Cloaker for MAC
Free, open-source file encryption for Mac: drop a file on the window, set a password and choose where to save it. No installation needed.
Cloaker Overview
Cloaker 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.
Cloaker uses libsodium's file format, with XChaCha20-Poly1305 for the data and a key derived with Argon2id. Version 5.0 replaces the old Qt interface with a new one and libsodium with pure Rust code, while the file format stays the same: Cloaker 4 and 5 read each other's files, files from versions 1 to 3 still decrypt, and the web version at cloaker.mobi remains compatible. Cloaker also runs on Windows and Linux, and a separate command-line download for the Mac is available on the same page.
Cloaker is made by Theron Spiegl and is free and open source under the GPL-3.0 license. It is a universal app for Apple Silicon and Intel. The project does not state a minimum macOS version. Its release process has no Apple notarization step, so macOS may warn you when you first open the app.

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
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
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
