Whether you want to block outgoing connections on Mac for privacy, testing purposes, troubleshooting or other reasons, you are going to have a bad time if you try to do so on OS X. Nope, OS X does not allow you to block outgoing connections by default; you are going to need specific software in order to do so. Like it or not, your computer is constantly communicating with the rest of the world as long as you are connected to the internet, regardless of what you are doing. In this tutorial we explain how to block outgoing connections on Mac.

We previously wrote a similar tutorial in which we explained how to use TCPBlock. TCPBlock is an awesome software when it comes down to blocking outgoing connections on a Mac. Problem is, starting from OS X El Capitan (10.11), TCPBlock doesn’t work anymore. The same applies to any OS X version that came after that (note: even though TCPBlock is not officially compatible with OS X Yosemite, it actually works with no problems for us). So if you have OS X 10.09 or lower installed on your Mac (this includes OS X Mavericks and Mountain Lion), I recommend that you read this post. If you have OS X 10.10 (Yosemite) installed, you may want to try TCPBlock and see if it works correctly. In case you are running Yosemite but prefer to avoid TCPBlock, just keep reading. Finally, if your machine is running OS X El Capitan or Sierra (last version at the time of writing), then go on and find out how to block outgoing connections on your Mac.

Mac OS X Yosemite 10.10 is another product in Apple’s line of Mac OS X. Apple, in its line of amazing Mac OX titles, launched the Mac OS Yosemite 10.10 which took the world by storm. It’s new improved features allow even greater synchronization between iPhones and Macs when using the Internet. To make the removal procedure easier, Little Snitch has its own uninstaller that can be found using the following steps: Open Finder, search for Little Snitch DMG file. Click on Little Snitch Installer — yes, installer! A window pops up with two options: Uninstall and Install. Choose Uninstall to remove Little Snitch from Mac. Little Snitch is privacy/firewall software for the Mac from Objective Development Software GmbH that monitors network activity and gives you control and visibility for data leaving your computer via network connections. Features include connection alerts with flexible blocking of outgoing traffic, including on-the-fly control, rules-based configuration (with several aids) and configuration profiles (e.g. For different locations or networks); DNS name based traffic filtering; network.

Little Snitch and syncing (Mac) - posted in General Accordance Topics: I just tried to sync from Mac v. 11.0.3 to an iPhone via Accordance Sync with Mobile Device (i.e., both the Mac and the iPhone are on the same WiFi connection). As we know, Little Snitch is a host-based application firewall for macOS High Sierra. It can be used to monitor applications, preventing or permitting them to connect to attached networks through advanced rules. It is produced and maintained by the Austrian firm Objective Development Software GmbH. Are they looking for Similar for windows?

We selected four solutions for you, all of them are suitable for blocking outgoing connections. These are, namely:

1. Little Snitch (website)
2. Radio Silence (website)
3. Murus and Murus Lite (website)
4. IceFloor (website)

The developers of IceFloor also offer an alternative tool called PFList, if you want to check it out.

The following data is as of 01/05/2017.

In the rest of this post we will be focusing on Little Snitch since it is our first choice when it comes down to blocking outgoing connections on Mac. Radio Silence is pretty much like Little Snitch, with the advantage of costing as little as $9. A 24-hour trial of Radio Silence can be downloaded from this page if you wish to try it before completing the purchase. Murus comes both in a full version and in a lite, free version.

Little Snitch 3

Little Snitch is meant to give you control over your private outgoing data. If you want to block outgoing connections on a Mac, this is probably the best solution you can get, since it was created for this exact purpose.Sometimes you can even find coupons on Google and save a few dollars, even though this software is definitely worth the money. It is going to do what you need it to, and is going to do it well.

To start using Little Snitch, visit the order page of Objective Development and choose the most appropriate solution. After the checkout, you only need to download the software and install it. The installation process is really straightforward and you are guided through the steps. Once Little Snitch is installed, you will need to restart your computer.

After restarting your Mac, you can launch Little Snitch for the first time. A bunch of rules are automatically created for you: note that you should not change any of them unless you need to and know what you are doing. This is because most of them are required in order for your Mac to work correctly. By selecting a “locked” rule you can even check why it was locked and why it should not be changed.

Every time an application tries to communicate with the outside world through the internet, you will be prompted a dialog (Automatic Rule Creation). Once this dialog pops up, you have different possibilities: for example, you can allow or deny the connection forever, once or just for a while. Depending on the application and on your intentions, choose whatever you think is best. Allow the connection forever for every safe application that has no way to harm your privacy. Manage every other application as you think is best for you. As far as browsers are concerned, you should always allow their connection for them to work properly. The same also applies to peer-to-peer applications like uTorrent and related software.

You can manually create rules (for example if you can’t launch an application until a rule has been created) by selecting New Rule. This window even lets you choose the allowed communication ports and other technical details

It’s been four years since we explained how to block outgoing connections on a Mac using a third-party tool (TCPBlock), but Apple still hasn’t offered any built-in solution to deal with this task. While you can easily block all incoming connections using the built-in firewall, there is still no way to deal with outbound connections. While you can still download TCPBlock from this link, you should look for better alternatives since it hasn’t been updated in over five years.

Dmg for creating or modifying races. We also explained how to use Little Snitch 3 to block outgoing connections on a Mac, but here we want to present some better and up-to-date alternatives so that you can choose what is best for you.

Unfortunately, until Apple comes up with a solution, OS X users will have to continue using workarounds or dedicated third-party tools for this purpose.

Block outgoing connections on Mac

Several alternatives exist to block outgoing connections on OS X, and here we present a few so that you can choose the one you think best suits your needs.

The first solution makes use of the Mac Terminal to block outgoing connections, meaning it doesn’t require you to install any third-party tools. The downside is that it is a slightly less user-friendly solution.

The second solution is to let a program do the hard work for you. There are many tools available for download, either for free or for a one-time fee.

Let’s start by taking a look at the first option, how to block outgoing connections from the Terminal

Block outgoing connections using the Terminal

In order to block outgoing connections using a Terminal, you need to know the specific IP address associated to the service you want to block communication with. There are several ways to find your target IP address. One way is to monitor all open connections in OS X with the lsof -i Terminal command. If you are sure how to get this information don’t worry, you can just proceed to the next section that makes use of third-party tools to block specific outgoing connections. If you, however, happen to know the exact IP address you want to block, this solution might be the perfect fit for you.

Even though the process may not be familiar to you, especially if you’re not used to using the Terminal, it is a fairly straight forward procedure to follow. To configure your Mac to block a specific outgoing connection, proceed as follows:

1. Open the Terminal.
   There are multiple ways to do this: one way is to open your Applications folder, then click on Utilities and finally on Terminal. A faster way is to launch Spotlight by pressing Cmd + Space, type “Terminal” in the bar and double-click the search result.
2. Create a backup copy for the hosts file.
   Type (or copy and paste) the following in the Terminal you just opened:

   If you notice any strange behavior, remember you made a copy of your hosts file on your Desktop. I suggest you keep it there for a few days and, if you ever want to revert the changes you made, just edit the hosts file again to match the backup copy you have.

   Block outgoing connections using third-party tools

   If you don’t feel comfortable using the Terminal, don’t know the exact IP address you need to block, or just prefer the convenience of having a dedicated tool, this section is for you. Using a third-party tool may also be the best solution in cases where you need to block a lot of IP addresses and/or you frequently need to change them. Application firewalls are built just for this task.

   There are multiple tools to do this: Little Snitch, LuLu, NoobProof, TCPBlock, Hands Off, WaterRoof, and Radio Silence are some of them. TCPBlock is by far my favorite due to its simplicity and lightweight, but unfortunately it was discontinued years ago.

   For this post, I decided to stick with a paid and a free alternative: Little Snitch and LuLu.

   LuLu

   If you are looking for a free alternative to block outgoing connections on your Mac, LuLu is a great open source program whose source code is publicly available on GitHub.

   To install LuLu, you just need to navigate to their website and click Download. This will download a zip archive containing the application. Once downloaded, you can extract the archive’s content either by dragging the zip content inside a folder, or by right-clicking on the zip archive.

   Simply double-click on LuLu Installer and click Install to proceed with the installation. You will need to restart your mac upon completion. Upon reboot, proceed by configuring the program as you wish.

   LuLu will alert you anytime a new/unauthorized process attempts to create an outgoing connection. To block a specific application from accessing the internet, you can change that specific application’s rule by launching the LuLu application or by clicking on Rules in the status bar menu.

   

   And that’s it! Now you easily change any permission you want just by accessing the application at any time. For more complete instructions regarding your specific needs, or for troubleshooting, you can visit LuLu’s website which has some very nice tutorials.

   

   Little Snitch 4

   Although Little Snitch is not cheap, many people prefer it over alternative solutions. Before buying a license, you can download a free trial to see if the application has everything you are looking for. If you want to buy a license, you can do so at this link.

   To download Little Snitch, just click on Download and double click on the installer once it gets downloaded. The installation process is very straightforward and you just need to restart your Mac at the end of the installation process.

   You can now launch Little Snitch and you will be presented with some rules that it created for you. You shouldn’t need to change any of these rules as it may compromise your Mac’s behavior and cause malfunctioning.

   Just like with LuLu, you will be warned any time an application tried to communicate over the internet. At this point, you have different options: you can have the connection blocked or allowed, either temporarily, always or just once.

   You can also manually create a custom rule by selecting New Rule, which also allows you to only block specific ports.

   Done!
