My 2008 iMac will get to the white boot up screen and has the loading circle and then it will freeze. And will freeze when attempting to boot recovery or bootable disc of Mavericks
Hi there, I have a 2008 iMac 24' 3.06 Intel Duo with 4gb ram. And yesterday it was working totally fine and jolly with no issues. Then I noticed there was an OS X update for Mavericks, so I finally decided to do it, and once it was rebooted it went to like the grey screen and I could move my mouse, just nothing else was there. So I tried to restart it, and then it booted up, but was really laggy, and so I decided to restart it and try again, this time the iMac froze at the login. So I decided to take it apart, pull the 500gb hard drive, connect it to my MacBook Pro, and then formatted it in Disc Utility. From there, I opened the Mavericks installer on my MacBook and then installed it to the iMac's hard drive via usb hard drive enclosement. And once the install of Mavericks was completed, I put the hard drive back into the iMac and tried to boot it. It now boots up to the white screen with the Apple and the loading circle underneath the Apple and then it freezes and doesn't go any further. So then once that happened, I turned it off and tried to boot it into recovery mode. Then it freezes on the screen with the Apple and loading circle below it. Then out of desperation, tried to use a bootable disc of Mavericks to see if i can at least get the iMac to boot up again, with no success. It froze at the same point again. So now I reach out to the Apple Community to see if anyone else has an idea on what I can do or if anyone had this issue and what they did to resolve it. Any help would be great. Thanks.
mddcfilms and Pat75, I'm having precisely this same issue -- no booting but spinning and freezing gear under the Apple logo. Have either of you come to a resolution? Here are my details:
iMac, Early 2008, 24”, 3.06 GHz, 4GB
September 2013: Nvidia GeForce 8800 GS GPU repaired, HDD replaced with Western Digital 2TB
21 April 2014: Erased HDD with Disk Utility on Mavericks USB; clean installation of Mavericks from the USB. Process completed without issue, including registration process. After a minute or two of poking around, machine shut down immediately (not through the shut-down process).
Since then it will not boot up. Grey screen and Apple logo appear, with gear spinning; the gear freezes, then the machine tries to boot up again. Occasionally I’ll hear “To use English for the main language, press the return key.”
I’ve tried booting into Safe Mode; same gear freeze and restart.
I’ve tried booting to the 10.9 Recovery disk; same gear freeze and restart.
Tried booting from Mavericks USB; same freeze and restart.
Tried booting from 10.6.3 DVD; same freeze and restart.
Ran Apple Service Toolkit (at Stormfront in the UK), which turned up nothing in error.
Started in single-user mode to test HDD and RAM, which are fine.
Started in verbose mode to check logs; some error messages but nothing seems crucial. After the log screen, the grey screen and Apple logo appear, gear spins, and then freeze.
Cannot get to Apple Hardware Test (vintage machine too old?)
Cannot get to Target Disk Mode with my MacBook Pro
Ideas: Potential booting flaw in Mavericks installation. Firmware incompatibility with Mavericks. Hardware issue in Nvidia GPU (known for problems). At the moment I'm hoping that it's a Mavericks installation or firmware issue, though I suspect the Nvidia GPU has blown up on me. These graphics cards are known for being pieces of junk, so I may try installing the lower spec ATI Radeon 2600 GPU if I can find one at a reasonable price.
Anybody else have precisely these problems or have any advice?

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. -
My local apple store is in Belfast, Northern Ireland. Do you reckon if I trade in my iPod touch 4g black (less than I year old) I will get a new white iPod touch for free??
Please Post !!!!!!!!No, Apple does not offer that kind of exchange.
If you had a valid problem covered under the Warranty or AppleCare, they would swap it out for an identical item (including same color). -
I updated my IOS on my iPhone 4S and it locked up. I had to restore my phone and now iTunes will not go past the setup your phone screen even though the phone as been restored. How do I get iTunes to go past this screen so I can sync my phone again?
Depending on what iPhone you have when you get to the connect to wifi you should be able to activate your device over cellular data. Try doing a hard reset by holding the home circle button an power button until an apple pops up and the go through the setup again and when you get to the wifi part a option should be setup with cellular data iPhone 4 and above should give this option sometimes doesn't like showing up that's why u have to do a hard reset first

My iPad 2 will not allow me to update my apps. When I hit the update button I get a spinning circle but then it times out and doesn't update. In the past when I have updated successfully, the spinning circle would show me an indicator of time left on the update. I no longer have this Indicator. The circle just spins and times out and nothing happens. I've reset the iPad in the settings menu, reset the router, logged in and out of Apple id, powered ithe iPad off and on, and tried a couple other "fixes" that I've read online. So far no luck. AAny help would be greatly appreciated. Much thanks!
How much free space do you have? If it is low, installers may not be able to run properly.

Yosemite Upgrade - iMac mid-2011 - Stuck on white progress bar screen at about 50%
I have a mid 2011 iMac. I started the upgrade to Yosemite about 4 hours ago. For the last 3 and 1/2 hours it's been "stuck" at the white progress bar screen at about 50%. I hear the harddrive occasionally do reading/writing, but it isn't doing a lot just a tiny bit. I've seen others post across the net with similar situations, but no solutions. I'm willing to wait, but would love to know if it's actually proceeding or simply in some infinite loop.
Anyone know how to tell if it's in a loop or proceeding?
Anyone have any ideas on things to try?
I really don't want to try and interrupt the upgrade, but it doesn't appear it's going to complete.
Ideas?
Thanks for any help you all can provide.
PerryThis worked for my MBP 17" mid-2010 after 10 hours of minor panic watching progress bar stuck at 50%:
Reboot and hold SHIFT key to go into Safe Mode and keep holding that SHIFT key.
*Patience is the key to the Shift key*
Keep the Shift key down.
Do not let go of Shift key until you go to Italy when the computer does its Venetian blinds thing and goes into Safe Mode.
Check whether you have any login items. Do this via via Sys Preferences > Users & Groups
It is going to be slow. You are in SafeMode.
Remove any login apps.
Run any updates for Yosemite (e.g. Pages, Numbers, Keynote) within Safe Mode.
Reboot.
Remember, YMMV -
I am getting error (-1) while updating my iPhone 4 to iOS 5.1. The phone has gone into a recovery mode. Restore fails every time at "restoring the firmware" stage. Striped bar remains for a long time, then shows "error (-1)" and the restore fails. I have been doing it for last 12 hours. Help!
Thanks for your reply Michalo. I am in India and here Apple care does not work on Sundays. I have been without my phone for the entire day. Perhaps tomorrow will bring some respite. There is not solution to "error (-1)" on any forum it seems. I found one forum which suggested use of Tiny Umbrella. Any idea about that?

My MacBook Pro will not start. When I started it goes to a gray screen with the Apple logo and has the spinning dial. When I started in safe mode it will not start. In safe mode it as an error message that says MacBook Launch_msg(): Socket is not connected
If running 10.7 or later hold down Command-R at Startup.
This should invoke recovery Mode.
Choose Disk Utility.
Select your Hard drive. Inspect the SMART Status in the lower right of the window for "Verified".
Select the Mac OS X Volume (originally Macintosh HD) click (Repair Disk)
If errors, run again until it comes clean or gets stuck.
Report any error messages. -
When I charge my ipod, the apple symbol comes up as if it was turning on, then it goes black and repeats the process. Sometimes it gets to where I have to put in my 4 digit code to unlock it then goes black, any suggestions on why it does this?
Does it work OK otherwise?
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Try another cable and USB port and/or charging source
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

you may have a strong wifi signal but what kind of speed are you getting,
are you able to connect to wifi and see if it goes any faster then?
it might just be that the cellular data connection is slow
