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

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:

  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.

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_.
