Most people not familiar with IT (and even some who are!) think that Apple's, and more specifically, Mac OS X are impenetrable, Terminator-like machines. But, they are not. Not only can spyware and malware attach to your browser, and not through an executable, but now there's news of a newly discovered malware threat that targets Mac OS X systems.
It comes in the pirated copies of image editing software "Graphic Converter". The malware is known by DevilRobber or Miner-D, and attempts to steal personal information and uses your machine's GPU to generate Bitcoins. If you didn't know what Bitcoins were, they are a digital currency that can be exchanged by online by users without the need for an intermediary bank or payment service.
