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).
I have got an old iBook G4 from a friend how can't fix this problem, and unfortunatly I can't either.
I know this problem is posted here milions of times but I tried everything possible, I just can't fix it.
I don't have an Mac DVD so I can't boot from DVD to repair/reinstall.
I have tried:Booting in safe mode - same problem, it's impossible to use the computerBooting in a single user mode - I can use the command line only, but when I but it's still the same problemClearing NVRAM
I can't do anything so I don't know what's installed. I have made a video to describe excatly what's happening - but in short the iBook boots fine, Finder lauches and crashes imidieatly - you can't do anything, it's just stuck in a loop.
Here's the video (skip to 0:55 for the problem): [URL]
I have a problem with my iMac which is running OSX 10.8.5. I think the easiest way to explain this would be to just give a simple example. For example let's say I have Excel and Word both open. I shut them both down. Then I completely shut down my computer. Power off. I go to bed. Next morning I boot up and guess what? Word and Excel are now running again, just as if I had never shut them them down.
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" ?
When I turn on my iMac he does not get over the 'white' apple page and keeps on running in a loop for ours. I simply do not get the computer started again. I am completly lost. Tried it for several days to restart again.
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?
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)
Well this is an ongoing saga with my iMac. Looks like my third hard drive has gone south after 4 years. All Seagate Barracuda drives. But now I can not even boot from the the snow leopard dvd to at least run the disk utility. I tried the following: holding down 'c' and nothing, hold down options and I get the mouse cursor but nothing else.
has anyone ever tested the boot time of Windows 7 running on iMac 27'' SSD? If you boot Windows 7 on SSD with VMFusion 3 or Parallel 5, what is the boot time? I am concerned because the main reason for me to get an SSD is to get a faster Windows 7 boot time.
I'm trying to install 10.7 Lion on my wife's MBP. In the process of doing that, the Lion installer says her hardrive is not "journaled" and that I need to "enable journaling". The recommendation for that is to boot off an install CD and enable it via Disk Doctor. Seems easy enough.
Unfortunately, she can't find the 10.6 Snow Leopard CD. I have an old 10.5 Leopard disc that I put in and tried to boot from while holding the C key. The disc spins and spins, but I only see a gray screen.
I also tried holding "shift" and selecting the disc as my start up volume. Same thing; gray screen.
My questions are:
1: Is it even possible to boot off the 10.5 disc when running 10.6?
2: If not, is there anything else I can do to boot off an external volume
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.
I have a Lion-native early 2011 13-inch MacBook Pro aluminum unibody running 10.7.3.I was using it an hour and a half ago.I closed the lid, and when I came back to it an hour later, the battery had died.Plugging in to a charger did not wake it.I force shut it down by holding command+option+control+shift and the power button.Now, when I turn it on, I see the white screen for a half second, then it fades to black.The indicator light stays on and solid (not pulsating).I have tried:
- Resetting the PMU
- Resetting the PRAM (white screen for half second, then fades to black, each time)
- Booting to Single User (white, then fades to black)
- Booting to Recovery Mode (white, then fades to black)
I have tried to provide all the pertinent details as well as what I have tried.Please let me know if you need more information.

I have a MacBook Pro 17 inches (early 2009) with 2.8 GHz C2D and 4GB RAM on it. My OS is 10.6.4 and have all the latest updates installed. I have used this computer for 10 months and now it becomes so slow. I did all the stuffs that may help to speed it up (repair disk permission, repair disk, uninstall unnecessary software, only one user account, get rid of startup items), but none of them seems to work. I even went to the genius bar, but the genius there said there is nothing they can do. They suggested me to upgrade the memory to 8 gig. It will cost me at least 300 bucks to do that!
Don't want to invest that much on a old MacBook Pro. But the thing is, I have a lot of friends using MacBook that has only 1 or 2 gig memory but their computers are still way faster than mine. They can open a lot of programs at the same time but I cannot. If I do, the computer gonna be really sluggish, and sometimes crash. I also don't think it is the problem of the free space on my hard drive since I have a 500GB hard drive and 80GB free space on it. I have already tried to reinstall the system and restore it using time machine backup.
My 2014 21" iMac powers itself down after about 10 seconds while trying to startup in safe boot mode. I'm not even sure why it is trying to start in safe boot mode. I shut it down after a power outage while plugged into an APS UPS. I'm guessing that since I interrupted the auto shutdown it is restarting in safe boot mode. Either way, I get a grey screen with a big apple and a progress bar. The progress bar gets to about a tenth full and the power just shuts off.
I've tried starting up while holding the alt key to select the Macintosh HD. The same thing happens.
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.
This is my first post and I hope you guys can help me. I know what I'm about to ask has been asked numerouse times, but I still can't find an answer that satisfies me. So, I was using the screen-sharing feature of Skype and my girlfriend wanted me to show her The Sims 3 game. I was running Safari, MSN Messenger, Skype and a full screen instance of The Sims 3. My Macbook Pro crashed in the loading screen of the game and the fans turned on at full screen.Since that happened, I'm hearing the fans more constantly.
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.
I have a macbook here that is stuck in a restart loop. It boots until it gets to the blue screen and flickers and goes back to a post screen and keeps retrying. It also displays a message that a crash log was written to file xxxxxxx.I can boot into single user mode and found the folder containing the crash log, how do I view that file in single user mode? If I can't read it in single user mode how can I read it, transfer it onto usb and view on my imac?
I am moving my imac 24' from Europe to the states in my baggage. The stand mustbe removed to fit it in. Some models allow a business card or credit card to insert in the lever of the stand and the back of the imac housing where the stand is attached to. Thus oin pulling the stand levekl down with the acard inserted you will see a few srerws to unscrew to removing the stand. This is not with this imac 24' intel model number (A1225)

I've got an Automator loop that is stopping at the first iteration while set on "loop automatically" but if I set it on "ask to continue" it prompts me every time but continues to loop correctly if I have selected multiple items in Finder.
I recently set my Mac Mail preferences (using a me.com account) to send an "away message" to the senders of all incoming messages to my mail account. Little did I know the hassle this would create -- while I was away, there were problems with neverending back-and-forth away messages to various recipients where hundreds to thousands of e-mail messages were automatically exchanged back and forth from my account to the recipient that was also away or unable to receive messages. Then I really goofed up big time and sent myself an e-mail from the same away e-mail account, and I couldn't even stop it, there were so many messages upon messages it was just ridiculous. How can I avoid this problem in the future? Is there a simpler way to set an away message using Mac Mail and a me.com account?

I got a Samsung F3,1TB installed and partitioned it via firewire to Guid Partition. One the original install CD 1 is inserted the Apple logo shows up for a second, disapears and a folder with a question-mark appears.
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.
My late 2011 iMac started slowing down about 3 months ago. My hard drive then got corrupt and I restored to mac osx lion anew. It sped up a bit but still slow. Last month my iMac started doing the same thing so instead of restoreing I moves all of my files to an external hard drive. Now I rerestored once again but it didn't help. A prime example of the speed decrease is the game minecraft. Half a year ago I could run a server and run on the good graphics smoothly. Now I can even look around with only minecraft. It took me 30 min to turn on. I had to do this on my iPad because I mac couldnt make it here.
My iMac(Early 2008) 2.4GHz Intel Core 2 Duo. Its has been runing slow lately, it works alright at first but then it starts freezing and sometimes it doesn't load new tabs. I'm runing OS X Lion. Is there a way to make my computer run faster or atleast normal, like it use to run.
I have a new imac 3.4ghz - i7 with 16gbs ram that won't shut down unless I hold in the power button. I checked the Console logs but that did not give me any indication of what might be hanging it up. I also, have a Macbook Pro running 10.6.8 and it has no trouble powering down.
I am running AVID Symphony which is not qualified for 10.7.4 yet so I am not going to do the update yet.
Notebooks affected by this troubleshoot:Macbook Pro 15" 6,2 Mid 2010 (OS 10.7.3) with all Apple updates installed - 2,66Ghz Core i7 - Apple SSD 128GBMacbook Pro 15" Late 2011 (OS 10.7.2) - 2,4Ghz Core i7 - standard specs Troubleshoot : At startup, Lion freezes before the user is able to type his login/password. We see the login prompt interface of Lion, but can't even move mouse cursor.Keyboard's inactive too because system is frozen.So you must force a shutdown.And it's a loop-freezes. You'll try several times to boot your laptop before it will succeed to open. (it's a 5-times boot to succeed - average) I've tried several times: P-Ram reset, repair the permissions of Macintosh HD with latest Lion recovery & from an external boot too.None of this has solved this issue. I'm sure I'm not the only one who saw that issue. Have to boot 5 or 10 times his Macbook Pro to succeed a boot is not a normal use
I updated iphoto to 9.3 but never bothered to launch it until today. It asked me to upgrade the library. However, the process got stuff with a spinning beach ball and my mbp completely froze! When I cold booted it, it launched iphoto on its own and the whole process repeated. I had to reboot in safe mood in order to break it.In safe mode too iphoto library froze the machine.
When it wakes up it tries to connect and fails, but as soon as I choose my home network from the list it connects immediately. I have checked the box remember this network . I have tried all the tricks found on the internet and still have to copnnect manually.
