Message: "We have detected incompatible security software installed on your computer. Please uninstall..."

To fix this problem, run a removal tool to remove the remnants of any third-party security software that was installed on your Mac.

Download and run the RemoveCompetitiveProducts tool

  1. Download the RemoveCompetitiveProducts tool.

    Unless you save it elsewhere, the file is downloaded into the Downloads folder.

  2. Click the Finder icon in the Dock to be in the Finder.

  3. On the menu bar, click Go > Downloads to go to the Downloads folder.

  4. In the Downloads folder, double-click the RemoveCompetitiveProducts.zip file to expand it.

    If you use Safari, the file is automatically extracted after you download it. Skip to line 5 to open the file in Terminal.

  5. In the Downloads folder, right-click or control-click the RemoveCompetitiveProducts.command file, and then click Open With > Terminal (default).

  6. If you see a prompt that the tool is from an unidentified developer, click Open to continue.

  7. In the Terminal window, type your administrator password to authenticate, and then press return. When you type your password, no characters appear.

    After the tool finishes removing the third-party security software and its remnants, it displays the message "Competitive Products of Norton removed successfully".

  8. Exit all the programs, and restart your Mac.

    After you restart your Mac, reinstall your Norton product.

Thank you!

Thank you for using Norton Support.
