Macbook Pro will not boot past apple logo/spinning gear

Earlier this evening I was installing the aperture 3.0.2 and iMovie 8.0.6 updates onto my MBP and the system refused to install the Aperture update so I decided to shut down and restart the mac and when I saw the familiar Apple logo spinning I was distraught to see it would go no further. I then did what ay learned apple user would do and reset the PRAM and let it chime 4 times, just to be safe, and I restarted holding shift - the grey bar finished but it still would not load. I luckily have a Carbon Copy Clone of an old hard drive for this machine before I upgraded (much too outdated to copy back over - I would lose Final Cut Studio 3 and Aperture 3 etc...) which I was successful in booting into (and am using now) to do a disk utility > repair permission and repair disk. Both had no errors and I was sincerely confused. I attempted to boot it once more before I started to freak out. Needless to say I freaked out. I booted in single user mode and ran the checkdisk within that TWICE before typing exit and it did the rest of the verbose boot which then hung on "AirPort: RSN handshake complete on en1" This is the end of what I know to do - so with that I hand it off to you... any help is appreciated a and will definitely be attempted.

The drive had over 350GB available. Yes I suppose I would be able to but I am unable to locate one. If someone is certain a OS replacement install would fix things I am willing to go buy one...

Imac will not boot past Apple Logo

My imac will not boot after the good chime and apple logo (i don't even get a spinning wheel). I have held the option key down and selected the OS 10.6 disk with the same result. I was able to erase the drive and reinstall OS 10.6 using target mode and another computer. In target mode I can boot the other computer from the IMac HD but not the IMac. Have also tried holding the shift key and booting into safe mode with the same result. Additional note: I reset the PRAM and the SMU. At first on PRAM reset it would take 45 seconds for the machine to chime again, after OS reinstall and SMU reset, PRAM reset chimes within 10 seconds.... any help would be appreciated...

Kind of late but your solution helped me remember what once worked for me, a few years back.
Started iMAC in Target mode Used a firewire cable to a MacBook Pro
Started the Macbook Pro using the option Key and then restarted with the iMac as the Hard drive
Then I updated to 10.6.8 and allof the other updates.
shut down and rebooted and everything was fine.
But first I did quite a few other things before the update such as
It all started with a DiskWarrior finding overlapped files, I have been around the block a time or two so after it found three overlapped files, I shut down diskwarrior started up disk utility did a restore of the messed up drive to another external drive,
of course this copied overlapped files and all to the new external drive It took 24 huors or so, to back up the drive once it was done, I also tried a few times to correct the overlapped files to no avail,
so then I started the iMac up in target mode used the MacBook to format and erase the original drive, used the 10.6.3 DVD installer to install onto the hard drive, using the macBook DVD. After I was finished with the install to the iMAC,,,,,,,,,,this is where I got the three beeps like bad ram So idid the PRAM and SMC to no avail.
The operating system was evidently not new enough so once I did what i said at the begining of this post all went well.
Sometimes It is tough to remember some of the stuff that you learned several years ago.
and tired hard to forget.
I hoped this post does not scare away to many people, I was just about done with this computer until I read your post, one of several dozen, and it all came back to me.
Thanks a Bunch
I hope this can help others

MacBook Pro Will Not Boot Past Apple Loading Screen At All.

I am having a major problem with my MacBook Pro and it just wont boot past the apple loading screen at all
I have tryed al lot of ways to fix this and it just wont work
It does not go into safe mode, it does not boot from cd, the PRAM thing wont work, verbose mode or the comand + s mode wont work
I tryed clean install but it wont boot from dvd, also it will not boot in any other way
It was working perfectly last night and i just shut it down and it does not work know.
My friend was also trying to install Lion from his account but the .dmg for it did not open so we quit and that night i used it for my essay and finished and then i turned it off and next day in the morining it don't work
HELP ME PLEASE

You can take the drive out of the computer, use a $20 IDE/SATA to USB adpater to another Mac
You can see if you can read the drive directly to gain access grab files, run Disk Utility and perhaps it can repair it.
If you can't read the drive then there is DataRescue for a whopping $99 but it will read any deleted (but not scrubbed, encrypted or overwritten) data for recovery. Least that way you can get your files back.
Once your data is off, Zero Erase the whole thing, install 10.6 on it with the other Mac.
When installed in the sick mac, the hardware firmware will read the new EFI firmware, load it and you'll have the boot keys back again ON THE SECOND BOOT, it doesn't load on the first.

MBP won't boot - Grey Apple Screen, Spinning Wheel, then Shut Down

Help please
For no apparent reason, my otherwise well-working MBP (2007 model) simply won't log in to OSX (leopard). I try to boot it up, and I get the grey screen with the Apple logo, the spinning progress wheel, and then after about 4 minutes, it just powers off.
Thoughts?

I ran verify because the option to run repair was not available.
And just to make sure, you booted from the install disc? (Repair Disk is never available when booted on the boot volume of the HD.)
Here's a follow up... This mac wasn't doing it's airport backups properly,
I'm not quite sure what that means, maybe Time Machine? Time Capsule?
so I don't have a recent back up of the files. Would you suggest just sending the computer to a data recovery service?
Very expensive. Try FireWire Target Disk Mode first. If that doesn't work, I'd remove the HD, install it in an external enclosure (as low as $15) and see if it will boot the MBP or the data is accessible from another Mac.
Do you think I can just pop a new HD in it and it'll work fine under a full reinstall?
Doing my previous suggestions first may help to answer that. If there's absolutely nothing wrong with the HD, then that isn't the issue. If there is something wrong with it, likely a new HD is the fix.

My macbook will not boot past apple loading screen

Yesterday i turned my computer off before going to class, when i got back i was not able to get past the loading screen. I havent had any problems at all, many people have been saying that their macs start freezing then they have to manually shut down the computer. This usually means the hard drive is bad. but i have not had any of these problems. I am also not able to boot into safe mode. When i go into disk utility my hard drive shows up but is in grey, when i try to repair it it shows that its working but stays in the same spot for hours, i finally shut the computer down after 5 hours of it loading in the same spot. I have tried all of the commands suggested on the forums but have had no luck. I am also running lion but since their is no cd for lion would i use my snow leopard cd or the cd that came with my macbook in 2009. Sorry for the long post, thanks in advance!

MacBook Pro will not boot from Apple Logo Screen - No HD recognised

Hi all,
I encountered a problem booting my mid 2010 MacBook Pro yesterday. I currently run OSX Mavericks.
The computer has been great for the last 4 years and has never encountered any major issues. Yesterday I dropped it on carpet while sitting on the couch (it was a VERY small impact) and I continued to use it for a few hours. I did a safari update that night also. I then closed the lid which would have put it to sleep. My flatmate asked for a file later that night, I took his USB and stuck it in my computer, THEN opened the lid. The computer never booted up (It was stuck on the apple logo with the spinning thing underneath it). After doing this for a minute or so the computer would turn off. After multiple attempts the same thing happened.
I read many posts on this - I am assuming that the problem occured because I brought it out from sleep with a USB in the side. I have taken the following steps to attempt fixing the problem -
*safe boot - no luck
*reset PRAM - no luck
*recovery mode boot - getting disk errors.
In recovery mode boot I cannot reinstall a new OSX version because there is no internal HD disk mounted. It only gives me the option to install OSX to the Recovery HD, which is locked.
Using Time Machine backup wont work as there is also no Internal HD detected to load to.
In Disk Utility it no longer has 'Macintosh HD' - It is further labelled 'disk0s2'. I cannot verify, repair OR erase this disk.
Can someone PLEASE assist with what I might be able to do. I need to somehow mount/unmount/detect my internal HD. I am happy to detect it and format it as I have Time Machine backups on an external HD.
I am no mac genius although I do learn quickly. If I can get assistance It would be very appreciated. I have a feeling I can sort some issues out using Terminal although I need command assitance?!?
Apologies for the long post although I want to outline everything I have done to attempt to isolate the problem.
Thank you all in advance.

Does your flatmate have a Mac as well?
If so, you could always get a 8GB+ USB stick, download Mavericks using your Apple ID and use DiskMaker X to create a bootable installation disk on the USB stick. Then boot using the USB stick (hold down the option ey whilst booting to select it) and try to reformat your drive using Disk Utility and, if you're able, reinstall OS X on your machine and then restore from backup.
The only hitch may be that your hard drive is dead and that you need to install a new drive. You'll know once you boot from the USB stick, though, if you can format the drive or not.
Good luck,
Clinton

I'm running Windows 7 and occasionally, Firefox will become completely unresponsive and grey out, then none of my programs will open at all, including the Start menu, forcing me to use a hard restart and shut down. Any help would be appreciated.

I'm not able to close and restart Firefox at all, since the computer becomes completely unresponsive, save for mouse input. Task Manager is also of no use.

Ok, to copy the Drive from one to another, get carbon copy cloner to make an exact copy of your old HD to the New one...

Believe it or not, anything on the Desktop uses 3 times the Resources of the Mac than if stored elsewhere, I can note a slowdown from just 30 items on the Desktop on a really fast Mac, so the less the better on the Desktop.
DW will not tell you about Bad Sectors, it's just the very best at Repair Directory damage & such.
At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

Yosemite will not boot in apple diagnostics mode

I have a Mac Mini 2014 running Yosemite 10.10.2. When I try to startup in Apple Diagnostic Mode (D key held down at startup chime, all peripherals except for mouse, keyboard and monitor unplugged) the computer just starts up in normal mode. Any ideas as to why this might be happening? Thank you.

It turns out I had a Firmware Password installed so it prevented the computer from booting in different modes, including Apple Diagnostic Mode. Since disabling the password, everything works fine now. Thanks, mende1, for your help.

HT203254 My 15" MacBook Pro of about that vintage indicates that all is well by the hardware tests bu will not boot beyond Apple screen, stops with arrow and short horizontal lines.

What serial and model numbers were known to be Products Affected, MacBook Pro, models with NVIDIA GeForce 8600M GT graphics processors?

Welcome to the Apple Support Communities
Take the computer to an Apple Store because your graphic card is damaged. The computers affected were sold between May 2007 and September 2008, so if your Mac is one of these Macs, Apple will repair the computer for free

MacBook pro will not boot. I get the gray screen, an apple icon and spinning wheel. Tried to start in safe mode but get the same screen. The only thing different was that I loaded the zedge sync app yesterday. Now getting this problem.

Macbook pro will not boot. I get the gray screen, an apple icon and spinning wheel. I tried to start in safe mode, but get this same screen. The only thing different is that I added the zedge update app to do a sync for adding ringtones to my apple cell phone. How can I get a good boot. I am fairly new to apple computer.

Reset PRAM: http://support.apple.com/kb/PH4405 and then try a normal boot.
Run the Startup Manager to select Startup disk: http://support.apple.com/kb/HT1310
If those did not work your disk may be sick or dying. The top priority at this point is to make a backup copy of your data.
Check the health of the disk. Boot in Recovery Mode (Boot, Command-R). Run Disk Utility. Click on the upper left disk icon. Does the S.M.A.R.T. status say “Verified”? If not the disk/SSD is unhealthy and needs to be replaced. Even if it does not show “Verified” you can still attempt a backup.
Click on the icon indented below, usually called “Macintosh HD” and Verify Disk. If it finishes with a green “OK” message then all is well with the disk. If it shows errors in red then you have found a problem to address once the system is backed up. Do not attempt software repairs until you have secured the data.
If the disk will not show up at all in Disk Utility as your ran the tests above then it may be dead or it may have a bad internal SATA cable. A trip to an Apple store for confirmation would be in order.
If you have an external disk drive you can use as a backup drive then do so. If not Google “Hitachi USB 3.0 external hard drive 1TB” to purchase one or go to a brick-and-mortar store (including an Apple store) to pickup one. Any 1 TB external drive will do.
Assuming it is still breathing you can try to recover the data without booting from the sick disk.
Reformat the external disk. (This will erase all data on the external disk.)
Boot in Recovery Mode. Start Disk Utility. Plug in the new disk. Select it’s disk Icon (the second one down, left justified). Select the Partition tab.
Partition Layout > Single Partition
Name: Emergency Recovery 1 (or whatever name you wish to use)
Format: Mac OS Extended (journaled)
Options… > GUID Partition Table > OK
Apply
Select the Restore tab.
Drag the old system volume (Macintosh HD) to Source.
Drag the new disk volume (Emergency Recovery 1) to Destination.
Click on Restore.
It may take a long time for the backup.
If that will not complete post back for other emergency data recovery methods, including those from a brody.
If the backup succeeds, use the First Aid tab in Disk Utility to select the old volume (Macintosh HD) and Repair Disk. If it does not finish with a green OK message try to repair it once or twice more. If it repairs with a green OK message, will it boot normally? If not, boot from the Recovery Partition and reinstall OS X.
If it is still not healthy, post back for further instructions.

Windows xp will not boot up after installation of desktop software 4.3.

windows xp will not boot up after installation of desktop software 4.3. Where do I start to get my p.c. going again ???

I get the message that a recent hardware or software change might have caused this.
The computer does not boot up in safe mode or last known good configuration.
I'm glad you think the software has nothing to do with it, but perhaps you can also explain why this problem started as soon as I downloaded the desktop software and tried to restart the computer.

Will not boot up. Apple shows, spinning wheel shows, a bar comes up on the bottom. It gets to the end of the bar and shuts down.
