Well,, Mac had a very long going (maybe still?) really bad bug that could/would allow unknown users to access the PC with full root (admin) access. They tried to keep it hush. You can look it up.
Windows also runs on 98% more hardware, and supports 99% more software,
Mac is limited to what they decide to support (2%) if that?.
So, yeah,, I would say that 1,, is a HUGE deal. And Mac community can ,, blankity, blank, my ass.
I would have to say that Linux is hacked quite often when someone breaks into a server, But the difference is the majority of times Linux is successfully hacked can be attributed to the System admin not taking proper security precautions. not because of a flaw in the system.
