IMac Mini stays at Apple logo screen.

I clicked on something to drag it into the trash. I was asked my password. I put it in. I shut down my computer.
Now my computer is stuck at the Apple logo screen--nothing, no spinning wheel, just a white screen with the Apple logo.
Please help.

Hi Vince,
Do you remember what exactly you put into the trash bin?

IMac G4 hangs at apple logo screen after 10.5.8 update

Hello, thanks for any help you can provide with this problem.
Machine is iMac G4 flat panel. Did an erase and install of Leopard over firewire from iMac G5. Immediately copied 10.5.8 combo update I'd downloaded earlier from the G5 and ran it on the G4. The update completed successfully, albeit slowly, and I clicked restart. After a long wait at blank desktop, machine rebooted on its own. It got as far as the Apple logo screen with spinner spinning, and then it hung. I didn't want to jump to conclusions that it was indeed frozen, so I let it sit there and spin for at least 2 hours. Even for an old G4 this seemed like a bit much, so I forced it to power off and tried again. Still hangs.
At this point I figure something went wrong with the update, so I did another erase and install of virgin Leopard over firewire from the same G5. Repeated update process. It once again completed successfully, I clicked restart, it paused, then rebooted on its own again. To my great dismay, it once again hung at the spinny spinner Apple logo screen.
Now, this is the fourth G4 machine I've done this on in the last week, and the other three are running normally. 1 was another iMac G4, the other 2 were eMac G4's.
Any suggestions?

Interestingly, I brought the G4 into work today and connected it to the G5 with FireWire and turned both on. For some reason (I'm not Mac Pro here, so this might be obvious to some of you) the G5 booted from the G4's HDD and the system started up just fine. I ran repair permissions on the G4's HDD and restarted it. It now boots up fine. Not sure if it was the repairing permissions that fixed it or booting the OS on a different machine. Either way, problem is resolved. Thanks for your input.
Edit: Fixed typo

Imac 5k stuck on apple logo screen after latest update

Hi - i have a magazine deadline and a major issue:
i've been having loads of kernel panics (see thread here Brand new imac 5k kernel panic) and having seen there was a new update figured it would be worth installing it to see if it fixed them as nothing so far suggested by apple support has helped. Once it had downloaded the update the OS said it needed to reboot to finish installation. It got half way through the loading bar on the apple logo screen and got stuck. I left it an hour, came back still nothing. Left it another hour and it was still just stuck half way. I rebooted into diagnostics and ran that and it said everything was fine but further reboots just get as far as halfway through the bar. I'm now stuck as the computer was only a month or so old and i hadn't yet set up back up on it. I was still in the process of getting everything configured and over from my old machine. Problem is I have a bunch of photos that were transferred on to it that i shot 2 weeks ago and I need them for a magazine deadline tomorrow and apple support options could only call me back on Thursday - if anyone can suggest anything i will be VERY grateful. I've already tried SMC and PRAM resets.

I did that, a fresh OS install and it worked for about 4 hours then i got a kernel panic

IMac sticking at the apple logo screen

I just turned on my 24 inch iMac it starts to boot, the music plays, the apple logo appears then the whirley wheel appears and the machine sticks with a blank grey screen. I have tried Turing it on and off. I tried plugging in a wired keyboard in place of the wireless keyboard and pressing keys at random, but no change.
The iMac is running Lion and has been updated. It's been behaving.
Anyone have any suggestions
Andrew

If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below to select it:
syslog -k Sender kernel -k Message CSeq "I/O error" | tail | open -f -a TextEdit
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the window will be empty. If you get output like this:
kernel[0] <Debug>: disk0s2: I/O error
the boot drive is failing, or there's some other hardware fault in the storage subsystem.

IMac stays on apple logo screen wheel spins for ever that's it

Tats all it does I can't get it to start up just the the apple start up logo and wheel spinning

Sounds like you have a problem with your internal disk. Try starting in Recovery Mode hold the command and R keys down while you restart the Mac and hold them til the Apple icon appears.
see OS X: About OS X Recovery for full directions.
If you can get into Recovery mode you can try to repair your disk using Disk Utility. If that fails you can re-install Mountain Lion

Boot from the original Install disc that came with the computer and then format the drive Mac OS Extended (Journaled) using the GUID partition. Then you can re-install OS X. If you no longer have the original media call AppleCare with the serial number of the machine (look on the bottom of the stand) and for a nominal fee they will ship you replacement media.
The chances are very good you will have fan problems if you used an off-the-shelf HD, beginning in 2009 Apple began using HD's from vendors that incorporated heat sensors into the HD. If you did not buy the same type of HD your computer will think the HD is overheating causing the fans to run at full speed.

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle. I have tried various commands but to no avail. does anybody have any advice?

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 11. 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 randomly frozen at grey Apple logo screen.

Hi Guys,
I need your help.
My iMac randomly freezes at startup, at the grey Apple logo screen... some vertical black bars appears, the image is unclear and doubled. The round icon showing that the system is loading freezes. Some times, a black screen appears asking for the computer to be restarted.
I need to power off the iMac for 7-8 times and then it comes to normal till the next boot.
One time, a month ago, the same happened when I was already in leopard, but since then nothing. Now, in the last week, it's happening in 80% of the startups.
Any idea?
Thanks !!!
Andrei

1. Have you installed any third party RAM? If so try removing the third party RAM and install the Apple original RAM for testing.
2. Disconnect all external devices during testing. This means hard drives, ipods, printers, scanners, and hubs.
3. Boot to your install disk. Insert the install disk and hold down the "c" key at startup. Once it boots up select your language but instead of going through the install process go to the Utilities menu at the top select Disk Utility. Select your hard drive/Mac volume on the left then under the First Aid tab click Repair Disk. If that passes/repairs successfully Repair the Disk Permissions. Once this is finished go back to the Utilities menu, select Startup disk, choose your Mac OS X volume and click restart.
4. If you are still having issues insert your original gray iMac install disk, restart and hold down the "d" key. This will boot you to the Apple Hardware Test. Run the Extended test.

My Powerpc Mac Mini froze up recently, having left it on for a few days without shutting down/resetting. I impatiently turned it off with the power button at the back. When I turned it on again, it only got as far as the grey apple logo screen, it now refuses to go past this screen despite numerous power resets, and unplugging at the power.
I have reset the PMU and the PRAM as suggested by the troubleshooting, to no avail - the PRAM did work as it changed the resolution of the apple logo, but still got stuck at the grey startup screen. Its out of warranty so I have to pay for technical support. Can anyone help?

If you have the original install disk that came with your mini, the first thing to do is to insert that, and then boot the system holding the C key down. This should force it to boot from the install disk rather than the internal drive. The reason you want to do this is two-fold: firstly that if it boots OK that way, it shows the basic hardware is OK, and secondly, it's possible that the hard drive has developed errors (likely directory damage) and the tool to check for that and attempt to resolve it is on the install disk.
Once you've got the system booted to the install disk, exit the installer and run the Disk Utility application. That should display the internal drive (and the install disk) on the left. Select the internal drive and then click 'Repair Disk'. If no errors are found, the drive is fine and the problem lies elsewhere. If errors are reported and the disk is fixed, then you should be able to reboot normally afterwards. If errors are found and Disk Utility reports 'error on exit' not having fixed them, then run it again just to be sure, but otherwise it means the drive is damaged sufficiently that Disk Utility can't fix it. A third-party application such as Alsoft's DiskWarrior will then be needed if you want to try and fix the drive and recover data, or you can simply elect to do an erase and install, meaning the drive will be reformatted and a new copy of MacOS installed. Do not do this if you have data you need to get off the drive!!

Ipad mini cycles from apple logo to start screen and wont stop

Ipad mini cycles from apple logo to start screen and wont stop. Will not shutdown. Cycles every 5-8 seconds. Thanks!

I'm having the same problem. Since it's the same problem, I thought I'd pigtail on this thread, rather than clutter up the forum with a duplicate. I can start a new thread if this is not appropriate.
I have tried a reset, using the sleep/wake and home buttons, with no success. I have also restored to factory settings, then restored to backup. It's still rebooting itself.
iPad Mini wifi (not Retina). iOS 7.1.1.
This problem started today. I updated to 7.1.1 soon after the update was released.

According to KB:
"Error 1611: This error may indicate a hardware issue with your device. Follow the steps in this article. Alsoattempt to restore while connected with a known-good 30-pin Dock Connector cable, computer, and network to isolate this issue to the device. The MAC address being missing or the IMEI being the default value (00 499901 064000 0) can also confirm a hardware issue. Out-of-date or incorrectly configured proxy or security software, such as FoxyProxy, can cause error 1611. To troubleshoot third-party security software, follow these steps."

My iPod touch got restarted and frozen on the apple logo screen after I erased all content and settings. And it got restarted and frozen again every 5-10 mins until low battery. It also doesn't recognize by iTunes. Did any one has the same problem? And how did you solve it? Thank you.

My 27inch iMac has been stuck on the Apple logo screen.

My 27inch iMac has been stuck on the Apple logo screen which the spinning wheel stuck for a few days now and I've tried everything. I've tried com s fsck repair, option boot from a dvd and still nothing please help.

Please be specific, saying "I've tried everything" doesn't tell us a thing. I'd recommend starting by using what Apple says in Gray screen appears during startup.

IPod nano will not connect and the Apple logo screen stays up

Hello,
Earlier today I shut my iPod nano off normally (by holding the pause/play button). Later, when I went to listen to it again, I found it wouldn't turn on. I tried resetting it, and I got the low-battery signal, so I plugged it in. The thing is, the Apple logo screen is illuminated and I cannot get it off that screen, and normally when I plug my iPod in, iTunes comes up. iTunes didn't come up and it says there is nothing plugged in. What should I do?

Okay.
If the Apple logo is not going away and the iPod won't get to the main menu (when not connected to the computer), try what those links suggest.
If your iPod does not get to the main menu or say Do Not Disconnect, it will not be recognized by the computer. You have to get the iPod to say Do Not Disconnect, show the main menu, or just get past the Apple logo before it will be recognized. The above links will help you get the iPod get past the Apple logo.
The iPod cannot be recognized by iTunes or the computer if it is stuck at the Apple logo.
Finally, don't connect the iPod while the iPod preferences in iTunes are open.
