Macbook Pro won't start properly... keeps restarting without chime!

Macbook Pro won't start properly... keeps restarting without chime!
Late 2007 Macbook pro. OS upgrade worked great for me.
I have had this problem on and off for a month or so. I simply cannot figure out what the issue is. I have tried poerup with and without AC power and with/without battery installed.
Starting in Safe mode does not help.
Trying to start with a disk does not help.
It sort of seems like it might be an internal power issue or GPU issue.
It also feels sort of like a software compatibility issue since my Macbook Pro gets reallly slugish for no apparent reason sometimes and IU have to restart.
I have three different anti-virus programs so I doubt it is a virus issue.
I noticed all this start after I did a Mountain Lion upgrade and then tried to start up VMware Fusion. Fusion seemed to just bog down the computer horribly but did not cause a system crash.
I need to edit an important sequence on Final Cut Pro and don't want it to freeze me out!
Anyone who has had this problem and resolved it please let me know
God bless

My Macbook Pro won't shut down or restart without forcing shut down. Hangs on grey screen. iTunes not recognizing iPod.

HELP!!!
Here are the specs of my machine:
2011 13.3" MacBook Pro
4 GB Ram/320 GB HD
For the past several months my MacBook Pro refuses to shut down or restart without holding down the power button. Whenever I choose to restart or shut down the computer, it will hang on a grey screen. I have even tried letting it hang for an hour, and it still won't shut down. I notice that once in a while it will retart or shut down correctly if I had not used opened iTunes since turning it on. However, even manually closing iTunes before shutting down or restarting does not solve the problem. It seems as though it only shuts down if iTunes was not used since restarting the computer. Is this a registry error? Do I need to reinstall iTunes? I noticed this problem began happening after I uninstalled Kaspersky Virus Scanner, could that be the problem as well? Also, I cannot guarantee that the problem is only associated with iTunes. I just noticed that one of the few times it shut down or restarted correctly, iTunes coincidentally had not been used. Also, this problem started happening while I was still using Lion and has continued despite upgrading to Mountain Lion.
Also, whenever I update my iPod through iTunes, it won't eject properly, and a transparent icon of the iPod displays on the screen even after I have removed it from the USB port. Furthermore, the iPod will only be recognized by iTunes and will only be updated the first time I plug it in. After removing it and plugging it back in, it won't recognize or update the device unless I shut down and restart the computer. I have the latest addition of iTunes. I also have two iPods, one 80 GB Classic, and one 8 GB Nano, and I have the same problem with both.
I have AppleCare. Should I take my macbook to the genius bar?
Applications I normally use are Word, Safari, FireFox, iTunes, FinalDraft, Photo Booth, Notes, Mail, App Store, etc. No real heavy lifting.
Any feedback would be very much appreciated. :-)
Thank you everyone!!

I have this question too.

Installed Yosemite...now my MacBook pro won't start up. Keep showing "Kernel Panic!" HELP!

installed Yosemite and now my MacBook pro won't start up. Keeps showing "kernel panic"
PLEASE HELP ME!

If you can't start up and log in in the usual way, try in safe mode.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally 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.
Log in as an administrator to carry out these instructions. If you have only one account, you are the administrator.
☞ If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
Safe mode is slower than normal, and some things won’t work at all.
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 start in safe mode.
If you're able to log in, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.

My 2009 2.26Ghz MacBook Pro won't start up

My 2009 2.26Ghz MacBook Pro won't start up. I know it's not the HDD because I replaced it with the old one I had in it and it did the same thing. I also know it isn't the HDD because I can boot of of it when I attatch it via an external HDD enclosure. It sometimes turns on if I let it sit for 30 minutes and if it does turn on it works perfectly and has no symptoms until I close it then it freezes up when I wake it up and I have to hard restart it but it doesn't restart then. It seems to do this more so if I close it then move it (put it in my bag and go to school). It's getting me really upset cause if it's my motherboard it's $600 to replace (almost not worth replacing except I don't have $1400 for a new MBP) please give any advice. I thought about buying the data doubler by OWC but that would be a last resort. I upgraded the ram to 8gb, 1333mhz (I know it uses 1066Mhz but I couldn't find any where I live so I put in 1333mhz ram expecting it to underclock to 1066 which it seems to have done that with no issue to my knowledge just thought I'd add that in case though.

Sluggish could be due to not enough ram for what you want to do.
Keep working with it, you may need to put more ram in, but go for the stuff that meets the specs.
A much liked source on here is OWC, http:www.macsales.com you only have to look up your machine to get exactly the right stuff.
Get back with how it is working, would like to hear more.

MacBook pro won't start up.

The last two times I've been in Mexico City, my MacBook pro won't start up. I hear the chime and see the apple icon, but it just spins and makes a clicking sound. It works fine back home. I think it might be the altitude, but my husband's MacBook works. Help!
I tried restarting in the safe mode, but it only show the apple icon and not the spinning progress monitor. I don't have the discs that came with the computer here with me. Is there a genius bar in Mexico City? Any ideas to fix this?

sorry disregard this post. it's in the wrong forum.

My macbook pro won't start up. Instead of the apple logo appearing in the start up only a grey folder with a ? At the center appears

Boubert,
the question mark in the folder typically represents the inability to recognize a valid filesystem on the volume being booted from. You can try this, although it might not make a difference: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, select the First Aid tab if it’s not already selected, then press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Is it able to boot normally now?

Reinstall OS X:
Reinstall Snow Leopard without erasing the drive
Do the following:
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.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
Reinstalling 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: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

TS2570 My MacBook Pro won't start up.only gray screen

Hi there,
My MacBook Pro won't start it show only gray screen (with apple logo )
And I have tried these solutions none of them worked
1/ Reset PRAM and NVRAM
2/ Restart in safe mode
3/Run Disk Utility in Single User Mode
After I tried third option it shutdown by itself
Please I need data inside the laptop , i have no backup
what should I do ?
I need some kind of solution does not contain formatting or deleting my data
Thank you in advance

Create a data recovery/undelete external boot drive
My computer is not working, is my personal data lost?

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).

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!!!

Hi! My MacBook Pro won't start! HELP !!!

Hi! My MacBook Pro won't start! I have tried everything I can think of like Safe Mode (doesn't work), Recovery (does not find Recovery Drive), Booting with OS Snow Leopard Cd (doesn't work)...
I have really no clue about what to do now... I paid quite a lot of money for this computer and am pretty short of money nowadays! Would like to repair with help rather than having to take it to Apple Store.
Has anyone had this same problem?
All I get is white screen + grey Apple and spinning grey disk... it's 100% frustrating! Any help would be more than welcome since I think i've tried EVERY SUGGESTION on this Support Center and Youtube videos...
This MBP is from 2011, runs on OS X 10.6.8
I tried booting with OS X Snow Leopard CD, it didn't work! (my cd player works! recognizes the Snow Leopard CD, but then never opens it... goes back forever to the with screen + apple and spinning disk)
I don't care about the content, it's OK if i lose all DATA... I just want to bring this Mac BACK TO LIFE!
When i run coomand on root# fsck -fy --> RESULT = my HD was checked and seems to be FINE!
Thanks

Please make a Genius Appointment and take it in for service.

Spilled liquid on MacBook Pro - won't start - any suggestions?

spilled liquid on MacBook Pro - won't start - any suggestions?

Thank you both for your responses! I watched a video on how to remove the hard drive - special tork(?) screwdriver and too many steps for me to feel confident about doing it myself, so I took the computer to an Apple Store - and thank God, the hard drive appeared undamaged - they are transferring the data to a new Macbook Pro. The loss of data was the scariest part, so I am breathing again!
The laptop was three years old, I was hoping for another year or so before upgrading, but such is life. I appreciate your upfront advice.

MacBook Pro won't start after changing access rights

I did something very wrong. Unfortunately I changed the access rights of Macintosh HD for "everyone" to none.
Result, my MacBook Pro won't start anymore.
Already tried the installation disk, reset password for root and users. No result.
Help program "check acces rigths". Didn't work either.
How do I reset the access rights of Macintosh HD?
