macOS now scans for malware whenever it gets a chance
In the last six months macOS malware protection has changed more than it did over the previous seven years. It has now gone fully pre-emptive, as active as many commercial anti-malware products, provided that your Mac is running Catalina or later. This article updates those I've previously written about Apple's new tool in the war against malware, XProtect Remediator.
Apple has been slowly building out its anti-malware and antivirus tools in macOS, and it has remained mostly quiet about it - understandable considering how bad tech press would have a field day with stories about Apple effectively turning macOS malware protection into a regular antivirus scanner.
