If you wish to upgrade your Operating System, you can follow the guide here: How to Upgrade Mac OS X If you need your Mac rebuilt with a new Faculty/Staff Image with the latest Operating System, please submit a Tech Support Request at
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.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.Although the same could be said for i Tunes updates, Apple has a financial incentive to keep i Tunes updated: the i Tunes Store and the i OS App Store, both of which are accessible via the i Tunes 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.Of course, Apple no longer releases security updates for Leopard (Mac OS X version 10.5.8), Tiger (version 10.4.11), or anything older than that, either.
If you still use a Mac with a Power PC 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.
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): If Lion is the newest version of OS X that will run on your Mac, but you never purchased it while it was available in the Mac App Store, you won't be able to find it for sale there anymore.
Like last year with the release of Mavericks, Apple chose to continue supporting all the same Macs as the previous release of the operating system.
This means that if your Mac was compatible with Mavericks or even its predecessor Mountain Lion, you'll be able to upgrade to Yosemite.
Also note that Apple updates will only install for your current Operating System and will not upgrade you to a new OS.
