Earlier in September, Objective Development released Little Snitch 4.2 to add compatibility with macOS 10.14 Mojave and its Dark mode. The network traffic management utility also gained support for declaring certain types of connections as “private”—hiding the host and domain name information normally displayed in the Network Monitor and showing only a summary Private Connections entry. Plus, the update improved compatibility with NFS server processes, the performance of code signature checks, and the handling of localized Internet Access Policy of third-party apps.
Objective Development then issued Little Snitch 4.2.1 to fix a bug that caused an alert to be shown for an invalid code signature for the App Store in Mojave for some users. This latest update also resolves a bug with duplicating rules, improves Dark mode support, and brings back the capability to use the dark appearance of Little Snitch Network Monitor in 10.13 High Sierra and earlier.
