Re: Warning : WINDOWS sample NOT representative
"TL:DR version: using your statistics (minus the creative bit) it appears that OSX has LESS THAN A THIRD of the exposures of Windows since 1999."
And that from nearly 1/10th of the user base. I'm afraid that your stats basically prove Grikath right; 1/4 of the Mac OS exposures are from the last year alone. OSX has actually improved in security in that time period, and yet is under far, far, far more attacks than previously. So either Mac OS has been getting exponentially more insecure since 1999, or using absolute exposure numbers is a preposterous exercise (for both you and the commentard you're disputing).
Mac security is a myth. If it's not a myth, then the stats show Apple are rapidly making it one.
