Mcafee Big Sur



  1. Note: The incompatible versions of McAfee Active Response, Threat Prevention, Adaptive Threat Protection, and MVISION EDR detected during the upgrade will not be started. To restore functionality, deploy a compatible version of these products that supports Big Sur. For information about compatible Big Sur versions, see McAfee Knowledge Base article KB90888.
  2. Mac users:If you have upgraded to Big Sur (macOS 11); For McAfee version 4.9.x users,a popup message from McAfee is displayed, perform a manual update as listed under Step 2 in the article TS103036. If the manual update failed, please contact support.
  3. Apple created two paths on their Software Development Kit (SDK). One for current and future products, and another for backwards compatibility. When it queries the Mac operating system, MA incorrectly returns the macOS as version 10.16. Conflicts in reporting through ePO queries and reports causes confusion on what Mac operating system is installed on the client.

I had McAfee installed on my Mac Mini (late 2014) I updated the OS to Big Sur and the McAfee software did not work. I called McAfee and was on the phone with them for over an hour trying to reinstall their software. They could not get it to work and suggested I contact Apple support. If I can't get my Mac Mini to take the reinstallation is it true that the Apple software has it's own virus protection built in or should I try reinstalling somehow the previous version I had on my Mac?

Jan 08, 2021 Apple released macOS 11 (Big Sur) on 12 November 2020. When you upgrade your existing macOS to macOS 11 (Big Sur), and you have an older version of McAfee security software installed, you might see the following message when you log on to your Mac: Allow us to continue your setup.
