Preventing MacBook from sleeping when closing lid on Sierra Is there any way to prevent my MacBook Pro from sleeping when I close the lid on macOS Sierra? I used to use NoSleep on OS X El Capitan; unfortunately it stopped working properly after Yosemite and I've heard that on Sierra it causes problems, so I don't want to install it and potentially cause damage.

Does anyone use anything that they personally have used that prevents MacBooks from going to sleep when the lid is closed on macOS Sierra?
InsomniaX works perfectly on my MBP 13" 2015. I am using macOS Sierra 10.12. 

There's also an app called NoSleep, but it hasn't been updated in years, only use it if you're on older OSX like Mavericks or Yosemite.. I wouldn't recommend using it on Sierra..



UPDATE: 1st FEB, 2020
InsomniaX is not being mantained anymore &amp; you SHOULD NOT use it. No sleep is a better option until MacOS Mojave. Haven't tested any of these with MacOS Catalina. If anyone has tested with Catalina, let us know in the comments.
