英文简介：
For more than 20 years, Little Snitch has been keeping a watchful eye on your privacy, letting you know whenever an app wants to connect to the Internet. It has become the number one Network Monitor and Personal Application Firewall for the Mac. The Little Snitch Network Monitor shows you where your Mac connects to on the Internet. You decide what you want to allow or deny.
Connection Alert
Whenever an app wants to connect to the Internet, Little Snitch shows a connection alert, so you can allow or deny the connection. No data is transmitted without your consent.
Silent Mode
With Silent Mode, new connections are automatically allowed at first. So you won’t get interrupted and you can make your final decision later at your leisure.

Little Snitch encrypts your DNS requests and uses trusted DNS services such as Quad9 to keep your browsing private and secure. Requests are encrypted using DoH, DoT, or DoQ.

- All connections related to one app are now grouped under one entry in the connection list, including incoming connections and connections established via helper tools.

Creating and managing rules
- A new type of rules allows to show notifications in Notification Center whenever a certain kind of network activity occurs.
- Ability to create rules for “Any macOS Process” and “Any Simulator Process”.
- Local, editable rule groups, allowing you to organize rules by topic and enable or disable multiple related rules at once.

- Improved Homebrew support. Rules for Homebrew executables are now independent of the version number, which is part of the executable path.

Usage statistics for rules and blocklists
- See how often rules or blocklist entries have been used and when they were last used.
