Here are the most likely explanations and resolutions for the issue:
- Please check that your version of macOS is compatible with the latest version of NXPowerLite. For example, NXPowerLite Desktop v10 is only compatible with macOS 11.0 (Big Sur) and above.

If your version of macOS is compatible with NXPowerLite Desktop then continue troubleshooting below
- By default macOS allows you to open apps from the official App Store only. Try changing the setting for Allow apps downloaded from to App Store and identified developers. This can be found if you go into System Preferences > Security & Privacy. Now retry the NXPowerLite DMG file.
- If that does not work, open the app in System Preferences and override the block.
Open System Preferences and go to Security & Privacy, and make sure the General tab is selected. (You'll see that this is the same page where you tell macOS to allow apps from identified developers as well as from the App Store.)
If you've been blocked from opening an app within the past hour, this page will give you the option to override this by clicking the temporary button 'Open Anyway'. You'll be asked one more time if you're sure, but clicking Open will run the app.
- Corrupt Download: The downloaded dmg file is actually corrupt or had an error downloading. If possible, try downloading the dmg again, and turning off any download assistant plug-ins you may have. You can also try downloading the file in a different browser.
Alternatively, try curl -O URL in Terminal to download the file. The download commands for the last three versions of NXPowerLite Desktop (mac) are below:
curl -O https://cdn.neuxpower.com/releases/desktop-mac/9.1.2/NXPowerLiteDesktop91_2.dmgv8
curl -O https://cdn.neuxpower.com/releases/desktop-mac/8.0.8/NXPowerLiteDesktop80_8.dmg
The above command contains the letter O rather than the number zero.
- Rename the DMG file and ensure the downloaded DMG file is stored in a local drive e.g your Desktop. These two actions can remove any permissions issues although do check security policies for the file to ensure the correct permissions.
- Reboot your Mac if you haven't already tried that. Sometimes there are issues after opening too many dmg files, that is fixed with a reboot.
- Try mounting the DMG on the command line in Terminal. We will at least get some sort of useful error message to go on if it still fails:
- Open Terminal
- Type hdiutil attach into the terminal. Don't press enter yet.
- Drag the dmg file from your Finder window onto the Terminal window and let go. This will fill in the location of the dmg file into your Terminal window.
- Press enter.
- If all of the above fails, please contact us for an alternative link to your specific version of NXPowerLite.
