Why block outgoing connections on Mac
People may wish to block outgoing connections for a variety of reasons, with the main one being privacy most of the times. If you’re reading this post, chances are you already tried to block outgoing connections on Mac. While OS X doesn’t have a feature that allows you to do so, blocking outgoing connections in OS X is easier than you may think.
Built-in incoming connections blocking
While you can prevent some applications, programs or services to accept incoming connections by configuring OS X built-in Firewall (Apple Menu => System Preferences => Firewall tab =>Firewall Options => Choose “Block incoming connections”, see the Figure below), to configure outgoing traffic preferences and block outgoing connections on Mac you need to download a third-party application.

Edit: when this tutorial was originally written, TCPBlock was still being updated. After OS X 10.11 (El Capitan), TCPBlock doesn’t work correctly on Mac anymore. If you are running OS X El Capitan or a more recent version of OS X like Sierra, then make sure you check out this updated tutorial. Users running OS X 10.09 (Yosemite) may also encounter some problems (even though it’s rare): in that case we recommend that you read the updated guide.
TCPBlock is a lightweight application that allows you to do exactly that, and you can download it from this link. Once you have gone through the download process, you just need to install it. In order to do this, open the package and follow the instructions. Then make sure you restart the machine you’re working with. You’re now ready to block you’re undesired outgoing connections.
Using TCPBlock is very easy, just follow these steps:
- First of all open the Apple Menu (Apple symbol on the upper left) and select System Preferences.
- Now click on the fresh new TCPBlock icon (it should be at the bottom of the window).
- If you see a closed lock at the bottom, just click on it and authenticate by prompting your password. If not, just skip this step.
- Finally, after you made sure you have the boxes checked as below, you just need to click on the + button, click on Select Application and add the application you wish to block the outgoing connections of.
- If you are having trouble finding an application, remember that you should find it under the “Application” tab you see on the left pane.
That’s it! You can now control all of the outgoing connections on your Mac. In addition you can even block all of the outgoing connections by checking the “Block all outgoing” box on the left if you wish to, just remember that this way you won’t be able to complete the majority of the tasks that require a connection to the internet.
Edit: unfortunately TCPBlock was discontinued. You can still download it, but it is now outdated. If you want to check out the updated tutorials we have on this topic, feel free to follow this link for a 2020 update, or this link for a tutorial focused on Little Snitch.

Most of the apps on Windows 10 are designed to connect to the internet when opened. When you click the app’s icon or shortcut, it automatically connects to the internet during launch to check for updates, provide improvements, or offer extra services. Whether you’re opening a browser or a simple Microsoft Word file, all of them have the capability to connect to your internet network.
Generally, you want your applications to have full internet access. However, there are times when you want to block a program from connecting to the internet for particular reasons. There are situations wherein you may wish to stay offline while using the app.
For example, if the application insists on updating itself, but you find those updates broken or causes functionality errors instead, then working offline will definitely stop them. If you have a child who likes to play video games, but you’re afraid of leaving him or her playing online unsupervised. Or if the program you are using keeps on flashing annoying ads and you want to silence them by cutting off the app’s internet access.
If the program works fine without being connected to the internet, you can simply choose to block apps from accessing the internet. Windows 10 is equipped with a functionality that allows users to prevent a program from connecting to the internet and keep it offline altogether. All you need to do is configure some settings on your computer to cut off internet access for specific programs.
How to Block a Program From Connecting to the Internet
Microsoft has simplified the process of preventing programs from connecting to the internet. You can do this via the Windows Firewall. Aside from protecting your computer against malware and other online security threats, you can also configure your Windows Firewall to block any app from accessing the internet. All you need to do is follow the steps below to exclude a program from internet access.

These steps work for other versions of Windows, such as Windows 7 and Windows 8, except for minor differences. This guide helps you to block both inbound and outbound traffic for a specific program on your Windows 10 computer. Inbound traffic refers to the incoming data to your app from a server outside your network, while outbound traffic refers to all outgoing data initiated by your app. When you block apps from accessing the internet, no data will come in or get out from the app that you are using.
Follow these steps if you want to block apps from accessing the internet:
How To Allow An App Through Firewall
- Press Windows + X to bring up the Power menu, then choose Control Panel from there. Alternatively, you can search for Control Panel using the Start search box and choose Control Panel from the list of search results.
- When the Control Panel window opens, click the dropdown beside View by, and choose Small icons. This should give you a detailed list of the settings under Control Panel.
- Click Windows Firewall from the list.
- In the Windows Firewall settings, click Advanced settings from the left menu.
- Click Outbound Rules from the left pane if you want to prevent the app from the sending outgoing traffic. If you want to prevent incoming data, choose Inbound Rules instead.
- On the right side of the window, click New Rule under the Actions panel.
- Click on Program and hit Next.
- Enter the path where your program is installed. The application path is usually in either of these forms:
- C:Program Filesapplication.exe
- C:Program Files(x86)application.exe
- The application is the name of the app you want to exclude from accessing the internet.
- Alternatively, you can locate the app with the Browse option if you don’t know the application path.
- Once you have the address, click the Next button.
- In the Action window, choose Block the connection, then press Next.
- Choose when the new rule will apply on the program. Tick off all three options if you want to completely cut off internet access.
- Name your new rule. For example, Block Google Chrome or Block Microsoft Word. You can use any name you want for this rule.
- Click the Finish button to complete the process and activate your new rule.
Once done, you should be able to see the new rule you just created under Outbound Rules or Inbound Rules.
When setting up your new rule, here are some things you need to watch out for to prevent errors:
- Make sure to clean up your computer first using Outbyte PC Repair for the new rule to work properly. Unwanted elements on your system can get in the way of your processes so it is necessary to delete them regularly.
- When using the Browse option to choose your .exe file, Windows uses the default environmental variables for that particular path. For example, you will see %USERPROFILE% instead of C:UsersAdam. This will break the Firewall rule and cause error. If the path generated by the Browse option does include an environmental variable, make sure to edit it and replace it with the correct and full file path.
- For most apps, blocking the main .exe file should prevent that app from connecting to the internet. But there are apps, mostly video games, where the main .exe file is not the one that connects to the internet. For most games, Minecraft for example, the Minecraft.exe is just the launcher and you need to block the Javaw.exe instead.
Block Application In Firewall
Once you’ve set up the rule, the next step is to test it out. Simply open the app you have just blocked to check if it is still connecting to the internet. If not, then congratulations! You’ve successfully configured your app to not access the internet.
