This means that hackers and websites cannot trace your connection and find your exact location, making you semi-anonymous online. This will ensure your online activities are encrypted and not seen by potential online attackers.
The easiest way to back up data is by setting up Time Machine, which backs up all the information on your Mac automatically every day. Apple provides guidance on how to do this here. Macs, just like PCs, go missing and get stolen. As well as backing up your data, make sure your Mac is password-protected, kept in a safe place, and set up with Find My Mac.
Pay attention to Gatekeeper alerts, as they will help minimize the risk of inadvertently downloading malware. Exercise caution when it comes to browser plug-ins and add-ons.
Check all installation clients for bundled items by opting out of the default setup option and selecting custom mode instead. Avoid opening spam emails and unknown attachments to avoid falling victim to a phishing attack.
Avoid downloading any files whose source may be questionable. An ad blocker blocks or alters online advertising within a web browser or application. This may be done using browser extensions or other methods.
Avoid clicking on pop-ups or virus warnings. Many of these windows are scams and designed to trick users into thinking you have already contracted a virus. For example, Kaspersky Internet Security for Mac protects against a range of online attacks — including the latest threats — and safeguards your privacy and personal information.

What online threats can affect Macs? They include: Viruses A virus is a malicious software program loaded onto a user's computer without the user's knowledge that performs malicious actions. Adware This malware takes over your computer, bombarding it with numerous ads and pop-ups that can harm your device, track you, and slow down performance.
Trojans Trojan horses are a type of malware that tricks you into downloading and installing them by posing as something else. Rootkits A rootkit is a type of malware designed to give hackers access to and control over a target device. Spyware Spyware is a computer program that hackers can use to spy on you and secretly follow your online activities.
Cryptomining Cryptomining — sometimes called cryptojacking — refers to malware that uses your Mac's computing power to mine cryptocurrencies for the attacker. Phishing Phishing is a form of social engineering which involves cybercriminals impersonating a known entity or close connection to trick you into revealing sensitive personal information that can be used for identity fraud or financial theft.
Do Macs have built in antivirus? However, Apple has several anti-malware features, including: XProtect - Apple has all the known malware definitions in its XProtect file, which sits on your Mac, and every time you download a new application, it checks that none of those definitions are present. Gatekeeper - Apple's Gatekeeper software blocks apps created by malware developers and verifies that apps have not been tampered with.
If you were to install something from an unknown developer, Apple would warn you to check its authenticity. How to tell if your Mac has a virus If your MacBook has been infected by a virus or malware, here are some signs to look out for: Slower performance: If your device or specific apps have started to operate slowly, this could be a sign of trouble. And then, it just is a Windows machine. When you look at the market share bar graph above that Windows computers have and see how they stack up against the number of OS X computers, this begins to become clear.
Like any business investment, malware and viruses take time and manpower to develop. Because they are organized, you can think of them as a business as well. They want the best possible return on the investment of this time and manpower, so it makes the most sense to cast the widest net and go for Windows machines, simply because many many more computers in the world are going to be running Windows.
It still makes the most sense to develop viruses for the largest platform for the biggest return on investment. Meet Charlie Miller. Charlie became a famous name in security cracking by winning prizes and cracking a MacBook Air in a hack that took him a paltry two minutes to perform. Pwn2Own is a conference where security crackers compete by finding flaws in operating systems, browsers, etc.
While Charlie did manage to compromise the security in an incredibly short amount of time no easy feat he was only able to do it with lots of hard work and preparation.
In his own words, Charlie says:. Security through minority seems to be working for Mac, even for security experts like Charlie. There are less than pieces of malware targeting the Mac.
Viruses on Macintosh computers are a reality. The biggest threat to compromising the security of a machine is often the user, so arm yourself with information!
As time progresses on, it seems inevitable that any platform that is as popular as Mac will enjoy years and years of users carelessly using the internet with no repercussions. Two things could happen to make attacks on Macintosh computers more common.
Looking at the numbers above fairly recent compared to the writing of this article we see that Apple still has a long way to go to reach that goal.
While the Windows market is likely to grow faster in a world where more and more people are starting to use the internet, in a world where even more people are using computers, even more people should be using Macs. Will be begin to see niche profit-driven viruses? It seems very plausible—security through minority will probably not work forever.

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.
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. 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. These devices then relay the detected location of your Mac to iCloud so you can locate it.
And it all happens silently using tiny bits of data that piggyback on existing network traffic. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
