macs=scam

Windows has poor security compared to mac (The point all macfags will try to make) But if updated often enough, And with anti virus programs, You wont get virus's.
Macs are a candy coated idiot proof version of a PC. Those who know nothing of computers will think "Oh yay a mac, It's pretty, It cant get virus's, It's perfect for me, It's hip". Yet windows is just in general more powerful. There are a HANDFULL of things you cant do on macs that can be done on windows. And im not talking about these little stupid asthetic things like a pretty download box. Mac is for those who want to surf the web, Download music and edit pictures. Can you do too much more than that? nope. Windows has OPTIONS. Sure it might not be as safe as a mac, But you dont need safe if you're skilled.

tl;dr - Give a skilled hacker something running windows, the possibilitys are endless. Give them a mac and they cant do shit.

This thread is pretty /g/ quality.
My position on this:
Buying Macs is stupid, and like most things Apple makes, it's a very good scam.
Installing OS X is excusable. Some people like the GUI and it's still BSD-based, altough the kernel updates lag behind compared to other BSD's. Sometimes vulnerabilities go for many months unpatched.
In Windows NT you can run POSIX-compliant applications through compatibility layers, like free open-source ones, or Microsoft's own UNIX compatibility subsystem (not installed by default).

Regarding OP's claim about viruses, there are a lot of malware on Windows, because it's the most popular desktop OS. There are some malware for various *nix'es as well, but the quantity is much smaller, and they're much less spread. They can be prevented on either OS by keeping your services and clients up to date (don't get owned), and isolating the environment enough that if you do get owned, they can't do any damage (user permissions/ filesystem permissions, virtualization, chrooting, and so on). On OS X, one could take some older vulnerabilities that Apple hasn't fixed yet and exploit those, but it seems few people are interested in exploiting Mac boxes, because they're a minority and it usually isn't worth the extra effort. OS X users can enjoy the fake safety feeling one enjoys by not having a popular OS, but they'd be no more safer in a targetted attack, or maybe a OS X-only attack.

PS: "Security software" and antiviruses that OP mentioned are obviously useless and only a preventive measure against known/seen-before malware. They can't protect one from a targetted attack, or a 0-day one.
