Holding Down Power to shut down Macbook
My Macbook recently wouldn't shut down it just showed the background image on screen but no shut down. So I had to hold the power button for about 8 seconds to shut the computer down. Just curious does that damage the computer in any way or is it safe when necessary? New Mac convert.
No it will not do any physical hard drive damage or any hardware damage.
Do you notice that when you shut down your computer it stays on the background image with a rotating gear that is very faint? You probably did not notice that and thought it was stuck. It is not stuck and will shut down after a minute or so. It is doing necessary maintenance on the drive that should NOT be interrupted. Interrupting that sequence many times will result in a corrupted OS.
As long as you wait 15 seconds for the HD to spin down after holding the power button you will not cause any damage. Of course you don't want to take this as your normal way of shutting down to replace the Apple Menu, Shutdown Option.
Hope this helps,

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.

Why can't I shut down my MacBook unless I hold down the power key?
Hi all,
I have had this problem my MacBook Pro using both Leopard and Jaguar. It is a problem when I shut down using either the drop down menu or by the power key menu. It appears to shut down but when I close the lid the "sleep" light comes on and is steady. It isn't actually shutting down because if I don't have the power charger plugged in it will run out of charge.
So, to shut down, I hold the power key down for about 10 seconds.
If it does fall asleep I am unable to awaken it (the sleep light is steady) and have to go through the holding down the power key procedure to shut it down and then use the power key to start it back up.
Am I damaging it by doing this? I have tried the trouble shooting options as described in the manual. I had this problem before and one day it just wouldn't turn on and I had the hard drive replaced.
Thank-you very much for any help!

State: EnabledI have found a solution on another thread that seems to have solved the problem for me. That is, I haven't experienced since, either the double password prompt at wake from sleep or the issue of not being able to shutdown.
The solution requires deleting a preference file that apparently carried over from Tiger in the upgrade to Leopard and which is causing all the problems described. Preference files or .plist files hold configuration preferences and settings generally defined by the user for a particular operating system function. Deleting one of these files will result in the system recreating it on reboot with all settings set to default values, this is a simple way of fixing an incompatible/corrupt preference file.

Macbook pro wont shut down without holding the power button nor cycle for updates to restart.
macbook pro wont shut down without holding the power button nor cycle for updates to restart
Sorry I said sorta wrong. I can shut down and I can update to the point of restart but it just sat for 45 minutes after an update. It goes through the update and to restart then the bars chase each other in a circle and it never restarts. So I hit the power button and go through normal reboot but loosing the update in the process. It does not matter how long I wait for a natural reboot after an update or click to restart it will chase the little bar in circles all day literally and never reboot.

New macbook pro freezes intermittently, need to hold power to shut down
i just got a new macbook pro in june. i have 8 GB ram, a 1 TB hard drive.
it constantly freezes and i cant do anything except shut down my computer by holding the power button
last time it happened i had just finished downloading mountain lion, i was watching a youtube video, and the mountain lion installer seemed to try to boot up. here is the panic report or whatever.
can anyone confirm whether this is fixable on my end or should i just take it in to apple?? i am assuming they will cover it since it has nothing to do with me and i just bought the computer.

While transferring files from one external hard drive to another, my MacBook Pro routinely would freeze and often render a message to hold down the start button until it shut down and then restart. I have i7 why does it keep locking up?
You can go back to original hardware; run Apple Hardware Test even.
Remove 3rd party RAM ( much rarer I think )
USB printers, cables, devices and drivers.
What changed?
Also, this is not MBP forum.

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....

Macbook Pro is slow, freezes constantly and I'm forced to hold down the power button to turn it off.
Hey all,
This is my first post/discussion so hopefully I'm posting in the right section and all. Anyway, as of recently (few days) my Macbook Pro 15" (model previous to the one just released) has been been slow + lagging, also when this happens my computer freezes, but its kind of different: I can still move the cursor around and stuff, but for instance, if its google chrome that freezes I won't be able to close it, (tried force quit), after this, my whole computer kinda freezes and I can't close any of my programs, I can't click on the menu's at the top to shut down or doing anything really, eg. change internet connections. Closing my macbook, like shutting the lid doesn't solve anything, only turning it off by holding the power button for a few seconds, which I'm almost certain isn't a good thing. I've had to do this like 3 times today and its getting pretty frustrating.
Something tells me that it might be because of memory usage, but I'm not entirely sure, I only say this because when looking at the available/free memory using iStat sometimes, its really low, like 12mb, 30mb, etc.
Anyway, I know that's quite a lot of infomration but hopefully its useful, if there's any additional information you require that may be of help to you, please tell me and I'll do my best to provide it.
Thanks,
Roshen.Roshen,
There are a couple of things you can try, but it sounds to me as if it's a problem with your hard drive.
First, open Activity Monitor in your Utilities folder and see how much of your CPU % is being used by any one application (you can sort by %). If any one application/process is taking up more than 15% or so of your CPU, try killing (quitting) the process.
Second, since yours is a 2011 model, it will have come with Lion installed. Shut down your machine and boot up while holding down the Command and R keys. Open Disk Utility and verify your disk. If it comes up with errors, click repair.
If neither of these work, take your MBP into your local Apple Store. You should still be under warranty, even if you didn't purchase AppleCare. All beforehand and make an appointment.
Good luck,
Clinton -
purchased Lion, installed it - once I log in - i get the curtain and message to hold the power button till it shuts down. Worked with the disk repair utility - fixed permissions to hold the power button till it shuts down. Worked with the disk repair utility - fixed permissions - still can't get past the "black curtain of death" any suggestions?
My machine was patched to date 10.x.x. I was lucky to get an internet connection and I selected the option to re-download Lion... its curruently being downloaded. What if that doesn't work?
Any thougths would be appreciated.
JoeAnd you have a workstation? not a notebook.
Usually a driver or hardware, nothing that Disk utility will fix.

My macbook pro (August 2010) keeps freezing when apple mail starts up. This happens every 2nd time I turn on my Macbook Pro. This forces me to hold down the power button to restart my Macbook Pro. Does anyone else experience this, and is there a fix? Thx.
since upgrading to OS lion, my mac book pro (2010 August) keeps freezing (non responsive, requires restart) when i turn on my mac and the system is trying to open apple mail. while apple mail is attempting to collect new mail, the macbook pro freezes. this happens every 2nd time i try to start up my computer. this only started happening after i upgraded to OS lion. please let me know what I need to do to fix this. being forced to restart every 2nd time i turn on my macbook pro has been very frustrating. not sure if apple mail is also the cause of my macbook pro for being very slow during start-up (on the occasion the computer doesn't freeze).I am having similar 'freezing' problems with many programs (Mail, Safari, iTunes, etc.). I have done a clean install of Lion instead of an upgrade when it came out. Perhaps something went wrong with my install? I'm thinking about wiping and reinstalling.

I was listening to a YouTube video on the history of X15 rocket airplanes. All of sudden, out of the blue a translucent back message drops top down, stops the video, locks up my MacBook Pro screen and demands that I restart my lapTop by first holding down my power switch, then turn the lapTop back on. This has never happened to me before. The message was in black & white, and in about 6 languages: English, French, Spanish, Dutch, Japanese, Chinese. Does any one recognize what this might be?
The Computer turned back on just fine as if nothing had Now I am freeking out that they could be reading my key strokes or something. Could they have used this tactic to install malicious software on my computer by first taking away my ability to do anything about it being that I am not a software engineer? Can any one think of anything simillar? I reported this as a bug to APPLE the regular way, then cleared my Safari cookies, then run software update which returned nothing new as in " your software is up to date at this time."
Can any one please help?

Thank you so much. This seems to make sense to me now. I was freaking out a bit that some hacker could be messing with my MacBook Pro. I will be monitoring this issue from now on as it has never happened before.

I just installed OS X Yosemite on my MacBook. I now cannot get the computer to start up. If I hold down the power button to try and power it back up, it will not start. Any ideas on how to fix this?
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Download and install the OS X Yosemite 10.10.3 Combo Update.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:
Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X

My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. I have tried several times to get it past this point but tnothing helped.
I have an appointment at the Apple store today, but was wondering : will all of the information and files on my desktop be lost? Or is this a logic board problem?
Any help is much MUCH appricated.I'm not sure, if you're out of warrenty it'll cost quite a bit for the replacement of the logic board replacement...unless you have apple care. you could ask apple to try and recover your hard drive but i'm not sure.

I'm getting kernel panics each day as I shut down, the message of restarting by holding down the power button appears on the screen - it began about a month ago and. Do you have any ideas of how to solve the problem? I've copied the logs that I found for each kernel panic that still have the message logged. Please help if you can, I have read some of the other comments and perhaps it has something to do with my anti-virus software being on at start up. I have copied the log here. Any advice will be welcome.

Two experiments you can try.
1. Boot in safe mode and see if you can shut down normally. All thise additions won't be running in safe mode so this test would indicate it is one of them causing the problem.
2. Uninstall all the intego VirusBarrier stuff. That's my first guess and the troublemaker. -
when i click on my external hard drive the screen goes dark and a msg pops up saying i have to shut down my computer by holding the power button and then restart it. when i do that i get the same result every time. it worked perfectly last night..
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Ifou don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
