Cannot Install Pixel Map Software for ETCnomad Mac


When trying to install the pixel map download, you encounter an error screen that says the file cannot be opened because it is from an unidentified developer.


This means that your Mac computer does not recognize ETC as a developer and you need to allow permission to install from the developer anyway this time.


  1. When you receive the error window, click on Okay
  2. Navigate to your Mac System Preferences -> Security and Privacy  -> General
  3. You should see a box prompting you to allow to install from ETC anyway, click on that to accept
  4. Go back to EOS Family Welcome -> Settings -> General -> Software update and re-run the installer
