For users comfortable with the command line, macOS offers advanced options to manage sleep behavior through Terminal. This method provides deeper customization beyond the graphical interface.

One widely used command is `pmset`, which lets you configure power management settings:

bash
sudo pmset -a sleep

Replace `` with the desired time before the Mac goes to sleep. Setting this to 0 disables automatic sleep.

Some useful `pmset` options include:

  • `sleep`: Sets the system sleep timer.
  • `displaysleep`: Controls when the display turns off.
  • `womp`: Enables waking on network access.
  • `hibernatemode`: Defines the sleep state type (see table below).

Example command to prevent the Mac from sleeping:

bash
sudo pmset -a sleep 0

Hibernate Mode Description Typical Use
0 RAM powered on while sleeping; no image saved to disk Desktop Macs, fast wake-up
3 RAM powered; image saved to disk for safe sleep MacBooks for battery safety
25 System writes memory to disk and powers off RAM Deep hibernation, longest battery preservation

Remember to use `sudo` for administrative privileges and verify changes by running `pmset -g` to display current settings.

Customizing Sleep Mode with Third-Party Applications

If you require more granular control or automated profiles for sleep behavior, third-party utilities can enhance your MacBook’s power management capabilities. These apps often provide user-friendly interfaces and additional features, such as scheduling or context-based rules.

Popular applications include:

  • Amphetamine: Keeps your Mac awake based on user-defined triggers.
  • caffeinate (command line tool): Prevents sleep temporarily while a command runs.
  • Sleep Control Center: Offers detailed scheduling and custom sleep/wake actions.

These tools are particularly useful when performing long downloads, presentations, or other activities where you want to override default sleep settings without permanently changing system preferences.

Managing Sleep Mode for External Displays and Peripherals

Sleep behavior can also be influenced by connected hardware. When external displays or peripherals are attached, macOS may adjust sleep timing or prevent sleep altogether.

Key points to consider:
