Little Snitch overview
Little Snitch gives you control over your private outgoing data.
Track background activity
As soon as your computer connects to the Internet, applications often have permission to send any information wherever they need to. Little Snitch takes note of this activity and allows you to decide for yourself what happens with this data.
Control your network
Choose to allow or deny connections, or define a rule how to handle similar, future connection attempts. Little Snitch runs inconspicuously in the background and it can even detect network-related activity of viruses, trojans, and other malware.
What's new in version 6.5
Important: Upgrade to this version before you upgrade to macOS 27 Golden Gate! Previous versions of Little Snitch are not compatible with macOS 27 Golden Gate and would break your internet connection after the macOS upgrade.
Improvements:
- Compatibility with macOS 27 Golden Gate.
- App bundle integrity monitoring. Little Snitch now monitors the integrity of its app bundle not only at app start (like before) but also while the app is running, presenting a warning dialog if an unexpected modification of its app components was detected.
- Clicking an already selected location in the map (which filters the connection list to show only connections to that country/region/city) now clears that selection to reset the location filter.
- Using the term “traffic volume” instead of “traffic amount”.
- Improved appearance of search fields in inactive windows.
- Added an experimental implementation of NAT64 (RFC 6052).
Bug Fixes:
- Fixed an issue that prevented expired temporary rules from appearing under Suggestions > Expired.
- Fixed a rare crash that could occur when searching for a process by exact match with an empty search string in the rules list.
- Little Snitch no longer uses hostnames for inbound connections.
- Improved and fixed various aspects of encrypted DNS.
- When a socket is closed for outbound traffic only, incoming bytes are now still accepted.
- Various other bug fixes and improvements under the hood.

Version: 6.5
v6.5 is out. Compatible with macOS 27 Golden Gate, still Universal app. I've been using the nightly builds for past several months with macOS 27 betas, and have had no issues. I suspect in the next six months many vendors will deprecate Universal builds in favor of separate Intel and ARM builds (reduce file size and maintenance). Apps that will require 27 or later will just be ARM.

Version: 6.2.2
I've been using Little Snitch for years, now version 5.8. I considered upgrading to version 6 but the list of new features make it seem like Little Snitch has become bloat-ware. Even in version 5, I only use a small part of its total features. All I care about is blocking incoming and outgoing traffic to questionable sites. I couldn't care less about hierarchies, interactive traffic chart, smarter searches, blocklists, acoustic notifications, rule groups or usage statistics. I'm not a Little Snitch hobbyist. I think the author should offer a version 6 Lite without all the crapola at a reduced price to serve the rest of us.

Version: 6.2.1
Out of the blue, after a restart I found v6.2.1 was blocking the ability of my Mac (MBA M1 running 15.3.1) from interacting with the Internet, no matter what app or service. This problem was *specific* to running Little Snitch. Everything else is working. Uninstalling it unclogged the problem. See the dev website for full uninstall instructions. It's not easy. - -> I'll be reinstalling it later, hoping it won't reenact the problem. I'll be contacting the developer. 😠
