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.Â
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.Â
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).Â
I did the Apple Hardware Test (it reported - no troubles found), reset the SMC, PRAM - all to no avail.Â
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!Â
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?Â
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.
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.
Has anyone else experienced anything like this with their MBP? I woke my MBP from sleep as I went to do something on it and I found a checkerboard-like (or interlacing) pattern displayed across the screen. That is, I could see bits and pieces of Firefox, the desktop, the dock, etc. in little rectangles across the screen with the bits and pieces scattered all over the place (like puzzle pieces strewn everywhere). I wasn't entirely surprised as I had seen a friend of mine have a similar problem when waking his MBP from sleep. I didn't have time to deal with a restart, so I went to my gf's Windoze machine (perhaps what follows is my MBP taking revenge for going off when times got tough and cheating on it with a *gasp* PC!!???). when I returned to my machine later on, it sounded like it was rebooting itself as I walked in the room. Then about 15-20 seconds later, it did the same thing. When I opened it up, the same checkerboard pattern appeared as it started to reboot, then it went to a completely blue screen, and finally went black (as in turned-off black). After that, it started this same process over again and stayed stuck in that loop until I held down the power button to turn it completely off. I called Apple (still under 90-day Apple Care since I got the machine in April) and did all of the troubleshooting tasks that they talked me through. It is apparently a hardware issue, as I feared, and I will have to send it off to have it repaired. (At least is sending the pre-paid box for me to ship it to them).
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?
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.
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?
"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.Â
I have a Macbook with OS X version 10.5.2. After being prompted to restart my computer while doing software updates, it brought me to a screen telling me to restart my computer. Every time I restart it, it takes me back to this screen, I can't get it to boot!
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" ?
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?
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.
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.
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.Â
With any movement of the cursor, when playing Youtube and other flash video's, the video's stutter and get stuck in a loop repeating very fast then playing then repeating... I am running 10.6.8 with the latest version of Adobe Flash Player 2GHz Processor and 4GB 667 MHz DDR2 SDRAM.
My parents are having the exact problem described in this thread (and I've been tasked with remote tech support): [URL] Upon startup, WinXP gives them a BSOD reboot loop while indicating that a DLL file is possibly corrupt. Booting in Safe Mode won't work, and reverting to an earlier snapshot merely delays the problem by 24 hours or so.
The obvious and ideal solution would be to boot into Repair mode from the install disc and copy the clean DLL to replace the damaged copy. The problem is that, according to the thread, I'll need to first get Fusion to accept a floppy image of SCSI adapter drivers for me to even be able to enter Repair mode. The link for that image was broken in the thread, but a little Googling directed me here: [URL]
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.
I installed a second hard drive, installed iphotomanager, merged some iphoto libraries onto the new drive and all was working fine. I changed some permissions ("unlocked" all of the drives as the merge was having trouble writing to the new drive but then it worked fine after I unlocked). Then I started getting the message again that it could not write to the iphoto library plist and the merging stopped working. So I thought maybe if i restart the computer, it would sort itself out but noooo, now it won't start.
It just starts to power up then you hear the drive die down. Tries over and over. So I took out the new drive I'd merged all the iphoto libraries on (which had been working fine until it didn't). But i suspect it had to do maybe with me changing permissions in the middle of the process maybe?
I tried restarting in safe mode, by holding down the shift key when I heard the start up tone until the grey screen with apple logo and spinning wheel appeared, and it takes longer now, but still ends up trying to restart and never gets to the login screen.
I have my Mac Pro installation disc 1 but can't find any others. I have Disk Warrior 4.0
But I can't get the disk drive to open since it won't start.
I emptied my cache on Safari and my computer stayed frozen for a few minutes. I decided to re-boot, but every time I do so, it goes from the gray Apple screen to a blue screen and stops right there. I don't get the spinning wheel, but rather the black arrow that I can move about the blue screen, but nothing else.
Here's what I've tried with no success. 1. Re-booting via Safe Mode (Command-Shift). Instead of freezing on the blue screen, it asks for my password and after a few seconds it stops on the Snow Leopard Pink/Black Stars background. Same result, only the background is different 2. Resetting PRAM - No luck 3. Re-booting with the Snow Leopard DVD and using Disk Utility. I follow the necessary steps online. No luck
My sisters 1GB iPod Nano is stuck on the Apple Logo Screen and will not shut off or reset by holding the buttons down. It doesn't mount or open iTunes when plugged into a computer.
I have a new imac. I was stuffing the web, tried to upload a picture, the website locked up, so I hard booted my iMac. Then when it came back on, and I get is the start up sound, and a gray screen, nothing else. Its been 5mins now!
Using my Mac earlier today I lost all sound output, and attempted to reboot it to try and fix the problem. Now instead of booting it's stuck on the white loading screen. I've tried turning it off and on again from here, but I still get the same result.
I was using my Mac (Macbook Pro 15" screen) and tried opening a file in GarageBand, at which point a warning message came up saying something about a midi file and something not being allowed, and then froze, resulting in me having to switch the computer off from the power button and restarting (Sadly I didnt realise that this would be the start of a whole host of problems and didnt make a note of the warning message). After rebooting I got the 'stuck on the blue screen with the Apple logo and infinitly spinning wheel' problem that i've seen in a few posts. having tried numerous suggestions posted with no change I ended up taking it to the genius section of an Apple store. When i got it back they said that it may have been a corrupted file, and that they re-installed and reset the starting programs (Something along those lines, I cant quite remember). I can now get onto the computer and use it, though some new problems have arisen.......
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).
I forgot my admin password on my iMac recently and so i used the reboot with OS X snow leopard install disc to reset the keychain, but now on my login screen, it used to be just my account name, there is one called "Other" so i went into accounts in system preferences and tried to delete it but it isnt there?is really annoying me p.s. the "other account" isnt actually an account it says "Other" and when you click on it asks for your username and password...so i type in the admin accounts name and password (admin account is the only one on this computer), and it just opens up my admin account.
My imac is 10.4 tiger which over the years is now updated to version 10.5.8. It regularly crashes and is getting worse - at least twice a day then i have to turn it off with the power button. When i go to reboot a folder with a question mark appears on the screen. I usually then have to turn it back off and wait several hours for the mac to reboot again...Â
