They are still being actively developed by Apple, so there is a significant amount of various issues associated with them. Unfortunately, as a replacement for Kernel Extensions, Network Extensions aren't around for long yet (they first appeared in this role in macOS 10.15). 'Kernel Extension' mode should be grayed out, and the 'Network Extension' mode should be selected. If you're already on Big Sur preview, make sure your AdGuard works in Network Extensions mode: open *AdGuard's menu -> Select Preferences. In macOS 11 (Big Sur), the old Kernel Extensions will not be supported (partly or at all), so we are adding support for the new framework. As an alternative, Apple offered System Extensions, and specifically Network Extensions as a framework for apps that filter traffic. The old framework - Kernel Extensions - was declared as deprecated.

System Extensions support in Big Sur įirst of all, what are System Extensions? It all started in 2019 when Apple decided to minimize the amount of code that's executed in kernel. Other than that, we made a lot of changes and enhancements to CoreLibs, which will result in an overall better filtering quality. Thanks to the adoption of System Extensions, AdGuard will work better on the newest macOS iteration - read below to find out the details. The biggest thing about AdGuard v2.5 for Mac is better compatibility with Big Sur.
