Little Snitch for MAC
See where your Mac connects to on the internet and allow or deny each connection. Paid app with a free demo mode.
Little Snitch Overview
Little Snitch shows you where your Mac connects to on the internet and lets you decide what is allowed. Whenever an app wants to connect, a connection alert asks you to allow or deny it, so no data leaves your Mac without your consent. Its Network Monitor shows all connections in real time, on a world map and in a traffic chart, grouped by app, domain or country. Little Snitch is made by Objective Development and has been protecting Macs for more than 20 years.
Little Snitch is a paid app. Without a license key it runs in demo mode, with the same protection and features as the full version; the demo runs for three hours at a time and can be restarted as often as you like, and the Network Monitor works for 30 days. Little Snitch 6.5 runs on macOS 27 Golden Gate and is also compatible with Tahoe, Sequoia and Sonoma. Update to 6.5 before you upgrade to macOS 27.

ClearanceKitClearanceKit is a free, open-source tool that controls which programs on your Mac may touch your sensitive files. It uses Apple's Endpoint Security framework to watch file-system events such as opens, renames, deletions, copies and directory reads, and blocks any process that accesses a protected path without an explicit allow rule. It is aimed at developer machines, where an unsandboxed npm, pip or brew install script runs with your full permissions and could otherwise read folders such as ~/.ssh, cloud credentials or browser cookies.Security
MakLockMakLock is a lightweight menu bar app that protects your macOS applications with Touch ID, Apple Watch proximity or a backup password. When someone tries to open or switch to a protected app, MakLock blocks access with a full-screen blur overlay on all your monitors and asks for authentication. It watches for app switches as well as launches, so returning to an app that is already running also needs unlocking.Security
KnockKnockKnockKnock is a free, open-source Mac security tool that shows what is persistently installed on your computer. Malware usually installs itself so that it runs again each time the Mac restarts, and KnockKnock uncovers software that has done this, whatever its name. Press Start Scan and it goes through the known places where such software can hide, then lists what it found by category, with the number of items in each.Security

Drag and drop files or whole folders onto the window and it cleans them in a fast batch, using ExifTool behind the scenes.

Pareto SecurityPareto Security helps you keep up basic security on your Mac. It lives in the menu bar and regularly checks common settings that are easy to forget: whether FileVault disk encryption is on, the firewall is enabled, automatic login is off, Gatekeeper is active, the screen locks automatically and your apps are kept up to date. When something is off, it gently reminds you to fix it. The idea behind the name is the Pareto principle: take care of the 20% of security tasks that prevent 80% of problems.Security
LuLuLuLu is a free, open-source firewall for Mac. Almost every app connects to the internet, and so does malware; LuLu watches outgoing network connections and asks you whenever a program it doesn't know tries to connect, so you can allow it or block it. Your decisions become rules, and LuLu applies them from then on. LuLu is made by Objective-See, a non-profit foundation for Mac security tools, and is released under the GPL-3.0 license.Security
