A virus could cause your Mac running OS X Mountain Lion to misbehave. A computer virus is a nasty little piece of computer code that replicates and spreads from disk to disk; some viruses can destroy files or erase disks with no warning.
Malware (short for malicious software) is software that’s hostile, intrusive, annoying, or disruptive. Malware is often designed to gain unauthorized access to your computer and/or collect personal data (including passwords) without your knowledge.

- The Bottom Line. Vipre Advanced Security for the Mac is a bare-bones antivirus app for Apple users. It doesn't protect against phishing sites, yet it costs more than the competition.
For Mac OS 10.8 (Mountain Lion) - 10.15 (Catalina) (last updated November 15, 2019) Release Update (RU) is for people performing a new install or upgrading from an earlier release or build of the product.
The difference between a virus and other types of malware is that malware doesn’t spread by itself. It relies upon trickery, mimicry, and social engineering to induce unsuspecting users to open a malicious file or install a malicious program. Pogil biochemistry basics key. So a virus is a type of malware, but not all malware is viral.
You don’t hear much about viruses on the Mac because there have been few (if any) since the dawn of the modern OS X era (so many big cats ago). Almost all viruses are specific to an operating system — Mac viruses won’t affect Windows users, Windows viruses won’t affect Mac users, and so forth, and the vast majority of known viruses affect only (you guessed it) Windows.
The one real exception here is a “gift” from the wonderful world of Microsoft Office (Word and Excel, for example) users: the dreaded macro viruses that are spread with Word and Excel documents containing macros written in Microsoft’s VBA (Visual Basic for Applications) language. But you’re safe even from those if you practice safe computing (although you can unknowingly pass them along to Windows users).
As it happens, so far, much of the viral activity affecting OS X involved various Windows macro viruses. Sadly, a very real threat known as Flashback appeared in early 2012. It exploited a security flaw in Java and stealthily installed itself on Macs. Soon after its discovery, Apple issued software updates for OS X that removed the malware and corrected the security flaw.
By default, your Mac automatically checks for software updates every week, but you can change that setting in the Software Update System Preference Pane. Click the Check Now button to run Software Update manually and check for the latest updates. The moral of the story is that it’s usually a good idea to install Apple updates sooner rather than later.
So while there was at least one piece of truly malicious software spotted in the wild, others are spread mostly via social engineering. So here’s how to protect yourself:
- Disable Open Safe Files after Downloading in Safari Preferences.
- If a suspicious alert or window appears on your screen, Force Quit your web browser (Apple→Force Quit or Command+Option+Esc) immediately.
- If the OS X Installer launches for no apparent reason, do not click Continue! Don’t install the software, and for heaven’s sake, don’t type your administrator password.
- How to change app icons for mac. Don’t run any installer — the one built into OS X or a third-party kind — unless you’re absolutely certain that it came from a trusted source.
- Don’t use credit or debit cards with unfamiliar vendors and/or insecure websites.
If you use disks that have been inserted into other computers, you need some form of virus-detection software. If you download and use files from web and File Transfer Protocol (FTP) sites on the Internet, you need some form of virus detection as well.
You don’t have too much to worry about if
- You download files only from commercial online services, such as AOL, CNET, or MacUpdate, which are all very conscientious about malware.
- You use only commercial software and never download files from websites with strange names.
Volkswagen routan owners manual. You should definitely worry about malicious infection if
- An unsavory friend told you about a website called Dan’sDenOfPiratedIllegalStolenBootlegSoftware.com, and you actually visited it.
- You swap disks or USB thumb drives with friends regularly.
- You shuttle disks or USB thumb drives back and forth to other Macs.
- You use your disks or USB thumb drives at public computers or printing shops.
- You download files from various and sundry places on the Internet, even ones that don’t sound as slimy as Dan’sDenOfPiratedIllegalStolenBootlegSoftware.com.
- You receive e-mail with attachments (and open them).
If you’re at risk, do yourself a favor, and buy a commercial antivirus program. If you think you need protection, consider VirusBarrier X6 ($49.95), MacScan ($29.99), or ClamXAV (free).
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.
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.
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. 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 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.
