And, btw, I can write a malware program that hits Macs or Linux. Why? Because most malware relies on a user clicking on “Sure! I want to install this!”. There is no stopping this breach.
The easiest way to get passwords for systems is to dumpster dive or get into offices after hours. Look under keyboards, in drawers, etc. where people write them down. Security if often not connected with the O/S but with people not taking precautions.
Basically, trashing Windows buys little. Linux is wide-open compared to z/OS. Those both are wide-open compared to a closed system that never connects to the net.
but but but mac has NEVER had a self propagating virus!! really it hasn’t. That must mean its secure.
