Sleep Control Center para Mac

Best app ever!!!! No other app would work like this one..so much headache after trying so many other apps that would not work..but this app works perfectly fine!! i just bought it!! He gave me some discount as well..if you send him a discount voucher!! I recommend this app for sure..This app is the best when you want to connect macpro to your computer, and have your lid closed when watching a movie!! Thank you Pavel

While there are a multitude of such menu items available with a significant number of them free, I have finally settled on 'Sleep Expert' as it is the only one I have found so far that has the ability to inform the user as to what Apps may be blocking Sleep. However I have also used both Caffeine and Amphetamine and found them to work as specified. Frankly I find this function to be a very crowded field of endeavor.

Seems to be working on MacOS Sierra? But my MacOS Sierra can't sleep properly. Any ideas? I'm using Flux, Jettison, Laploc.

I tried this program and Amphetamine and Caffiene. I like Anti Sleep best, especially for the new MacBooks with Haswell chips that no longer have a 'Never Sleep' option under Power Preferences. Here's what I like in Anti Sleep:
1) has a auto launch/auto activate on system startup option, great for remote systems, like a laptop, that need to be always on for access. No human needed to activate.
2) Has options to only activate when powered by AC, versus battery. Again, great for laptops

I provide remote assistance to family. When they need me to look at something on their system, I just need to tell them turn on the laptop, plug it in, leave the lid up. I can then log in anytime thereafter, even late night. I set options auto launch/activate at startup, activate only when AC is on, and stay awake indefinitely.
