I have tried to download No sleep many times but a message keeps popping up saying "No sleep kernel extension not downloaded". What do I do to get this app working?

Odds are that your pop-up says "No sleep kernel extension not LOADED." That's got something to do with SIP. You may have to disable it. Check the instructions.

If Nosleep won't startup, put Nosleep into logon (user/groups). This way it will startup.

I haven't looked at NoSleep in a while, so I just d/l'ed the latest version to see if its critical flaw has been fixed, and I"ve found that it hasn't, thus a one star review for an otherwise five star utility. NoSleep is the ONLY app/utility I"ve ever run across that allows you to set a pref and then unilaterally changes it with no warning, and in this instance, it could cost you your Mac. Try this: While operating your laptop on AC power, set your NoSleep pref pane for "Never Sleep on AC Adaptor;" now toggle your menu bar icon off, then on; now check your pref pane, and you'll find that along with "Never Sleep on AC Adaptor," "Never sleep on Battery" has been toggled on too. Congratulations! Your Mac is now ready to fry if you put it into your knapsack without realizing what you've done. Sorry, but no matter that the developer thinks that this is what people want, it is 100% TOTALLY INEXCUSABLE for an app/utility to unilaterally override a pref that has been set by a user with no notification.

Just a general suggestion that may help - check you System Preferences -> General, there might be a message about some "system extensions" being blocked. If so, verify that this is an extension from this application and click on Allow. This would install the extension this app requires to function

I really like NoSleep, but I am unable to figure out how to access it's preferences. The only functionality I have it to turn it on and off via the menu bar. It is not appearing in sys prefs, and I cannot get a drop down menu from the menu bar icon. Would someone let me know what I am missing.

Trashing just the NoSleep app won't remove its active components. The NoSleep download includes a separate script (named 'Uninstall.command') you can run to uninstall all of NoSleep's files. Double-click on the script, and it will open and run in Terminal.

The script lists the paths to NoSleep's components, if you want to manually drag them to the Trash instead:
/System/Library/Extensions/NoSleep.kext
/Library/PreferencePanes/NoSleep.prefPane
/Applications/Utilities/NoSleep.app
/Library/LaunchAgents/$KEXT_ID.plist

In addition, MacUpdate user 'Orubin' below comments that he found another item named 'Do Not Sleep.app' on his Mac's drive, but he wasn't sure at what path he found it, but he had to trash it to allow his Mac to sleep again.

I've been using NoSleep for the past six weeks or so, MacBookAir, Early 2015, with macOS Sierra 10.12.6. NoSleep is at 1.4 - and I've updated at least once since I've downloaded the app. I am a mobile user - I am often away with only my MacBook Air and when I come home I like to "dock" my MacBook Air with a KRADL Air mount - which closes the display lid my Air. I typically dock my Air as follows: - Close the MacBook Air without NoSleep running (the Air goes to sleep) - Plug in the MacBook Air - MacBook Air awakes, utilizes external display (via DisplayPort), USB Apple Keyboard and Magic Trackpad via Bluetooth - Start NoSleep and ensure it's enabled - Disable NoSleep by clicking on the ZZ's and uncheck Enable - Re-enable NoSleep by clicking on the ZZ's and check Enable After I do this it works pretty much everytime. I'm not sure why I have to disable then re-enable NoSleep after initiating it, but if I don't my MacBook Air goes to sleep. I have had one issue that caused me to hard reboot the Air - but it only happened once, not sure it was NoSleep's fault. I believe it's best for my battery to use it a few hours a day and when I'm docked I can run my machine unplugged. Thoughts?
