Does Mac Need Antivirus?
Mac running on the latest macOS has built-in security features such as XProtect, Gatekeeper, Notarization, and Sandboxing. These security features protect your Mac from various Internet threats. So, you might think that there is no need for antivirus. Read on to know.
School of thought
There is an age-old belief that Mac systems don’t get viruses, meaning Mac is less susceptible to malicious software than Windows PC. Is the view accurate? Not exactly, we’ll share the reasons.
There wasn’t any need for antivirus software a decade ago
You didn’t require antivirus software for your Mac 10 years back because the built-in security feature in macOS was sufficient to protect your computer from any unauthorized intrusion from the Internet or otherwise.

Mac users have increased, and several new threats specifically targeted at Mac have been revealed in the recent years.
There are gaps in the armor of Mac users’ systems. The macOS layer of security depends on Apple that adds virus signatures. So, you get a warning message when you are unknowingly going to open a virus-infected program or file. But the defence mechanism isn’t all-encompassing. XProtect list of virus signatures is trivial compared to the checks a robust antivirus software applies. So, a powerful antivirus software is the need of the hour for all Mac users.
Does Antivirus Slows Down Mac?
Yes, antivirus software does slow down your Mac performance. Also, sandboxing on macOS restricts antivirus software from performing optimally. Antivirus software might start as a login item and periodically scan the system, which is resource-driven and time-consuming. This automatic scanning process also reduces the Mac performance in most cases.
