FireWally
FireWally is a macOS firewall app from Nektony that lets you monitor app network activity and control which apps can access the internet.
What is FireWally?
FireWally is a macOS firewall and network activity monitor designed to help users see which apps are connecting to the internet and control those connections. It is aimed at people who want clearer visibility into background traffic, tighter privacy control, or an easy way to stop selected apps from going online. The app shows real-time traffic activity, lets you allow or block internet access for individual apps, and offers hourly and daily usage views for tracking data consumption. It also includes protection modes for handling new app connections, including allowing them automatically, asking first, or blocking them by default. On supported Macs, FireWally can provide plain-language insights about why an app is connecting to the internet. FireWally is published by Nektony and runs on macOS 13.0 and later.

Safety overview
Status: Mostly safe
FireWally’s network filtering and connection-control features require a macOS Network Extension, which is consistent with a firewall app’s purpose. Because it can inspect and block app traffic, users should grant that permission only if they intend to use its firewall features and trust Nektony as the publisher. Blocking the wrong app can interrupt updates, syncing, sign-in flows, or other online functions. If you no longer want network filtering on your Mac, turn off FireWally’s extension in System Settings and remove the app.
Recommendation: Keep FireWally if you want per-app control over internet access or a simple way to watch background traffic on your Mac. If you do not use firewall or traffic-monitoring features, removing it should mainly affect its own filtering and monitoring functions rather than everyday macOS use.
