Upgrading 4 different macs - 10.8.2 - ALL 4 hangs with apple logo but before spinning wheel

Crazy! Never happened to me EVER, not even close and I've been using and administrating macs since 89. Upgraded all my macs, incl the MBP of my nephew; MBP Retina, MacBook Unibody (hybriddisk), MBP 17" + Mac Mini (thunderbolt) ALL ultimately needed reformating drive and fresh install to get up & running again, hours of extra work! All identical freeze displaying apple logo but no spinning wheel. Could start all in recover mode but could not from there remedy whatever fault there was. 3 of the macs more or less (Retina & MacBook) identical equipped software-wise but MBP 17" very sparse software (belonging to computer-"illiterate" so no fancy software. The latter had Lion so in that case as opposed th eother macs this wasn't an incremental 10.8.1->10.8.2 upgrade.
I have upgraded all macs fresh via internet so no upgrade via downloaded install file on for ex usb-unit.
Any ideas?? I'm really frustrated and disappointed, this cannot be a freak occurence!

I have no helpful reply to give you except moral support: I'm having the exact same problem (going from 10.6.8 to 10.8.2 on a 2010 MacBook Pro.) I have tried reboots, reloads, disk repair, permission repair (between each attempt I reloaded from a clone). Also tried loading it, then repairing from Recovery mode, then restarting. Endless spinning wheel at the Apple logo as 10.8.2 attempts its first startup every time.

Mac book air stuck on grey screen with apple logo and spinning wheel

I had a lot of tabs open and several applications as well. things really slowed up when I added El media player to the mix. finally computer froze completely and now can't get it to restart (stuck on grey screen) tried SMR plus PRAM procedures without success.

Hmm... try doing this:
1) Force your Mac to shut down by pressing and holding the power button for about 5 sec.
2) Start in Safe Mode. Press the power button to turn it on, and before you hear the Startup "Dummmmm" chime, hold down the Shift key. For a few sec, you won't see the Apple logo. Keep pressing the Shift key until you see it. If you press it after the Apple logo appears, start from Step 1 again.
3) This time, your Mac should take longer to boot. (Like a minute or 2 longer as it is going thru the necessary files to boot from, and not just everything like in Normal Startup mode; which caused it to hang)
4) Does your Mac boot sucessfully to the Login Screen or Desktop? The login Screen should show SAFE MODE in red at the top. The Desktop should have Sound disabled and seems a lot slower. If you see either of these, backup ALL your files (if you have not already done so) on to an External HDD. Create a new User Account in System Preferences>Accounts with about the same info as your current account (The name will have to be different though, if your previous account was John, this time, add your last name as in John Appleseed.) Make sure it is an Admin account. Then, login into the new account and delete your previous account. Copy all your files over to your new account and restart your Mac correctly by going to Apple Menu>Restart.
5) This time, don't press anything and let it boot normally. Does your Mac boot correctly? I hope that helps you a little. Get back to me if it does not work!

My Macbook will not boot the operating system. It just goes to a blue screen after the apple logo and the spinning wheel goes off. I took the battery out and held the on/off button for five seconds and reset the PRAM. I have the old mac os disk.

Thanks

You won't lose any data unless you erase your hard drive.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c"key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it.When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've selected the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.

Panther won´t boot at all, Grey screen with apple logo

Help, I installed a Lexmark 1420 this afternoon and printed what I wanted and switched off! that was the last time my emac booted. I only now get they grey Apple logo on the screen, I´ve already tried pram reset, boot with x with shift even the software restore cd won´t read(but I can open the cd draw with the mouse held down.) I been looking through the messages and still can´t find any answers, would be really greatful for some help.

Stuart:
Sorry about the glitch. That Disk Utility reports "Underlying task reported failure" when repairing a volume is a serious directory issue that can sometimes be repaired by Disk Warrior.
In terms of getting you data off the HDD to the external Firewire HDD, here are two options.
1. You can use SuperDuper to create a bootable clone of your entire HDD on the external firewire HDD.
2. You can purchase DataRescue II to get your music off. I understand Prosoft has excellent tech support. Give them a call. See also Dr. Smoke's FAQ Data Recovery.
Please keep us updated.
Good luck.

I have a mac book pro 2010 and when i turn it on i get the gray apple logo and a spinning wheel.

it acts like it's going to download, but gets halfway through and turns back off. i've tried to put it in safe mode by holding the shift button down, but it wont do anything..

Use the original installation disk and get into Disk Utility.
Insert the DVD in your MBP as if you will be installing the OSX.
When you get to a display where there is a menu bar on top, click on UTILITIES.
From the drop down menu, select Disk Utility.
Op[en Disk Utility.First Aid and run Verify and Repair.

After installing the latest update for Mavericks and restarting, my Mac just displays the Apple logo and the spinning wheel. What can I do to fix this?

I installed the latest update of Mavericks from the App Store today and after restarting my system it doesn't go beyond the Apple logo and the spinning wheel. I tried resetting the NVRAM but it still has the same problem.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
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 a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
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 in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is 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.

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.
Before reconnecting 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 above for instructions.) 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 produces. Look for the line "Permissions repaired successfully" 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.

Restart your MBP holding the trackpad down and hopefully the disk will be ejected. Then try to return it and get a refund or put it in the trash. There is nothing that software does for your MBP that you cannot do yourself or with free software.
If can get your MBP started, delete all traces of the offending software. Worst case is that you may have to erase the HDD and reload the OS and your user data. I trust that you have a backup (minus MacTuneUp).
Courcoul has given you his opinion in a very succinct manner, and as you might surmise, I agree with him.

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

I just downloaded IOS 8 on my Iphone 5 and to do so i had to delete all my photos to clear space, but before so I selected all of them and copied them. The only place I can seem to be able to paste and see them is while making a new message in gmail and then when i tried to send them the message comes back blank and looks like below. what can i do to retrieve them?
<Edited by Host>

As razmee209 said, you can use iTunes to install photos on your phone from wherever you have them stored. Where did you copy them to? Are you saying you selected them on you phone and just hit "copy"? That would only copy one at a time to the "clipboard" so that you can paste it somewhere else. As you copy each one, the previous one is deleted from the clipboard. This is not a storage area. Did you back them up on your computer or in iCloud?
