InsomniaX Logo

Version: 0.5/1.3.5/2.1.8

It always has been a missing feature: disabling the sleep mode on a Apple Laptop. Who does not want to use it as a big juke-box or go warwalking. The best looking server ever, especially at about one inch height. This small utility is what you will want, this small utility acts as a wrapper to the Insomnia kernel extension.




Note: InsomniaX is PASSIVE!
This means that unless another program has interfered with the operations of InsomniaX, once you reboot your system it will be completely removed from the system until you start InsomniaX and activate its features.

If after a reboot or during boot you exhibit issues, these are not related to InsomniaX. (The only exception is if you have InsomniaX in your startup items for your login)

Uninstalling/Repairing InsomniaX
The most common ticket in the help desk regarding issues with InsomniaX or requesting instructions on how to remove InsomniaX, below is a simple step list of what is required to completely wipe out InsomniaX. If any problems exist after removing InsomniaX it should not be related to Insomnia as it works as a passive changing, in other words once its unloaded all changes are moved (Especially after a reboot any trace should be gone)

  1. Reboot the machine
  2. Ensure InsomniaX is not running
  3. Enter in terminal : defaults delete com.semaja2.InsomniaX (use net.semaja2.insomniax for InsomniaX 2.1 +)
  4. Delete ~/Library/Application Support/InsomniaX (Use the terminal command “sudo rm -rf ~/Library/Application\ Support/InsomniaX”
  5. Delete /Applications/
  6. If reinstalling download latest version from MacUpdate

    Managed to get this to work with High Sierra. Reboot into recovery mode, open a terminal, and then do:

    spctl kext-consent add 4PUPLLX2PZ

    Thank you Bradley! Great little app for any MacBook!

    Great job getting this to work High Sierra, Malcom! ‘Reboot into recovery mode, open a terminal, and then do:

    Is there a way to start InsomniaX with “Disable Lid Sleep” and “Disable Idle Sleep” always clicked ?
    I need this because, for me “Disable Lid/Idle Sleep when on AC” under Preferences didn’t work, and I need it also on battery. (I’m on Yosemite)

    hi guys,
    I downloaded InsomniaX v.2.1.8 on my macbook Pro 8 GB running on OS X v.10.9.5 and although I am very happy with how this App works, I have been experiencing a very annoying issue since I installed the App:
    My Mac won’t go to sleep never again… even when InsomniaX is turned off and by closing the Lid the mac is supposed to normally go to sleep, it just keeps running awake. As you can immagine this is causing serious issues like a constant battery consumption… and I am now desperately looking for a fix

    would you have any recommendation to fix this?

    many thanks in advance,

    Thank you so much!

    It’s an amazing app!!
    As a developer myself, I understand how much time it can take to battle with intricacies of an OS, so thank you!

    I was pretty sceptical at first… but it works! I’ve only had it for a couple minutes but I’ve also tried it with bluetooth and its working great! Hopefully I don’t get a virus

    I’m using a Macbook Pro with a touchbar on macOS 10.14.2 Mojave. When I close the lid my touchbar disappears completely. I have to kill the app and restart it again.

    Does anyone experienced similar problems?

    Incredible. Love the timer function as well to auto re-enable sleep after a set time.

    Thank you!
