Beware that Little Snitch and other similar network filter extensions leak your IP address to the remote server even if there's an explicit block for that server.<p><a href="https://lapcatsoftware.com/articles/2023/6/3.html" rel="nofollow">https://lapcatsoftware.com/articles/2023/6/3.html</a>
No longer using MacOSX, but this was definitely one of most useful and usable security tools ever created. Especially in a time, where more than half of all the anti-virus or firewalls you would get were just snake-oil.<p>I even got a nice bug bounty, because I discovered that a popular program pulled it's updates via HTTP and executed the downloaded executable directly thereafter.
I love the inclusion of DNS here, as that was a major pain point on version 5. Currently on MacOS you can only use a single network filter, which Little Snitch is, so you couldn't use an encrypted DNS service easily in addition to Little Snitch. This made it an instant purchase for me (and it works).
I seem to recall the past paid upgrades being timed to release with new macOS versions, but this one comes out ahead of WWDC in June, where presumably a new version will be unveiled. Is this related to the network filter extensions, so there's no longer the same risk of OS version incompatibilities?<p>An issue that's not unique to this developer, is that I'm having trouble determining what their update policy will be regarding the now previous version. Based on their past procedure, I'm not expecting it'll work with the next major macOS version, but it would be wonderful with clearer expectations on what types of bugs or security issues (if any) they commit themselves to fixing after the new version is out.
