If you’re interested in highly granular control of inbound and outbound connections, you can use Little Snitch’s Configuration app to create and refine rules. Rules editing lets you set very fine controls. That was a common use of Little Snitch, but it looks like most copies have switched to cloud-based licensed that requires a check-in to work. In the past, some software, like Microsoft Office, used local network probes to prevent multiple simultaneous copies running with the same license.

However, there may be software you don’t want to communicate in the foreground or background when it’s not in active use.

In practice, I rarely use these options, as I don’t want to grant access at all to something that I don’t trust for more than 15 minutes or during a session.

You can also select intervals from 15 minutes to 2 hours and Until Logout and Until Restart. While Forever is the default, holding down Shift toggles the menu choice to Once, and pressing Control toggles it to Until Quit. Little Snitch also lets you set timing for the rule, which lets you minimize access to apps or services you may not fully trust to have unfettered access. IDGĬlicking a hover-over ellipsis reveals a host of technical details.

This reveals highly technical details if you’re of that bent, like the IP address of the connection and whether the app or service involved has a code signature, meaning it’s been released by someone or some organization enrolled in Apple’s developer program. You can also hover near the eyeglasses, and click the … button that appears. You’ll have to allow sites and items referenced on sites one at a time as you visit, but that offers some people more piece of mind against unwanted Web-based trackers and even malware. You can be concerned enough about Internet safety that you changed prefab rules, like requiring individual approval of domain access in Safari, instead of letting it use all those ports. But even these passes are explicitly allowed via rules that you can view, with descriptions, in the Little Snitch Configuration app.

Many OS X system daemons, autonomous bits of low-level software, also get pre-approved. For example, Safari requests data from port 80 (non-secure Web connections) and port 443 (https connections) to pass through without notice. Little Snitch comes configured to allow common activities. (An IP address is a destination, like an apartment building a port is like a specific apartment within the building.) For instance, you can approve connections to all ports on a domain, or click on the allow/deny dialog to specify a port. Click a button here and there-like a downward-pointing arrow to the left of the Deny button-and you can expand options and limit choices. The default view offers simple details that shouldn’t frighten someone with no real technical knowledge as long as they get what a domain name represents and what apps are trying to do. The utility lets you drill down nearly everywhere. Clicking Allow or Deny adds a rule to Little Snitch’s configuration, bypassing this dialog in the future for varying degrees of specificity and periods of time. Using the previous example with a browser that’s not pre-approved, you might see an alert that Google Chrome is trying to connect to. This expanded network-connection popup shows information about the app and all the duration options for allowing or denying.įor previously unknown connections, Little Snitch presents a dialog box that shows you the requesting app’s icon, its name, and what it’s attempting to do.

Enabling it likely causes more problems and confusion for less-experienced users than leaving it off, but a Mac with unfettered bidirectional access isn’t a good thing, either. The firewall option in the Security & Privacy system preference pane is extremely coarse and lacks necessary features. It’s bizarre that this many decades into the net’s evolution, Apple still doesn’t include strong tools enabled by default that restrict access to your Mac or examine connections from macOS or apps you’re running out to the Internet. But the app has significant updates for visualizing connections and improves how it explains what apps are trying to do. Version 4 refines and extends this friendly firewall, and if you’ve used it or looked at it in the past, you’ll find it mostly familiar. The Internet is a terrifying place, and Objective Development’s Little Snitch 4 ($45) has tried for many years to help keep your Mac locked down by monitoring connections and letting you control inbound and outbound traffic.
