Short answer: It doesn't hurt anything.
If someone knows your media access control (MAC) address, there's not much malicious they can do. And anything that could be done would have to occur on the same network segment, i.e. from people physically close to you on the network.
At worst, someone could "spoof" your MAC address and make it look like you are doing things on the network that you aren't. They could also use that same technique to direct a ton of traffic to your machine that could make network communications difficult (called a denial of service or DoS attack), but again, they'd have to be local to your network.
You can change your MAC address on most machines/operating systems. Most users wouldn't have a need to do that. But the MAC address that's usually used is the one that's physically burned into the chips on the network interface card (NIC). And the silly thing is, even if you did change it in software, someone could quickly and easily listen to the broadcast of it to find the new (changed) address again.
What else can I help you with?
Can you hack computer by using MAC address?
The Answer is Yes And No Both, Yes Because They can hack and no Because There is a Authentication Required for that ------- The MAC (Media Adapter Address) address is only a hardware identifier. There is no intelligence to hack. It can only be used to uniquely identify a specific network component.
Is it possible to hack into a Mac computer?
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.
What harm can it be by showing your Mac address?
There's no really much harm in actually showing someone your MAC Address. All i make MAC Address is a 12 digital and letter code that identifies the network card. If someone had your MAC Address they could try and gain access to your network. But that's all. *edit* Yeah, like what the previous person said. If someone got your MAC address and IP address, when you turn on your computer they could try to MAC spoof their way into your network by making their computer looking like your computer.

What is the drawback of using a MAC address?
Someone can spoof it using a MAC spoof attack. This is where an attack acquires your MAC address, sends a disconnect signal to your computer to disconnect you from the network, and then connects onto the network with your MAC address, making the network's authentication systems think it is you, but it is really a hacker. When you try to get back on, you find that you can't because the network won't allow two computers with the same MAC address to be connected on the network.
