MAJOR Start-up Issues: Can my imac be saved?
Hello all-
I sure hope someone can help me. I am really worried about the state of my imac. It is only ONE YEAR old and has always been maintained with the latest updates.
Quick background: A few weeks ago, while in screensaver mode, I returned to my mac to find a white screen with a folder and a question mark. I had never seen this before! It was frozen. I had to force shut down by holding the button on back. Since that time, the same thing has sporadically happened when the computer was in screensaver mode. In the last few days the problem has worsened with start up issues. Yesterday, when i started up the computer I kept getting just a blank white screen and what sounded like "a slow revving" of the disc several times and then nothing. After continually trying to restart (including in Safe Mode) eventually I got the apple logo and it started. When that happened, I immediately backed up everything for fear my hard drive is dying and then began to troubleshoot.
What I've tried: After looking through the threads I have tried a number of suggestions.
- I repaired the Disk using First Aid (it says all was Okay)
- I repaired permissions
- I disconnected all cords & reset the SMC
- I booted from the disc & ran the Extended Apple Hardware Test (it said all appears Okay)
After doing these things last night, the computer started up several times just fine so I shut it down for the night.... which brings me to this morning!
Start up was MUCH worse than yesterday. Same slow revving sound, white screen and nothing (at least 10 times) - even when trying Safe Mode. Then it worsened to a black screen and no sound at all - as if nothing was happening. I thought it was dead! I unplugged the power cord for 15 seconds and tried again - this changed it back to the white screen and a sound of more revving power. After about 3 tries, I got the apple logo and the spinning wheel for about 2 minutes - then it started!
This is where I am now. I am afraid to turn it off and not sure what else to try. I thought after all I did last night, the problem was fixed. Why does the hardware test and repair disc say all is fine? And why after doing those things last night did it start up numerous times? (and speedy too!) But then this morning I'm back where i started.... ? How can I troubleshoot this problem further?
I would really like to try everything before resorting to taking it in. Money is tight right now.
GREATLY appreciate any advice!
Thanks a lot,
Karen
Warning!! ** (See bottom of post)
New Development: From Disk Utility, I chose to run "verify disk" again. (Somewhere I had read that sometimes, it needs to be run a few times before it will find a problem with the disk).
Sure enough! This time I got errors and it suggested I repair the disk!
Errors in verify mode were in RED as follows:
Invalid index key
The volume Macintosh HD needs to be repaired
Error: Filesystem verify or repair failed
I then restarted with the system disc, opened First Aid and chose Repair.
The following showed up in RED during the repair process:
Invalid index key
Incorrect number of thread records
Invalid directory item count
volume bit map needs minor repair
Invalid free block count
volume header needs minor repair
And finally in GREEN (after 10 min):
HD Repaired Successfully
** After doing this, and trying to restart, i get the white screen and the spinning wheel indefinitely. (even when i try Safe Mode) It appears I can no longer boot my HD. I wanted to share the errors above incase it brings anyone to any further insight, but I'm not so sure it helped my situation.
Suggestions?

I have a 12 year old Imac - Rev B. - System 9.2... 4 Gigs Hard Drive... 168 RAM...This computer has worked very well... never a problem until now.
I am a teacher. I was using this computer in my classroom. It was able to surf the web... most of web pages displayed correctly. I just wanted an alternative to the crappy Dells the school district sticks in every other teachers' classrooms.
The problem... today it won't start up... no chime.. no lights... nothing... dead... it's plugged in, connected correctly... I press the power button... nothing...
Is there anything I can try before sending it to the big network in the sky? The Rev B iMacs are a bear to take apart, could a dead battery cause this? Can this Imac be saved? Any help would be great appreciated.Here is a picture of the battery that you need.

MAJOR Open Directory issue: Can't assign Users and Groups that DO exist!
Just noticed the following today:
When doing Get Info -> Permsissions on files/folders located on my File Server share, Owner and Group show as (unknown).
When I go into WGM -> Sharing, and look at files/folders on File Server share this way, the Owner and Group fields are blank.
When I attempt to (re)assign an Owner or Group by dragging them from Users and Groups section of WGM, error tells me User or Group no longer exists. These Users and Groups clearly do exist in WGM -> Accounts.
When I look at files on File Server share via CLI, instead of actual names for Users and Groups, I see their uid and gid's. Chowning via CLI fails as well.
I've noticed all Users and Groups with this issue are OD.
Server is xServe G4 DP 1.0 GNz/1 GB RAM/Mac OS X Server 10.4.7 Unlimited. This servers been running fine as an OD Master for months now. ACL's are enabled on this File Server share point. I've always had weird permissions issues, but NEVER the inability to assign OD Users and Groups to files/folders.
I'm at a loss here, not to mention my wits end.
Did my OD become corrupted?
Any and all help would greatly appreciated.
PowerMac G4 733 MHz Mac OS X (10.4.6) 512 MB RAMWhen doing Get Info -> Permsissions on files/folders located on my File Server share, Owner and Group show as (unknown).
This means that the Finder can't find a match in the accounts/groups database for the numeric UID assigned to those files. Either the records associated to those accounts have been deleted, or the database is corrupt. In either case, you should restore a copy of it from backup.

I am having start up issues after installing lion
after installing lion on my mac mini it is having major start up issues, sometimes it will not start up at all. Is anyone having the same issues?
After I used MIgration Assistant on my new Mac Mini, Lion would have kernel panics shortly after startup every time. I am pretty sure it was some virus software or network filterting software that ran background tasks that was causing the problem.
Can you startup in single user mode or safe mode?

Our iMac isn't loading a specific website (we get a message saying it can't connect to that specific server), regardless of browser (I've tried it in Chrome, Safari, and Firefox). However, the same website, which is for a major medical provider, loads without any issue on our other computers on the same wireless network. Is it an issue with the iMac's settings? All other websites seem to be loading without issue on the iMac.
... Is it an issue with the iMac's settings?
Possibly. Make sure you are not using a proxy server. Look in Safari Preferences > Advanced > Proxies > "Change Settings..." This will take you to the applicable Network Preferences. Make sure that nothing is selected in the "select a protocol to configure" list. It should look like this:
Still not working?
Locate your Terminal app. It is in your Utilities folder. Open Terminal.
In Terminal, copy (triple-click) and paste the following line:
osascript -e 'tell application "System Events" to get name of every login item'
This will produce a list of all your account login items.
While you are in Terminal, copy (triple-click) and paste the following line:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
This will produce a list of all non-Apple kernel extensions. There will be few, if any.
Post the results of the above. -

Can you use a start up disc on an iMac without formatting the hard drive?
Yes, because the startup disk is read from the boot rom, not the Hard Disk.

I purchased an iPhone 3 and had taken some photos on it. I started having issues within 30 days and could replace it. So I created an iCloud account and saved those photos as a back up on iCloud. I did not restore my new phone from back up because I did not realize I needed to restore and not just activitate it. How can I save the new photos, apps, and other stuff but retrieve the old photos?
If all you want is your old photos, you could backup your new phone using iTunes, then restore it from your iCloud backup, import the old photos to your computer, then restore it from the backup your made in iTunes returning your newer data to your phone. If you want your old photos on your phone, sync them there from your computer using iTunes. The process would look like this:
Connect your phone to your computer, when it appears in iTunes on the left sidebar right-click on it and select Transfer Purchases; right-click again and select Backup.
Disconnect from your computer and go to Settings>General>Reset>Erase All Content and Settings to return it to new
Go through the activation setup, choosing to Restore from iCloud backup. Make sure your phone is plugged into a charger and has access to wi-fi as this can take hours to complete.
When complete, without connecting your phone to your computer, open iTunes and go to Preferences. On the Devices tab check "Prevent...from syncing automatically"
Now import the old photos to your computer (see http://support.apple.com/kb/HT4083)
When done, open iTunes, right-click on the name of your phone on the left sidebar and select Restore from Backup, choose the backup you made in step 1.
Go to the Photos tab and select the photos you want to sync to your phone and sync. -
I have an iPhone 6. For the first two weeks my bluetooth worked fine but then started having issues. Now, although it shows that it is connected to Bluetooth, I can't hear any of the calls. The radio continues to play. Please help!
Hello there, Srushevics.
It sounds like you may be having issues with the connectivity of your iPhone with the Bluetooth in your vehicle. The following Knowledge Base article offers up some great steps for troubleshooting that Bluetooth connectivity with your iOS device:
If you can’t use a Bluetooth accessory or car kit
To resolve the issue, you'll need to first sign in to iCloud and review your devices:
Sign in to iCloud on your iOS devices and Macs with OS X Yosemite (available this fall).
On one of your devices, tap Settings > Bluetooth and look under My Devices. You'll see all devices that are connected to Bluetooth, but make sure that you see your Apple devices that are signed in to iCloud and are using iOS 8 or OS X Yosemite.
Sign out of your iCloud account from any devices that you don't want to use. To sign out of iCloud on an iOS device, tap Settings > iCloud > Sign Out.
Then, remove any inactive devices from iCloud:
Sign in to iCloud.com.
Select Find My iPhone.
Select any devices that aren't active anymore.
Wait for Find My iPhone to stop trying to find the inactive device.
You should see the option to remove this device from your account. Select it to remove the device.
After following the steps above, restart the device with the issue. Then try to use it with your Bluetooth accessory.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro. -

IMac 21.5 (mid 2010) screen start-up issues
Hi
Last week I started having problems with my iMac.
The screen is breaking up during start-up with loads of small squares in a grid. Then the screen goes blank grey the grid of squares come back and start-up gets stuck.Please see image.
Any help would be appreciated
Thanks
ScottDoesn't hurt to make some trouble shooting before taking it to repair. But before making tests make sure to take backup of your data. Start by starting up in “safe mode”.
1. Shut down your Mac and wait 10 seconds.
2. Press the power button.
3. Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.
4. Release the Shift key when you see the gray Apple logo and progress indicator (spinning gear).
To leave safe mode, restart your Mac normally without holding down any keys during startup.
Once you have your data in safe place try to make some test to determine if this is a hardware related problem or something else.
To start with follow these simple guides:

I apologize in advice if this story is discombobulated or more information is needed to provide me with an answer. I will do my best to provide as much details as possible, but this is a problem that has been occuring for the past few weeks and some things I've forgotten the specifics of.
I will start by explaining that my iMac specs are:
Processor 3.06 GHz Intel Core 2 Duo
Memory 4 GB 1067 MHz DDR3
Version 10.6.8
I've owned this iMac since about April of 2010. I've never had any problems with it until recently. At one point in time, I had a Boot Camp partition made in order to install Windows, as I wanted to run some games that weren't available to Mac users. After awhile, I eventually bought a Windows Laptop for my gaming needs. When this happened, I decided to erase previously stated Boot Camp partition in order to free up more space on my hard drive.
After a few months, had major issues involving a trojan virus on my laptop, it destroyed my hard drive, and I wasn't able to buy a new one at that time. Recently decided to try and create a new Boot Camp partition to reinstall Windows. When I attempted that, (I apologize, I don't remember the specific error) it wouldn't allow me, and from what I remember after doing some google research, it sounded like somehow my hard drive had become disorganized, and needed to somehow be reorganized.
At some point in my google research I found that using the Repair function in Disk Utilities would possibly help. When I tried that, (the only reason I know this is because I tried just now to get the error to pop up) I'm given a message "This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
So here I'm thinking, "okay! No big deal! I have the disk still, I will just back up my hard drive to an external hard drive". So I buy an external HDD, back up everything I need. I then put the disk in, and my optical drive spends some time thinking, then spits it back out. It does this repeatedly. I do some more google research, find that optical drives crapping out on mac users isn't all that uncommon. I try to clean it with a trick someone suggested. I then tilted my iMac to one side, it accepts a cd! I try it again, and I'm no longer able to trick my iMac into reading disks. Sad face.
Instead of hefting large sums of cash at Apple to replace my optical drive, I buy a far more affordable external cd/dvd drive that is working perfectly fine. So after waiting for that to be delivered, 3 days later, I'm excited to finally get a clean install with my OS X drive. At this point, I care little about repairing, and have decided to just completely clean install. I restart my iMac, boot from disk, and I get the spinny thing for about 20 minutes. I think, "hmm... should it take this long?" So I reboot and try again. Same thing. I then let it run overnight, and wake up to spinny thing. When my Mac is on, it reads the dvd just fine. It just won't boot from it and let me start the clean install.
So then I get the idea maybe I can do a remote install of the disk from my friend's macbook. No such luck, won't seem to recognize anything. Then I see that I can make a copy of the disk image to my computer, and burn that image to a partition made on my external HDD, so that I can boot from that. Well, the only info I could find was a gentleman burning a downloaded version of OSX Lion, but I figured, "hey, its the same thing, right?" I guess not. I tried copying the image using the restore function in Disk Utilities, and it does indeed show up when I hold Option at start up, but booting from it does not start up properly. It starts up like any normal time I restart. I'm thinking its cause the way I copied it didn't involve a .dmg file.
So I try to copy the image to a file on my computer, but when I do that, I get some sort of input/output error.
What can I do at this point? I thought I originally set up Time Machine but when I checked recently, no such luck. All I want is a fresh reboot of my Mac. I'm guessing somehow my hard drive became corrupted in some way. I mean, it truly doesn't seem to be affecting anything, except somehow even after deleting all known movie, music, game, etc. files, I still am using up 270 gb of space. Maybe I never un-did the Boot Camp partition properly and kinda screwed myself on this one.
I've tried just about everything. I never invested in Apple Care, but even had I done so, I think it would have exceeded the warranty, as I had thought it was 2 years. I could be wrong, either way, its water under the bridge now. I need to fix this myself. I'd still like to use my iMac for general use, and to utilize the 1 TB of storage it possesses.
Any help is greatly appreciated, sorry for the wall of text, its been a complicated few weeks. Thanks!Whew... never buy an iMac or Laptop from Apple without the 3 year extended AppleCare... well 2 years extended... & I think they should be called on this, they should come with a 5 year Warranty, with more available if you want.
I think, "hmm... should it take this long?"
No way, Houston, we haave a problem, not sure what... RAM, Logic Board, etcd.
Tough without the Install disc, but some things to try...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

I cannot get MLB gameday any more on this computer. Windows 7 starter. I can get it on IE. Why?
I used to have no problem getting Major League Baseball Gameday on my netbook. However, it might be since the latest version of Firefox, I cannot access it any more. My netbook has Windows 7 starter. I can get it with IE but I don't like using IE. I have no problem accessing the site with my laptop which uses XP. Any idea why? Also having problems accessing the MLB media center.
MLB media center is http://mlb.mlb.com/mediacenter/index.jsp#20080515For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes (similar to those above) and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if iTunes won't install normally.

I sent an email with the Apple Mail app. When I clicked the send button, both the normal windows closed but the app still showed the open mark in the dock.I couldn't get the window to open, so I tried to quit. After a couple timed out messages, I got it closed only to have the same problem quiting Mozilla.I tried to shut down normally, but had to hold the power button in to turn it off. Now I'm having trouble starting up. I used the disk tools on the install disk which gave me a -9972 error. I tried Disk Warrior, but couldn't get it to boot. Is my hard drive done? I can't find an explanation for the code.
Read the following carefully. There are several suggested solutions that may or may not work:
How to Deal with a -9972 Error
Contributed by Fumiaki Kawashima
The error message, "Error: The underlying task reported failure on exit (-9972)" is a serious filesystem error in the Mac OS X Core Foundation. The problem can also lead to other critical errors such as "Keys Out of Order," "Invalid node structure" and/or "Invalid sibling link." The causes and scenarios vary. Troubleshooting a solution may depend upon computer configuration and whether the -9972 error is accompanied by other critical errors. This issue can also lead up to a kernel panic. If the error occurs when an external FireWire device is connected, disconnect it until you verify the device's compatibility.
Symptoms:
In most cases, you are unable to restart from Mac OS X.
* A volume is grayed out or not mounted with or without a kernel panic.
* A folder with a flashing question mark may appear.
* A bad partition map may be reported.
* A target disk mode solution may not work.
* Most likely, Disk Utility, Norton Utilities, TechTool and DiskWarrior cannot fix the issues.
* The high level disk format (Standard format) may unable to perform.
* You may unable to re-initialize the hard drive.
* A disk physically malfunctions in the worst case.
Example of an accompanied error message:
DiskWarrior normally fixes 1 to 6, but cannot fix errors 7 to 10 if the symptoms are very bad. There is no definite case.
01. Volume check failed
02. Invalid B-tree Header
03. Invalid map node
04. Invalid extents entry
05. Invalid clump size
06. Incorrect block count file
07. Invalid node structure
08. Overlapped extent allocation
09. Keys Out of Order
10. Invalid sibling link
Related documents:
What to Do When It Finds an Error
Technical overview of disk volume structures
Possible causes:
* Third-party FireWire device or enclosure, or other peripheral devices.
* Third-party mass storage drives or PCI card issues.
* Incompatible third-party kernel extensions.
* Mac OS X installer disc is improperly treated.
Solutions:
If possible and needed, back up data before troubleshooting. Methods (4) and (5) are for Power Mac desktop computers other than G5 models. The best bet is method (4) if you encounter multiple bad errors.
1. Unplug the power cord. Disconnect all third-party hardware except Apple keyboard and mouse before you start.
2. Do NOT re-install any third-party software/hardware until you completely solve the issue(s) and carefully investigate the compatibility with Mac OS X 10.3.x you install.
3. If another critical error "Invalid sibling link" is detected at any phases, disconnect and reconnect all internal power cords and data cables for hard drives and any ATAPI device. To do so, you may need to read the computer's CIP Instructions in advance. Normally, you do not need to remove third-party RAMs.
Method 1:
(1) Start up from Mac OS X 10.3.x Panther Full Install CD or DVD.
(2) Re-initialize and re-partition the hard drive. RECOMMENDATION: Select "Zero all data" option if "Invalid node structure" or "Keys Out of Order" error is detected.
If this method is of avail, go to Method 2 or greater.
Method 2:
(1) Start up in Mac OS 9.2.2 and shut down the computer.
(2) Start up from a copy of a Disk Warrior bootable CD for Mac OS 9.2.2.
(3) Run DW to fix the damage(s).
Method 3:
(1) Unplug the computer.
(2) Find a second ATA drive and jumper it as MASTER. Jumper the hard drive in question as SLAVE. Verify the jumper pin settings.
(3) Install Mac OS 9.2.x system on the MASTER drive, and update it to Mac OS 9.2.2.
(4) Start up from Mac OS 9.2.2. Re-initialize and re-partition the damaged hard drive with Drive Setup using the "Zero all data" option. Unplug the computer and reconfigure the jumper pin setting on the repaired drive for MASTER and the second drive for SLAVE.
(5) Restart from Mac OS X 10.3 Panther full install CD. Re-initialize and re-partition the repaired drive to install Mac OS X 10.3. Update to Mac OS X 10.3.7 via Software Update. Repair the disk permissions after each Mac OS X 10.3 installation and Mac OS X 10.3.7 update.
You may want to try starting up from Mac OS 9.2.x Full Install CD instead of from (2) to (4).
Method 4:
(1) Find a desktop computer that has an ATA controller PCI card (SCSI environment) and has two hard drive bays. This will make your damaged drive appear as a quasi-SCSI hard drive. Mac OS 9.2.2 must be pre-installed on the computer. I recommend a host computer that installs an Ultra DMA/xxx or xxx (ATA-x) interface equal to or better than the damaged drive with backwards compatible.
(2) Set the host computer's primary drive as MASTER and your damaged hard drive as SLAVE and install the damaged drive in the second drive bay of the host computer. Verify properly configured jumper pin settings in advance.
(3) Start up the host computer from Mac OS 9.2.2. Launch the "Drive Setup" utility. Re-initialize the damaged disk on the second drive using the "Low level format" option. It may take hours but less than "Zero all data" option. Note: Normally, a low level format with a quasi-SCSI drive takes much less (30 - 40%) time than an ATA configuration drive. Note that "Low level format" fixes all difficult logical damage.
(4) Put the fixed disk back in your computer's drive bay. Re-configure the jumper pin setting to MASTER before you place it into the drive bay of your computer.
(5) Restart from Mac OS X 10.3 Panther full install CD. Re-initialize and re-partition it to install Mac OS X 10.3. Update to Mac OS X 10.3.7 via Software Update. Repair the disk permissions after each Mac OS X 10.3 installation and Mac OS X 10.3.7 update.
Note that Panther's Disk Utility does not implement a "Low level format" option.
Method 5:
If Method 4 does not work or fix the damaged drive, let me know. You may need an advanced technique to fix it if the drive is physically not a problem.
OPTION:
Purchase a known good hard drive that conforms to your computer's ATA specification. Fix the damaged hard drive some other time. Nowadays, prices of hard drives are inexpensive.
