Does turning off your MacBook by holding the power button hurt your MacBook

Almost whenever I exit out of War Craft 3: The Frozen Throne my Mac Book freezes up, as a result I frequently turn off my Mac Book by holding down the power button- Does this hurt my Mac Book?

There is most definitely a chance that you can cause stability problems (although, it is somewhat less likely that you would cause any harm to the hardware). The likelihood of you causing problems increases directly with how often you shut down this way. You should be seeking a solution to the issue you are having with WC3. As Johathan mentioned, OS X does quite a bit in it's shutdown process. Bypassing that can cause anything from basic data corruption, to stability issues, to a non-bootable system depending on what the machine is in the middle of doing when you force it to shut down. In general, worst case scenario is that you would need to re-install OS X to fix things up. It's really not worth taking a chance on your systems stability for the sake of a game. I would say that you really should try to track down a solution to the problem you are having with the game.

HT201150 How can I turn off this "feature" and have the power button bring me the shut down / restart / sleep dialog by default again?

How can I turn off this "feature" and have the power button bring me the shut down / restart / sleep dialog by default again?
With the position of the power button on the Retina MacBooks, any mistake turns off the screen in the middle of a presentation or any activity using a projector or big screen — a huge waste of time to wake up the display, enter password, have the projector sync back, watch audience disconnecting from what was being discussed, etc.
This is very annoying, and seems to add to the increasing collection of options Apple decided to make by itself instead of allowing the user to choose.
Come on Apple guys, I'm using my Mac because I want options and lots of preferences to tweak to my needs.
If I needed the lobotomized version I'd be using my iPad!
Any way (official or hack) to change this button back to its proper funcionality?
Thanks!

Not what you want, but you can get the shut down / restart / sleep dialog by holding the power button

I am trying to get my Dad's computer to turn on. It's a 17" IMac that was bought around 2007. Today it just won't turn on. When u hold the power button down, the white light comes on in the lower right hand of the computer but screen stays dark.

It have tried pulling cord out if the computer and then plugging it back ...it still won't turn on. Pls help...next step

Try using the resetting SMC procedure
http://support.apple.com/kb/HT3964
You may have done something similar already, but do it precisely as described. You should disconnect ALL peripheral devices, except for Apple keyboard and mouse.
Also, when you plug it back in, if the iMac is currently plugged into an old (or overcrowded) power strip (surge suppressor), try connecting it directly to a wall outlet by itself.

Restart your computer by holding the power......

This morning i was fooling around with a /usr/local file, i accidently deleted it and the computer stopped responding, so i held the power button for a few seconds and the computer turned off.

Nothing, the same box appeared again, Kept trying and trying..
Please help me identify the problem and solution. Thanks

Macbook stuck on blue screen and cant turn it off even by holding the power button.

Bought a refurbished macbook and it arrived today. was enjoying it for a while then i decided to reboot to get the new OS. I came back to it a minute later and there was a blue screen with the loader on it. Its been in this state for hours now and i cant reboot by holding the power button so i have no idea how to actually do anything. At the moment im leaving it running in its current state hoping it will all be sorted once the battery has run out. ANY help appreciated as i cant find anything whatsoever in forums that has any relation to my problem!!!

I pod touch 5th generation was working fine (Not sure what the last ios i downloaded was it should be ios 8 or higher). The battery died so i charged it. Now that it is charged when i hold the power button the screen turns dark blue as if it's powering on and the apple logo is about to appear but it never does nor do any other type of images on the screen. If i hold the home button Siri will say "Siri is not available please connect to internet" but there is still no image on the screen. I've tried holding down the home and power button it restart it but doing this just gave me the same results. How do i fix this problem? What's wrong with my i pod?

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.

Macbook pro 2010 only will turn on if i hold the power button down for atleast 7 seconds.....before i could just press it and it would come right on

macbook pro 2010 only will turn on if i hold the power button down for atleast 7 seconds.....before i could just press it and it would come right on

I tried those already, did not work.
I did how ever remove the command key and wiped it down and it turns on perfectly!
but now the keyboard keys seem to be out of place or something. For example it makes a "ping" sound when i hit some of them, when i hit function or control it puts the letter Z.
Any input would be great!

Everytime I start up my Mac mini I'll be able to use it only for a little while then the beach ball appears and it won't let me do anything I have to keep forcing it to turn off by holding the power button can someone help me?

Macbook wont powerup, beeps repeatedly when power button is pressed and you need to hold the power button down to shut the beeping off. any thoughts?

Have a 13" macbook. wont power up. upon hitting power button, the computer sounds 3 long beeps constantly until you hold the power button down for 5-10 seconds. any thoughts out there?

Thanks guys, i just read a few articles regarding this. i pulled all the ram and tried swapping and reseating ram. it appears both chipsets are fine but one ram slot is bad. computer will boot with either chipset installed in the one good slot but neither chipset will boot in the other slot. bummer....

My MacBook Pro 13in Mid-2010 won't start unless I hold the power button for about 10 seconds! Help Please!

Hello.
I have a MacBook Pro 13-inch (mid-2010):
Processor: 2.66GHz Intel Core 2 Duo
Memory: 4GB 1067 Mhz DDR3
Running Mac OS X 10.7.2
Yesterday I opened my computer (was sleeping as usual) and the screen just flasehed white and the computer powered off. The magnetic electricity thingy was connected and was green, so it was fully charged, and connected to the electricity.
Since it powered off, I tried turning it on again, and again, one second after starting to boot up, screen flashed white and the computer powered off.
I read somewhere I should hold down the power button longer, so I did, and it booted up. That's why I am able to write this. But every time I turn it off or put it to sleep, it does the same thing when I boot up.
If I don't hold the power button for 10 seconds or so, the computer won't work.
Then today, I did a backup of my entie hard drive, just in case. Later, I started using Excel, and about 1 hour after I was on it, suddenly it got really slow. Like I would click on a program like Safari, and it would take over 30-45 secs to start and be ready. And my computer is usually really fast!
I went on the Internet again, started in safe mode, boot up with option+command+P+R to reset PRAM, and nothing worked. Then suddenly on one turn-off/turn-on (since I can't restart because the computer only starts if I hold the power button for 10 seconds), again it is working at normal speed.
What can this be? Any ideas?
I really appreciate your time and help in advance
Gaby

I forgot to say I had already tried that as well. Just in case, I just tried it again and there was no change :S
Are you running the Apple-supplied RAM? Have you run Apple Hardware Test? I don't know what else you've tried, but this may be time to do a fresh install of Lion if you have not done so since installing Lion.

Does turning off your MacBook by holding the power button hurt your MacBook
