If you’re a MacBook owner there are probably times you’ve wanted to close the Mac’s lid without invoking sleep. As it turns out, there’s an app for that. It’s called, conveniently, NoSleep.
Here’s how it works.
All MacBooks go into sleep mode when the lid is closed. NoSleep keeps the Mac running. And the Mac stays warm. The options are simple. Set NoSleep to startup when your Mac is turned on. Click the Do Not Fall Asleep When Lid Is Closed option, and the Mac stays awake when the lid is closed.
Won’t a closed-lid Mac cause overheating? It could. There’s a reason the MacBook’s operate with the lid open, so overheating is a definite possibility when the lid is closed. For now, NoSleep is free.
