We have all sat down at our computer to be notified that there is a software update that needs to be downloaded. If these are security upgrades, they should be upgraded quickly, to make sure your system remains safe from the latest forms of attack.

Last week, we covered the latest security upgrade that was released by Apple. This came in the wake of the announcement that a massive security flaw has been discovered in both iOS and Mac OS X operating systems. However, there was an interesting caveat to the update: there wasn't one for OS X 10.6, better known as Snow Leopard.

According to an article from Entrepreneur, this confirms speculation that Apple is no longer supporting the older operating system, instead focusing on Mavericks (OS X 10.9), Mountain Lion (OS X 10.8) and Lion (OS X 10.7).

Companies stopping security support for an older operating system—Snow Leopard was released on June 8, 2009—is not unheard of, as it cost time and money to upgrade. The issue for Apple users is that 20 percent of them still use Snow Leopard, citing that it still works fine or that they do not like the direction that Apple went with the newer operating systems.

"But from a security standpoint, upgrading to an operating system that receives regular updates is the smart thing to do," the article reads. "Now that Snow Leopard is no longer being patched, the vulnerabilities hackers find could be used to take over a computer, spy on users and steal sensitive information."

For a business that was using Snow Leopard, a system wide update can seem daunting. With the help of a Mac IT support service, any company will be able to successfully ensure the security of their computer system.
