Versus being one of a gazillion on Windows and being lost in the shuffle
I'm not buying the argument. What does a hacker gain by writing a virus? Data? Not unless it was written for a specific purpose. Satisfaction of bringing down a company that they have probably never heard of? Hmmm, not really. Notoriety in the hacker community? I find this more likely. Hackers get ZERO return on their virus other than the thrill.
Would I rather be one of many to write a virus that affects Windows and people go ho hum... another virus, run your updates.
Or would I rather hit the news world by being the ONLY one to bring the arrogant, uppity Mac world down by being the first and ONLY one to crack what the snooty Mac users claim is invincible?
Quick, name the last 5 major Windows viruses and the affect they had on the Corporate world without Googling for results.
Now, imagine a virus that devastated the Mac community because there was no AV on any machines and it replicated like wildfire before anyone could write a solution. People would remember that.
The market-share argument isn't totally irrelevant, but it is not the primary reason for no viruses on the Mac. That is due to the Unix base and the stability of the OS. Is it perfect? No. Does it have vulnerabilities? Yes. Have they been exploited? No.
If all this was true then WHY has NO-ONE bothered to write a Mac virus?
Devastating the Mac community would only have an effect on the Mac community a devastating windows virus can do a lot more harm purely because it has more chance to affect vital systems. You will NOT see a Mac being used in such mission-critical ways.
If someone were so inclined I`m quite sure they could write a virus that would install invisibly even on Unix/OSX, the fact is that apparently no-one has so far felt inclined to do it.
Market-share is not the only reason but I`m damn sure its the main reason, that and the potential to cause chaos, if a few Macs crash then the world simply won`t notice.
Hell, at this point, if the Mac ceased to exist tomorrow the only people who would really notice are Mac users.
The sad fact is that if Windows ceased to exist tomorrow, the modern world would quickly stop functioning.
