InsomniaX: Disable Sleep On Idle Or Lid Close While On Battery Or AC [Mac]
MacBooks, like all other laptops, go to sleep when their lids are closed. The benefits of this simple function are multiple; you can close the lid and leave your MacBook with the assurance that it will be locked, and should you have forgotten to power it off, the power consumption will be minimized. That, nevertheless, doesn’t mean you always want the lid to trigger this function. Windows allows you to disable this function completely, but Mac, unfortunately, does not. InsomniaX is a free Mac app that not only lets you disable Mac’s idle sleep function, but also lets you stop your MacBook from entering sleep mode when you close the lid. The app lets you define these settings based on the power source, i.e., if the MacBook is running on battery, you may choose to allow it to enter sleep mode when the lid closes or the system is idle, and disable this behavior when it is plugged in.
