I think this is complete FUD to be honest. There is a war on the market due to economic incentives. There are some criminals, but they don't target your workstation specifically.

Previously a hacker might have gotten access to your computer and maybe you had a keylogger, which could compromise you to a great deal. Today you have so much of your info not on your local device that you have countless additional attack vectors. Where do peoples info get leaked? In cloud services mostly.

edit: And of course your info is not safe. The programs you run get send to Apple. That is nothing else as a data leak.
