoweroff 0                  # Disable automatic power-off
sudo pmset -a autopoweroffdelay 7200          # Set auto power-off delay to 2 hours (7200 seconds)
sudo pmset -a halfdim 1                       # Enable display dim before sleep
sudo pmset -a autorestart 0                   # Prevent the system from restarting automatically after a power outage

# Only for MacBooks and other Apple laptops
sudo pmset -a acwake 1                        # Laptops where you want the system to wake up when plugging in the charger.
sudo pmset -a lidwake 1                       # for MacBooks and other Apple laptops! This command controls whether your laptop wakes up when you open the lid
sudo pmset -a lowpowermode 1                  # For Mac laptops, use lowpowermode 1 to save battery or lowpowermode 0 for maximum performance.
sudo pmset -a highstandbythreshold 50         # Battery threshold for high-power standby.for both MacBooks and desktop Macs.

Check Current Power Button Behavior

• 1: The power button will put the system to sleep.
• 0: The power button will have no effect.
• 
  
• To open the pane, choose Apple menu > System Settings, then click Lock Screen
• Uncheck box Show the Sleep, Restart and Shutdown Buttons and You have to relogin
• 
  
• Before making changes, verify the current behavior of the power button:
• Press Windows + Alt and Press the power button briefly.
• Observe whether the system enters sleep mode or displays a shutdown dialog.

9. Debugging Sleep Issues

# Verify Current Sleep Settings
pmset -g
pmset -g assertions

# Check Wake Reason:
log show --style syslog | grep -i "Wake reason"

# Check Sleep Logs:
log show --last 1h | grep -i "sleep"

10. Final Notes

• Test your settings after making changes.
• Keep your kexts and OpenCore up to date.
• For Hackintoshes, ensure your ACPI/DSDT patches are correct
