Apple has had a busy week updating its software across every gadget. In the process, it's fixed several security bugs, including one in iMessage that could have opened the door for hackers to spy on your photos and videos.

However, we've now learned from tech giant Cisco that Apple fixed an even bigger problem in OS X. This bug could have easily let a hacker take full control of a Mac computer, which means if you haven't updated OS X yet this week, you should.

The flaw was found in the OS X graphics driver. Using a malicious PDF file or a malicious website, a hacker could trigger the flaw and use it to jump into the kernel, or core of OS X.

Once there, the hacker would have root access, which means they could do anything they want with the computer, from installing programs to reading any files and more. Unlike other recent flaws that rely on a lot of user interaction, this one could be exploited with a simple phishing email.

To make sure your computer doesn't have this flaw, click the Apple in the upper-left corner and choose "Software Update." Or you can open the App Store app and click the Updates icon to see what's available.

As we've seen several times this year, Macs aren't immune to viruses and other security threats. That's why, just like Windows, you need security software to help you protect your system.
