McAfee Serial Numbers Not Working

I have attempted to install and uninstall McAfee multiple times on my MacBook and each time the serial number provided by McAfee does not work. I was transferred by AT&T to their McAfee department and the tech after an attempt to fix the issue was not able to and set up a call to take place on a Saturday 8/6 between 10 AM - 12 PM CST to work to resolve the issue, but I never received a call. AT&T should not offer a complimentary service without ensuring their vendor is able to ensure customers issues are resolved with their service. At this moment I still do not have the McAfee service that AT&T is marketing as a service, and I'm very dissatisfied with my service and experience thus far.

We apologize for the inconvenience with your McAfee service's serial numbers, dymartinez10.


If you haven't done so yet, please try reaching out the McAfee support team directly at 866-622-3911. Are you currently using AT&T Internet Security Suite? If so, we recommend that you switch to AT&T AntiVirus Plus. While it is also powered by McAfee, it's a better version of the Security Suite and easy to set up.


Here are the steps to install it:

  1. Go to AT&T AntiVirus Plus and select Download Now.
  2. Enter your user ID and password.
  3. If you have internet speeds of:
    • 3Mbps or higher, go to Step 4.
    • 1.5Mbps or lower, select Buy Subscription. You can purchase a subscription for $5 per month.
  4. Follow the prompts to download and install AntiVirus Plus.

Let us know if this information helped or if you need further assistance.
