A) because nobody cares about putting viruses or hacking into other peoples macs, 1. theres nothing valuable on them and 2. not nearly as many people have them as the amount that have PC's, and PC's have a lot more non-computer friendly people so its easier to put viruses and shit on those kinds of people

B) PC's and macs are the same in this department, if you dont know how to run your computer then its gonna run shitty, but if you know what you're doing and dont clog it up then it'll run smoothly
