Sierra Without App Store Update That AppleApple has not previously responded to press inquiries about this subject. Keeping up with the latest macOS updates and using third-party antivirus and security software ( might we recommend some?) are important factors in keeping your Mac protected.Apple does not make any public statements concerning how long it will continue to release XProtect updates, let alone security patches, for any particular Apple software or operating system.While Microsoft publicly announces its support timetables for Windows and other software, and the Ubuntu Linux company Canonical does likewise, Apple has never given any official notice regarding how long each version of macOS or iOS will continue to receive security updates. For now, Flash and Java also officially support Mavericks and later.Browsers and plugins are commonly exploited as a means of infecting computers, so it’s critical that these programs—along with the operating systems that run them—stay up to date.The only security-related update that Apple is continuing to release for Snow Leopard through Mavericks is the XProtect “Safe Downloads List,” which blocks a handful of malicious downloads (although signatures are often added too late to be of much use) and prevents Flash and Java content from running in your browser—if your plug-ins are too outdated and likely to be exploited.It’s important to note that XProtect updates, while better than nothing, are by themselves insufficient to adequately protect your Mac.

Worse, when users check the App Store for updates (or on older Macs when users run Software Update), it misleadingly tells them, “No Updates Available” or “Your software is up to date.” This means that Mac users often have no idea that they’re using unpatched, insecure software that could expose them to drive-by malware installations and other security problems.“Your software is up to date.” …Except it isn’t.Lest you think that nobody would bother releasing malware to attack such old systems, in recent years malware has been found in the wild that was designed to attack multiple platforms, and occasionally this malware has contained code capable of infecting old operating systems and even Macs with PowerPC G4/G5 processors (Apple’s processors of choice prior to transitioning to Intel in 2006).
