Little Snitch is an amazing Network firewall Software which is very powerful and works well for the Mac & Windows operating system. This app monitors and prevent the applications and also allow them to connect to the network via advanced rules. Without a license key, Little Snitch runs in demo mode, which provides the same protection and functionality as the full version. The demo runs for three hours, and it can be restarted as often as you like. The Network Monitor expires after 30 days. Turn it into a full version by entering a license key.
Assuming you’ve downloaded the Little Snitch Disk Image (.dmg file) to your Downloads folder, open a new Terminal window and enter the following command to verify the cryptographic signature of the downloaded file:
codesign --verify -R='anchor apple generic and certificate leaf[subject.OU] = MLZF7K7B5R' ~/Downloads/LittleSnitch*.dmg
If the result of this command is empty (no error message is shown), the file is intact and properly signed by Objective Development.

However, if an error message is shown (like “not signed at all” or “failed to satisfy specified code requirement(s)”), this indicates that the file was maliciously modified and is no longer signed by Objective Development. In that case you should NOT open the disk image file.
