My iMac is stuck with a grey screen with a icon of a lock.

You enter Target Disk mode by launching the iMac with the "T" key held down or by the method you used. It's used so another Mac connected to it can access the files as if it were another external HD. This document describes the process: Target Disk Mode, Transferring files between two computers using FireWire

Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Leopard - This will install a "fresh" copy Leopard without archiving old system files but leaves the rest of your files in place.
If you still want to restore your computer to factory level...
Start up from your install disc, go to Disk Utility and select the disk and click erase - to securely erase data click Security Options and Erase Free Space which will entirely wipe your disk, overwriting it with zeros so that no data is recoverable.
To restore read the instructions in the Mac OS X v10.5 Leopard - Installation and Setup Guide PDF

If you have a G5 then it's a PPC (Power PC) based iMac, this is an Intel iMac forum. Try the Gray screen appears during startup link for troubleshooting steps. I suspect the HD has crashed.

Computer crashed and is stuck on a grey screen with the apple logo and pinwheel turning
Please help

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
     a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Imac G5 stuck on white loading screen with gray apple and spinning wheel

I purchased this imac from a rebutable seller on ebay. He obviously had it working before he sent it to me, and he has been helpfull the whole way through, so I am positive this computer is not junk. When I recieved it, I plugged it in and turned it on, at first nothing would show up on the screen and the fans came on. Then, I contacted the seller and he told me to hold the shift key while turning it on. That did work to some extent. Now when I turn it on, it is stuck on the white screen with the gray apple and the spinning wheel. He had just updated and installed EVERYTHING imaginable so I am positive everything is up to date. I am not sure what to do, I have researched this but I cannot seem to find an answer. Oh, and even know on the white screen the fans turn on. It is quite weird.
Well, I hope someone can help. Thank you.

Call AppleCare. You should not be having problems with a brand-new machine.

My Mac book pro turns on with a grey screen with a blinking folder question mark. Help!

My bag carrying my computer fell on the ground as I was entering a cab. I checked my computer immediately for damage and it seemed to work fine. After about an two hours, I went back to my computer and it had a black screen and was getting very hot. I held the power button down and it restarted only to have a grey screen with a blinking folder + a question mark. I've already looked on the forums, and I don't have the CDs with me as I am traveling, and I don't have much backed up.
I appreciate any advice provided.
Thank you!

When I restart my iMac it is stuck in the grey screen with spinning circle

When I restart my imac (less than 1 year old) it won't start up. I get the grey screen and spinning circle and it never moves beyond. A few times in the past, I've tried to reset the PRAM and that has worked. However, its not working this time. Nothing seems to restart the computer.

Hi,
The Recovery HD I believe is the Internet Recovery feature found in most 2010 and 2011 Macs. Another poster in this topic suggested taking a look at an Apple support article regarding this issue. A solution may be found there that may work for you. If all else fails, I'd recommend you contact AppleCare. Unless you are within 90 days of your purchase (which isn't the case for you) you'll either need to have the AppleCare Protection Plan to call AppleCare over the phone, otherwise I'd suggest taking your iMac to an Apple Retail Store. Could be inconvenient doing that, though, considering the iMac is not exactly portable. However, the Apple technician will (presumably - just guessing) do various initial hardware tests on the machine and hopefully resolve the issue for you.
By the way, the Internet Recovery feature (Recovery HD) allows you to restore Mac OS X in the event you have misplaced your installation discs, for example. The Internet Recovery feature can also be activated at boot up by pressing the Command (Cmd) key and the R key afterwards (while keeping the Cmd key pressed down).

I updated my MacBook Pro, and now it's to fully restarting.. It's stuck on the grey screen with the loading sign at the bottom of the apple.

How do I fix this issue???

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

I think my HDD is dead - stuck at the grey screen, with the apple logo ..

Hi all,
I think my Mbp's HDD has partially failed. It is the original 100gig drive , which was 95% full.
It started getting incredibly slow so I decided to reboot it. It has not been possible to boot.
I have managed to connect the internal drive to another mac using FireWire and T on startup.
The drive shows up and the data can be accessed albeit slowly.
I tried to repair the drive in disk utility and it came up with a lot of " invalid node structures" and " invalid record counts".
The disk utility seemed to not complete the process so I had to quit it.
I can't boot from the cd , but I may be doing it wrong.
Can anyone help me with the next thing to try?
Thanks.

Slow access even with Target Disk Mode (TDM) can indicate a failing drive, but it's possible that drive can be rehabilitated by continuing to off-load files and keep trying with Disk Utility. Sometimes, enough DU runs can restore sanity.
I'd check the SMART status first (try: SMART Utility at Apple OSX Downloads ). This can be done from the other Mac while the MBP is in TDM. If the drive passes and you can off-load some of the load, then a directory repair utility like DiskWarrior might be worth a try.
However DiskWarrior is US$100 and you can get a new 500GB SATA 2.5" hard drive for less than that. The advantage to disk Warrior is that it's easier to install in an MBP than a new hard drive.

Old iMac won't start up and stuck in grey screen with spinning wheel

Hi, I have a very old imac which I purchased back in 2005, and has been working fine. I have left it in storage about 1 and 1/2 years ago.
Just now I try to restart it, the screen is forever stuck in the grey screen with the spinning wheel.
I tried many times off-on, hold down the apple function key but none worked.
I no longer have the rebooting CD with me. I wonder whether the computer can still be saved?
I have already backed up the contents so it doesn't matter if fixing the computer requires me to delete all my old files.
Thanks
If I am not wrong, I think it's tiger or earlier that it's using.

Do you have the Install Disc to try to boot from?
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...
