Hi people, I'm currently waiting for my first time ever macbook pro. I was wondering tough about a few things regarding the mac osx: Do I need to install an antivirus? I know its supposed to be a lot more secure than windows but my logic says that hackers will know most of the people think this way and will leave they're computers defense less. On the other, antivirus's are performance hogs. Does osx slows down over time when installing a lot of apps like in windows? amm... thats all I can think of now.. thanks for any help.
