IMac :: Replaced HD But System Freezes On Startup
Nov 10, 2009
I have a early 09 iMac 2.93Ghz with 6GB of ram. About a month ago it kept freezing at the grey startup screen. I took it to Apple and two trips to Apple later my hard drive was replaced. One month later here I am and the problem is happening again, the same exact problem. I turn on the iMac it goes to the grey screen, the beach ball "like" thing starts spinning and then it freezes in the middle of it and I have to do a hard power off(hold down the power button). Any ideas!? I already scheduled a appointment with Apple tomorrow afternoon but its a royal pain in the a** to keep shuffling my iMac between home and the Apple store. This will be my 4th trip in for the same problem, btw.

After replacing the first one due to a surprisingly noisy hard drive, and the replacement itself being returned due to having a massive hardware failure, I'm still not using the iMac I ordered over a month ago. Funny thing is, the second iMac had the same rumbling hard drive as the first which I was prepared to put up with. With no more than a few days of usage, it just stopped working. It's been over a week since the second was returned and the new one hasn't been shipped!

I have a mac pro running leopard (purchased in 2/08) and it was running beautifully for almost 2 months with no hangs, crashes or freezes. Then, for some reason, today when I turned it on, it would not boot. It would get to the apple logo, then just sit there for a few minutes, then reboot itself and the same thing would happen. I pulled out the ethernet cable, unplugged all usb except keyboard/mouse and it would then (sometimes) boot into the system, log me in and present me with the UI.
I then quickly performed a soft reboot and it would get to the desktop. However, I can only use it for anywhere from 30 seconds to 5 minutes before it would completely lockup. The clock freezes, the mouse freezes and it just sits there forever. I have tried booting into Vista (BootCamp) and it also freezes before startup is complete. If I hold down Option and then select the System disk, it will either just hang forever or get to the desktop and then freeze again....................

Im planing on buying a 27" iMac with the quad i7. I was wondering if it would be possible to replaced the superdrive with an intel ssd for the operating system. Has anybody done this yet on a previous generation imac and how did it work out.

This is my first Mac user problem posting going back to my original SE! Power PC based imac running leopard 10.5.8 starts up but then mouse freezes after a few mins. Managed to change sleep mode to 15mins - same problem. Can't boot from Disk as same problem, also command+option and shift all still have mouse unmoved! Obvious change of keyboard and mouse have no effect. Could this be related to offspring's addition of ipad plugged into usb a few weeks back? He tends to unplug the device without ejecting!

I was off of my iMac for an hour or two so my screen saver when on. I went to wake the computer and it was frozen. I tried using the keyboard and mouse to wake up the computer from the screen saver, but it would not work, so I powered the iMac down manually from the button on the back. I let it sit for 15 minutes, then I tried to start the computer up again. Now at start up, I get to a blank white screen with the spinning moving pin wheel, and that is it.Â

Right now I'm saving for the 20" model (2.66). Would The 20" 2.66 iMac Freeze Like The 4850 Issue? Will it freeze like the upper model with wi-fi on? Making sure before I invest in an iMac.

I'm working on a Macbook pro 15 A1278 for a friend. They were given the computer by someone who didn't want it. My friend did not have the password to get into the machine and no original system disc. I thought this was going to be an easy case of erase-and-install. So I attempted to boot from my own Snow Leopard DVD, then I started getting three beep errors. Now I can't get as far as the password screen any more. Computer starts with normal chimes, then when it gets to the grey screen with the Apple, I get the "three beeps". Bought new ram, put it in, reseated it a bunch of times, still three beeps every time.Attempting to restart using the system DVD by holding the C key, same problem. DVD spins up but then three beeps. Fired the machine up as a target disk and ran disk utility via remote control from another machine, we''ll call that one "machine B". Hard drive checks out with no errors and is formatted in Extended Journaled. Did a clean system install from machine B (while still in target disk mode). System install was a success and was able to restart machine B successfully from the hard drive of the faulty machine.Â

Two weeks ago, my SSD had been broken due to the "Invalid node structure" error. I cannot fix it by using `fdisk_hfs`. Then I have to format and re-install, but got another error: "Install Failed: OS X could not be installed on your computer. OS X can't be installed on the disk because a recovery system can't be created. Visit [URL] .... to learn more"Â
Visit that article, then resize the partition and try again but nothing changes.Â
There is no other way, I have to bring it to the warranty service. They said they replaced my SSD with a new one. But now my Mac boot quite slow:- 10s from console to Apple logo- 30s from Apple logo to login windowÂ
It used to boot in ~ 11, 12s, the login window seems appear immediately after Apple logo.
Here're my EtreCheck report:Â

So, I have some questions:Â
1. Is there any way to make sure that my SSD has been replaced?Â
2. I would like to know what does it actually do from Apple logo to login window?

The last 2 days my iMac has completely frozen on me at random times. Frozen meaning, no mouse movement, no keyboard activity (caps lock not responding) and no OSX activity whatsoever. Temp at the time 41C, CPU Usage at 21% or smth, Fan speed at around 1200rpm. However, I don't get the infamous kernel panic error. I haven't changed anything hardware wise. I did have a couple of months ago the graphics glitch problem. Last software update was the iWork one. iMac is Aluminum 20' with C2D 2.4 and ATi 2600 Pro.

I have late 2007 Mac mini and I have Snow Leopard installed and I was simply watching a Youtube video and then all of a sudden the entire system freezes (couldn't move the mouse) or anything and started choking on the audio (replaying a bit over and over)... had to manually power it off. The hard drive was replaced several months ago at the Apple Store... so I doubt it's the HD. The Mini is back on now of course... it's running fine, but I've never seen anything like that before. Anyone else ever have this issue?

I have a 20" iMac mid 2007 2.4Ghz, 320GB, 2Gb machine running Snow Leopard. Today I turned it on and it was running fine. But around three hours of using it suddenly froze. I had to force the turn off using the power button. When i turned it back on it took about 4 mins to get to the login screen. Once I logged in the spinning wheel came up and the only think that loaded was the Spotlight sign. This kept happening until about the third time of turning it off and on. When it finally completed login. But it is now extremely slow and it just about freezes when I open more than one application.

I have a 13 inch aluminum late 2008 MacBook. The processor is 2 GHz Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR3 running OS X Lion 10.7.4. I am in the process of replacing my old hard drive with a new one.
My old hard drive is partitioned as follows:
Name: Macintosh HD
Format: Mac OS Extended (journaled)
Size: 132.5 GB
Name: BootCamp
Format: Windows NT File System (NTFS)
Size: 26.69 GB
When I was partitioning the new drive I did so as follows:
Name: Macintosh HD
Format: Mac OS Extended (Journaled)
Size: 973.51 GB
Name: BootCamp
Format: MS-DOS (FAT) --- This was the only option that I was given that I thought would work. I did not have the option of "Windows NT File System (NTFS) to choose from. I only run 1 program on Windows and that is the only reason I have BootCamp on there at all. However, I do HAVE to have that program. Size: 26.34 GB (I just used the same size that was current, or close to it.)
I connected the new Western Digital 1 TB through an external device, partitioned it as stated above, and then used Carbon Copy Cloner to clone the drives. It went through fine. (It took 2 hours and I went to bed before it finished.) This morning I woke to see that it had gone through well. I then started the process with the BootCamp drives.
However, before I started it gave me errors stating that I wouldn't be able to run Windows off of the Cloned BootCamp drive. So I used Winclone and it seemed to work fine. I then replaced the old drive with the new one. Then I rebooted the machine. Everything seems to be fine except when I went to restart it in Windows using BootCamp that was not an option. The only start up disks listed are the Macintosh HD.

Apple replace my 2007 (June) MBP with the version just prior to this last update (June 2009 model) on April 7. Any chance Apple would swap me with the brand new MBP or am I just S.O.L. I have heard here of people purchasing MBP (because they were fed up with waiting) a week or two before the updates became public and Apple happily swapped them with the newest version

I recently took the plunge and installed Lion after being content with Snow Leopard....well now I have quite a few issues. When I open system preferences for some reason it automatically opens to Network...why I'm not sure. When I click show all, then click sharing, I can't make any changes in the Sharing preferences without my entire system locking up. I can't force quit or anything. I can still use the mouse but all I have is the rainbow wheel!
I have searched and searched and haven't been able to fix it. I have tried booting into the Guest account and the same problem happens there. I have trashed all the plist files everyone says to try. I have tried repairing permissions etc. I feel like I have tried everything. Is there anything else that I can do without have to do a clean re-install. I'm hearing if I do this that I won't be able to migrate my files from by backups due to permission problems?
I also took a look at my system log and it is full of this!

My computer is 4.5 years old. And every winter for the past 3 years it's had troubles starting up in the cold mornings. Gradually getting worse each winter.
Today wasn't too bad.. it started up on the 2nd try. But on a particularly frosty day it might take 3 goes.
It freezes anywhere between the grey screen to the loading wheel to the desktops appearance.
Sometimes it freezes and gives the message to switch it off by the power button.
On occasion it freezes and shows me this: [URL]

My computer crashed today and hasn't been able to boot back up since. It gets to the grey screen with the Apple logo and stops. The fan then ramps itself up to overdrive.
I've started it up in target disk mode and repaired it using Diskwarrior on my macbook. It had to repair quite a bit and then it showed up on the desktop of the laptop. I can read, write and pull from it. I then ejected the powermac and started it up again to find the same problem persisting.

My 5 y.o. aluminum iMac recently went kaput on me. Problems it has:Â
-Freezes on any program after startup
-Freezes during safe boot mode; grey line won't progress past first 10% or so
-DVD stuck in optical drive and nothing works to get it out, so I can't boot from my install disk
-fsck -fy doesn't complete, and keeps timing out
-Migration Assistant either stalls the receiving computer, or just gives me "network" errors (even though I'm connected to the internet), or other errors.Â
I can't run terminal, disk utility, or any other kind of programs.How do I rescue my files from my failing iMac??

I have an old macbook, its about 5 years old, one of the first aluminum models.
It has always served me well but now it has broken.
When I try and start it up it shows the grey loading screen, I see the little stripes rotating, to show that something is loading and then... it turns off.

I have got a problem with my brand new Mac Pro. It randomly freezes at start-up and shutdown. I sometimes am able to work around the problem by turning on the monitors last or switching them off first but it does not always work and is a pain anyway. While waiting for Apple or another manufacturer to release a decently priced 4k display, I am using 2 HP 24' monitors inherited from my previous desktop.Â
One is connected via an HDMI cable (HP2405) and the other via a thunderbolt to HDMI cable with a DVI adapter (HP2448).Would I be better of using a Thunderbolt connection for both displays ? Or any other connection?

I got this problem with my MB, it freezes in the startup. I went to the Macstore and asked a technician for help. He said it could be the Mac OS or the harddrive. He said I should try the Apple Hardware Test and see if's anything wrong. I got this error message: 4SNS/1/40000000:TCOD-102.125 I've searched Google with no positive result. Does anyone in here know anything about the error message?

I'm on a G5 in OS X 10.3.9 running a few user accounts. The main one (aside from the system admin account) has quite a bit of software on it and it freezes on startup while the others work fine. I don't think its a RAM issue because I also run an external drive from time to time and it works perfectly. Something I've installed is freezing the system under the one user account but I'm not sure what.

My iMac 24 inch freezes on the apple startup screen, then it takes along time for the cog wheel to start turning, and then that's all you'll get untill you switch off. I've fixed permissions and erased and reinstalled but still same issues, any ideas for what to do next?

My Snow leopard machine hangs during startup at the screen with the Grey Apple logo. It appears there is a SW issue with my OS X boot partition. Here are facts I have learned:The computer boots fine if I hold option at startup and select my boot camp partitionThe compute boots fine if I attach an external HD with OS X 10.6Running a disk repair from the external HD, I see the following two issues that are repaired. Also, note the last line about boot partitionsAfter this disk repair, the disk will still not boot, it hangs at the Grey Apple logo.Booting in safe mode does not resolve the issue, the machine will still not boot to a desktopBooting in Verbose mode, drivers initialize with the last succesful line being the ethernet drives (I believe) and then the hangup occurs. It is unclear what state the boot process is at on the hangup.Â
This situation has happen twice in the past few weeks. The first time I did a reinstall of OS X to resolve the issue. Then, the issue appeared again approximately two weeks later. I'm hoping to avoid a second reinstall (And really, avoid this issue in the future). It seems perhaps something in the boot partition table or the OS partition, although disk utility says the partition is fine. I have downloaded Test Disk 6.13 to look at the partition table, but I don't know how to interpret the outputs of that program. Â
