Macbook Pro (A1278) - Unable to startup - stucks at Apple logo with spinning wheel.

My friend gave me his macbook pro today having startup issue. It stucks on apple logo at startup with a spinning wheel.
I have tried to repair disk but does not work.
tried to reinstall OS but it says This Apple ID is not the one which you used to purchase this OS version (something like that)
I upgraded from mac os x lion to mountain lion.
I do not have any installation media as well.

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 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.”
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. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
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. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
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.
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
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.
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
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
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.

Macbook pro won't startup. Stuck on apple logo with spinning wheel.

When I start up my 15 inch Macbook pro, it gets to the apple logo screen with the spinning gear underneath and it just stays there and does not startup. I have let it sit that way for up to an hour and it juts stays on that screen. Please help!

Awhile ago I updated my Macbook Pro to Mac OS X Lion, am I able to transfer this to my iMac as well? Or do i have to buy the whole thing over again on my iMac?

You need to upgrade the iMac to Mac OS X 10.6.3 and then 10.6.8; the installer won't run on 10.5.8, and it won't install onto a 10.5.8 system if run from a compatible OS.

Mac OS X: Gray screen appears during startup

I Mac won't start -- we get apple logo with spinning wheel, question mark that disappears and then a blank blue screen

My daughter's old I Mac won't start. It is not backed up. We want to get some things off of it if we can.
When we turn it on, we get the Apple logo with spinning wheel for awhile, then a question mark briefly and then a sky blue blank screen. Is there any hope of getting this to work? This computer is out of warranty. Does it seem that if we reinstall the Operating System we might find old data?

First try restarting with the original install disc an run Disk Utility to repair the drive. If you have to re install the OS make sure you select archive and install or else everything will be lost.

Please help me! MacBook Pro stuck on apple logo and spinning wheel

Hi I'm really desperate and need help! My MacBook just stopped loading and would stay on the gray screen with the apple logo and spinning wheel.
I have tried safe mode and it would load a little and stop and then the loading bar would be blank and it would stay like that forever!!
I also have tried doing the single user mode and when I type the fsck - fy it will do a couple more lines then it will say error like a hundred times :(
I did verbose mode and it would just give me stuff that I have no idea what it saying I left on verbose mode for like 5 hours and it would just give me lines of stuff I have no idea what it's saying!
I downloaded lion through apple store so I don't have the disk I only have my snow leopard disk
Please please someone tell me a solution it's my moms laptop and I don't want to get in trouble!

Reboot in recovery mode an possibly repair over the internet.
Command-R to the rescue.
Just hold down Command-R during startup and OS X Recovery springs into action. It lets you choose from common utilities: You can run Disk Utility to check or repair your hard drive, erase your hard drive and reinstall a fresh copy of OS X, or restore your Mac from a Time Machine backup. You can even use Safari to get help from Apple Support online. And if OS X Recovery encounters problems, it will automatically connect to Apple over the Internet.

Macbook pro will not boot, gets stuck on great apple logo with spinning wheel.

I have a Macbook Pro A1287 13" Core2Duo Intel running Mavericks. This morning it would not boot and got stuck at the grey apple logo with the spinning wheel. I have tried:
1. Resetting PRAM
2. Resetting SMC
3. Starting in Safe Mode
4. Boting to recovery partition and verifiying and repairing both disc and permissions
Unfortunately none of these have worked.
I thought after reading other discussions that it may be the sign/start of hard drive failure and that the hard drive may be corrupt.
The strange thing is that I swapped the hard drive with another macbook pro that I use in work and it boots to the HD no problem, all my files and desktop are as expected.
So, I thought this must be a hardware issue, maybe something to do with the hard drive cable, the battery or worse the main board, but when I put my work macbook hard drive in my macbook it also boots. Other than swapping the machines, I'm not really sure what to do.
One thing to note is that I have noticed over the past few months that the clock will have re-set when booting up and that occasionally the machine will turn off with no warning and reboot.
I would have thought if it was a hard drive problem, the drive would not boot in any machine, and if it were a hardware problem then the machine would not boot with different drive in it.
Any ideas, would be appreciated.

Thanks Linc for the swift answer. From what I have read on this discussion board and from other sources the model of Macbook I have does not have a logic-board battery, but may have a soldered on capacitor.
Also, would this not cause the other drive I tried in the laptop to fail to boot also, as I said in my original post, the machine works ok with a boot drive from my work macbook pro. Just trying to eliminate all possible causes before taking it in somewhere to be looked at by a technician.

Macbook Pro Stuck at Apple Logo and Spinning Wheel

I Have ML. Just did the most recent update. There seemed to be a bundled group of updates. Once all was updated, my computer froze. I shutdown and restarted and it was stuck on the Apple Logo and spinning wheel. I have tried everything. Safe Mode, Command R, Command/Alt/R/P....it does nothing. Any advice out there?

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Apple logo with spinning wheel in Mac OS X 10.8.5

I have a 15 inch MacBook Pro with 4GB ram and 2.4 GHz Intel i5 and OS X 10.8.5 and everytime i boot up it gives an apple logo with the spinning wheel, after 3 or 4 boot try, it actualy boots normaly to mac os x normaly. I already repaired the permissions, reseted the PRAM, and still no use.
I often use heavy programs like Final Cut Pro 7 (.0.3), Firefox, EyeTV, and Soundtrack Pro.

I already done this way and still no due
here's a list of things i've already done:
- Reset the PRAM
- Uninstalled some programs i didn't use, like the older versions of iLife, iWork and MS Office for Mac
- Repaired permissions
- Uninstalled most third-party content i didnt use, like the black barry files.
I also did a full backup and a full reinstall of the OS and software I used most such as the latest version of Adobe's CS6, and Sun Office suite and the MS Office for Mac, and the Final Cut Pro X suite and Final Cut Pro 7 suite.

Mac won't boot: stuck on apple logo and spinning wheel

My MacBook pro 13 inch(mid 2010) won't boot. It just gets stuck on the apple logo with the spinning wheel under it. I have done the following but they have not solved the issue:
Zap pram
Attempt to boot in safe mode
Try to access windows partition( resulted in flashing folder with question mark)
I am dying to try to insert the Mac os x install disc and use disk utility, but it is not going into the drive. This all started when I had to turn off my Mac because it had completely froze. Any help would be greatly appreciated, especially if there is a way to insert the install disk.
Thanks in advance for any assistance.

Try this:
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
If you have a problem with the above, then try:
1. Restart the computer.
2. Immediately after the chime press and hold down the "OPTION" key.
3. Wait for the boot manager screen to appear, then insert the installer disc into the optical drive.
4. Wait until the disc is recognized and appears in the boot manager screen.
5. After the disc appears select it then click on the downward pointing arrow button.
5. Wait for installer to finish loading.
If you are running Snow Leopard, then reinstall it. Your HDD will not be erased, and all your data will be preserved.
If you are running Leopard then do this:
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.

2007 MacBook Pro w/ Mac OS X Lion Can't Automatically Connect to my Wi-Fi Network...

Hello everyone,
I have a late 2007 15" MacBook Pro (not Unibody model) that has been recently upgraded to Mac OS X Lion (not Mountain Lion).
Ever since the upgrade, when I power it on, everything loads as it should but what I notice is that my MacBook doesn't automatically connect (or finds) my wireless router. I have to click on the wi-fi antenna icon on the top right hand corner, and manually select my Wi-Fi connection from the pull down list. What's even more bizaare is that my MacBook knows to automatically connect because it's in my preferred network list.
I also have a 27" iMac with Mac OS X Lion and I don't get this issue. It simply powers up and automatically connects to my wireless network. I tried to compare configuration settings on both my MacBook and iMac but everything appears to match.
All of my software updates are up to date.
I really hate powering on my MacBook and manually select it from the pull down list of available networks.
Any help? Suggestions? I'm really scratching my head on this one.
Thanks!

Things to do on the affected MBP.
Switch off WiFi
In System Preferences, Network, WiFi interface, Advanced - remove the problematic network.
Go to Keychain, (Applications, Utilities) and remove keys associated with that network.
Switch on WiFi and try to connect again.
Please report back.

My MacBook Pro pwers up but does not get past the the Apple logo.

I have a MacBook Pro with Mountain Lion. It powers up but does not get past the Apple logo. The hardware test did not reveal any problems. It will also not get any further when I try to start up in Safe Mode. The last thing I was trying to do was connect to it from my desktop which I have done before. Any ideas.

I was able to get into the Repair utility and resolved some Permissions problems. It verified the disk and found no problems. However, it did not resolve the issue. I was also not able to get into Safe Mode.

Macbook 2008. Did an erase and install from install disk that came with the mac but now it won't move pas the Apple logo with spinner.

My Macbook was running slow and kept giving me error codes so I figured the easiest thing to do would be to erase it and do a fresh install. But now, after installing with the disk 1, it won't move past the grey Apple logo screen.
I've done disk repair and verified and there seems to be no problems.
Any suggestions?
thanks
