Development of OS patches costs Apple money and developer resources. Although the same could be said for iTunes updates, Apple has a financial incentive to keep iTunes updated: the iTunes Store and the iOS App Store, both of which are accessible via the iTunes Mac app, bring in a lot of revenue for Apple.

Unfortunately, nobody knows for certain how long Apple will continue to release security patches or XProtect updates for any given operating system. Although Microsoft publicly announces its support timetables for Windows, and the Ubuntu Linux company Canonical does likewise, Apple has never given any official word to the public regarding how long each version of Mac OS X or iOS will continue to receive security updates, and Apple consistently ignores press inquiries about when levels of support will be dropped for its operating systems.

The good news is that most new Macs sold within the past several years can be upgraded to Yosemite. Following is the list of Macs that can run a supported version of OS X. If your Mac is older than the ones listed, read on for suggestions on what you can do to upgrade to a supported system.

You can do a direct upgrade from Snow Leopard v If you still have an earlier version of OS X on your compatible Mac, you will need to download Yosemite on another compatible Mac with If your Mac isn't new enough to run Yosemite, then unfortunately it's not capable of running an Apple operating system that's still fully supported.

However, if your Mac has a Core 2 Duo processor one of the models listed below , and as long as it has at least 2 GB of RAM and 7 GB of free hard drive space, it should still be able to run Lion which, although increasingly less safe to use now, is at least better than Snow Leopard or earlier because it had been getting security updates until recently :.

RAM is cheap, and you can either install it yourself by following guides available online, or simply have an Apple-authorized repair technician do it for you.

Remember, even Lion isn't supported anymore, and Snow Leopard hasn't gotten new security updates for quite a while, so it's best to avoid using both of these older operating systems.

If you still use a Mac with a PowerPC processor, including G4 or G5 Macs, Apple hasn't released any security updates for your Mac's maximum operating system for over three years now. Apple hasn't sold any PowerPC-based Macs since Unfortunately, Apple doesn't give users any kind of warning when their operating system or Mac is no longer supported.

Worse, when users run Apple's Software Update program, it misleadingly tells them "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. 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 PowerPC native code.

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. That's not terrible given that it's been out for less than a month. This makes non-upgraded Macs a potentially significant target for criminals interested in infecting large numbers of computers.
