For a couple of months Apple has been aware of some malware called ‘Mac Flashback’ and a resounding failure to do anything about it has cause and estimated (so far) 600,000 viral infections on Mac. Thus the arguement finally ends, and rest assured this isn’t the first virus it’s just the first that cannot be swept under the rug.
So the time has come and you’ll need to check your computer for a bug, and unlike the well versed PC market it won’t be easy. Then you’ll have to get a some real protection because what comes with the computer isn’t sufficient (obviously). Steve Jobs is dead, Mac can get viruses and solution isn’t easy or pretty; welcome to the real world.
