Been using Macs since the early 80’s, for our small business and personal use - never have had a virus - and neither have any of my adult children who use Macs.
Never needed IT for help either.
You apparently do not know what you don’t know!
My guess is that you have no personal experience with Macs, but desperately want what you think you know to be true.
More’s the pity.
A simple iMac could solve so many problems for so little money.
I own a computer software company. One service we offer is pen testing. An anecdote is not the same as reality. Google “Mac virus 2014” and get back to me.
I, too, have been a Mac user from the beginning. Never had a single issue of of a virus intrusion.
Never had a need to defrag or have virus protection software installed either.
My new iPhone 6+ and MacBook Pro retina 16g memory (2011) work as they are supposed to, with ease, capability and simplicity — oh, and they’re also fast!
