McAfee compatibility on macOS Mojave 10.14 and later

How has the installation procedure for new installs changed with newer versions of macOS?

  • Starting with macOS 10.13 (High Sierra) and extending to macOS 10.15 (Catalina), when an application tries to enable a system extension during installation, you are prompted to allow the system extension to be enabled. (A system extension is also known as a kernel extension or kext.) Until the system extension is authorized, some McAfee products for macOS will not provide you with complete protection.
  • Starting with macOS Catalina, you must grant our security products Full Disk Access for them to provide complete protection. Full Disk Access is a security feature in macOS Catalina that requires apps to be given permission before they can access all files on your Mac.

Until you enable kernels extensions and full disk access, you may receive the following errors:

First McAfee Alert error pop-up due to macOS permissions

Second McAfee Alert error pop-up due to macOS permissions

McAfee Alert error pop-up in McAfee general preferences due to macOS permissions
