To Prevent Mac from Sleeping , users can adjust system settings on MacBook through macOS by navigating to System Settings and modifying the “Lock Screen” and “Battery” or “Energy Saver” options. Setting display sleep timers to “Never” (or extending their duration) and enabling options like “Prevent automatic sleeping when the display is off” ensures uninterrupted workflows, especially during downloads, presentations, or remote tasks. Additionally, using trusted utilities such as Amphetamine can provide temporary control without altering core system preferences.
