Macbook won't reboot

After running some updates and restarting my macbook, it will no longer fully reboot. It'll get to the Apple logo and spinning image and stop there for a few minutes. Then it will restart by itself and start the process over again. I've tried some things that has been listed on Apple Support page, like flushing the PRAM. Nothing works.
My drive is partitioned and the part that holds my programs and boots up the computer is nearly full so I am thinking it may be an issue with lack of space. Is there a way to free up enough space so I can boot up the computer?

All right I won't mention a PRAM reset....
Since you haven't stated exactly what you have tried I will suggest booting from your install DVD 1...
Insert the DVD1 into the disk drive and hold down the 'C' key while restarting...
after you select your language...like you were going to reinstall the OS (but don't) go to the menu bar at the top of the screen and select 'Disk Utility' and from there choose your 'MacIntosh HD' from the left column and then the 'First Aid' tab and 'Repair Disk'...
Also you might try holding down the 'Shift' key to boot into 'Safe Mode'....see if it will boot there...
This link speaks of several things to look at to free up some drive space..

Help: Macbook won't reboot, can't reinstall OS

My MacBook hung in Quark Xpress 7.01; could't force quit, had to shut down by holding down power key. Since when MacBook has failed to revive. It won't restart on its own. Installer Disk 1 Repair Utility fails to find the hard disk to repair; it cannot find hard disk on which to install OS; hardware test using extended testing shows no hardware fault; any thoughts?
Dave

try to restart while pressing "option" key, and when it started, see if the screen shows 2 option (OS from HD and OS from disk).
If there is only one shows (OS from disk), maybe you have a faulty HD.
Try to reset PMU and see how it goes, and if that still fail, try to reseat the HD.

and click on upgrade the HD, but you just re-seated that not replacing it.
Good Luck.

2006 Macbook won't reboot after losing power during update:

My older Macbook lost power during software update (battery is dead and only works while plugged in to outlet) and now will not reboot. I get the apple screen with the spinning wheel of doom. Please help! My 5 year old son is very upset that he messed up mommy's computer.

Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU 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 DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Macbook won't reboot after updates

Hi, I did a round of updates last night through the software update feature.
The MacBook seemed to almost finish installing. The bar was 95% across.
But never finished. I let it go over night. This morning screen saver was on.
Machine could not be woken up. I held power button in for a bit to shut down.
Tried to boot up machine. Gets to the gray screen but just spins. Never boots up.
The MacBook is a Black Plastic one from March 2007.
10.7 2 GB RAM. 160 GB HD.
Any ideas ?
Thanks

She bought the computer used so unfortunately she does not have the start up disk. She also has not backed up the information on the computer but we are more concerned about getting the computer to work because she cannot afford to buy a new one and she has barely had this one more than a year. The only thing that is connected to the computer is the power cord and the battery is shot so we cannot disconnect the power cord and use the computer. Well I read the instructions on starting up in safe mode so I hold the power button until I hear the obnoxious beep and then hold the shift key down until u see the little gear thing and apple logo. Well I get the apple logo but no gear and then I get the pop up window that I spoke of before telling
Me to restart and there is the lines of "code" in the back ground.

MacBook won't reboot after SMC update

ok here's a weird one, anyone else have this problem? ran the SMC update on the MacBook, machine shut down like it's supposed to, but never restarted. if you attempt to restart it the machine just freezes at the blue screen.
machine is plugged into AC power.
SMU reset.
battery removed.
any ideas?

Ill explain in detail what my therory is with the blue screen. The problem is 10.4.7 messed up how pram settings are saved on some macbooks and the pram also saves what system folder the computer loads by default and when the computer PRAM isent saved right the computer wont know what system folder to load thats why you get a weird blue screen when you try to boot, this is why zapping the pram will let you start up
another clue its a software issue is because the start up chime comes on which means the software has started to load and seeing as how the blue screen happens after the chime it must be a software issue, if it were to show up without the chime (like the colored vertical lines did in some macbooks my last one included) then it would most likely be a hardware issue
and also i called and talked to a MacBook product specialist for about an hour and he to came to the conclusion this was a software issue

MacBook won't reboot after Kernel Panic!

Hi everyone! Been reading these boards for a while and it turns out now I need help.
I was simply browsing the internet (Safari 3) earlier when my one year old MacBook suddenly stopped working with a Kernel Panic. At the time of the crash I had my external USB drive and a USB-MIDI interface connected, both of which have never caused me any problems whatsoever.
I switched off my external HD and restarted my Mac, thinking this was just an exceptional error. Unfortunately, upon restart, my MacBook gave me the following error message:
panic(cpu 0 caller 0x003ABD33): Unable to find driver for this platform 'ACPI'.
And then went into Kernel Panic
I then decided to try and boot off my OSX startup disk. Thing is, I can't even get to this screen anymore. Subsequent restarts result in a black screen and the sleep light being lit, but nothing else seems to be working. The disk drive makes a short 'eject' noise which is usually followed by the boot sequence but it's as though the whole machine just freezes after making the sound. Sometimes it will go into some sort of loop and repeat the eject noise until I kill the power.
My MacBook (white) is just 13 months old (out of warranty), 2.16 Ghz C2D, 2 GB RAM. Running OSX 10.4.11 with all updates. Never had a problem with it until today. It's been looked after well and has had regular disk checks, permission repairs and running of maintenance scripts.
Any help would be most appreciated.

I have already tried unplugging everything, the problem is that I cannot even get to the startup process. The screen doesn't even turn gray, so I can't even boot up in safe mode.

MacBook Pro won't reboot. Get spinning circle even after hard drive replaced at Apple Store

MacBook Pro won't reboot. Have to reinstall OSX each time I shut down in order to get it to start up. What could be wrong? I had the hard drive replaced already.

You shouldn't be using the disc at all. I thought I had made that clear. Boot from your recovery partition and run Disc Utility. If you get the same result -- the internal drive can't be repaired -- then you should consider replacing it. No storage device can be trusted, in my opinion, after throwing an error like that. But whether you choose to replace it or erase it, you have to get the data out first.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

After installing Maverick on my Macbook it won't reboot

Macbook pro won't reboot after installing lion

After installing Lion on a 2007 MacBook pro, it won't reboot. Just gets to the gray screen with the spinning wheel. Have tried re-installing and disk repair to no avail. Anyone else figured out how to fix?

Lion only runs on Intel based systems which have to be core2duo. with a minimum of 2GB RAM.
If these is given on your system, in most cases it comes from running old PPC-Applications which are not longer supported since Lion.
Try to start your MB in "Safe Mode" by holding option key (alt) imediately after first chime and disable / delete this applications.

MacBook Pro won't reboot after Lion update

I have updated my new MacBook Pro (2.3GHz I7 15"), and everything seemed to be working fine. Something was chugging away at the system resources when I was away from my computer and when I came back, I decided to reboot the system.
Now all that will happen is boot up to the Apple logo and spin the little grey circle, for an hour! I don't know what to do, help my computer is useless!
I have booted into the recovery partition and repaired permissions, but it did not help. Anyone have any ideas?

Just downloaded new IOS 8.2 on MacBook Pro shutdown ready to restart & it won't reboot up HELP PLEASE...???

Hi Ive just downloaded the new IOS 8.2 on my MacBook Pro, it tells you to shutdown now, to finish installing - which Ive done. Went to boot it up again and all it dose is show me the apple sign and lots of black letters numbers and the odd word something about the 64bit is missing - Im doing my Criminology Honours Degree & doing a PowerPoint lecture - or should I say was!!!! And now my macbook won't turn on.... HELP PLEASE??????

use a torx screwdriver and open the back casing, from there you can proceed to get your hard drive out. then you can retrieve the data using a universal hard drive to usb adapter (you can find them cheap on amazon).
and if you are desperate to get it to turn on you can use the power on pads: from there we can see what is going on. (this is NOT a technique for every day use)

MacBook won't automatically sleep

My MacBook won't automatically sleep anymore. If I close the lid or command it to sleep, it will. But it will no longer automatically sleep. I've tried tons of fixes and searched for hours on the internet, but still have not found a solution. I seem to have noticed that this starting happening after I installed Windows XP via Bootcamp, so I'm guessing that the problem is related to that. Any ideas?

This is for a Mac that won't sleep.
Here is KB article HT1776 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB card.
Also, here is Apple KB article TA2469 about PCI cards and sleep.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Tristan Currier noticed this; "I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps.
Check the printer queue!"
Allan Jones says "sometimes there is Network activity: launch System Preferences > Energy Saver > "Options" tab and uncheck "Wake for Ethernet network administrator access."
Good Luck!  DALE

MacBook won't boot - Error: The underlying task reported failure on exit

My wife's new MacBook won't start up. It crashed earlier today and when she tried to restart it, it got as far as the gray Apple logo and the spinning gear and then it reboots again. I booted it with the Leopard install disc and two strange things happened.
1. When the installer first opens, it gives me an error that says I cannot install Mac OS X on this computer. This is a 3 month old MacBook that shipped with Leopard, but it's telling me that OS X can't be installed.
2. When I run verify or repair permissions with Disk Utility from the Leopard disc, I almost immediately get an error stating "The underlying task reported failure on exit". When I try to verify or repair the disk, it says everything is fine.
The HD appears to be fine. I can access it from Firewire Target Disk Mode and everything is still there. I can also boot into Single User Mode, but not Safe Mode.
The night before the crash I made a change to the HD permissions via "Get Info". I copied the "Read/Write" settings to all enclosed folders because it was telling me that it couldn't install Flashplayer because I didn't have sufficient permission, even though she has an Admin account. After the change, Flashplayer installed just fine and everything was OK until this afternoon when she had a kernel panic while iChatting. iChat was the only program open at the time. She rebooted and hasn't gotten past the gray Apple logo since. I read in some other threads about people having the same issue after accidently setting HD permissions to "none". One suggestion was to use Firewire Target Disk Mode to open the drive with another computer and change the permissions back. I tried that, and the drive opened just fine, as I mentioned, but the permissions didn't appear to be set in a way that would cause problems. I set all of them to read/write and applied them to all enclosed folders just to be sure, but nothing changed when I rebooted.
Any other suggestions will be much appreciated. Thanks!

Everyone: Read Only
This is not your problem unless you have changed the r/w for special accounts elsewhere.
I have the same on my HD. But it's the individual files that are important.
Nothing there indicates that it should be locking her account out.
How do you create a new admin account from the Leopard DVD? It wouldn't allow me to do much of anything except Disk Utility.
I have not done it so I don't know, but there is a way to create a new administrator account using the DVD. Search these forums because I know others have done it.
Would it be possible to attempt to change things back by booting into single user mode? If so, what do I need to do?
I am not sure you can even boot into the Single User mode, or do you mean the Super User mode?
You have taken write privs away from everyone so I believe only a Super User can fix it. I am not even sure the Sudo will work in your case.
Thanks for your help!
If you find out how to access your drive from the Leopard DVD, you need to invoke SU privileges and undo whatever it was you did.
Were you using Time Machine? That would make fixing it a piece of cake. Just revert to the last backup before you made these changes.

Macbook won't restart while updating 10.6.0 - 10.6.8

Hello all,
I'm having trouble updating my Macbook Pro 13 inch from 2009.
Yesterday I turned my Macbook Pro on for the first time in 2 years and I want to bring some life in it.
It still had the version 10.5.8 which I updated with a usb to 10.6.
Now I want to update my OS X version from 10.6.0 to 10.6.8. I've downloaded the files by clicking on ''software update'' through ''about my mac''.
It now asks for a reboot, so it will install the updates. However, the macbook won't restart.
I click on restart and all it does is show very short a blue screen and then I see my background with only my mouse cursor which I can still move around. All of the applications and toolbars are gone and I can wait an hour and it will still be in the same position. So I have to force the shutdown by holding the power button... And when I turn it back on, it didn't install anything.
Can someone please help me out?
Kind regards!
