Mavericks install freezes with prohibitory sign and spinning wheel
I tried to update my MacMini from Lion to Mavericks. Everything went ok until after restart. On gray screen, Apple logo showed up for a while with spinning wheel which soon turned into prohibitory sign and spinning wheel. And this is where it stayed for hours and hours. Luckily I was able to recover back to Lion. I tried to update for another time but with exactly same results. Lion runs just fine with no problems but it would be nice to update if it is possible. Is anyone else out there having this same issue?
Welcome to Apple Support Communities
Did you check that all your apps are compatible with OS X Mavericks?
What I recommend you to do is to get a USB drive or DVD and copy the OS X Mavericks installer to it by using Lion Diskmaker > http://liondiskmaker.com Also, make a backup of your data with Time Machine.
Then, hold the Option (Alt) key while your computer is starting up and select your DVD or USB drive. Open Disk Utility, choose Macintosh HD in the sidebar and erase the drive, and finally, close Disk Utility and reinstall OS X. Disconnect all peripherals from your computer except the mouse, the keyboard and the USB drive or DVD, and see if OS X Mavericks is installed correctly.
After reinstalling Mavericks, you will be able to restore the backup you made

Just tried to update my iPad 2 to the current iOS, and I got an error that said the update wouldn't install. The iPad is stuck in a funny mode with the apple and spinning wheel showing. I can't power it down or restart it. What next? Thanks.
Try a hard reset: hold the power and home buttons simultaneously until the Apple logo appears.

My macbook pro doesn't boot beyond the grey screen with apple icon and spinning wheel. I used the "Option" button to access the Disk Utility function and run Repair Disk and Repair Disk Permissions. Should I restart my computer?
The following support article is somewhat outdated. Where it refers to booting from an installation disc, you should boot from your recovery partition (if running 10.7 or later) by holding down the key combination command-R at the chime.

Macbook Pro (2011) froze while working, forced shut down, now won't turn on. Grey screen with apple logo and spinning wheel for hours. Help?
Unfortunately do not know the operating system since I never updated anything and I can't get in to it.
Thanks for your assistance.If you want to preserve the data on the boot drive, and it's not already backed up, 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, you can skip this step.
There are several ways to back up a Mac that is not fully functional. You need an external hard drive to hold the backup data.
1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. 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. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
3. 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. -
start screen comes on with the apple and spinning wheel but underneath it there is a bar. Once the bar fills up my MacBook goes off what is that? What do I do?
Have you tried a safe start by holding the shift key when you boot? If that works, and it can take a while to complete, see if a regular boot now works. If it does, you need to free up space on your hard drive.
If a safe boot doesn't work, you need to either boot from an OS X DVD or go into target disk mode to connect via firewire cable to another mac to free up space on your hard drive. You need 5GB min, with 10% to 15%, or more, better, for systems usage. If you have a backup, move some data files to it, erase them and empty the trash. -

10.5.6 install fails with Prohibitory sign
Since the 10.5.6 update has come out, I've tried multiple times to upgrade to it. All fail after reboot with the Prohibitory sign (and the progress wheel below that still spinning).
I tried upgrading from 10.5.5 and then restored from my Time Capsule three times. I tried downloading the 10.5.6 combo update separately, same results. And after calling Apple support, who told me to rebuild the machine from the install disk, I tried from 10.5.1, same results. Apple support basically said "If you get that symbol and your disks are ok, then you're screwed." My disks are totally fine and the files are all there. Disks have been verified and permissions repaired. I've read through every possible failure scenario on every message board and have found nothing that helps. This is very frustrating.
Only two things I can think of that would contribute:
- I have a software RAID config with 2 drives, standard striped config
- I use Parallels 4.0
Any ideas? Thanks.wizrdry wrote:

Lose the RAID and lose the Parallels and see what happens. Install Leopard on a bare, clean machine. If it does not install, then call for a genius appointment. -
Macbook won't boot past grey screen with Apple logo and spinning wheel.
For some reason, after about 1 year and 10 months of owning my Macbook, it decided this morning not to load past the grey screen with the Apple logo and spinning cog/wheel.
I used it for a couple of hours beforehand, and it was working fine. Software Update prompted me of about about 4 or 5 updates; I can't remember exactly what was downloaded, but I think there was a Security Update and iTunes among them. I restarted, left it to install with no errors, but when I logged in, Safari and iTunes were running incredibly slowly. I also noticed that the volume keys weren't responding, as well as the power key to bring up the "Sleep, Restart, Shutdown, etc" dialog box. I forced shutdown, hoping a restart would solve my problem, and that's when my troubles started. I originally just left it, but after about an hour the wretched thing was still spinning.
So far, I have done a number of troubleshooting tips on a variety of websites. I have tried taking the battery out and holding down power for 5 seconds, resetting the PRAM with option, cmd, p & r, and holding down power until the sleep light flashes rapidly and the computer lets out a large "BOOOP".
I have booted off my Leopard install disk with both option and c, repaired the hard drive a number of times, with there being no errors whatsoever. I have tried repairing permissions, but everything seems to freeze up, except the mouse.
For some reason my computer will not boot into safe mode, either, and holding cmd & s at startup doesn't get me to the stage where I can enter commands with the keyboard.
Unfortunately, because of my puny 60GB hard drive, I only have 1GB of free space left and cannot reinstall Leopard without wiping my hard drive.
I would greatly appreciate it if anyone could assist me with this unfortunate dilemma. It's such a shame that my computer has been fantastic for so long and now decides to play up. (Maybe it's just Apple trying to get me to buy a new 2.4Ghz aluminium Macbook sooner than I was planning...)
Thanks very much.Hi ds,
Sorry to hear you're having such trouble!
Unfortunately, the best thing you can do at this point is reinstall Leopard (and then attempt to install the combo updater, too). If you don't have a backup of your machine, you could boot it into Target Disk Mode (by holding down T at startup) and then attach it via FireWire to another computer to salvage your files.
I recently had to repair a machine with this exact same problem, and after messing around with that for several hours, I'd have to say that I think that an Erase and Install is the way to go. If you then migrate over your user data and start having troubles, you at least know where the problem lies. I suspect, though, that having a clean machine with all of the new updates applied will be the end of the issue.
Sorry to be the bearer of bad news. There are a few other things you could try first; you could, for example, manually download the relevant combo updater from Apple's website and attempt to install it to your damaged machine while it's in Target Disk Mode. If you have a copy of Disk Warrior, that too is certainly worth a shot (and in some cases may be the saving grace). In my experience, though, a failure of this magnitude isn't easy to resolve.
Hope that helps.

MacBook pro 15" 2008 freezes at apple logo and spinning wheel
Have a MacBook pro early 2008 have installed lion but recently started to have problems. Started to freeze a lot so I would restart and most of the time it would work untill it froze again , now it's got worst every time I restart my Mac it won't go past apple logo and spinning wheel just freezes have been trying and trying but same thing freezes. Tried to start in save mode but no still freezes
Please has anyone got any suggestions thanksThe startup disk may need repairing.
Use Lion Recovery
Not enough free space on the startup disk can cause the system to freeze.
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space. -
IMac (early 2008): grey screen with Apple logo and spinning wheel
Hi there,
I have recently had a problem with my iMac - it started with distorted graphics and I booted into Safe Boot to back up all files with the intention of reinstalling OS X (either from original install CDs or from USB drive with Mountain Lion on). Safe Boot got rid of the distorted graphics but as I rebooted to reinstall, the iMac hung on the spinning wheel on a grey screen with the Apple logo.
I have tried (in no particular order) : resetting PRAM and SMC, booting from original install CDs, booting from the self-created Mountain Lion USB stick, booting into Safe Boot again, booting normally, taking out keyboard/mouse and booting normally... the pinwheel either freezes, the iMac reboots itself, or comes up with a screen telling me to reboot due to a problem. If I hold down command-V at startup it always freezes/fails at the same point and there's usually a previous shutdown cause of 3 or -128?!
I don't seem to be able to run the hardware test either from DVD or internet, I can boot into single user mode and the iMac will stay up for hours but I don't know what to look at or what to fix! There are kernel panic logs relating to some of the shutdowns but as I can't view these out of single-user mode I can't attach them to the post but can look & reply on another machine.
It's an early 2008 iMac, 24" screen, running OS X 10.8.2 - I'd appreciate any help and will try to provide any extra information anyone needs (that I can glean from single user mode, anyway!)
Kind regards,
CarlyI've looked at that, I did try to link the discussion to the article but it failed too Thank you though.
I just created an Ubuntu DVD to run - the graphics are distorted on that too so I'm guessing it's a fault with the graphics card. I don't have the knowledge to confirm/deny it so a trip to an Apple Store is probably in order? -
MacBookPro stuck on grey screen with Apple Logo and spinning wheel - help !
I was using my MBP when I dropped an empty folder into the trash and then went to empty the trash, suddenly everything went slow, i tried closing the windows and any applications but the beachball thing was spinning round on everything I was trying to close, I went to restart the computer the normal way (top left) but that had a spinning beachball so i switched it off with the power button. Now when it starts up it does the usual bong noise, shows the apple sign and the loadng circle but nothing happens after. I have tried the Pram reset thing but to no avail - I need help please !!
This typically means critical system files were damaged from the abnormal shutdown. It's possible that repairing the drive may fix the problem (but may not.) See the following:
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 and 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 (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) 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.
If this doesn't work then you will need to reinstall OS X. You may be able to do the following:
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.) 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, then quit DU and return to the installer.
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. -
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.

Imac hangs with apple logo and spinning wheel when warm
My imac seems to run just fine while it's up. However, after it's been on for a while and I reboot it (like when installing an update) it will get to a gray screen with the apple logo and a spinning wheel. After it has had time to sit awhile ( about 1/2 hour) it will start up just fine and run great until I have to do another reboot.
It will not even boot into safe mode until it cools down. I have reset the NVRAM, run the diagnostics on the hard drive (which showed no errors), swapped out the keyboard, disconnected evrything ( even tried without the keyboard), swapped memory and as a last resort wiped the disk and reinstalled the OS. None of this has helped.
At this point I am thinking that it is either a bad power supply or logic board. Is there a way to fully test each of these to determine which one is causing the problem. I do not have an extra of either that I can swap in temporarly to try and I do not want to spend the money buying something that I may not need. Neither one of those items are cheap.
Can anyone tell me how I can isolate which one it is? Is there a good program I can use to tell me this?
Any help and information would be greatly appreciated.
Thank you
Ray CApple is pretty specific about trouble shooting this, please carefully read and then methodically follow all the steps in the following article:

Good luck, however I think you have a hardware issue that will require your taking it into an Apple Store or AASP to be professionaly diagnosed. -

My MacBook Pro is stuck on grey loading screen with apple logo and spinning wheel.
PLEASE HELP - Tried to start up my MacBook Pro and I get grey screen w/ apple logo & spinning wheel. It's stuck on this screen. Safe mode didn't help but reveled this: smc read key action error, BOOS key failed, BOPS key failed. Consider rebuild of prelinked kernal com.apple.kext triggers triggered rebuild. IOBluetooth host controller USB transport Suspend Device. I ran verifications/repairs in Disk Utilities, but nothing came back wrong on the reports. I'm a bit panicked, as I use this computer for work and have no other computer to use in the meantime. I should also note that I have very little technical knowledge, so if you can lend your help please keep that in mind when responding. I'd be over the moon if anyone can help.
