Oops! NoSleep kernel extension is not loaded.
What steps will reproduce the problem?
Seen reproducibly - i.e. both after an update from 1.3.3 to 1.4.0 and after a
clean re-install of 1.4
What is the expected output? What do you see instead?
App seems to install normally (finder, launchpad, preferences) but cannot be
launched --> "Oops! NoSleep kernel extension is not loaded." error message :-(
What version of the product are you using? On what operating system?
OS X 10.8.5
Version 1.3.3 worked flawlessly
Version 1.4.0 shows the aforementioned problem

I have the same issue and I am also using OS X 10.8.5. I had to downgrade from
1.4.0 to 1.3.3 to get NoSleep working again.

Hi everyone. This issue is because kext signature verification mechanism is
different on OSX 10.8 and 10.9+. I don't have an access to system other then
10.10, so If you will be so kind, could you check this attached version before
it become available through autoupdate. Thanks! --Pavel

Hi am getting this since upgrading to 1.4 on 10.8.5
Original comment by [email protected] on 19 Feb 2015 at 9:22
Hello
I've gotten this same error message on 1.4, 1.33, 1.31, 1.1.
Using 10.6.8
Original comment by [email protected] on 19 Feb 2015 at 4:23
I have the same issue, I believe it was one of the recent security updates OS X
had that is causing this.
Original comment by [email protected] on 21 Mar 2015 at 4:58
Any idea when this can be fixed? I am still running 1.33. When will it be safe
to update?
Original comment by [email protected] on 25 Mar 2015 at 3:01
Update. I loaded 1.3.3 as that was the latest version available to download here: https://code.google.com/archive/p/macosx-nosleep-extension/ (Link via LifeHacker) Re-reading the above comments I searched and found a copy of 1.4 here: https://www.macupdate.com/app/mac/37991/nosleep
1.4.4 successfully installed.
Easy fix! Run the program (install the version above - https://www.macupdate.com/app/mac/37991/nosleep). Run the program (Applications > Utilities > NoSleep) and check on the status bar, next to WiFi / VPN / Bluetooth. You'll see 'Zz' Icon in bold text. click and hit enable and BOOM done!
MacOsHighSierra this would solve your issues.
sudo kextload -v /Library/StagedExtensions/System/Library/Extensions/NoSleep.kext
I was somehow missing the kernel extension, after reinstalling i found it under /Library/StagedExtensions/System/Library/Extensions/
Now it works.
for me it was a permissions issue:
$ sudo kextutil /System/Library/Extensions/NoSleep.kext/
Password:
Diagnostics for /System/Library/Extensions/NoSleep.kext:
Authentication Failures:
File owner/permissions are incorrect (must be root:wheel, nonwritable by group/other):
/System/Library/Extensions/NoSleep.kext
Contents

CodeResources
Info.plist
MacOS
NoSleep
sure enough it is not root:
$ ls -al | grep NoSleep
drwxr-xr-x@ 3 admin wheel 102 Apr 20 02:06 NoSleep.kext
update permission:
$ sudo chown -R root:wheel NoSleep.kext
and reattempt load of extension:
$ sudo kextutil /System/Library/Extensions/NoSleep.kext
thanks everyone for the kextutil commands above to help troubleshoot what was going on!
macOS Big Sur
Running this solved the issue:
sudo kextload -v /Library/StagedExtensions/Applications/NoSleep.app/Contents/Resources/NoSleep.kext
I'm facing the same issue in MacOS Monterey 12.3.1.
I've tried running sudo kextload -v /Library/StagedExtensions/Applications/NoSleep.app/Contents/Resources/NoSleep.kext and then allowing the kernel extension in System Preference, finally restarting my system, but it opens up with the same error.
macOS Big SurRunning this solved the issue:
sudo kextload -v /Library/StagedExtensions/Applications/NoSleep.app/Contents/Resources/NoSleep.kext
Solved for me in macOS Monterey. Thanks!
Hey there , after running this ::: sudo kextload -v /Library/StagedExtensions/Applications/NoSleep.app/Contents/Resources/NoSleep.kext
i have an this error ! Error Domain=KMErrorDomain Code=71 "Incompatible architecture: Binary is for x86_64, but needed arch arm64e" UserInfo={NSLocalizedDescription=Incompatible architecture: Binary is for x86_64, but needed arch arm64e}
sudo kextload -v /Library/StagedExtensions/Applications/Utilities/NoSleep.app/Contents/Resources/NoSleep.kext
sudo kextload -v /Library/StagedExtensions/Applications/Utilities/NoSleep.app/Contents/Resources/NoSleep.kext
This worked for me on macOS Big Sur 11.7.9 Thanks
On Ventura, I installed 1.5.2 and I still get kernel not loaded error.
When I try this command: sudo kextload -v /Library/StagedExtensions/Applications/Utilities/NoSleep.app/Contents/Resources/NoSleep.kext It says no such file is found but I know the file is there.
I copied the NoSleep.kext to another folder and run the same command with the new file path.
This time it says this: Error Domain=KMErrorDomain Code=27 "Extension with identifiers com.apple.nke.rvi,com.protech.NoSleep not approved to load. Please approve using System Preferences." UserInfo={NSLocalizedDescription=Extension with identifiers com.apple.nke.rvi,com.protech.NoSleep not approved to load. Please approve using System Preferences.}
I have no idea what this is. And in Ventura, the system preferences window is a whole new mess. I can't find anything related to NoSleep in it to be able to approve anything.
Please help me guys.
After many months, today I was able to make it work so I am sharing my solution here too. https://github.com/integralpro/nosleep/issues/54#issuecomment-2179454800
