Multiple responses to multiple mistakes
I prefer to think that they aren't deliberate falsehoods:
@Neil: "The only reason Mac's are more secure is because no one can be bothered to make viruses for them when it is not a dominant product."
False. There was a time when the Mac OS was *the* dominant OS in schools and universities, and the fact is that Macs have always been less prone to malicious software because the OS design was always more secure than anything Microsoft had. Sure, there were a lot of viruses aimed at "old-school_ Mac OS - but the primary method of distribtuion was via floppy disk. That's infinitely slower than the Internet. Furthermore, OSX is based on Linux, and Linux is secure-by-design (as opposed to "sort-of secure by third-party, crash-prone, and buffer-overflow-ridden add-on products" which described Windows to a "T").
@Wade Burchette: "Macs use security through obscurity."
False. Mac OSX uses security-by-design, as all versions of Linux should do (Lindows is a glaring exception, having been configured to run as "root," which is precisely what you should *never* do - and is precisely what all versions of Windows have doone, up until Vista).
@axx: "So bearing in mind that the major banks, retailers and credit card companies that spend millions on security still get hacked all the time, why is it that a large proportion of Apple Mac users incorrectly remain under the impression that the OSX operating system is hack proof?"
Are you under the impression that banks are running Macs? Or that they aren't suffering from the usual weakest link - the "social engineering" attack? I can attest that the majority of the problems are cause by bank employees (who, by the way, *are* using Windows) stupidly giving out access information that should have been kept confidential, and the rest by Web hacks (usually on Windows IIS servers, by the way - when the server is not running Windows, then the hack is *always* an older and well-known vulnerability, which should have been patched, for which patches were available, and which the bank's IT Department failed to patch).
Re: Hardware Differences: "If Microsoft could release their own PC with all their own hardware and their own drivers it would be a completely different matter."
MS did just that. It's called the "Xbox." And what does it do? Why, it plays games. It excels at playing games, in fact. But the operating system is burned into a ROM chip - guess how hard it is to infect a ROM chip. Go on, I'll give you three guesses! So, even Microsoft knows that a "secure" Windows PC needs two things: (1) major limitations on what software it can use; and (2) Windows must be permanently installed in such a way that it can't be modified without hacking the hardware.
And for the record - I don't own a Mac, don't especially want a Mac, and I make my living maintaining Windows PCs (and I make a nice side bit of dosh cleaning up infected Windows PCs). I do have several Linux PCs, and five Windows PCs (one Win2K, four WinXP, and one of those will dual-boot Vista as soon as I ahve time to install the beast). My job involves a lot of security work and security awareness - and my job would be orders of magnitude less work if my employer used Mac OSX on the desktop - but the same is true if he used Linux, and that's essentially free (installation still costs some time, and time is money so...). I rather like Windows XP, within certain limitations; it's excellent for playing games, after all. But it's *not* secure, and neither it nor Vista will ever *be* secure as long as Microsoft continues to support things such as Browser Helper Objects, Web browsers that are integrated into the OS, silent privilege elevation, and pushing for "bells and whistles" in the GUI at the expense of security in the kernel.
