macOS has built-in features like XProtect, Gatekeeper, and System Integrity Protection (SIP). These are great first lines of defense, but they don’t cover everything. For example:
Adware and browser hijackers can still slip in through unsafe downloads.
Phishing attacks trick users into giving away sensitive data.
Trojans and ransomware can disguise themselves as legitimate apps.
Zero-day exploits can bypass built-in protections before Apple releases a fix.
Keep macOS Updated
Apple regularly releases security updates. Always install them promptly to stay protected against the latest threats.
Use a Trusted Antivirus for Mac
Consider lightweight, reputable antivirus software like:
Malwarebytes for Mac
Bitdefender Antivirus for Mac
Intego Mac Premium Bundle
Avoid Untrusted Downloads
Only install apps from the Mac App Store or verified developers. Avoid cracked or pirated software—it’s often loaded with malware.
Enable Gatekeeper
Gatekeeper prevents unsigned apps from running without your permission. Leave it enabled in System Settings > Privacy & Security.
Be Cautious with Email Links and Attachments
Phishing remains one of the most common threats. Always verify links before clicking and never download unexpected attachments.
Use a Standard (Non-Admin) Account for Daily Use
This limits what damage malware can do if it does infect your system.
Enable Firewall & FileVault
Firewall blocks unwanted incoming connections.
FileVault encrypts your entire disk to protect your data even if your device is lost or stolen.
Unusual pop-ups or browser redirects
Apps you don’t remember installing
Sluggish performance or overheating
Warnings telling you to “clean your Mac” or “update now”
If you see any of these, run a malware scan immediately.
