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

    Love the app, but every time my computer reboots and loads the app it does not appear to have “Save states on exit” – my checked “disable lid sleep” is no longer checked. Anyone know how to get it to save states after a reboot? Thanks a lot.

    This app is fully manual. You save the settings. It saves them. I have for preferences “disable” for both AC and Batt for lid and idle. Guess what, if you unplug it, clears to enabled for all. You plug it in, only the idle re-enables but lid is disabled.

    So in other words its settings are not persistent. You basically have to get it all turned on each time you want it to work. MANUALLY managed. It’s a nice thought that they had, but in practice.. no worky.. I am on 2.0.1

    2.1.8 does not work. Is there a chance I can obtain .2.0.1?? I unfortunately deleted that version thinking this would be an improvement. 2.1.8 does NOT work at all… I went from bad to worse… :/

    Very usefull app! Definitely meet my needs!

    However, I have a question. What I want to do is to disable idle sleep but still allow display to turn off. If I turn on “Disable Idle Sleep”, the display is never turned off. How can I do this?

    I think you guys did a great job doing what apple didn’t. I appreciate anything, thank you. I’m bad with technology so i just click “Disable Lid Sleep,” shut my computer, the music keeps playing, the screen is out, and I’m a happy gal. 🙂 just hope it’s completely safe to download on my computer?

    hmm… my computer has been really hot (overheating) and i believe its from this download because it started to happen after i downloaded Insomniax.. sorry.. i do not recommend

    Insomnia 2.8.1 do not work well in MakOS Sierra – Freeze and affect the performance of other applications.

    It doesn’t seem to work properly on Sierra (10.12). Shortcut for display sleep has huge delay (screen is being turned off but if you move your mouse you will see your desktop instead of login screen). Also “disable lid sleep” doesn’t work all the time.

    What am I missing here? I’ve installed the latest version (2.1.8) on OS X 10.10.5. I want to disable lid sleep on battery AND AC. I have “Disable Lid Sleep” checked off”, and in Preferences I also have “Disable Lid Sleep on AC” checked off.

    So I close the lid while on battery, and my MBP stays awake as it should. Then, I go to plug it into AC and it immediately GOES TO SLEEP.

    Again, what am I missing here? (And, BTW, having the AC settings in Preferences while the battery settings are right up at the top of the main menu is kind of confusing as it is…just an opinion.)
