InsomniaX for Mac disables lid and idle sleep on your laptop. When it’s functioning normally, your closed laptop works like a thin speaker. In all other cases though, it’s minimal in terms of features and poses an unnecessary risk to your device.
InsomniaX is a small utility that keeps your MacBook from sleeping even when you close the lid. The app only has one function and could be harmful to your computer.
You can download this program quickly and without any restrictions. Upon installation, you have to accept the user agreement. This document contains many warnings about the potential problems that InsomniaX can cause, which is discerning.
A small crescent moon icon will appear on your menu bar once you’ve launched InsomniaX. All you have to do to execute the function is to click the icon and select "Disabled Lid Sleep". This is useful if you want music to be playing without a display.
Sometimes the program freezes completely and panics your system. At this point, you’re forced to reboot. Since the app is set to “Load on Start” you can find yourself stuck in a frustrating loop. Unfortunately, if you have any trouble or questions, there’s no available support.
Where can you run this program?
You can run InsomniaX on devices with Mac OS X 10.7, 10.8, 10.9, and 10.10.
Is there a better alternative?
Yes, Amphetamine and Caffeine are two alternative keep-awake apps that effortlessly override your energy saver settings.
InsomniaX is a featureless app that, disappointingly, has the potential to panic your system. There are plenty of better alternatives that serve the same purpose safely and efficiently.
Should you download it?
No. Since the app makes system-level chances and only serves one purpose, it is not of much value for the average user. You should opt for the other two alternatives.
