20+ years of using Macs, never installed any firewall or A/V protection of any kind and never had any problems. Isn't that why people buy macs, so they don't have to bother with all that stuff? When I open up emails on my mac that were known viruses that affected our computers at work, it just says, "Cannot find the application that created this program" and it asks me if I'd like to move it to the trash, haha.
I think Toyota owners are prob gonna be a high percentage of Mac users,
it just makes sense, if you pay more to buy a quality product like a Toyota, then you will prob pay more to buy a quality product from Apple.
