Apple's Safari browser added phishing and malware blocking in version 3.2, which was released in late 2008; read about this and other security features in Safari 4 on the Apple Safari site. In this video, you'll learn more about privacy and security in Safari. Visit for our te. The good news is your web browser has a lot of built-in security features to help protect your computer. Let's take a look at some of the most important features you should know about, as well as some simple tips you can use to stay safe online. Watch the video below to learn more about your browser's built-in security features.
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 Big Sur available as a free upgrade, it's easy to get the most secure version of macOS for your Mac.*

Apple M1 chip.
A shared architecture for security.
The Apple M1 chip with built-in Secure Enclave brings the same powerful security capabilities of iPhone to Mac — protecting your login password, automatically encrypting your data, and powering file-level encryption so you stay safe. And the Apple M1 chip keeps macOS secure while it's running, just as iOS has protected iPhone for years.
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 and starts applying them in the background, so it's easier and faster than ever 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.
Chrome Security Features
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.
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. Mac computers built on the Apple M1 chip take data protection even further by using dedicated hardware to protect your login password and enabling file-level encryption, which developers can take advantage of — just as on iPhone.
Designed to protect your privacy.
Online privacy isn't just something you should hope for — it's something you should expect. That's why Safari comes with powerful privacy protection technology built in, including Intelligent Tracking Prevention that identifies trackers and helps prevent them from profiling or following you across the web. A new weekly Privacy Report on your start page shows how Safari protects you as you browse over time. Or click the Privacy Report button in your Safari toolbar for an instant snapshot of the cross-site trackers Safari is actively preventing on that web page.
Automatic protections from intruders.
Safari uses iCloud Keychain to securely store your passwords across all your devices. If it ever detects a security concern, Password Monitoring will alert you. Safari also prevents suspicious websites from loading and warns you if they're detected. And because it runs web pages in separate processes, any harmful code is confined to a single browser tab and can't crash the whole browser or access your data.
Find your missing Mac with Find My.
The Find My app 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. Does cyberlink powerdirector have a watermark. These devices then relay the detected location of your Mac to iCloud so you can locate it. 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. 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.
Keep your Mac safe.
Even if it's in the wrong hands.
All Mac systems built on the Apple M1 chip or 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.
macOS Security
When browsing the net, I'm safest when I'm using Mozilla's Firefox 3.0 browser—at least after I've tweaked it just a bit. Yup, I have absolutely no doubt about it. I've looked at others, and I'm sticking with Firefox.
But instead of just taking my word for it, let's take a closer look at why I believe this to be true. First, let me describe the contestants.
As I'm principally a Mac user (Leopard 10.5.4), I'm mainly concerned with Firefox and Apple's own Safari browser, but I'll also compare them against Microsoft's Internet Explorer (IE). I should also note there are significant other options available, not the least of which is the highly-regarded Opera browser. For now, though, I'm going to stick with the top 3 in my comparison: Firefox, Safari, and IE.
As with the comparisons I've done here of Windows vs. Linux vs. OS X security, I'm going to explore various user-level differences between the browsers. I do believe, after all, that the determined tech-savvy user would be able to use any of these three browsers quite securely.
Out-of-the-Box Configuration
In their own ways, all three of these browsers are delivered in an overly trusting configuration. If you're serious about being secure in your Web browsing habits, it's clear you'll need to spend some time fine-tuning each of these products. Despite their claims of providing security features (see below), when you install these products, they make some serious mistakes.
Chief among the default mistakes is allowing active content (e.g., Javascript, ActiveX) to run by default, from just about any site you might connect to. This, by the way, is the single most important thing to control if you want to make your browser more secure. Nonetheless, I have to give a slight nod here to Firefox for its 'safe browsing' feature as well as IE for its security zones, including an 'Internet zone' which is at least slightly untrusted.
Qualitative Score: Firefox gets a D, Safari an F, and IE a D.
Security Features:
All three browsers offer some rudimentary security controls in the way of being able to allow or disallow broad categories of content, such as Javascript, Java, or ActiveX. But by default, these features are so broad in their 'all or nothing' approaches as to be next to worthless.Turning off Javascript, for example, just doesn't work. Today's Internet applications, by and large, require Javascript in order to run, so I need to enable that for sites I want to do business with. On the other hand, uncontrolled Javascript is a boon to all types of miscreants who want to attack my computer.
Beyond that, IE's security zones are actually a pretty powerful mechanism for controlling Web content and how it interacts in the browser. Unfortunately, to really get the power from the security zones requires a learning curve that few users will be willing or able to overcome. Firefox's 'safe browsing' feature works in conjunction with an external site (run by Google) to blacklist various Internet sites that are thought to be harboring phishing attacks and other nasties. This is turned on by default, and most users needn't even be aware it's there.
Unfortunately, it's fundamentally a negative validation model that is doomed to eventual failure—think anti-virus signature updates. So this category is a tough call, since all three products are pretty awful.
Qualitative Score: Firefox gets a C, Safari a F and IE a D.
