You need Little Snitch 4.03 if you have a Mac computer running Mac OS X High Sierra. It’s here.
Right now, you can block with Little Snitch privacy invaders, malicious intruders, and other unwanted network activity.
High Sierra comes with a slew of new features, including a new file system, so some of your old applications might no longer work. One of the apps that won’t work is Little Snitch 4.
In the case of Little Snitch, you will need to acquire the new version, 4.03, which works with the released version of OS X High Sierra. You will also need a Little Snitch serial number that works with this version (serial numbers/license keys that worked with previous versions will not work with version 4.03).
As a matter of fact, Little Snitch versions as recent as 4.0 will not function with the released version of High Sierra. Also, if you have a Little Snitch 4 serial number, it will not work with version 4.03. So, when you install Little Snitch, you should expect problems unless you use version 4.03 or higher.
What is Little Snitch?
Your operating system and applications constantly work in the background to send and receive data through the internet. Although such continuity adds convenience to the user experience, it keeps you “out of the loop.”
In other words, unbeknownst to you, your computer could be compromising your privacy and security. Little Snitch solves this problem.
Little Snitch can alert you every time an application or system process tries to connect to the internet.
Similarly, the software will notify you of attempted incoming connections. As a result of having Little Snitch installed, you can decide whether to either permanently or temporarily allow or disallow network connections based on a variety of parameters.
Here, you will learn how to install and configure Little Snitch 4.03
Getting Little Snitch
You can buy Little Snitch from the application’s developer at www.obdev.at. You can also illegally download the application via torrent. If you choose the latter option, make sure that you use an anonymous VPN.
- Buy Torguard, the best VPN solution for torrent downloading.
- Sign up for Cactus VPN, another excellent solution for downloading torrents.
By using an anonymous VPN when you download applications via torrent, you protect yourself from the complications that can arise when your IP address is logged during the process of “illegal” activity. For example, your internet service provider can cancel your internet access.
Additionally, you may face legal culpability that can arise when the government or software developer takes enforcement action against you.
Installing Little Snitch
Installing Little Snitch involves a double-click on the installation .dmg file. The Little Snitch installer will guide you through a remarably simple installation process.
CAUTION: After completing the installation, the application will require you to restart your Mac.
When you regain access to your computer, you will see the Little Snitch icon in your computer’s Menu Bar. The icon displays network activity alongside the operating of Little Snitch (Alert Mode, Silent Mode (Allow Connections), and Silent Mode (Deny Connections).
By default, your Little Snitch installer sets the application to “Silent Mode (Allow Connections).” In essence, after your Mac restarts, your computer isn’t protected until you change the settings.
Clicking the Little Snitch icon in the Menu Bar will also give you access to Little Snitch configuration options and Little Snitch preferences.
Touring Little Snitch 4.03
Applications on your computer can send whatever information they want to wherever (and whoever) they want. For the most part, apps act for an honorable purpose and let you choose how they behave. Sometimes, however, they don’t.
When you have Little Snitch in “Alert Mode”, you will see a dialog every time an app wants to send or receive data over the internet. The alert will tell you what application or process wants to gain access and the destination or source with which that application wants to connect.
Little Snitch 4.03 alert boxes include the new “Research Assistant” that can give you more information about the proposed action. To get this information, just click on the eyeglasses icon located to the right of the alert.
The new Network Monitor will list attempted connections along with whether they were allowed or blocked.
Additionally, Network Monitor displays a traffic diagram that can help you analyze the traffic that passes into and out from your computer. Also, you will see a world map that will visually tell you the location of destination or original activity sources.
You can avoid the barrage of alerts that often comes with Little Snitch’s Alert Mode by placing the app in Silent Mode. This lets you focus on your work and then later create rules for handling your network traffic.
In the Little Snitch configuration window, you can add, delete and edit your connection rules.
Little Snitch has “Managed Rules” available that you can use to manage the standard operation of OS X High Sierra as well as iCloud. These options can save you time and aggravation as you configure Little Snitch.
I lost my Little Snitch Serial number, now what?
If you bought Little Snitch 4.03, contact the developer for support. You should be able to retrieve your Little Snitch serial number with their help (if you can’t do it on your own).
For emergency use, you can try the following Little Snitch serial number/license key: [THIS CONTENT HAS BEEN CENSORED. We are not allowed to display this Little Snitch serial number here.]
Keep in mind that the developer will disable your installation of Little Snitch and disable the above serial number unless you block Little Snitch authentication before you install the program.
How to Uninstall Little Snitch
Many people have contacted me because they don’t know how to uninstall Little Snitch from Mac OS X. As part of my commitment to add value to the community, here’s how to uninstall Little Snitch Network Monitor.
You can uninstall Little Snitch if you decide that it’s not useful to you. Unfortunately, running the Little Snitch installer no longer gives you the option to uninstall.
Instead, to uninstall Little Snitch on Mac, close your Little Snitch Configuration app. Next, drag the app to the trash can. You will need to enter the administrator password for your app.
Afterward, the Little Snitch uninstaller will automatically run. You will have a choice to delete all the data from your installation or just the app. If you plan on re-installing the program, you’ll probably want to save your configuration data, unless you want to start fresh.
After the Little Snitch uninstall, you will probably have to restart your Mac. Altogether, uninstalling Little Snitch is easier with this version than it ever was before.
In summary, Little Snitch 4.03 puts you in control of your computer and how it communicates over the internet. Using the app, you can disable undesirable internet connections, including attempts by apps to “phone home.” Also, the app includes tools that help you monitor historical behavior and learn about the sources and destination of the data used by your computer.
