Macbook constant reboot cycle

I own a 2ghz Macbook with 2gb ram and am running Mac OS X 10.5.2.
I have performed all the latest software updates but now my Macbook is stuck in a cycle of booting, getting to the grey screen with the apple, churning for a few minutes then rebooting. It continues to do this and never reaches the OS.
I've found if I boot from the Leopard DVD, cancel the install and reboot from the menu it boots properly and as long as I sleep it, it will work correctly. But if I reboot or shutdown and start again I get stuck in the constant reboot cycle again.
Any ideas?

A.E.S.'s suggestion is definitely the first thing to try. If Disk Utility does not resolve your issue and reports no underlying disk errors or is able to repair whatever disk errors it finds, try an Archive and Install. If Disk Utility reports underlying disk errors that it's unable to repair, you'll probably have to do an Erase and Install. Also, be sure to back up all important information before doing the Erase and Install.

  • Macbook- Endless reboot cycle- Failed 10.5.2 attempt!!!!

    Hi,
    I've got a Macbook. I tried doing the 10.5.2 update and then it froze along the process, so I rebooted. The computer wouldn't get past the white screen spinning wheel Apple screen on startup, so I figured I really screwed things up. So I put in the Leopard disk and did an Archive and Install thinking that I could start anew. After that though, all my machine does is go to the white Apple spinning screen for a while before it restarts, by itself, again and again. It is an endless cycle.
    Please can someone help me. Please don't tell me what I should have done(permissions repair etc. I did that) I need some advice for what I should do from here. Thanks!
    BTW- I did a PRAM reset and I did a 'verify disk' in Disk Utility off of the installation disk. No problems were reported.

    Just an Update in case anyone else has a similar problem..
    Went to the Genius bar at the Apple store. They booted my machine using one of their external hard drives and ran the 10.5.2 COMBO Update. That did the trick and I'm back up running again. thanks Apple!!

  • Constant Reboot after software update

    I just performed Software Update on my Leopard MacBook Pro and now it's in a constant reboot cycle. The grey boot up screen displays for 90 secs or so and then reboots and the cycle repeats. There were three programs for update but the only two I remember were iTunes & Front Row. How do I recover? Thanks.
    Kevin

    Just to add some more detail to the issue:
    I've reset the NVRAM by holding down the Option/Control - PR at bootup and it seemed to work in that it then rebooted again. But nothing else but the continuing reboot cycle.
    Next I tried to get into Safe mode by holding down the Shift key on bootup but this did not work. I inserted the Leopard DVD on bootup but it just spins.
    Help!!!

  • Upgrade causes constant reboot

    Has anyone else had their iPhone go into a constant reboot cycle after the OS upgrade? I've been watching the Apple logo flash on/off for the past hour. Hard reset doesn't work. Any ideas of how to get it to boot?

    Mate it might be because the software hasnt actually become live yet, :/, You might have got a version that slipped through the server, Sometimes happens, It should fix when the full software is released, If not Go to your apple store

  • My iPad 2 is in a state of constant reboot! Help!

    My iPad 2 is currently in a state of constant reboot - cycling continually between the Apple icon and the "waiting" icon (wheel of death, as I've seen it referred to).  It cannot be interrupted, and keeps going for hours until it runs out of battery.
    I've tried the hardware reset a few times, which interrupts the cycle, and brings up the Apple icon, but then it just immediately retuns to it's previous state of constant reboot.
    I've tried connecting it to iTunes. iTunes recognises it but says I have to unlock it with my unlock key. I cannot do this because it is not possible to interrupt the reboot sequence to get the input panel.
    It is not jailbroken, and I'm happy to have it restored from scratch.
    I am in China temporarily, and my iPad has become quite a lifeline for me, and am devastated that it's stopped working.
    I can take it to the Apple Store here, but would prefer to fix this from home.  However, I also don't want to mess this up such that the Apple store folks think I've tried to Jailbreak the iPad, because that definitely is not my intention!
    Any thoughts/hints/tips?
    Thanks.

    Restore seems to be the best option. Have you tried a hard reset ?

  • 9320 on Constant Reboot after Trying to Turn On Bluetooth

    My BB Curve 9320 is constant reboot.
    I've had the phone about 9 months.  I went to turn on the Bluetooth for the first time today.  As soon as I opened the menu tray and "checked" bluetooth the phone shut off.  It started to reboot...it went through the whole cycle of loading and will reach the regular screen, but after 3 seconds will shut off and restart again.  Continuously.
    I have:
    -taken the battery out (multiple times): continues
    -followed the advice to start in Safemode, it will start in safemode, but shuts off after 3 seconds and reboots
    -connected it to laptop via USB, but the computer will not pick up the device to be able to access it
    I have actually gotten to the screen and in the 3 second window been able to click on the Networks tray again to see that Bluetooth is no longer "checked" on--doesn't matter, still only have the 3 secs before the reboot cycle.
    Advice?  Suggestions?
    Solved!

  • Help! After interrupting an installation of a program downloaded from the internet on my mac in a reboot cycle will not start, I've already done the disk check and it's ok and I reinstalled the OS 10.8 Lion

    After interrupting an installation of a program downloaded from the internet on my mac in a reboot cycle will not start, I've already done the disk check and it's ok and I reinstalled the OS 10.8 Lion

    In this case, I think that there's something damaged that can't be fixed just reinstalling OS X.
    If you don't want to lose files, you will have to create a second partition in the hard drive and install OS X there, so you will be able to recover everything you need. Then, you will have to erase the first partition and reinstall OS X. Follow these steps:
    1. Hold Command and R keys while your Mac is starting to start into OS X Recovery, and open Disk Utility.
    2. You can follow the steps of this site to create a second partition > http://pondini.org/OSX/DU3.html
    3. After creating the second partition, close Disk Utility and install OS X on the second partition.
    4. When the installation finishes, open Finder and, in the sidebar, you will see the other partition. Open it and recover the files you need.
    5. After doing that, repeat the step 1.
    6. Select “Macintosh HD” in the sidebar, go to Erase tab and erase the disk.
    7. Close Disk Utility and install OS X on the first partition.
    After doing all of these steps (you will need a lot of time to do this), you can delete the second partition you created and add the size of this partition into the first one > http://pondini.org/OSX/DU4.html

  • Constant reboot after IOS4 upgrade Solved!

    I too was having the dreaded error 29 code and stuck in recovery mode along with the 5 minute constant reboot since upgrading to IOS4 two days ago. I had to use Blackra1n to get it out of recovery. Blackra1n will NOT jailbreak IOS4 but will fix the stuck recovery mode problem. I also had previously replaced the battery with a higher capacity mAh. the upgrade to v3.1.3 went perfect. Only when I upgraded to IOS4 did things change. It would constantly reboot and the battery was slowly draining and would not recharge. I poured through countless forum posts and tried most all of them. Then this evening I found a post somewhere in this forum about possibly the battery was causing the problem. So I got out my tools and put the original battery back in and booted up. It got to the front screen and immediately a bunch of old calendar events started popping up which was different than before. I cleared them all and I have now had my iphone on steady for over an hour and not one reboot. Battery is also now recharging off my laptop.
    So long story short, if you've replaced your battery at some point, put it back in or hopefully an OEM with same APN: 616-0434 (#for my iPhone). Everything is now working in IOS4!

  • HELP!!! MBA will not boot. It's in a constant "reboot loop!"

    Hi! I was having issues with my MBA and it's well known problem with getting a bit hot and shutting down the core etc. One post mentioned coolbook. Several peole gave it the thumbs up so I decided to give it a try. Installed it and was asked to restart. Now my MBA is in a constant reboot loop and will not start-up. it gets as far as the gray screen with the Apple logo and the spinning wheel. Then about a minute or so later it reboots. And this goes on and on forever. The MBA is now insanely hot and I have turned the MBA off not to cause any damage.
    I can not boot in safe mode.
    Any ideas??
    Thanks!!

    thanks for the views, but seems nobody wanted to help. cheers for that!
    i managed to reboot using the OS X DVD and reinstalling. Now I have an eject symbol in my system bar top right corner and my superdrive will not "eject". this means I can not use the USB for anything else. meanwhile I ejected the OS X DVD from the drive and tried to reinsert it. NADA.
    Getting to the point where I am fed up with the MBA. It gets so hot I could fry an egg on it. The system must be running something in the background, becasue even with a new install it still is slow and stutters (and no, I did not start you tube!) either this is from a real crappy batch, or I looked at it the wrong way.
    Looks like I am heading back to the MBpro.

  • Photosmart 8250 constant maintenance cycles while printing & excessive ink usage

    I'm having a problem with my trusty 4-year-old HP Photosmart 8250: Whenever I print a document, whether in color or black ink only mode, it constantly enters maintenance cycles and excessively uses ink.
    Two examples: When I printed a color document (color, HP Bright White Inkjet Paper, 17 pages), the printer behaved erratically, with constant maintenance cycles. It also said I had to change yellow ink, but when I re-turned on the printer to install a fresh yellow ink cartridge (I only use original HP ink), it still showed remaining yellow ink. Then yesterday, when I printed a 32 page graphics document (black ink only, plain paper, normal), the ink meter for black dropped from full to 25% full (I had changed the black cartridge only one week earlier), and the printer went through four maintenance cycles. Neither had happened before in my four years of owning this printer, and the black ink consumption for similar documents in the past was barely a quarter of what it was for this document. 
    Are these issues most likely related to the printhead? I know that the Photosmart 8250, like all printers with HP 02 cartridges, uses a fixed non-replaceable printhead, so does the printhead need cleaning or alignment? Or should I just get a new HP printer, as I have used this printer extremely frequently over the past 4 years?
    Thanks for all your help!

    Hi johnpd,
    There have been some significant upgrades to photo printing and the inks since the MP610 was introduced.  With the MG7120, and the XL ink tanks (which are comparably priced to the standard ink tanks used in the MP610), you should receive similar or greater page yields.  One major reason for this boost is the addition of the gray CLI-251 ink.  When gray appears in your printout, instead of using a mixture of all the other colors, the gray ink is used, reducing your overall ink consumption.
    At the risk of sounding like a typical salesman, "I want to get you in the model that is right for you"!  If you are looking for a photo printer, the MG7120 is one of my top suggestions for a quality Photo All-in-One.  If however, you do not plan to make heavy use of the printer and only occasionally print photos, you might get more value from an Office All-in-One.
    Please feel free to Contact Us if you have any additional questions.

  • Constant reboots on my iMac (early 2009) with Mountain Lion. Why?

    I know there are a number of threads here speaking of similar problems, I've tried the steps mentioned there...to no avail.
    I have an early 2009 iMac with a 24" display, 3.06 Ghz Core2 Duo. Memory has been upgraded to 8 GB.
    The problem is: Since upgrading to Mountain Lion I get constant reboots, sometimes I can't even have the machine running for more than 30 minutes without it starting again. This is making it impossible for me to work. I've posted the last panic report at the end of this message. What I've noticed so far in all the panic messages is that the last loaded or unloaded extensions are always the same ones, no matter if my machine is restarting after 30 seconds or 4 hours. Could that be something helpful?

    So it's ALWAYS either a file system extension or the USBCDC one. Always. Is that useless info or can I do some further testing in a specific direction here?
    I've done the Apple Hardware Test in a loop for more than 8 hours without any problems, I've done a memtest in terminal without any problems. I've bootet in safe mode and still got a reboot. I've disconnected all external stuff (only using a Cintiq, a DAC with speakers and keyboard/mouse anyway)
    Can anybody give me any more tips? Oh, and I've reinstalled Mountain Lion (clean install from recovery partition) a few times already. No change in behavior.

    Update: It just happened again, this time while doing a backup with Time Machine. Could it be my Keyboard?
    I'm not using a Bluetooth keyboard, but one with a USB connection. Sometimes I'm connecting my backup drive to it, but reboots also happen without anything connected to the keyboard.
    This time there's even backtrace info:

  • Upgrading from 10.4.11 to SL - reboot cycle

    Hello ... I need some help ...
    I currently have an iMac (Intel Core 2 Duo) running Tiger, OSX 10.4.11 and am trying to upgrade to Snow Leopard and am stuck in an endless reboot cycle before the install starts. I insert the disk, click on "Install Mac OS X" and I get a window that has one button, which says "reboot" The messsage says "reboot to start install". I reboot, then the disk pops out and when my computer starts again, I put it back in and it starts all over again. HELP!!! Thanks so much.

    OK, so I should have put the disclaimer, I need step by step instructions ... I rebooted (from apple menu) and held down the "c" key when the chime hits, but it still pops out the SL install CD and takes me to my usual log in. Am I doing something wrong? Thanks!

  • Torch Reboot Cycle Problem after Blackberry ID Update

    Hi!
    I started my App World to download a few new applications. It went on to ask me to do an ID update, which i did. After installing the Blackberry ID, the phone asked me to restart it, which i did.
    But now, it has gone into a reboot cycle and refuses to start. I tried starting the phone in Safe Mode, but when the screen becomes white (just before starting the phone) and i leave the 'Escape' button, BANG! Back into the reboot cycle. It doesnt even boot up in the safe mode. I tried like a zillion times to get it working in safe mode, but to no avail.
    Any help please? I need to get the phone up and running as soon as possible! A fast response will make my day!
    Model: Blackberry Torch 9800
    OS: Version 6 (never updated, so original one which came with the phone)
    Carrier: Idea (India)
    Thank you,
    regards,
    Eeshan Umbrani

    Hello,
    If you can't get it to boot into Safe Mode (which can be tricky indeed), then perhaps this KB will be useful:

  • Reboot cycle only when disconencted from base

    Hi.
    I have an iphone 1.1.4
    The screen froze while playing music and would not reboot. I did the home + power reset and it sent it into an endless reboot cycle. I attempted to restore via itunes and it gave me error 2003. After 4 or 5 tries i got it to restore, now when i remove it from the cradle a black line appears 1/2 inch from the bottom of the screen, and the phone slowly fades to white and resumes the reboot cycle. Once i plug it back into the cradle it works fine, as long as i keep it plugged in. Any suggestions? I have previously dropped the phone and it is now dented so i dont think apple warranty applies.
    this phone has NOT BEEN JAILBREAKED or bricked or whatever.
    EDIT: i tried unplugging the usb cable from the pc while keeping the phone in its cradle, and it still turns off. any suggestions would be much appreciated.

    Hi littlemisstq,
    Based on your description of the issue and the troubleshooting you have already attempted, it does sound like your iPhone may need service. You may find the following page helpful:

  • Startup Reboot or the constant reboot of Death!

    If you have upgraded to IOS7 and find that your device, iPhone, iPad, etc randomly goes into a reboot cycle you may have more than one i device on the same account. 
         I've been struggling with this for the past two months starting with iOS7.0 and then with 7.03.  I have an iPhone 5 and iPad 3.  Origionally I had updated my iPhone to iOS7 when it came out and things seemed to work fine for about four days.  Then one night the phone started rebooting over and over. I called apple support.  Reinstalled, cleanly installed, low level installed everything on my phone 6 times but the reboot issue kept occuring.  I had the phone replaced at an Apple store.  The tech at the store could not get anything from the crash logs because the reboot was a crash of the OS itself with no other app related information.  The phone was replaced with an iOS6 model and I left it that way figuring that iOS7.0 was not ready for prime time so I would wait. 
         I waited until 7.03 came out to try again.  I should mention that I had no issues at all while on 6.  Four and half days after the update the reboots started again.  I called apple again and went through the same process as before.  keep in mind when you phone is replaced you only get a 90 day warranty.  I was 7 months into a new phone so I was lucky the first time but by now I needed to pay for an apple care plan just because we could not find the problem and I was pretty sure I would be calling them again.
    After about a week of stability I decided to upgrade my iPad.  Guess what, four days later the same thing started happening.  BUT it turns out that the reboot happens to both devices at the same time when it happens.  While the iPad was on iOS6 it would not reboot but when I upgraded it the reboot cycle takes place at the same time as the iPhone.  You can't stop the cycle without getting both devices shut down.  I called apple support and we disabled iCloud and AirDrop thinking it might be some kind of conflict.  That did not solve the problem.  I called Apple care again and now this has been pushed up to development.
    The one thing I did get out of this is that you can break the cycle without having to reload your phone.  Both devices have to be powered off by holding the power and home keys at the same time.  Once the screen goes fully black release the home key and then the power.  Leave the devices off for 20 minutes and then start it up by plugging in the sync cable to the computer you normally sync on.  The device will load slowly and then work normally again.  As long as one of the devices remains off the problem does not reoccure. 
         I have not tried to create a new apple account for the iPad becasuue I don't want to buy all the software again and I have yet to hear back from Apple about this case.  If I don't get a response before the end of the year then I will probably try to get both devices replaced with iOS6 devices.  I find it hard to believe that Apple released this OS.

    Restore again in DFU Mode, write down the Error Code if any so you can look it up.
    DFU Mode means iPhone in Recovery Mode with Black Screen (no iTunes Logo).
