Applicable for: Mac
You cannot install a Norton product on your Mac if you already have another security product installed on it. Uninstall the security product that is currently installed on the drive and then install your Norton product.
If the problem persists, run the RemoveCompetitiveProducts tool to uninstall other security software.
On the menu bar, click Go > Applications.
Do one of the following:
If an app isn't in a folder or doesn't have an Uninstaller, drag the app from the Applications folder to the Trash, then choose Finder > Empty Trash.
If the app is in a folder, open the app's folder to check for an Uninstaller. If you see Uninstall App or App Uninstaller, double-click it.
Follow the on-screen instructions to uninstall the app.
After completing the uninstall, restart your Mac and install your Norton product.
If the problem persists, go to step 2 to run the RemoveCompetitiveProducts tool.
Download the RemoveCompetitiveProducts tool.
Unless you save it elsewhere, the file is downloaded into the Downloads folder.
On the menu bar, click Go > Downloads to go to the Downloads folder.
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.
In the Downloads folder, right-click or control-click the RemoveCompetitiveProducts.command file, and then click Open With > Terminal (default).
If you see a prompt that the tool is from an unidentified developer, click Open to continue.
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".
Exit all programs, and restart your Mac.
After you restart your Mac, reinstall your Norton product.
