Apply security updates and system software upgrades as soon as they become available. And remember that a Mac can carry a virus and pass it to other computers even if it is not affected itself. Check for updates by going to the System Preferences application. Malware isn’t the only threat to your Mac. Malicious websites and vulnerable Wi-Fi networks can also jeopardize your safety. Avast Security provides essential free protection against all 3 threats, and our new Premium version goes the extra mile to expose Wi-Fi intruders and stop ransomware.

If you’re a system administrator, review these documents to prepare for iOS 13 and macOS Catalina.

End-of-Life for SHA-1 Certificate Support

In 2017, a security update to Apple’s operating systems removed support for SHA-1 signed certificates used for Transport Layer Security (TLS) in Safari and WebKit. Make sure to use SHA-256 signed certificates.

Making Secure Connections

A range of APIs on Apple platforms enable your apps to employ secure network connections and to benefit from OS-level security policies.

App Transport Security (ATS)

ATS establishes best-practice policies for secure network communications using Apple platforms, employing Transport Layer Security (TLS) version 1.2, forward secrecy, and strong cryptography.

Secure Transport API

Use Apple’s secure transport API to employ current versions of the Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Datagram Transport Layer Security (DTLS) cryptographic protocols for network communications.

Supported Algorithms

Starting with iOS 10 and macOS v10.12, the RC4 cipher suite is disabled by default. In addition, Apple recommends that your servers use certificates signed with the SHA-2 cryptographic function.

DeviceCheck and the App Attest API

Protect against security threats to your iOS apps and reduce fraudulent use of your services by managing device states and asserting app integrity. The DeviceCheck services provide information that you can integrate into an overall anti-fraud strategy for your app and risk assessment for a given device.

Using the DeviceCheck service, a token on your server can set and query two binary digits of data per device — for example, to flag a device you‘ve determined to be fraudulent — while maintaining user privacy. And with App Attest, you can generate a special cryptographic key on a device running iOS 14 or later, and use that key to validate the integrity of your app before your server provides access to sensitive data.

Certificate Transparency and Certificate Trust APIs

Strong encryption for your network connections is not enough. To help ensure your app is connecting to the right server, employ Apple’s certificate trust APIs and Certificate Transparency.

Protecting User Data

Apple platforms provide a variety of features for protecting user data.

Purpose Strings


Purpose strings let you statically declare the sensitive data and resources your app employs.

Copying and Pasting Sensitive Data

Copying and pasting sensitive data in iOS can take advantage of privacy options.

Internet security for mac

Keychain and iCloud Keychain

Keychain and iCloud Keychain provide a secure repository for sensitive user data, such as certificates, keys, passwords, and notes.

App Sandboxing

Protect Mac systems and users by limiting the privileges of an app to its intended functionality, increasing the difficulty for malicious software to compromise users’ systems.

Executing Code Securely

Apple platforms protect users with secure code execution. Xcode, Apple’s integrated development environment (IDE), directly provides code signing for iOS, watchOS, and tvOS apps, as well as for macOS apps that you distribute through the Mac App Store.

Sign Your Apps with Developer ID

Gatekeeper on macOS helps protect users from downloading and installing malicious software distributed outside the Mac App Store by checking for a Developer ID certificate.

Notarize Your Apps

If distributing your Mac app outside of the Mac App Store, sign and upload your app to Apple to be notarized to certify your app is genuine and to perform a security check.

Cryptographic Interfaces

Apple platforms offer a comprehensive set of low-level APIs for developing cryptographic solutions within your apps.

Apple CryptoKit

Perform cryptographic operations securely and efficiently in your app.

Common Crypto Library

The Common Crypto library supports symmetric encryption, hash-based message authentication codes, and digests.

CryptoTokenKit for Smart Card Support

The CryptoTokenKit framework provides first-class access for working with smart cards and other cryptographic devices in macOS.

SecKey API for Asymmetric Keys

SecKey provides a unified asymmetric key API across Apple platforms.

Security Fundamentals and Resources

These resources provide background information and support for security on Apple platforms.





Both Security Framework and Common Crypto rely on the corecrypto library to provide implementations of low level cryptographic primitives. This is also the library submitted for validation of compliance with U.S. Federal Information Processing Standards (FIPS) 140-2 Level 1. Although corecrypto does not directly provide programming interfaces for developers and should not be used by iOS or macOS apps, the source code is available to allow for verification of its security characteristics and correct functioning.

We design Mac hardware and software with advanced technologies that work together to run apps more securely, protect your data, and help keep you safe on the web. And with macOS Catalina available as a free upgrade, it’s easy to get the most secure version of macOS for your Mac.*

Apple T2 chip.
The next generation of security.

The Apple T2 Security Chip — included with many newer Mac models — keeps your Mac safer than ever. The Secure Enclave coprocessor in the Apple T2 chip provides the foundation for Touch ID, secure boot, and encrypted storage capabilities. Touch ID gives you a seamless way to use your fingerprint to unlock your Mac, fill passwords in Safari, and make purchases with Apple Pay. Secure boot helps ensure that you are running trusted operating system software from Apple, while the Apple T2 chip automatically encrypts the data on your Mac. So you can be confident knowing that security has been designed right into the architecture of your Mac, from the ground up.

Apple helps you keep your Mac secure with software updates.

The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. macOS checks for new updates every day, so it’s easy to always have the latest and safest version.

Protection starts at the core.

The technically sophisticated runtime protections in macOS work at the very core of your Mac to keep your system safe from malware. This starts with state-of-the-art antivirus software built in to block and remove malware. Technologies like XD (execute disable), ASLR (address space layout randomization), and SIP (system integrity protection) make it difficult for malware to do harm, and they ensure that processes with root permission cannot change critical system files.

Download apps safely from the Mac App Store. And the internet.

Now apps from both the App Store and the internet can be installed worry-free. App Review makes sure each app in the App Store is reviewed before it’s accepted. Gatekeeper on your Mac ensures that all apps from the internet have already been checked by Apple for known malicious code — before you run them the first time. If there’s ever a problem with an app, Apple can quickly stop new installations and even block the app from launching again.

Stay in control of what data apps can access.


Apps need your permission to access files in your Documents, Downloads, and Desktop folders as well as in iCloud Drive and external volumes. And you’ll be prompted before any app can access the camera or mic, capture keyboard activity, or take a photo or video of your screen.


FileVault 2 encrypts your data.

Security For Apple Imac

With FileVault 2, your data is safe and secure — even if your Mac falls into the wrong hands. FileVault 2 encrypts the entire drive on your Mac, protecting your data with XTS-AES 128 encryption. And on Mac systems with an Apple T2 Security Chip, FileVault 2 keys are created and protected by the Secure Enclave for even more security.

Designed to protect your privacy.

The most secure browser for your Mac is the one that comes with your Mac. Built-in privacy features in Safari, like Intelligent Tracking Prevention, help keep your browsing your business. Automatic strong passwords make it easy to create and use unique passwords for all the sites you visit. And iCloud Keychain syncs those passwords securely across all your devices, so you don’t have to remember them. You can also easily find and upgrade any weak passwords you’ve previously used (and reused and reused and reused).

Automatic protections from harmful sites.

Safari also helps safeguard you against fraudulent websites and those that harbor malware — before you visit them. If a website seems suspicious, Safari prevents it from loading and notifies you. And when connecting to unencrypted sites, Safari will warn you. So everything you need to browse without worry is right at your fingertips.

Find your missing Mac with Find My.

Best Security For Apple Macbook Pro

The Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app on Mac, iPad, and iPhone. Find My can help you locate a missing Mac — even if it’s offline or sleeping — by sending out Bluetooth signals that can be detected by nearby Apple devices. These devices then relay the detected location of your Mac to iCloud so you can locate it in the Find My app. It’s all anonymous and encrypted end-to-end so no one — including Apple — knows the identity of any reporting device or the location of your Mac. Make a bootable disk for mac. And it all happens silently using tiny bits of data that piggyback on existing network traffic. So there’s no need to worry about your battery life, your data usage, or your privacy being compromised.

Security For Apple Macbooks

Keep your Mac safe.
Even if it’s in the wrong hands.

Best Security Software For Apple Mac

All Mac models with the Apple T2 Security Chip support Activation Lock — just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
