System Extension Blocked
A program tried to load new system extension(s) signed by "ESET, spol. s.r.o.", which will be incompatible with a future version of macOS. If you want to enable these extensions, open Security & Privacy System Preferences.
In macOS 10.16, kernel extensions in the current form will no longer be supported.
In ESET we are working on a solution that will be available before the release of macOS 10.16.
macOS High Sierra (10.13) and later contains a security feature that requires a user approval before loading new third-party kernel extensions.
