Modern Apple MacBook laptops featuring Apple Silicon processors are designed to automatically power on the moment you open the display lid or connect them to power. If you wish to disable this automatic startup feature, you can utilize the macOS Terminal application with a specific system management command. Open the Terminal app from your Applications folder or via Spotlight search, type the command "sudo nvram AutoBoot=%00" and press Enter, then input your administrator password when prompted. This command modifies the Non-Volatile RAM settings to prevent the Mac from booting up automatically upon lid opening. To re-enable the feature later, you can simply run the command "sudo nvram AutoBoot=%01" in the Terminal.

Modern Apple MacBooks manufactured with Apple Silicon (M1, M2, M3, and M4 chips) or recent Intel processors are designed by default to turn on automatically the instant you open the laptop lid or connect it to a power adapter. If you wish to disable this automated behavior, you must use the macOS Terminal utility. First, open the Terminal application from your Applications folder or via Spotlight search. Second, type the precise command sudo nvram AutoBoot=%00 and press Return. Third, enter your Mac administrator password when prompted (note that typed characters will remain hidden for security) and hit Return. This command modifies the NVRAM parameters to prevent auto-booting upon lid opening. You can verify success by shutting down your Mac completely, closing the lid, and opening it again without the machine powering on automatically.
