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. It's important to note that XProtect updates, while better than nothing, are by themselves insufficient to adequately protect your Mac.

Keeping up with the latest macOS updates and using third-party antivirus and security software might we recommend some? 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.
Apple has not previously responded to press inquiries about this subject. The good news is that most new Macs sold within the past several years can be upgraded to Sierra. Following is the list of Macs that can run Sierra, the current and best-supported version of macOS.
FAQ: Everything you need to know about OS X Mavericks
If your Mac is older than the ones listed directly below, read on for suggestions about what you can do to upgrade to an operating system that's still getting security patches. Those who are unsure which Mac model they own may find EveryMac and apple-history to be useful sites. If you have a compatible Mac with a version of OS X that predates Lion for example, Snow Leopard , you will need to download Sierra on another compatible Mac with Lion or later, create a bootable Sierra flash drive or external hard drive using Apple's official instructions or the third-party tool DiskMaker X , and do a clean install overwriting the hard drive on your Mac—so be sure to carefully back up all of your files first.
An alternative solution for upgrading a compatible Mac from Snow Leopard to Sierra is to first upgrade to your choice of Lion through El Capitan if you happen to have a bootable installer from one of those versions of macOS handy, or if you're able to download one from the Purchased section of the App Store and use DiskMaker X to create a bootable installer , and then do a second upgrade from that macOS version to Sierra. Taking this upgrade path will allow you to preserve your hard drive's contents.
macOS Catalina: Everything you need to know
If your Mac can't run Sierra, there's still a decent chance that it can run the previous version of macOS, El Capitan, which may continue to receive security updates from Apple for another year or two. If your Mac is currently running Mountain Lion, Mavericks, or Yosemite, then it definitely meets the minimum system requirements for running El Capitan and it might even be Sierra-capable; refer to the previous section. If your Mac isn't new enough to run Sierra or even El Capitan, then, unfortunately, it will no longer receive much support from Apple. Sadly, Apple doesn't give users any direct warning when their operating system or Mac is no longer supported.
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.
OS X Mavericks Minimum Hardware System Requirements
This didn't just happen once ; it has happened again and again. Universal binary malware can run on old Macs, too. Image credit: Kaspersky. While Apple boasts about the extremely high percentage of iPhone, iPad, and iPod touch devices that are rapidly upgraded to each major new version of iOS, such is not necessarily the case with Macs and OS X. Based on the newly released Net Applications data for November , it appears that Sierra has been installed on nearly one third of the Macs that were used for Web browsing last month.
Meanwhile, El Capitan, which has been out for over a year and is still being supported, is currently tied with Sierra at one third of the Mac market share, and Yosemite is in third place at just over one-fifth of the active installed base. All older versions of OS X, though, together comprise more than In other words, about 1 in every 7 Macs in use today is no longer getting security updates.
This makes non-upgraded or non-upgradeable Macs a potentially significant target roughly 20 to 30 million computers for criminals interested in infecting a large quantity of devices.

If I remember correctly it came with Leopard but I bought Snow Leopard on the same day, or just afterwards. Earlier this year Apple stopped supporting Snow Leopard with security updates in my opinion, I know others disagree. Understandable, somewhat, and while I knew I could update it to Lion I had never really come around to doing so. As a somewhat Internet facing machine I felt I needed to make sure it at least got security updates, and thus I upgraded it to Lion yesterday.
It was a huge pain freeing up enough space on the internal SSD to be able to remove the per user FileVault encryption — but eventually I got it done. And realized way too late that turning on full disc encryption with FileVault 2 kind of defeated the purpose of having a headless NAS in a closet — since any reboot now meant I had to connect at least a keyboard, possibly a screen. Lion is the end-of-the-line when it comes to OS support for my Mac Mini 2,1.
