Legacy System Extensions on macOS 10.15.4 and higher

On 24 March 2020, Apple released version 10.15.4 of Catalina to macOS users. This update contains a check of kernel extensions on your Mac. If an application with kernel extensions is detected, macOS displays a notification about legacy system extensions. Click OK to close the notification. Your AVG product will continue to work as normal.

AVG AntiVirus and AVG Internet Security for Mac currently use kernel extensions to provide real-time protection for your Mac. We are aware that the Apple guidelines for software developers are changing and we are actively working to improve our products so that they are fully compliant with the upcoming changes. Our transition from kernel extensions to Endpoint Security and Network Extension frameworks is expected to be ready in time for the next major macOS release.

For more details about legacy system extensions, refer to the following announcement from Apple:

  • AVG AntiVirus 19.x for Mac
  • AVG Internet Security 19.x for Mac
  • Apple macOS 10.15.4 (Catalina) and higher
