MacBook Pro Failed to Start Up
Hi all, some advice required.
Last night my 2006 MacBook Pro did not start up. It hung on the grey apple logo then went to a black screen and kept trying to start. A message gradually counted down from 10 attempts to one and then the start process stopped to a simple cursor. There was some message about "throttling too quickly".
Following advice from a friend I reset the P-RAM and although the next start got beyond the grey apple logo, it hung on a blue screen. I then reset the SMC and the computer started just fine. It now appears ok.
Some History:
I used to have boot camp running Windows XP. When I started to run short of hard drive space I removed this. Ever since then, on start-up a brief question mark "?" appears instead of the apple logo. It is only for a moment. I read that this means something can be wrong with the start up process? Also when I install the firmware updates periodically from apple when the computer is required to be restarted it "hangs" on the grey apple logo and has to be shut down and restarted a second time in order to boot up properly. Two weeks ago my optical drive failed. It makes no sound on start up and will not accept a disk. When you go to "About this Mac" the computer says it has no optical drive installed. Could this problem be related?
Is my MacBook Pro on the way out? It will be four years old in January and has been used pretty heavily since I got it. I wanted to upgrade the RAM and install Leopard rather then spend all the money on a new one. Is this a waste if it's about to die?
That's a lot of info I know, many thanks in advace for your advice.
David
Boot into your Recovery partition (if you can) by holding down the command and R keys whilst booting. Once there elect to resinatll the OS (you may need your Apple ID and password for this). You'll not erase any data, etc., by installing a fresh OS.
Once your OS install is complete, you can restart and go through the update process again, this time remembering not to unplug from mains while the updates are installing.

MacBook Pro Fails to Start Up (Three Strange Beeps)
The MacBook Pro I've had since April of 2007 now won't start up. During use, the screen suddenly was crisscrossed with horizontal lines, and the screen and computer froze. Pushing and holding the power button didn't have any effect, so I unplugged it (the magnetic cord) and let the battery drain (which doesn't take long, since I'm pretty sure the battery is dead, and has been for several months). After letting it sit for awhile (unplugged everything), I plugged it back in, the gray screen came up with a start up chime, and then there were three loud beeps. The computer keeps running and trying to start up, I guess, but the computer screen stays gray. The light on the front of it flashes, and the green light on the power cord flashes green and then orange, and that's where it sits.
So. What's wrong, what can be done, etc.? It's hard to imagine that this computer which is pretty much exactly two years old is dead.Wow. Okay, I got the screw off, and took out the RAM and reinserted it, and that made it quite a bit worse. Now the screen won't come on at all; it's completely black, even though it sounds like it's starting up. The white light on the front of the MacBook (where you open it if it's closed) blinks continuously.
Update: Took out the RAM and reinstalled it again, and now it's back to the original error described in the first message.

It's hard to describe the symptoms, my mac froze using chrome and failed to restart. It wasn't even a dodgy website either, it was a law firm's.
The grey screen starts fine, but when the desktop should appear I get the following 'broken' screen.

One would think it's a graphics problem but the spinning disc is fine. Similarly a safe mode start does bring the desktop up.
A third party would therefore be the problem then, however I haven't installed any software on my machine in a long time so I am at a loss to the cause?
It may be worth noting the fan is running very fast and the machine feels hit even after a cool down and restart.
Can anyone help? Thanks.Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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 Utilities menu. 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.
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. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Stop using Chrome. Stick to Safari if you wish to have fewer issues with your computer. -
After having to do a forced shut down (holding down power button) due to freezing I cannot again progress past the grey screen with the apple logo. The spinning cog comes on at first then disappears leaving just the apple logo (in case that is sognificant).
I have tried to find a solution through the support pages but have unfortunately been unsuccessful in my endeavours so do apologise I have overlooked the obvious and would really appreciate some help. I've just started the second year of my Uni and the timing couldn't be worse.
I have tried the following:
1) held down option and started in "recovery 10.8.4" from which I used disk utility to "repair disk", which at first needed some repairs and then I ran it again for the second time to confirm it had a clean bill of health.
2) I then ran "repair disk permissions" and repeated a second time to confirm it was all working well (however one error remained "warning: SUID file "system/library/CoreS... has been modified and will not be repaired" but have read that this should not be a big problem) After which I tried to start up again and it hung with the apple logo on the grey screen.
3) tried resetting the PRAM by holding down cmd+option+P+R before powering up, but it only chimes once and then restarts the mac, then chimes once and repeats the process again in and endless cycle.
4) I then tried 1 and 2 again and then tried to reinstall OSX 10.8.4 from the recovery mode, but this came up with the message "could not find installation information for this machine".
5) I tried starting up in safe mode by holding down shift after the chime at startup but safe mode did not start after leaving it 3 hours.
6) I tried starting in verbose mode with cmd+V but after running the script it reverts back to the grey screen.
I hope I have explained it in enough detail and appreciate any direction or thoughts as to it being salvageable and what to try next.
Many thanksEric
Thank you for taking the time to post those links to informative articles.
In relation to the first article entitled "Resolve startup issues and perform disk maintenance with Disk Utility and fsck"
I can confirm that i was not able to start in safe mode but was able to boot up in recovery mode and run disk utility. The only one i hadn't tried is fsck. Please correct me if I am wrong, but if from what I understand by the article, this is to be used if I could not run disk utility, with which I have been able to do and to repair both the disk and permissions. But again, if I've missed the obvious from that article please correct me.
Te second article entitled "Troubleshooting Startup and Login Items" identifies troubleshooting that should be carried out in safe mode. However I am unfortunately unable to start in safe mode and have not been able to progress past the apple logo since this problem started.
Thank you for both links and for taking the time to share. If though I have missed something more significant in this regard I would appreciate your feedback.
Many thanks -

TS3423 17" macbook pro won't start blue file with question mark is all that appears on the screen
My old macbook pro will not start up. Worked fine yesterday, today all I gat is the startup sound and a blank blue screen. After a while the screen shows a file folder icon with a question mark in it. Any ideas
Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by:
Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
Boot drive's directory has been corrupted - Repair with Disk Utility.
Critical system files are damaged or deleted - Reinstall OS X.
The disk drive is physically non-functional - Replace the hard drive.

The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD:
Boot From 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.

Since you can boot into safe mode successfully, I'm assuming the problem may be with a bad third-party extension or plug-in (such as a driver for third-party hardware or a bad Flash plug-in, for example.) It can also be a problem with a bad cache or preference file. If the above doesn't help then use a utility like Lion Cache Cleaner 6.0.5, Cocktail, TinkerTool Sys..., or OnyX to clean out user, system, and font caches. -

MacBook Pro has recently started to crash.
My MacBook Pro has recently started to crash. It sometimes crashes when watching streamed video (youtube/netflix), and will always crash when using high processor programs (e.g. final cut X, Logic Pro) and cannot run any games without crashing. Usually starts running hot before cutting to a blank screen (and any audio starts to loop), and requires a hard reboot.
Any help would be apreciated.
below are the latest error report, and hardware copied from settings.

You probably have the issue addressed by that article.
Take the computer to Apple or an authorised repairer, tell them that you think it may be the problem mentioned, and they should run a simple pass/fail test.
The service is only for three years after initial purchase, but several users here have reported getting free repairs even after that limit, sometimes after contacting Apple customer relations, pr speaking to an Apple store manager. -
My macbook pro won't start up. I get the white screen and the grey apple icon the spinning wheel......and it doesn't change !
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. -
My MacBook Pro won't start up. What do I do?
My MacBook Pro won't start up. What do I do?
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities 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.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities 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. Select Restart from the Apple menu.
Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, 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.
Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo). -
My Macbook Pro won't start up. All I get is a grey screen showing a grey folder bearing a question mark. Help please!
The folder with the question mark indicates that the machine is unable to find a bootable volume on startup. This is typically caused by one of three things:
1.) The internal HD has failed or is failing and needs to be replaced
2.) There is significant directory damage to the volume that requires repairing in order to boot
3.) Some other internal component failure between the HD and logic board
I'd ranked them in the order that is most common (from my personal experience). Boot to the OS X Recovery tool and attempt to repair the startup volume. If that fails or the drive is not detected it's usually a tell tale sign of a failed HD. -
MacBook Pro does t start I turned it off during start up I've tried a lot of stuff. When I hold startup my hard disk says efi boot instead of Macintosh hd
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.
If this does not work, then you will have to erase and reinstall Mountain Lion:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless. -
I was messing around with .kext files in the MacintoshHD and now my MacBook Pro won't start up.
I was messing around with .kext files in the MacintoshHD and moved the system.kext and two others to my desktop and deleted the originals and now the MacBook Pro won't start up. All I get at start up is the apple icon then a bunch of text shows up part of which says Mac OS version: not yet set. then the apple icon turns into the power icon and tells me to turn off the computer. I've tried reinstalling from the install DVD by holding down option when powering on and selecting the install DVD and it just goes to a white screen with the apple icon and stays like that. I didn't have the disk utility on my Mac before this happened because I deleted it to make room on my computer a while ago so I'm not sure if that's why it won't load the install DVD but anyone who knows the solution to this with out going to get it repaired would be greatly appreciated. Thank you!
Never mind my dad just found the original install DVD and that worked. Before I was using an install disc that Apple sent me for another issue I was having, but thanks for replying so quickly and trying to help on this Thanksgiving day!!!
