AmphetamineĪmphetamine is a free keep-awake utility for MacBooks, which keeps them awake in clamshell mode even without external power. That way, you do not risk the chances of damaging your battery.

However, sadly, Apple lacks this ability. Linux and Windows laptops, on the other hand, intelligently detect the peripherals connected to a laptop and stay awake when the lid is closed. You see, all rechargeable batteries have a specific charge cycle - complete charge and discharge - and every time you charge it, it counts towards the battery’s degradation, which slowly wears it down to a point where it (sometimes) stops charging at all. However, only a very few actually realize the potential problems that it can inflict over time. Most users follow this (Apple) approach to use their machine with an external display. The default way or the Apple way of using your MacBook in clamshell mode - with external monitor and peripherals connected - is to have a power adapter always attached to the machine to serve power to the connected peripherals and prevent it from going into sleep mode.
