How to block an application from accessing the internet Mac
|
I'm looking for an application or way that can block applications from accessing the internet. I've heard of Little Snitch. But I was wondering if there are any free alternatives since that's that only thing I really want to do. thanks.
Do you want to just block access to the internet or stop a user using certain applications
I just want to stop an application from accessing the internet. I usually just do this on my pc firewall. but im not sure about doing it on mac.
I did try little snitch. but honestly i have no idea how to use it. and it asks me about every little thing and brings notifications about everything. All I want to do is block ONE application from accessing the internet. That's all.
The firewall in Leopard has an application mode. Seriously, though...if an application is misbehaving, just delete it. It's not worth fighting.
You can use sandbox-exec to block an application from accessing the net. First create a sandbox profile that blocks net access. This is just a file which will contain something like Code: If you look in /usr/share/sandbox there are some profiles you can look at if you want to figure out anything fancier. Then you run the application using sandbox-exec and passing in the profile you just created i.e Code: Where nonet.sb is the name of the file you created above and application-binary is the path to the executable you want to run (If the app is in an app bundle you'll have to hunt out the actual binary in the bundles MacOS directory).
Choose System Preferences from the Apple menu. Click Security. Click the Firewall tab. Choose the third mode: You can click the "+" button to add an application to this list. You can select an application and click the "-" button to remove it. Control-clicking on the application name gives you the
option to reveal the application's location in Finder. Once you've added an application to the list, you can choose whether to allow or deny incoming connections for that application. You can even add command line applications to this list. Shop for your Apple, Mac, iPhone and other computer products on Amazon.
