Not working yet.

I saw the bad reviews, but it was only $0.99 so i hoped it might work for me. No such luck.

This program simply doesn't work. All I wanted to do was be able to record in Ableton with my MacBook closed inside my backpack for portable recording, but no dice.

I guess I won't request a refund in hopes future updates will actually work. Until then, 0 stars.

Hi Jake,

Sorry you were not able to us ether app for the function you needed, Apple does not support the disabling of hibernating when the clam shell is closed, I requested this as a feature but it was denied.

It Works!

This app works as advertised! I was becoming more and more frustrated with not being able to hook up my Mac Book Pro that I recently bought (it's the 2018 version) and I researched how to activate clamshell mode on the device on the Internet, but nothing worked. I decided to give this app a try for 99 cents and thankfully, it works perfectly. Thanks, Shawn Hirst!

It works for me (no joke)

I accidentally bought it based on a review online vs in here and it worked, but i have an ultrawide 8k monitor (only 4k works with my cables) and its connected to a powered adapter for display port to mini display port... for some reason works... good luck.
