Quick Answer
The best encryption software for Mac depends on what you are protecting. For full disk encryption, Mac's built-in FileVault is the standard. For encrypting specific files, folders, or USB drives to share or store in the cloud, a dedicated AES-256 third-party tool like Folder Lock is recommended, as FileVault leaves individual files unencrypted once your Mac is logged in.
What People Search For: Resolving Your Encryption Needs
Finding the right tool means understanding your exact scenario. We analyzed search intent to categorize the most common Mac encryption problems. Select your goal below to jump to the right solution.
How to Encrypt Files on Mac Without FileVault
If you need to encrypt a single folder rather than your whole drive, macOS Disk Utility allows you to create an encrypted DMG image. Alternatively, third-party file encryption software provides "on-the-fly" locking without the hassle of mounting and unmounting virtual drives.
FileVault provides full disk encryption (FDE), protecting data at rest when the computer is off. However, once you log in, all files are decrypted and accessible to any app or person using the machine. Third-party tools protect data in use, keeping specific folders locked even while the Mac is awake.
Does encryption slow down your Mac significantly? Modern Macs use Apple Silicon (M1/M2/M3/M4) which includes hardware-accelerated cryptography. FileVault has a near-zero performance hit. However, encrypting large video files on older Intel Macs or slow external hard drives can cause bottlenecks.
If you forget an encryption password, recovery depends on the tool. FileVault can sometimes be unlocked using an iCloud account or a generated Recovery Key. Commercial tools often rely on master passwords that cannot be bypassed by design.
macOS comes with powerful built-in security features, but they do not cover every scenario. Here is a breakdown of your options, from native tools to the best free encryption software for Mac.
1. Apple FileVault (Full Disk Encryption)
Difficulty:
Setup time: 2 mins
FileVault is Apple's native full-disk encryption program for macOS. When enabled, it encrypts the entire startup volume using XTS-AES-128 encryption with a 256-bit key. It is the best defense against physical theft.
Best for: Protecting your entire Mac if it is lost or stolen.
Limitations: It does not protect individual files from network attacks, malware, or unauthorized users once the computer is unlocked.
2. macOS Disk Utility (Encrypted Folders)
Difficulty:
Setup time: 5-10 mins
Disk Utility allows you to create a password-protected DMG (disk image) file. You put your sensitive files inside, and unmount it to lock them. macOS supports 128-bit or 256-bit AES for this.
Best for: Storing old tax returns or static archives you rarely access.
Limitations: Clunky for daily use. You must specify the maximum size of the vault when creating it, and mounting/unmounting is a manual process.
3. VeraCrypt for Mac (Open Source)
Difficulty:
Setup time: 20+ mins
VeraCrypt is a highly secure, free, open-source encryption tool. It succeeds TrueCrypt and allows you to create hidden volumes (plausible deniability).
Best for: Advanced users requiring extreme security or cross-platform (Mac/Windows/Linux) compatibility.
Limitations: Requires installing MacFUSE (a third-party file system extension) which can conflict with newer macOS versions (Ventura, Sonoma, Sequoia) due to strict System Integrity Protection (SIP) rules.
"While macOS native tools are great for device loss, they fail to protect files when the system is actively running. For sensitive business data, you need file-level encryption."

The Tool We Recommend for Most Users
Of all the options we tested, built-in Mac tools are often too rigid for daily use, while open-source tools require complex kernel extensions. For securing files on the fly, we recommend Folder Lock.
It applies military-grade AES-256 encryption to specific folders, allowing you to lock them with a master password without the hassle of mounting virtual drives. It works smoothly alongside FileVault to provide data-in-use protection.
When you choose a third-party tool like our recommended pick, you gain features that native macOS tools do not offer natively.
Dedicated Cloud Lockers
Instead of manually encrypting files before uploading them, modern tools integrate directly with Dropbox, Google Drive, and OneDrive. They create specific, secure vaults within your cloud storage, ensuring your data is scrambled before it ever leaves your Mac.
Cross-Ecosystem Synchronization
A major limitation of Apple's built-in tools is their restriction to the Apple ecosystem. Premium third-party software bridges this gap, allowing you to seamlessly sync and access your encrypted vaults across Mac, Windows, iOS, and Android devices.
Password-less Secure Sharing
Sharing locked files usually involves the dangerous practice of sending passwords over email or text. Advanced Mac encryption software utilizes asymmetric cryptography, allowing you to share locked documents with authorized colleagues who open them using their own secure credentials.
Digital Wallets & Secret Notes
Not all sensitive data exists as a standalone file. A robust security suite includes a dedicated space to safely stash text-based secrets, such as credit card numbers, banking credentials, and private notes, shielding them from local prying eyes and keyloggers.

How Modern Encryption Algorithms Work
When searching for the best encryption software for Mac, you will constantly see the term AES-256. Advanced Encryption Standard (AES) is a symmetric block cipher adopted by the U.S. government.
AES-128 vs AES-256
macOS FileVault uses AES-128 by default, which is highly secure and incredibly fast. However, AES-256 uses a larger key size, offering exponentially more combinations. For enterprise environments handling HIPAA, GDPR, or PCI-DSS data, AES-256 is the required compliance standard.
Symmetric vs. Asymmetric Encryption
While AES-256 is incredible for storing data locally (symmetric encryption, where one key locks and unlocks the file), it presents a challenge when you need to share that file. If you email an AES-encrypted document, you also have to give the recipient the password, which is a massive security risk.
Top-tier third-party tools solve this by combining AES with Asymmetric Encryption (like RSA) for file sharing. This system uses a mathematical public and private key pair. It allows you to lock a file specifically for a colleague so that they can open it using their own unique account credentials, entirely eliminating the need to transmit vulnerable passwords over the internet.

Hardware vs Software Encryption Tradeoffs
Some external SSDs (like the Samsung Portable SSD T7) come with built-in hardware encryption. This is incredibly fast as the drive handles the cryptography. However, if the drive's firmware has a vulnerability, it cannot easily be patched. Software encryption (like Disk Utility or Folder Lock) relies on your Mac's CPU but offers transparent security updates.
Troubleshooting & Owner Verification
Encryption works so well that if you lose your credentials, your data is gone. Here is how to handle common lockouts safely.
How to recover access to a locked folder you own
If you used Disk Utility to create an encrypted DMG and forgot the password, check your macOS Keychain. Often, users leave "Save password in my keychain" checked during creation. Open the Keychain Access app and search for the name of the DMG file.
Forgot your Folder Lock master password?
Legitimate encryption software does not contain "backdoors" for customer support to unlock your files. If you lose your master password, you must rely on the backup keys generated during your initial setup. If those are lost, the AES-256 encryption cannot be cracked by brute force.
macOS zip -e encryption type: zipcrypto or AES?
If you use the terminal command zip -e archive.zip folder/ on a Mac, be aware that the built-in macOS zip utility uses the older, less secure ZipCrypto algorithm by default, not AES. To use AES-256 on ZIP files, you must use a third-party tool.
Pricing: Free vs Paid Options
Are paid encryption tools worth it? If you are comfortable using the Terminal or managing disk image mounting via Disk Utility, you do not need to spend money. Native Mac tools and open-source software like VeraCrypt are entirely free.
However, if you want drag-and-drop simplicity, seamless cloud integration without exposing your keys, and dedicated customer support, a premium solution is worthwhile.
Most commercial Mac security suites operate on a freemium model. For instance, our recommended tool, Folder Lock, allows you to download a fully functional free version that restricts your secure storage capacity to 1GB and limits synchronization to two devices. If your security needs grow, a one-time lifetime license of $39.95 unlocks unlimited data encryption, expands syncing to up to five devices, and activates advanced collaboration features.
For whole-device protection, macOS FileVault is the best option. For securing specific files, folders, or cloud uploads, a dedicated AES-256 application like Folder Lock provides the necessary data-in-use protection.
Does Mac have built-in encryption software?
Yes. macOS includes FileVault for full disk encryption and Disk Utility for creating encrypted disk images (DMG files). Terminal also allows basic ZIP encryption, though it uses older algorithms natively.
Should I use FileVault disk encryption on my Mac?
Yes. Turning on FileVault is highly recommended for all Mac users, especially on laptops. It has negligible performance impact on modern Macs and ensures your data is unreadable if the physical device is stolen.
How does full disk encryption differ from file-level encryption?
Full disk encryption unlocks everything the moment you log into your computer. File-level encryption requires a separate password to unlock specific files, keeping them safe even while you are actively using the computer.
