OS X :: Macbook Pro Won't Boot - Stuck In Loop

May 19, 2010

This morning I went to use my laptop, Screensaver passsword box came up and it wouldn't recognise my password at all, So i rebooted. Now my macbook doesn't get any further then the apple logo with the progress wheel then after a while it reboots. So far i've tried the following:

1.)Reset PRAM
2.)Ran Disk Util from install disk and repaired disk permissions
3.) Booted into Safe mode

None of the above have made any difference at all? I thought about "repairing" the install of os x but the version on my disc is older than the version on the laptop so it won't let me?

Jun 26, 2014

"When I login, my laptop flashes my desktop background and immediately takes me back to the login screen" Worked late into the night doing things with my laptop it worked fineThis morning when I got into the office I plugged my laptop into my second screen and noticed I only had a desktop on the 2nd screen the laptops screen was stuck on dashboard.  (I could create new desktops, etc. on my 2nd screen just fine)I unplugged my secondary monitor and saw my desktop come up on my primary screen.Suddenly another flash and I was logged outNow when I enter the correct password it looks like it is starting to log in, my grey lock screen becomes my factory blue desktopthen it flashes back to the login screenIf I enter the wrong password the input box does the typical left right shake.

MacBook Pro :: Stuck In Loop At Login After 10.6.4 Update

Jun 17, 2010

This is my first mac, I installed the 10.6.4 update the other day and restarted, since then it has been on or sleeping. I just shut it down and turned it on again and it's asking for my password. Each time I enter it goes to load and then comes back to the log in screen. I know I have the write password because it's a simple 4 digit one that I use for my bank account and if I enter anything else the box shakes and asks me to re-enter it. How do I log in?

OS X :: MacBook Stuck In Infinite Reboot Loop After 10.5.8 Update?

Aug 13, 2009

I got a 1 TB Western Digital external last night and had left it on all night so that Time Machine could back me up a few times. Then this morning, I had disconnected the drive and decided that I ought to update to 10.5.8 because Software update had told me to the day before. So I did, and I walked out of the room after it started installing the update. Then I walked back in when I first heard the startup chime and the fans were running at 6000 rpm and the screen showed the Apple and the daisy wheel. It proceeded to turn itself off, and repeat the process, always getting stuck at the Apple logo screen. So I tried booting it up in safe mode, but nothing changed; it never got past the apple screen. Then I booted from the install disc and used disk utility to verify the disk and repair the disk permissions. I tried starting it up a couple of times after that and nothing had changed. So I booted from the install disc again and was going to reinstall Leopard, but I decided to restore from one of the pre-10.5.8 Time Machine Backups.

MacBook :: Stuck In Restart Loop After Software Updates

Oct 5, 2009

So yesterday I updated a bunch of programs on my macbook via the auto update function. Some of the programs I updated required a restart, which I performed when it prompted me to. Now my macbook won't restart all the way. It turns on and gives the chime then goes to a gray screen with an apple on it. After about a minute a spiral loading image appears underneath the apple and about a minute after that the computer shuts off and immediately restarts again only to do the same thing (its stuck in some sort of cycle). I've tried resetting the PRAM and a few other things but nothing seems to work.

OS X :: Upgrading From 10.2.8 To 10.3 - Stuck In Loop

Apr 19, 2009

I was trying to upgrade my girlfriend imac g3 500mhz from os 10.2.8 to 10.3 . The installer soon told me that I needed a firmware upgrade and quit, and restarted the computer. I then got stuck in a bit of a loop and had to use a paperclip to get the disk out. Now when the imac is started, for a couple of seconds a small icon of the os face (?) appears and flashes to a small icon of a folder with a question mark on it (that scared me) but then is seems to start up and run as normal! I've turned the computer on a couple of times now and it does exactly the same thing every time. This flashing image is worrying me, I've given up on the idea of installing os10.3 but have I damaged this IMac?

PowerPC :: G3 Stuck In Rebooting Loop

Oct 22, 2009

My G3 keeps repeatedly rebooting. It goes through the loading process, but when it comes time to give you the desktop, it shuts down and restarts all over againl. As it boots up, a double image that you can't read comes up on the monitor, along with a solid color bar that separates the desktop image in two. I have two internal harddrives and changed it to reboot from the second harddrive, thinking that might be the problem. Immediately after doing this, it rebooted fine one time, but now is caught in the reboot loop again. When I startup from the install disk, the image is fine on the screen, as is the startup itself and when I run disk doctor, it says both drives are fine. I homeschool and would like to keep using all of the classic educational software on it for my 5 year old. It's running 9.2.2, 256mb memory 9gig drive is current booting drive, other one is 2gig.

IMac PPC :: G5 Stuck On A Reboot Loop

Jun 4, 2012

I received an iMac G5 from this old couple, they were going to throw it out, but all it needed was a power supply which I bought and replaced. It's been about 9 months and everything worked great, no problems whatsoever. 

Three days ago, I shutdown the computer and when I booted the next day, it would only reach the Apple logo and the spining wheel, the fans would blast loud and then it would shut down and restart again, repeating the same thing over and over.  I cannot start it under Safe Mode nor it recognizes the CD when booting.

OS X :: Time Machine Stuck In Loop Running SL?

Aug 29, 2009

I installed SL a few days ago and had to rebuild my Time Machine backup. It powered through all 700GB today and then it kept going. The progress bar got to the max: 700/700, then went to 700.02/700.02 ,, 700.03/700.03 ,, 700.04/ 700.04 ,, etc. Currently it's adding onto the "inprogress" file and filling up the drive with more data than I had to backup! It's done 844GB out of 700. Keep in mind, this is a totally-from scratch backup here! Do I stop it? Do I wait until it fills up the drive and "figures it out" ?

Software :: IBook G4 Os X 10.4 - Stuck In Reinstall Loop

Dec 12, 2009

My iBook G4, running Tiger, is stuck in a loop. While trying to reinstall os x 10.4 I was instrucked to insert disc 2. So I did. Resulting message: "There were errors installing the software. Please try installing again." with "close" the only option. So I close. It spits out disc 2 and message pops up: "please insert dics 2 to continue installation." The only way out is to crash but there's not really any way out because, when I re-boot I get the "there were errors installing" message and around and around we go. I tried to boot to my hard drive from the install disc but it won't go there. I did the hardware test and it says all is well.

Intel Mac :: Stuck In Reboot Loop (even After A Reinstall Of OS From DVD)

Jun 10, 2012

I have a 6 month old iMac (bought Dec 2011). It has 10.6.8 with all patches. It began to randomly shut down and got stuck in the reboot loop (sometimes, the problem was a reawakening after sleep, but even a simple shutdown/restart wouldnt guarantee correct behavior). 

I did the Apple Hardware Test (it reported - no troubles found), reset the SMC, PRAM - all to no avail. 

Finally, i reinstalled the OS from the DVD that came along with the iMac. Left it for a few hours to download the "jumbo" patch from apple site, and now it is back to behaving the same way - it is stuck in a reboot loop! I dont know if it installed the patch or not, as soon as i touched any key to wake up the iMac, it rebooted (like before). And now I gotta try the boot process like 15 times and it may boot correctly. Safe Mode boot is also not guaranteed to work. It shows the sliding bar and then back to reboot! 

If it were a software issue, the reinstall of the OS should have fixed that? If it were a hardware issue, the AHT should have caught that? Am I stuck with a lemon? Just one of those bad pieces that are inevitable in any assembly line production?

MacBook Pro :: MBP 7/Immediate Boot Loop After Startup Chime

May 6, 2010

I have a mid-07 Santa Rosa MBP. When I turn it on, nothing comes on the screen (not even backlight), but I'll hear the startup chime and 2 seconds later, it reboots and does the same thing. Here is what I have tried:

1. Reset SMU
2. Reset PRAM
3. Replacing HD
4. Replacing PRAM/CMOS battery
5. Tried booting off DVD (but it reboots too fast after the chime)

OS X :: IMac Screen Black. It Got Stuck In A Loop And Froze.

Jul 30, 2010

I was playing Diablo II and my screen froze, and the same half second blip of sound kept playing over and over. I couldn't even force quit, so I held down the power button until it turned off.

Now, it won't turn on. When I press the power button, there is no chime. Oddly there are an inordinate number of fan wooshes. Like, I hear a woosh from the right, which is normal, but then I hear a woosh from the left, then another in the middle! I am being bombarded with wooshes!I've tried holding alt, or holding shift, or holding alt+s while starting up. No dice, although I do get fewer fan blasts, which is normal.

OS X V10.7 Lion :: Address Book Stuck In ICloud Loop

Jun 20, 2012

My address book has suddenly gone haywire. It contains nothing 'on this mac' and seems to be stuck in a loop of downloading from iCloud - it gets a few contacts, then more, then yet more, then all, then back to just some and goes through the cycle all over again. Looking at the plist files in the library com.apple.addressbook.plist keeps vanishing and reappearing. I've tried quitting address Book, deleting the plist files (all of them) then reopening, but problem persists. I've tried turning off the iCloud sync for Address Book, whereupon it asks me if I want to keep a local copy: I say yes, but nothing is copied. Turn it on again, it syncs and starts looping all over again.

OS X V10.7 Lion :: MBP Stuck On Login Screen / Password Loop After Latest Update

Apr 3, 2012

I just literally updated my macbook pro to the latest version of Lion, today 4/3/12 and now it's just stuck on the main log in page for lion. As in, I type in my password, it thinks for two seconds, goes black, and has the log in page again. It just loops. No end in site. I've rebooted in safe mode, run disk utitily, and repaired the disk... but no dice, still. It repairs the disk, fine right? When I reboot in regular mode, it just goes back to the password/login screen loop.

OS X V10.7 Lion :: IMac A1225 Crash Running AHT Then Goes Into A Boot Loop

May 1, 2012

I have an iMac A1225 EMC2211 that is exhibiting some weird behaviour. After about 5 minutes of using it (cold boot) it will either have a kernel panic, freeze and go into a blue (bondi blue I think) screen, or shut down. I ran an extended AHT on it and after 10 minutes it shuts down (black screen) then goes into a boot loop (screen stays black and system chimes once every 2 seconds). If the system is warm it will not boot (goes to blank grey screen). The consol reports something with the NVRAM (havent had the ability to post the log yet).

OS X :: Blue Screen Startup Loop - Video Driver On My Boot Camp?

Dec 27, 2010

some reason my Macbook Pro 15' inch won't start up. It's stuck at the blue loading screen after the gray Apple. The screen switches from two blue colors every 5 seconds or so along with a loading symbol. Sometimes I can see my mouse and use it, but that's all what is happening. The last thing I did was installing the newest video driver on my Boot Camp. (Windows 7 - 32bit and Leopard 10.5 for mac)
I can still start up Windows 7 without a problem on Boot Camp, so it doesn't seems a hardware issue. I already tried some stuff found on the internet, but I can't start up 10.5 in normal or safe mode.

Mac Pro :: Stuck At Gray Boot Screen - Boot XP

Apr 27, 2008

trying to boot in Leopard my Mac Pro will get the the gray loading screen with the "loading circle" and just sit there forever. Than after a bit it will just stop and the whole computer can shut itself down. I just installed the 8800gt upgrade kit last week, and have had no problems at all for the past week. The only thing that changed that may be related is the 8800GT XP Driver. I installed the latest beta driver for it under XP in boot camp because it wasn't working properly with the default boot camp drivers. So I can correctly boot in the XP via boot camp, but trying to boot in Leopard it just hangs at the gray loading screen.

MacBook Pro :: Stuck At Apple Logo (no CD Boot Either)

Jan 22, 2010

I have a major problem with my first Generation MacBook Pro. It won't boot anymore: it just turns on and gets stuck at the Apple logo. There is no spinning wheel and nothing else happens. Pressing 'C' for booting from CD or pressing ALT and choosing the CD as an alternative boot source does not work either: it just does exactly the same, gets stuck at the apple logo. I already tried resetting the PRAM and NVRAM, as well as the SMC. This also did not change anything. CMD+V mode starts up then stops at the line "ACPI: System State [S0 S3 S4 S5] (S3)"

What can I do? I really need to save my Mac, there is some really important stuff on there

MacBook Pro :: Stuck At Grey Boot Screen

Jun 29, 2012

So yesterday i turned my laptop on to find out it wasnt booting up past the grey screen. Later on i did some trouble shooting and finally got it past to the main desktop screen. Now, recently i had just uninstalled and deleted my Windows 7 Pro partition i had put onto my laptop a while back but when doing so, when i tried getting my hard drive back to full storage amount by deleting the partition,it gave me some error. I believe i figured out the error and was able to use my laptop from then. Once my computer was letting me get to the desktop screen, once i would click on an app it would often give me the pin wheel and stop me from clicking on anything else for a good minute.

Today,i had backed everything up and thought that i would just reformat and re install OSX to remedy the whole issue. This was not acheived. I had been able to get to the desktop screen a few times but still got the pin wheel situation going on. A couple tries later im stuck here at my grey boot screen. No Apple sign showing up, just stuck. Im usually a very computer savey person but this is kind of just making me wonder. I ordered a new hard drive (which i was going to upgrade anyways)but wanted to know if this even could possibly be the issue. I upgraded from my stock hard drive about 6 months after i had gotten my laptop (mid 2009 model). The last 3 years ive been traveling very often, flying frequently and using it often for playing my DJ gigs. Im wondering if alltitude and hot clubs could take a tole on a hard drive when its running hot?

OS X :: Macbook Stuck On Gray Apple Boot Screen?

Aug 23, 2009

Last weekend, my white Macbook was requiring a software update to 10.5.8. So I said, go for it and let it restart. That's when the trouble happened.

It began to restart but just stuck on the gray apple screen with the gear circle thing spinning. I tried several times to restart, but it never worked. I did all the things I knew to do (boot from DVD and run disk utility to repair permissions, zapped PRAM, ran it in the fsck thing; Booting in safe mode wouldn't work). So I booted from my backup and used SuperDuper to rewrite my boot drive. (I guess I should point out that when booting from my backup, I was able to access all my files on my internal HD, it just wouldnt boot). After doing that revert thing to 10.5.7, everything worked fine.

So then I tried to update again this weekend. Same thing happened. I've tried the same steps. I can still get to anything I've added to my regular drive since my backup and all that. Just won't boot from that main drive.

OS X :: Macbook Won't Boot - Stuck On Gray Apple Screen?

Jul 8, 2010

I have a four year old Macbook that's not in the best of shape, but it hasn't failed me like this before.. ever.

I installed a new security update yesterday morning along with the new iTunes, and it worked alright for most of the day.

Around 10:30 or so, it just shut off.

I tried to turn it back on and was faced with the gray apple logo and the horrible spinning icon.

I've tried booting it up in safe mode, verbose mode, and even resetting the PRAM, and nothing works!

It eventually did go to a blue screen after maybe three or four hours, (I fell asleep so I'm not sure) but it still wouldn't let me do anything.
