Solution

Steps to install:

IMPORTANT: Before you begin, open your Downloads folder and verify there is not an older version of the McAfee installer .dmg. If you find one, rename the file. Having an older copy in your Downloads folder could cause your Mac to mount the wrong installer and prevent your product from successfully activating.
  1. Open a web browser.
  2. Go to http://home.mcafee.com.
  3. Log in to your McAfee account.
  4. Under the product listing for McAfee Internet Security for Mac, click Download.
  5. Click I Agree to accept the End User License Agreement.
  6. If a serial number displays below the Download button, write it down. You will need it later to activate your product.

    NOTE: The serial number will be available for only two hours. If you want to install your product later, you can come back to this page to get a new one.
     
  7. Click Download.
  8. Click Save. The file is saved to your default location, usually your Downloads folder.
  9. Double-click the .dmg file you downloaded.
  10. Double-click the McAfee Internet Security for Mac installer file.
  11. Click Continue. The Welcome screen displays.
  12. Click Continue. The product features and system requirements display.
  13. Click Continue.
  14. Click Read License, read the terms of the license agreement, and then click Agree to continue the installation.
  15. Click Install. The Authentication screen displays.
  16. Enter your administrator user name and password, and then click OK.

    NOTE: Use the administrator username and password that you created when you first activated Mac OS X on your computer.
     
  17. Follow the on-screen instructions to activate your software. 
  18. Click Close to complete the installation. SiteAdvisor displays the following message:

    You need to restart your browsers to finish installing.

     
  19. Click Restart. Your browsers will close and reopen, and you might be prompted to enable the SiteAdvisor plugin.

    The following McAfee notification displays:


    We used the default Firewall settings to secure this network connection


    This notification originates from your firewall, indicating a new security policy has been applied. Your product is now installed and activated.


Steps to uninstall:
  1. Click Go from your Finder window.
  2. Select Applications.
  3. Double-click the McAfee Internet Security Uninstaller.
  4. Select the checkbox beside Uninstall SiteAdvisor.

Possible Installation Issues

Incompatible Applications  
In Mac OS X, Apple introduced an Incompatible Software folder during the OS upgrade process. When you install a product, known incompatible software is automatically moved into this folder to protect the stability of your system. Software that is incompatible with McAfee Security products must be removed from this folder before a McAfee product installation can complete.

For more information on the Incompatible Software folder, see http://support.apple.com/kb/HT3258.

For a list of incompatible third-party applications, see TS101083.



Conflicting Temp files
McAfee has found that some systems contain temporary files with restricted permissions that can conflict with the installation of Internet Security for Mac. When access is impeded, the installation may stop and present the following error:
A McAfee Enterprise version of the product is already install on your Mac. 

After confirming that the Enterprise version of the product is not installed, clear the Productconfig file in your temp folder (/private/var/tmp/) to resolve this issue:
  1. Select the Go menu option from Finder.
  2. Select the Go to folder menu item.
  3. Type the following path in the Go to folder window:

    /private/var/tmp/
     
  4. Delete the file Productconfig in the tmp folder location.
  5. Empty the Trash.
  6. Restart your computer.
  7. Begin a fresh install.


Possible Activation issue cause:

McAfee has determined that if a McAfee installation .DMG file already exists in the Downloads folder, the installer may mount the older version. The installer will then install that older version, which can no longer be activated without the Serial Number.

Workaround:
Rename any McAfee Installation .DMG files in the Downloads folder before downloading. This will ensure that only the latest version available gets installed. To rename the file, change the extension from .DMG to anything else, for example .DM_.
