Disable close lid? (InsomniaX alternative)

[Razer(x)]

I've used InsomniaX for years and it was awesome, I was able to close the lid and for example use an external monitor even without energy plugged

Is there any alternative working on High Sierra?

There is an app called Amphetamine that I believe does the same thing. There is a post here saying it works under High Sierra.

As far as I know Amphetamine cannot prevent the close lid sleep, just the normal one

That is my experience as well - I also need the InsomniaX functionality, i.e. no sleep when lid is closed, even without external monitor and keyboard attached. pls help

At the moment I got it working using "sudo pmset -a disablesleep 1" but it's not optimal

have you tried the terminal command caffeinate ? (see man caffeinate)

for example, (if you are running on a/c power) and type this into terminal

caffeinate -s

you can close the lid and it won't go to sleep. To stop it and allow sleep again just enter:

ctl-c

Add the & character to the end of the line and it will spawn a subprocess to run caffeinate which allows you to continue using the same terminal window for other stuff, although it's probably best to just use another tab for that so you can come back and stop caffeinate easier when required. The best thing is it's free and works on any version of macOS.
