PC means personal computer and mac means Mandatory Access Control
A Media Access Control address (MAC address) is what identifies your computer on a network. You should be able to find it within your network preferences or in a summary of the computers status.
Terminal or Console
Media Access Control (MAC) address filtering is a little different from WEP or WPA. It doesn't use a password to authenticate users - it uses a computer's physical hardware. Each computer has its own unique MAC address. MAC address filtering allows only machines with specific MAC address access the network. You must specify which addresses are allowed when you set up your router. This method is very secure, but if you buy a new computer or if visitors to your home want to use your network, you'll need to add the new machines' MAC addresses to the list of approved addresses.
It is possible to hack into a Mac. If you have physical access to the Mac then it is possible to hack into it. If you can persuade someone to download a script that will give you access to the Mac then it is possible to hack into the Mac remotely - this was the case at the recent pwn2own contest. Another answer: It is getting even easier as more people get MACs. The default for Mac computers is "accept all incoming." A program can now get into a MAC computer and take it over without the user realizing it. Anyone with a MAC should go into System Preferences and into security. You should change from the default to block all incoming. That way only programs that you send out, such as Safari can receive replies. No one can hack into your computer.
Every piece of equipment (computers, printers etc.) has a MAC (Media Access Control) address which identifies it when it is connected to a network. To spoof the MAC address is to supply the network with a different address than the one allocated for your computer so you are pretending to be another computer.
