Uninstalling on OSX10.9.5

Recommended Posts

Hi, I inadvertently set up an incorrect product on my kids' iMac - have installed Cyber Security Pro instead of NOD32 ... since updating I now get the error message "Uninstaller cannot be opened because the identity of the developer cannot be confirmed".  I have also downloaded the installer for NOD32 & cannot install it either, & get the same error message.  The subscription I have paid for is for NOD32 but in some haste when I got this machine I wanted it protected so used a trial version of CSP, not having any idea this would turn into such an issue!  Any ideas appreciated, thanks ;)

Hello mrsgee,


Let's get this sorted for you.  :)


Please check your Gatekeeper settings by following these steps:

  1. Click on the apple logo on the top left of the screen
  2. Click 'System Preferences...'
  3. Click 'Security & Privacy'
  4. On the 'General Tab', make sure 'Allow apps downloaded from:' is set to 'Mac App Store and identified developers'.

If that is okay, please redownload the DMG file of Cyber Security Pro from the official ESET website:



Open the DMG file and double click on the uninstaller provided.

If it doesn't work and you're still getting the error message, right click on the uninstaller and click 'Open' from the menu that appears. You should then be able to click 'Open' similar to the error message.


After uninstalling, you must restart your Mac.


The other issue now is that NOD32 is not available for Home Users of Mac OS X, as ESET currently provides either Cyber Security (Essential protection on the Mac and Web, similar to NOD32), or Cyber Security Pro (including Firewall and Parental Controls, similar to Smart Security) to home users on Mac OS X.


Here's a link for more information about Cyber Security:
