i am a mac n windows user .
however , i am quite not understand why apple advertise that their OS X is safe from viruses .
is it due to the platform ?

i know ppl will say that viruses in .exe only works in windows . but i am sure that there is .dmg creator to damage mac OS .

i know ppl will say in the future if many ppl uses mac , there will be many virus already .

my understanding is , in this 22 years , why is there no one create virus to attack OS X officially ?

One of the biggest reasons is because of the Windows popularity.

Why create a virus for 5%* of the computer users population when there are 90%* of them to attack?

* Just my guess

and windows have so many security hole. easy to create virus.
just for info, mac os based on Unix.

I dun think so this is the main point u see. If i were the one to creat a .dmg file to make a mac OS infected by Virus, i am sure i will be famous with headlight of MAC BEING INFECTED BY VIRUS or MAC IS NO LONGER SAFE or FIRST VIRUS OUTBREAK FOR MAC etc etc. I am sure i will be famous la as the creator..

but i too wonder why none??

y?
coz windows more popular
if i make the virus y i shld aiming on mac user than windows??

maybe this can consider as one of the factors
even atm machine se windows..

If u r a virus creator . dont tell me you dowan to create a virus to play with those computer which doesnt come with a single antivirus ? for 22 years ?

seriously, if i were to be so mean to create virus, i'd target the OS that's most easy to breach and has the largest # of userbase, preferably stupid users.......people who download every single cute thing without giving a thought of where is it from and what danger it could have.

why Windows?
1. easier to attack
2. easier to spread

and MAC is not without virus either. just that it being Unix based, it's not as easy to attack it compared to Windows. then even if you attack it, how do you spread from there?
