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
CloakerCloaker protects a file with a password in as few steps as possible. Drop a file onto the window, set a password and choose where to save the encrypted copy. To decrypt, drop the encrypted file on the window, enter the password and choose the output location. There is nothing to install on the Mac, because Cloaker comes as a single app bundle. Be careful with your password: if you lose or forget it, your data cannot be recovered, so keep it in a password manager or another secure backup.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
ExifCleanerExifCleaner removes hidden metadata from images, media files and PDFs, such as the GPS location, camera details and dates that photos often carry. Drag and drop files or whole folders onto the window and it cleans them in a fast batch, using ExifTool behind the scenes. You can expand any processed file to see exactly what was removed, before and after.Security
VeraCryptVeraCrypt is free disk encryption software. It creates an encrypted volume, a file that works like a separate disk once you mount it with your password, and it can also encrypt a whole partition or external drive. Everything you put inside is encrypted automatically, and without the password the data cannot be read. VeraCrypt supports hidden volumes for plausible deniability, several strong encryption algorithms, keyfiles and smart cards, and its volumes can be opened on Windows and Linux too.Security
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
CryptomatorCryptomator encrypts your files before they go to the cloud. You create a vault inside your iCloud Drive, Dropbox, Google Drive, OneDrive or any other synced folder, and everything you put in it is encrypted on your Mac. The cloud provider only ever sees scrambled files, while on your Mac the unlocked vault appears as a normal drive you can use from any app. Even file and folder names are encrypted. Cryptomator is made by Skymatic in Germany and has been independently audited.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- Little SnitchLittle 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.Security
KeePassXCKeePassXC is a free, open-source password manager for Mac, Windows and Linux. It stores your passwords, passkeys, notes and two-factor codes in an encrypted database file that stays on your own device, not on a company's server, and it opens with one master password, a key file, a hardware key or Touch ID. KeePassXC is made by the KeePassXC Team and released under the GPL license, with no subscription, no account and no paid version.Security
