pmset

pmset is a command line tool used in macOS systems to manage power management settings. It allows users to control various aspects of power management, such as sleep settings, display behavior, and battery optimizations. The tool provides a variety of options and flags to modify power settings.

Users can view the current power management settings by running the command "pmset -g" in the Terminal. This will display information like battery status, sleep settings, and power source details.

pmset allows users to change sleep settings, such as the idle time before the system goes to sleep or the behavior when the lid is closed. These settings can be adjusted using command options like "pmset -b sleep X" (to modify battery sleep settings) or "pmset -c sleep X" (to modify AC power sleep settings).

The tool also enables users to customize display behavior, such as setting the display sleep time or enabling/disabling automatic brightness adjustment. This can be done using commands like "pmset displaysleep X" or "pmset -b lessbright X" (to modify battery brightness settings).

pmset can help optimize power usage for MacBook devices by adjusting various battery-related settings. For example, users can enable the "standby" mode that preserves battery life during extended sleep periods using the command "pmset -a standbydelaylow X".
